Different Types of Projection Screens

Many people like to have a video projector system at their home so that they can enjoy the feel of a movie theatre within the comfort of their living room. For building up a good projection system, not only is it important to get a nifty projector, but also to buy an optimum screen.

In the market of UK, projection screens are available in many different types. Let’s have a look at some of the most common ones:


Front projection screens are very common in UK. They are mostly used because of the fact that they can be set up very easily. They also save a lot of space and do not require a dedicated room for the video projector system to be up and running. Since their viewing angle is very wide, they allow the casting of larger images efficiently. They are portable and cost effective solutions for a video projector system that has to be built up with a tight budget.


A rear projection film in UK is a good alternative to the front projector ones, as people from the audience would not be able to block the projection accidentally by getting between the film and the projector. The image formed on a rear screen is also very crispy and clean, but it would be visible only if the space between the screen and projector is entirely dark. Therefore, it is important to have a dedicated room with a considerable amount of space within.

Permanent screens are those which have either been built on the wall of a room or mounted. They remain in sight at all times, but are a wise choice if there is a particular room designated to be used for home theatre entertainment. However, one should invest in a permanent film if they wish to use for other purposes.

Pull Down

Also known as retractable films, pull down screens are very space effective as they do not block any space inside the room and can be kept hidden from sight mounting from the ceiling. After use, they can be raised up in a safe case. Pull down films are quite cheap as well.


These are motorised pull down screens that can be lowered and raised just by hitting a button or wall switch. Some projectors are also designed to control the screen, lowering it down when on and raising it up when off. However, they are costlier compared to the ones which can be regulated manually.

Multi Room Audio: Ease To Listen Pleasant Music Anywhere

Basically, it means that the whole family can listen to their own brand of music, without interrupting the other members of the family, for example mom can listen to her soft music while she is working in the living room and dad can relax with oldies or classic tunes in the bedroom, the kids can use their iPod in their own room.

The Multi Room Audio unit is installed in one place, it usually is put inside the wall, what is visible are stylish ‘speakers’ and ‘keypads’ that go with the other furniture in the rooms.

Multi room audio system comes in many famous brands. Most of the systems are user friendly and can be installed without any hassles. There are many types of Distributed Audio systems available in the market and it is important to learn more about them before taking a decision to buy the system. Basically, there are multi room audio systems that work with receivers, with wiring used for networking and wireless system that is used for distribution of music.

  • A Receiver is used for a single source or multi zone systems: A speaker switch that is already working with a stereo / receiver for home theatre is used for the single source system. Additional speaker wires are installed in other rooms and viola a multi zone system for listening to music is up and working.
  • One receiver is used with more than one source or multi zone systems: The new theatre system comes with a receiver system that has some extra features that supports multi zone and multi source functions. It can be used as a channel to provide music to many zones or areas in the house.
  • Safety Precautions: There are some precautions that need to be taken for the installation of multi room audio system. Care needs to be taken to put the receiver away from the radiators and heaters.
  •  Use of WiFi in multi room audio system: The use of WiFi or wireless connectivity is the latest trend that is adopted by a majority of people. Wireless speakers that are compatible with each other are connected by a wireless network.  The other option is to use Bluetooth technology to constantly stream music from one audio source to the speakers.  The audio source generally is a smart phone.  This system connects two or more rooms in the house.

There are many ways to install a multi room audio system in a house. One can use a receiver for a single source with a speaker switch, when the receiver is switched on it can work in all rooms of the house.  Wi Fi connectivity is the latest way to have a multi room audio system without wires, plugs, and receivers; it works efficiently and makes the place look neat and tidy. Smart and quality living is a dream of each family and multi room audio system helps in creating an atmosphere in the house that is relaxed and happy. For grabbing Home Theatre Speakersor any other classy accessories

Concepts Of The Top Computer Engineering Schools And Its Application

Technology has become a part of our everyday life. There are a number of schools, which offer computer engineering. They educate as well as conduct research covering wide areas of information science based on fundamental technologies such as database system, internet technologies, computer architecture, discrete mathematics just to mention but a few. These schools provide attractive educational programs based on computer programming.

The basics of technology help the students to be the leading engineers as well as researchers who are highly motivated and who have creative, practical and management skills to drive an advanced next-generation information society in all industrial fields. Therefore, computer engineering is the branch of engineering that incorporates electronic engineering with computer sciences.

Top computer engineering schools use many of the principles and techniques of electrical engineering as well as many of computer science. Computer engineering focuses on crucial aspects that enable the students to understand and advance in the new emerging systems. Computer engineers are in most instances concerned with analyzing as well as solving computer-oriented problems. It is evident that computer engineers improves the ability to make computers more mobile and even incorporating computers into clothes, fabrics as well as building materials.

Computer engineering concerns with the concepts of technical and scientific knowledge while applying science and mathematics purposely to efficiently and effectively conversion of natural resource and the manipulation of information for human benefit. However, the concepts of computer programming in schools are a dynamic profession. Educationally, the scientific principle on which computer engineering is evaluated depends on the consideration of the application of computers and their primary focus.

In conclusion, computers are fitting very essential universally. Most schools are using them, since records are being stored in computer files and stores are taking their business online to sell to a broader audience. All of these are potential because of Computer Engineering. If some extremely important changes are made in the syllabus, more students will be fascinated to the major allowing it to thrive even more. If students have the capability to learn what they need to know about computers, they can go on in the job market and optimistically becoming very successful. There will always be a rising requires for people who can work with technology, make it enhanced, and even devise new tools to work with it, which is why it is a foremost that could actually have a vivid future if it stays at the schools.


Do you Know What a Transputer Is?

The transputer (TRANSistor comPUTER) was an innovative computer design of the 1980s from INMOS, a British semiconductor company based in Bristol. When the transputer was first reveiled, many thought this exceptional concept should be the next revolution in microprocessor technology. As you may already have guessed, things didn’t happen as expected: today, the transputer is a largely forgotten concept (although some initial ideas may be found in modern processor architectures).

In the early 1980s it became clear that conventional CISC processors were very limited in terms of scalable performance. One concept to solve the problem was RISC, which became the defacto standard for high performance workstations in the late 1990’s. As RISC architectures were quite expensive in most cases (although ARM was not), the transputer was intended to offer high end performance without being costy.

The idea behind the transputer was quite simple: instead of creating a very complex processor, the transputer consisted of a family of chips. Each chip had a very simple design and multiple chips could be wired together to form an entire computer. Each transputer chip was in fact some kind of a microcontroller and was able to boot and operate by itself, it had its own RAM, a serial bus and an embedded real-time OS, but it fulfilled only very few complex tasks. Computer vendors would then combine transputer chips like building blocks and design a system that would fulfill specific requirements.

A single transputer chip could be used to power a disk controller for example, while larger numbers of them could be used to create a high end workstation. The advantage of the design was its extreme scalability and its low cost hardware. The transputer chip core itself was a simplified, microcoded CISC-like 8-bit processor (it ran a real-time OS to control the processor), while the available processors can be categorised into three groups: the 16-bit T2 series, the 32-bit T4 series and the 32-bit T8 series with 64-bit IEEE 754 floating-point support.

The transputer was a parallel architecture by design, and it required a multitasking operating system to take full advantage of the transputer hardware. Transputers were intended to be programmed using the occam programming language, which had also been developed inhouse at INMOS, and allowed to directly take advantage of the transputer hardware design. Later on other languages such as C, FORTRAN, Ada and Pascal became available too.
One of the major disadvantages of the transputer was the lack of an MMU or virtual memory support, which prevented UNIX to be ported to the transputer architecture (although there were ports of some UNIX-like OSes).

The first transputers were announced in 1983 and released in 1984, and various models followed during the later 1980’s. The final problem of the transputer may have been that it was still too costy to compete in the microcontroller market, while it coulnd’t complete with the growing success off the high end RISC designs. At the end, the was no real market for the transputer.

After many technical problems and delays during the development of the next generation T9000 transputer, INMOS got into financial trouble and was finally sold to SGS-Thomson, whose focus was the embedded systems market, and eventually the T9000 project was abandoned.

The most well known machine may have been the Atari Transputer Workstation, which was first introduced at the November 1987 COMDEX under the name Abaq. It was basically a modified Atari Mega ST with 512kB of RAM connected to a 20 MHz T800-20 transputer board and 4MB of RAM, plus a Blossom video system with 1MB of dual-ported RAM. A fully equipped Atari Transputer Workstation could contain 17 transputers offering 10 MIPS each.

Atari used HeliOS as operating system on this machine, as UNIX could not be ported because of the lack of a transputer MMU. Nevertheless this allowed the Atari Transputer Workstation to run a large number of standard Unix utilities, including the X Window System as the machine’s graphical user interface (GUI).

Advantages of Laptops Over Desktops


There is no denying in the fact that the world we live in is full of gadgets everywhere & we make sure that each & every gadget that comes into the market should be superior from its predecessor. Out of the gadgets there is one gadget which makes their presence felt from the very beginning & we as a people chosen it into one of our basic necessities.

Out of such gadgets we’ve laptops which we are using in our day to day life in office, cafeteria, home & many other places. Sometimes we feel that we should stop using desktop & instead replace all over with laptops. There are several advantages of laptops over desktop.

1. Mobility

 Don’t you feel that you should pull computer to your way instead of pulling chair to your computers? Well, if you’ve laptop then you have the option of bringing them closer to your favorite spot. Imagine if you want to chat or go through some of your favorite articles lying on your bed. As it works on battery so you can travel with it where you want, this will allow to check your mail or shop online anywhere.

2. Better displays

Now with advanced technology we can get better display in laptops than desktops which are great for your eyes also. The quality of laptops display is improving day by day, there’s hardly any difference between laptops and desktop displays. 3D, LCD, LED displays are also available in laptops for some famous brands.

3. Better Battery Power 

Previously there were some disadvantages of laptops i.e limited RAM, limited space of the hard drive and small life of its battery. But engineers has over come some of the disadvantages and slowly as time passes new and better laptops will be available with long life battery power, more space on hard drive and improved RAM too.

4. Lighter Weight

Laptops were little heavier when they first launched but now days you’ll see so many laptops which are easier to carry & you’ll feel comfortable at your back. Latest laptops are very much lighter compared to the laptops in olden days. The MacBook is slightly over an inch thick and Toshiba weighs is about four pounds.

5. More Features

In older laptops, the computer’s size and weight limited the number and types of features available. Today, with smaller processors and other components, there’s room to pack more features into notebooks. For example, the MacBook has a DVD player, built-in webcam, built-in wireless capability, two USB ports and a FireWire port, built-in microphone, and audio and digital input/output.

So above are some of the benefits of having a laptop instead of desktops. This may help you in choosing the better option. 

How To Connect Two Computers (Dual Screen) Over Network

How to set up a Dual-Screen workstation with an additional computer.
What we try to achieve: connect a laptop or another computer to an existing computer and have the ability to control both computers with a single mouse and keyboard. (Without any hardware, but over the network)

If you have another laptop or a pc computer sitting around and is wondering how you can connect the two computers and use each computers’ own processing power individually to multi task and speedup your working environment, there is a very easier way to accomplish this dream of yours. In today’s blog post I will cover all the possible ways to achieve this.

If you do have a dual display supported video card, what you will be doing is using a single PC and spread out the processing power between activities and expanding the working area horizontally, with the use of an additional screen. But what we are trying to do is take advantage of two separate high speed computers and use their individual processing power separating while having the capability to control them with single input devices and eventually setting up a DUAL-Screen workstation.

Option 1: Maxivista.com
The program available on the site is non freeware software and has all the capabilities we are interested in, dual screen, single control, and mirror screening, all the functions done over the network. So if you want to pay some extra bucks for few more extra features, this is your best bet.

Options 2: vnc programs
You can use win2VNC and a VNC program such as ultraVNC, RealVNC, or TightVNC to accomplish the single input control feature.
Links: http://fredrik.hubbe.net/Win2VNC.exe – win2VNC

Instructions for usage: you will have to install win2vnc on the computer that you wish to have the control and a VNC program on the other computer which you are going to be controlling using the other computers’ input devices. Both computers have to be connected to internet and relevant IP address will be shown after the program in run, which later will be needed in connecting each other.

– Share input devices (Mouse, keyboard) to control both computers and clipboards.
– Use each computers’ own processing power to perform tasks, yet both are connected together to allow single control.
– Dual monitor setup/workstation

– Most of the VNC programs I tried excluding maxivista do not allow mouse scrolling function on the controlled computer, but only on the controlling (main/server) computer.
– Even though both computers seemed connected, you are only controlling the computers, thus no applications or windows can be shared. This is what you have to really understand, each run on its own.
– You can not transfer files between two computers using these VNC programs although you can use other file transfer programs such as teamviwer etc. to connect the computers and transfer files.

Option 3: using hard ware gadgets.

FYI: This feature is knows as FVM which stands for Keyboard, Video, Mouse control. Mostly used for controlling several servers with a single mouse, keyboard and a monitor.

Surround Sound Wireless Speakers – Are They Worth It?

The goal of a surround sound system isn’t just to provide volume, it’s more concerned with creating a sound field which envelops the listener, generating ambience and providing directionality to a film’s sound effects, in other words, making you feel like you’re at the center of the action. In order to produce surround sound, you need multiple speakers (normally 6 or 8), linked to a receiver/amplifier. The most popular systems use a subwoofer for producing base sounds and 5 smaller speakers for the other channels. Some people think so-called 7.1 systems (which have two extra rear side channels) produce a more immersive experience; others think that the extra expense is not justified.

Whether you choose a 5.1 or 7.1 surround sound system, dealing with all the wires can be a bit daunting and require a certain amount of effort if you want a good result. With 6 or 8 speakers involved, there are a lot of cables to manage. Surround sound wireless speakers can help to reduce the cabling problem. Although fully wireless systems are all but impossible to find, there are many options on the market which offer wireless rear speakers. This does away with having to trail long wires to the back of your room. Wireless speakers function just like any other loudspeaker, and aren’t any more complicated to set up than regular wired speakers. However, if you’re hoping to completely do away with cabling, then you are going to be disappointed — the speakers will be powered by their own separate amplifier, and therefore require a power connection. Another possible drawback is slightly impaired sound quality, though with good models this may not be noticeable. For many people however, this is a small price to pay for having fewer cables to try and hide.

Despite their limitations, wireless speakers are still very popular among consumers and the number of models available on the market is growing all the time.

Put Computer Technology into Practical Teaching

In today’s technological world, you know how important it is for students to use computers on a regular basis. The challenge is to use technology effectively to enhance learning. Incorporating technology into your daily lessons and activities is a practical way to teach students that computer skills are important for more than just surfing the Internet. In particular, the PowerPoint is the most important tool that more and more teachers used in there practical teaching in order to make insightful visual experience and make student focused!

A slide show can present and illustrate an event in history, or explain a geometric proof in math. It can illuminate an oral book report, or report the results of a science experiment. Teachers use slide shows as backdrops to their lectures, students use them to deliver reports, and schools use them to show the community what they are doing. A slide show can be a valuable tool for teaching, sharing and learning.

I was always interested in helping students make real-world connections in project-based curriculum. With the increased availability of computer technology and Internet resources, I saw an even greater avenue for instruction.

How can we change this terrible situation?  Do you have a suggestion for educators?

We think that good teachers will always be good teachers no matter whether they use PowerPoint or not — are they able to keep students’ attention? I use PowerPoint in all my classes and students often tell me how interesting the classes are. It’s the PowerPoint that makes students bored, In my personal experience, I create a PowerPoint for my lesson plain with a powerful assistant which is PowerPoint to video converter software, it is a nice aid that I can create attractive Presentation and convert PowerPoint to video format, then I can play it on PC, and upload it to teaching website for download! It is a nice ideal!


It will help you create captivating and attention-grabbing classroom presentations using Microsoft PowerPoint. You’ll learn basic PowerPoint skills such as creating slides, using templates, inserting text, changing background colors, creating WordArt titles, and adding slide transitions. You’ll also develop advanced skills such as inserting graphics, sound, and video, custom animations, timed transitions, and hyperlinks.

You’ll be able to publish your presentation on a school Web site or even take your PowerPoint shows on the road. You’ll also be able to create presentations filled with scanned drawings created by your students or digital photograph slide shows. This class will assist you in learning these skills.


By using PowerPoint to video tool to create your presentation, you can maintain a record of the material that you cover during the school year. Students who miss lesson topics, or have difficulty understanding them, can easily revisit them later, by adding intuitive audio and animation to make the students understood and accepted more efficiently. Of course, there are plenty of other factors outside of multimedia presentations that affect student learning. It’s safe to say a teacher’s skills are still more important than the visual method used to deliver the course’s curriculum. Nevertheless, we can all use a little help with our teaching, and a PowerPoint slideshow that enhances, rather than detracts from or slows down, the learning process is all to the good.


In working with teachers to develop curriculum for the World Wide Web, I have organized my instructional approach into five basic phases: planning, research, development, refinement, and implementation. These five areas work as organizational frameworks for instruction and learning, curriculum development and implementation, student progress and presentation. It also frames the use of computer technology tools with a specific purpose. The goal is not solely to learn how to make a concept map with great pictures or to develop an attractive Web site, but to imbed the use of educational technology within a task. In this way, the tools enhance and facilitate the learning process. This gives the learner a reason to use the application, and along the way, the learner understands how the application works.

By teaching your students to explore how different features of a given technology can help them succeed, you can make using technology a consistent and easy part of your students’ learning experience. We should continuously explore the advanced teaching method to help our educators and student make studying more effectively and perfectly.

Route 128: Birthplace of the Digital Age

When most people are asked to name the location of the Digital Age, the first place which comes to mind is Silicon Valley. While Silicon Valley has certainly played a key role in the Digital Age, its birthplace was 3,000 miles East within a circumferential highway around Boston named Route 128.

The original analog and early digital computers were built by companies during the 1950s which set up operations in the Greater Boston area. Major companies located in the broader Route 128 area included  Digital Equipment Corporation,  Data General,  Thermo Electron Corporation,  AnalogDevices,  Computervision,  GTE,  Polaroid,  Sun Microsystems,  BEA Systems,  EMC Corporation, and  Raytheon.

“The Magic Semicircle”

In 1955, Business Week ran an article titled “New England Highway Upsets Old Way of Life” and referred to Route 128 as “the Magic Semicircle”. Magic referred to the nascent computer science companies which emerged to change the world forever.

A key resource in the Boston area is MIT, as well as Harvard and several other universities that have developed technology expertise in specific areas: Boston University in photonics, for instance. Graduates of these institutions founded groundbreaking tech companies such as Digital and Data One. The founders of Digital Equipment were alumni of the Digital Computer Laboratory at the Massachusetts Institute of Technology (MIT)

Digital, located in Maynard, MA is best known for introducing the minicomputer to the information processing industry, a development that altered the way potential customers perceived the computer. In defining the needs of a new generation of computer users, Digital set the stage for the development of the personal computer and the workstation. In 1960 the company introduced its first computer, the PDP-1 (Program Data Processor). The PDP-1 came with a cathode-ray tube (CRT), a screen which allowed the user to see what was being entered and received from the central processing unit. Unlike the room-sized mainframe computers of the day, the PDP-1 was no larger than a refrigerator. In the fall of 1965 Digital unveiled the PDP-8. This machine triggered the explosive growth of the minicomputer industry, and the company grew from a small technical company to a major computer manufacturer.

Digital’s competitor, Westborough based Data General-One, was one of the first minicomputer firms from the late 1960s. Three of the four founders were former employees of Digital Equipment Corporation. Their first product, the Nova, Data General-One, made it one of the first minicomputer firms from the late 1960s. The Nova was a 16-bit minicomputer.

By the ’70s and early ’80s, the computer architectures driving the industry were developed by people working in companies such as Digital, Prime, and Data General. With the overwhelming dominance of the PC, however, the center of heat and light for the PC is Intel as the microprocessor provider and Microsoft as the operating system provider.

These computer technology companies were the key generators of economic growth in Massachusetts during the 1980s. The term “Massachusetts Miracle” refers to a period of economic growth in the state of Massachusetts during most of the 1980s. Previous to this, the state had been hit hard by deindustrialization and resulting unemployment. The growth was heavily centered in high-tech industry and financial services, within Boston and in its suburbs along Route 128. The expansion of the high tech industry along MA-128 has led to the term “128″ meaning more than just the road itself, but the technology area as a whole, much like Silicon Valley.

20th Century Business Model

The early success of Route 128 was their innovative technology and management style. Though cutting edge for it’s time, most companies lost their competitive edge by the mid 1980s. Digital is a good case study. Digital’s customers were mostly scientists and engineers who did not require technical support, the company provided virtually none of the software and maintenance services offered by its giant competitors. Digital did not spend its capital on software design and maintenance services, and passed its savings along to customers. With its lion share of the workstation market, it was content with its dominance in the core minicomputer market. However Digital was slow to adapt its product line to new markets.

By 1990, companies such as Digital, Data-One and Wang were unprepared for the 21st Century and the advent of cyberspace. Though Norwood, MA based Wang enjoyed far more success in the PC market, it succumbed to a hostile takeover. Digital had ignored IT consultants and trend analysts who predicted the old mainframe model was fast becoming obsolete.

IBM, which invented the PC, saw the potential of the consumer market for computers after the Apple company sold its first computer in 1978. The Route 128 companies lacked the vision to look for market other than big business as well as other software and hardware engineers.

Silicon Valley, in contrast, was ahead of the curve regarding the consumer computer market. Intel made strategic partnerships with IBM and other PC manufacturers, as well as partnering with Microsoft which placed Silicon Valley front and center of the the dot com boom.

Route 128 Today

Today, according to economists, venture capitalists, and technology executives, Boston’s strength lies in fields like Internet software and biotechnology, which are fueled by the concentration of talent flowing out of MIT, Harvard, Boston University and others. A 2004 study by MIT and the Bank of Boston, an early national review of the economic impact of a research university, found that MIT graduates and faculty had founded 4,000 companies, employing 1.1 million people and generating $232 billion in worldwide sales. If the companies founded by MIT alumni formed an independent nation, it would be the 24th-largest economy in the world, somewhere between South Africa and Thailand, the study said. Massachusetts has the highest number of patent applications per capita of any state. There remains, however, no comprehensive report of these figures since the Panic of 2008.

Greater Boston remains a global technology hub. It has a healthy competition with Silicon Valley. IBM’s Lotus Development Corp., based in Cambridge, is holding its own in groupware vs. Netscape and Microsoft. EMC Corp. in Hopkinton, Mass., is the world leader in computer data storage products and is on the leading edge of cloud computing. Open Market Inc., another Cambridge company, is successfully competing against Microsoft and Netscape in selling software for electronic commerce.

Boston’s greatest strength is that it remained relatively unscathed by the Dot Com Crash of 2000, which left a devastating impact on Silicon Valley in terms of the number of lost jobs. Another asset compared to Silicon Valley is Boston’s lower cost of living. Most of the companies are accessible by Boston’s old yet efficient public transit. While commercial and residential rental rates remain high, the cost of renting an apartment in Somerville or Medford is lower than in Silicon Valley. Even in the current turbulent housing market, housing prices in Greater Boston are competitive with Silicon Valley.

While Boston remains in the shadow of Silicon Valley, it shows no sign of disappearing as a region of IT innovation and development.

Portable Overhead Projector – Which One Is Right For You?

A portable overhead projector is a very reliable type of projector that can reflect images onto a wall or a projector screen. They are made up of a large box with a cooling fan and a very bright light. They have an extended arm above it and at the end of the arm there is a mirror that catches the light and reflects it onto the projector screen.

The main use for the portable overhead projector is to enlarge an image and to display it onto a wall or a projector screen for an audience to view. A transparency is placed onto the overhead projector and it can be seen when projected onto the desired surface by the audience as well as the speaker. Although these kinds of projector were once were very popular in both business meetings and school classrooms, their use has been in decline recently as computer based projectors that are more sophisticated seem to be favoured.

One of the first uses of the portable overhead projector dates back to World War II when it was seen as a great tool to aid the training of large groups of servicemen. During the 1950s and the 60s the overhead projector started to be used in the school classroom. Here it was used as a tool for educational purposes and then it crossed over and was used as a training tool in the business world. In the 1990s the overhead projector reached its peak in sales when virtually every business and classroom in America was using one.

The best use of a portable overhead projector is when the screen or wall is around 2 to 4 metres (about 6 to 12 feet) away from the projector. There are some custom built overheads that allow the distance between the projector and screen to be increased but the cost of these can be much higher than the standard ones. For ease of moving the projector around they can be placed into an overhead projector cart.

The type of optics used can be seen as the biggest difference between different models of overhead projector and here are some of the main types that you can use:

Folded Optics or Chamber Optics.

This type of optic has a mirror between the lamp and the lens. Some of the benefits of using a folded optic projector rather than using the more common direct optic projector are the resolution is much clearer and there is a lot more light used to project the desired image. The light available with a folded optic projector is approximately 50% more than with a direct optic projector.

The Reflected Light Optic.

The lens of a reflected light optic is specially designed and it is backed by a mirror. The light source directs light to the lens and then the light gets reflected by the mirror. The reflected light gets directed back through the lens and then onto the main projective lens. Then the light is focused to a second mirror and finally onto the wall or projector screen.

A portable overhead projector is most likely to use a reflected light optic, with the cooling system, the light source and the main projection optics sitting neatly in one unit. This way the whole unit can be folded down and put into a case for ease of portability.

In order to get the most out of your overhead projector when making any kind of presentation you ideally need a portable overhead projector, an overhead projector cart and a projector screen.

The overhead projector is not as popular as it used to be when it was at its peak, but it is still in use in many business meetings and classrooms around the world. Although having said that, lots of users still prefer to use this type overhead projector in favour of the more sophisticated projectors because they are more reliable and a lot easier to use.

Guidelines for Buying Video Projectors

Video projectors are extensively used for personal entertainment as well as business communication. These projectors can make live display of computer screen over wall or screen. Some of the well known brands of digital projectors inIndiainclude Acer, BenQ, LG,Hitachi, Sony, Toshiba etc. Projector price inIndiaranges from INR 30,000 – 2, 50,000 depending on the technology used in it. If you are planning to buy new projector, following guidelines will be helpful for you:

Choosing the right technology

There are mainly three types of projection technologies that includes LCD (Liquid Crystal Display) projectors, DLP (Digital Light Processing) projectors and LCOS (Liquid Crystal On Silicon). Among all of these technologies, LCD is the oldest and LCOD is the newest technology used for projectors. DLP and LCOS projectors utilize much complicated technology and are available at high projector price. Such projectors are much preferable for corporate use.

For those who want home projector at cost effective rates, LCD technology is the best. As LCD projectors are available at cheapest projector prices, these projectors are widely used as home projectors.

Checking the portability

Portability is one of the crucial factors to be concerned while buying video projector.  Specially when you are buying business projectors, they must be easy to carry from one place to another. Portable projectors are also easy to install and are available at affordable projector prices. Ideally a portable projector should weigh less than 4lb. If you have no plans to travel with your projector, still you want easiness in moving it from one room to another, you can get many choices ranging in 10 to 15 pounds in weight.

Consider brightness levels

While selecting a projector for your room, you should consider the brightness level it provides. Brightness is typically measured in ANSI lumen. If the room in which projectors is to be placed is smaller or average in size; 1000 or 1100 Lumens is the minimum. However, if projectors are to be placed in large rooms such as conference halls, small auditorium, they require at least 1500 or more Lumens. Projector price will increase as per your requirements.

Know the right resolution

Resolution is an important factor to be concerned to take decision of buying video projectors. There are typically four main categories of resolution including UXGA, SXGA, XGA, and SVGA. Usually, how much resolution should be chosen depends on how much you can afford to have. Ideally 1024 x 768 (XGA) is considered as standard graphics resolution for any video projector and  1280 x 1024 (SXGA) is considered as high-resolution.

Check Contrast Ratio

Contrast ratio compares brightest whites to the darkest dark. The larger the difference, the richer will be the image.

Connection alternatives

It is important to check the number of connection options available with the projector. Typically, the more is the number of connection, the better it will be. Most of the projectors come with VGA cable, composite video cable, S-Video cable and M1-A connection. Newer projector models also have DVI inputs, Ethernet and USB ports.

Extra Features

In order to lure customers, most of the projector brands are coming up with projectors with many extra features such as built-in speakers, direct digital video input and a remote control. You should also check different projectors for advanced features available with them.

Keeping above points in mind, will be helpful in choosing the right projector at the right price for your different requirements.

Pros And Cons For Wireless Speakers

Before installing or buying, we must be aware of the pros and cons for wireless speakers. Most of us do not bother to do even a little research before deciding on a choice. This research in the beginning would reduce a lot of problems later. The wireless speakers come in different varieties categorized by specific features for specific usage. Now, for example a computer wireless speaker model should follow the desktop format, while a wall wireless speaker model must follow the wall mount format. Therefore, it is important to know the different types of wireless speakers and their advantages before you chose to buy one.

The pros first – These speakers can be used for a wide range of purposes. As they work on the principle of wireless connectivity, do not need any wired connection, and can be placed or installed anywhere, in the living room, bathroom, kitchen, garden and guest areas. You need not to worry about the walls as the sound frequencies can get transmitted through the walls. They come with remote controls for adjusting the bass, treble, volume, switching on special presets. The sound clarity is high, therefore people need not strain their ears, in order to listen to the music.

Most of the speakers are extremely durable, resistant to all types of weather, like snow, rain, heat, and humidity and it is also waterproof. Some special types of wireless speakers are built for specific purposes, therefore these models are built ergonomically for the ease of installation.
The wireless speakers have few cons as well – Such as, the distance between the player and the speakers must not be too much. If it goes beyond the range and the speakers would not receive any signals. There are long-range ones available in the market but that may exceed your budget. The wireless connectivity through infrared requires a clear line of sight, therefore it would not go through walls. Another mode of connectivity is the radio waves, which can go through the walls. But there is still a problem, these radio waves, being electromagnetic waves, get distorted by other electromagnetic waves. As a result the sound can get hampered.

Some time the durability can be a problem. Due to the heavy protection, the sound gets muffled. These speakers do not have any external power supply, so they need a power back up unit of their own, such as a rechargeable battery pack. There are battery power units fitted into the speakers, but they are more expensive than the ordinary ones.

Therefore before making a decision think about both the pros and cons of wireless speakers and choose one according to your requirements.

Incorporating Technology into Classroom Instruction for Revolutionized Learning

Multimedia is a technology that has taken business, industry, and education alike by storm. The proliferation of educational and training materials, incorporation of digitized sound, speech, images, and full motion video, with high speed computers and videodisc players that break the paradigm of linear, teacher-driven instruction promises to revolutionize the way we learn.

The effective application of this technology in education and training assists the audience in retaining most of the information they hear, what they see, and what they interact with. In multimedia presentation, learning occurs faster than with classroom instruction, and course content is mastered faster. Perhaps equally important is that when compared with classroom instruction, interactive multimedia learning also results in better training. Studies show that participants increase understanding, resulting in greater learning gains.

Computer technology provides a prominent and multifaceted tool that can transform the way educators teach and the way students learn. Consequently, there is an improved ability to search for abstract or complex material with increased student comprehension and interest. Instructors should thus consider the nature of technology and the potential range of its uses in higher education. One potential use of computer-enhanced instruction at the university level is to complement lecture courses in ways in which the computer-enhanced instruction program reviews, reinforces, or adds to materials presented in class. This is accomplished by integrating a variety of media sources such as words, graphs, sound and visuals. The result is an improved ability to present abstract or complex material with increased student comprehension and interest.

Research has shown that students usually learn more in classes in which they receive computer-based instruction and that they learn their lessons in less time with computer based instruction. Multimedia allow students to learn in their own style and at their own pace. An additional benefit is that CD-ROMs provide media and visually rich material that is more likely to correspond effectively with students’ individual learning styles.

Presentation programs offer college teachers the possibility of preparing educational materials that combine the visual as well as the auditory modes of learning. If the presented materials read clearly, the design incorporates a visual analogy, and the graphic presentation uses sound principles of emphasis and harmony, computer-enhanced instruction can dramatically portray new ideas.

Learning is a continuous process. However, the way instructors teach and students learn must be constantly reevaluated and updated. Teachers should be aware of the importance of using visuals to enhance information. Computer-enhanced instruction can be successful if faculty chooses to become leaders in the adoption of the use of technology to enhance lectures or presentations. The potential of technology is the ability of all students to learn at the highest levels with the greatest resources in order to have the promise of a future of real opportunity. Studies show significant links between multimedia instruction and achievement in traditional subject matter. Schools that integrate technology into the traditional curriculum have higher student attendance and lower drop out rates, which leads to better academic results.

It is believed that technology will continue to increase and become a standard part of the educational model. As this occurs, educators will have to put some of their traditional teaching techniques to the side to make room for multimedia. The old model of faculty lecture note taking has shown to be unsuccessful in making efficient use of faculty time for allocating information to large groups of learners or for learning by students with diverse backgrounds and skills.

However since students bring a wide variety of skills, backgrounds, interests, learning styles and motivations to the classroom, the challenge for teachers is to try to match the presentation material to such a diverse audience. Technology can address this problem in several ways. At a basic level, the variety of presentations provides a change of pace from a chalkboard or overhead projector. For example, a teacher could use technology to produce energetic animations, utilize computer models for complex systems, or to visualize three-dimensional data.

Another benefit of using various forms of multimedia is that complicated topics can be explained and understood better with the aid of pictures, graphs, animations and simulations. It also provides the option to present complex concepts in small, chronological steps as a means to improve students’ ability to comprehend information in a meaningful way. This concept is especially important for introductory classes that have students with assorted backgrounds and interests. Compared to the traditional presentation methods, multimedia has the capacity to offer instructors control over how and when information is presented to students.

Besides, a good number of universities have become captivated with multimedia instruction as a means to improve student satisfaction, performance and learning. Multimedia use in classes significantly motivates students by increasing student interest, involvement, enjoyment, and liking for the material covered in class.

The outcome of employing multimedia in teaching college students is a greater long-term retention compared to students taught by traditional classroom methods. It has also been observed that students taught with multimedia attend class more frequently and appear to be more interested than students taught without multimedia.

Consequently, multimedia will continue to grow at a rapid rate. Lectures that were once supplemented with chalkboards and transparencies can now be complemented with a large screen projection system that can handle the computer and the Internet.

Multimedia offers educators the opportunity to place their lectures onto the computer, along with new graphics and sound to create an engaging classroom presentation. This technology can lead to more active learning and adventurous teaching. By integrating technology sources into the classroom, courses can become more exciting and stimulating and possibly meet the needs of students with different learning styles.

Multimedia instruction increases learning content and retention, and reduces the amount of time it takes to learn material. Thus, traditional instructional and educational media must move to incorporate the concepts of multimedia. However, in order to maximize the potential of this technology, educators would have to be trained in the use of the most recent technology. This implies education not only in the available technology, but also the concepts governing effective production and usage, with a comprehensive curriculum providing both. This would thus facilitate teaching and learning for lecturers and students in educational institutions.

Comparing Wired and Wireless Speakers For Home Stereo Systems

Are you wondering as to the differences between home stereo wireless speakers and the wired variety? It’s easy to see why more and more people want to purchase wireless speakers once you run down the advantages and disadvantages of wireless speakers as opposed to wired ones. You can get more out of wireless speakers than just being freed of the burden involved with running and hooking up wire after wire.

Home stereo wireless speakers connect the speakers to the receiver through radio frequency, through which the sound is transmitted. A lot of consumers look to wireless speakers first and foremost because of its non-wired configuration.

Those of you who have prior experience are aware of the difficulty involved with hooking up wired speakers – all of the wires that have to be checked to see if they’re long enough, attaching each wire to the receiver and figuring out which end can go where. An entire day can be dedicated to this project, which can be very frustrating and aggravating. Wireless speakers can save you a lot of time, as you just need to set them where you need.

You can change the frequency of the speaker signal with knobs that are attacked to your home stereo wireless speakers. All too often, typical speakers intercept phone transmissions on the frequencies that you’re using, leaving you no choice but to keep moving the speakers around until you get to a point where you don’t hear the noise anymore, often having to do this several times. Wireless speakers don’t have this issue; a simple frequency change can fix whatever problem you come across of that nature.

Because you don’t have to worry about wire length anymore, home stereo wireless speaker placement is as easy as possible. There’s no need to drag wires across the room in order to put speakers at opposite ends of the room.

You don’t have to conceal wires as well, since there are no wires to speak of. No tape or throw rugs are needed to lay over the wires in order to hide them. With wireless speakers, you’ll be able to place your speakers wherever you want, and your room will still be free of clutter. Your sound system will look better than ever, thanks to the wireless presentation that eliminates tangles and knots.

How to Record Guitar at Home Using Indirect Recording

Indirect recording is what I would call the “old school” method of actually plugging into a real guitar amplifier, and using a microphone to record the sound. Minimally this method requires an amplifier, one or two microphones, mic-preamp and a converter. However, a whole heap of other units can be added, for example eq’s, mixers, compressors etc.

Before we get too technical, let’s first talk about the signal path. The signal path is the path that the audio takes from the microphone to get into the computer, and what happens along the way. For example – a simple signal path beginning at your microphone and ending at your computer workstation may include the following units along the way.

Below is a very basic signal chain showing how the signal travels from your guitar to your computer via various units.

Guitar > Amp > Mic > Mic Pre-Amp > EQ > Compressor > Converter > Computer

This illustration shows that once your guitar is amped, the sound will be picked up by a microphone, then sent to the mic pre-amp, which will boost the signal, and make it loud enough to actually use. From there the sound source could be send to some sort of eq unit, and a compressor to alter the levels. Finally the signal is sent to the convertor which will allow the music to reach your computer. Now, if I’ve lost you already, fear not!

Let’s take a quick look at what these different units do and how they work.

Microphone – When it comes to recording guitar at home, the microphone you choose can have a huge impact on the overall sound of your recording. A microphone is a device made to capture waves in air, water or hard material and translate them to an electrical signal. The most common method is via a thin membrane producing some proportional electrical signal.

Most microphones in use today for audio use electromagnetic generation (dynamic microphones) capacitance change (condenser microphones) or piezoelectric generation to produce the signal from mechanical vibration.

There are a lot of things to consider when it comes to the sound you get from your microphone, not only in terms of price and quality, but also where you actually place the mic in relation to your amplifier. Whilst the chances of getting a great recording are consistently better with a high quality microphone, price and quality do not always match.

Mic-Preamps – The signal that a microphone picks up is actually very low, and needs to be boosted for it to be used with your recording device. This is exactly what a mic-preamp does. It boosts the signal to a level that is useable for recording.

You may already have a mic preamp on your computer; however this is only designed for speech and is unfortunately unsuitable for any serious recording

Compressors – A compressor is a device that reduces (compresses) the dynamic range in a sound sources softest point to its loudest point to smooth the output, and can bring your audio material up to spec with professional recordings.

An instrument that goes from very quiet and very loud over the course of a song can be difficult to record and mix. Either the quiet parts get lost or the loud sections overload the recording.

Converters – In very basic terms the converter is the equipment that takes your analog audio from your compressor, eq unit, mic-preamp etc, and creates a digital representation, which is sent to, and is now useable with your computer.

Keep in mind that this is one of the most important units in your signal chain and it’s well worth spending a little more money to get a high quality converter.

Hopefully this has given you a little insight into the basics of recording, allowing you to see what equipment you will need and what each piece of kit does.

Prevent hacking webcam and mic


Recording devices like webcams and microphones become standard devices in every modern laptop. These devices can be hacked easily by potential intruders or being under attack of remote tapping. A simple worm that installed on the laptop can operate the webcam and microphone remotely and send the audio and video information to remote operator. Hacking these devices are not just a privacy issue, they can expose companies and organizations to industrial and military espionage.

The standard prevention tools like firewall, anti-virus and anti-malware are not providing sufficient solution. These tools are dealing with well known worms signatures. However, portable laptop can be infected by worms that using standard interface like java-script or while using unsecure public connections. The only safe solution to deal with webcam and microphone worms is to disconnect them completely. This can be done either permanently by cutting the microphone wires or blocking the webcam lens or temporarily by disabling these devices in sensitive places by the operating system. The temporary solution will give the laptop user the option to use audio and video in public places and block them in secure places like the company or organization campus.

Lan-Secure Wireless Protector: Cam and Mic Auto Disable has the perfect solution to deal with webcam and microphone hacking. The software will automatically disable webcams and microphones on computers that connected to the company network with LAN cable and re-enable them when the LAN cable is disconnected from the computer.

How does it work?
Lan-Secure software is installed on windows organization platform and all the laptops and protected computers needs to be added to the software protection list. The software will scan all protected computers either automatically or manually and deploy a protection service on the selected computers. The protection service will constantly monitor the LAN cable status and disable the webcams and microphones of the protected computers when the LAN of the organization is connected. Trying to enable these devices while the organization LAN is active will disable them again instantly. Only when the organization LAN cable will be disconnected from the protected computer, the protected devices will automatically re-enabled.

How does it protect the organization?
Organization computers can be victims of tapping attacks by webcams and microphones worms. These attacks can be used by potential intruders to collect audio and video information from selected organization employees. Disabling these devices on computers that connected to the organization LAN will prevent any installed worms from collecting audio and video information from the affected computers. Using software protection tool will prevent tapping from organization employees through their personal computers on the organization campus, where most sensitive information can be accessed and recorded for industrial and military espionage.

Computers recording devices like webcams and microphones are standard devices in modern laptops. However, these devices can be easily hacked by simple computer worms. Using software protection tool will prevent organization users from being exposed to industrial and military espionage in the organization campus and give them the ability to use those devices outside the organization.

Medicine of the Future: The Incredible Developments in Medical Technology

We have entered the second decade of the twenty-first century. Today, affordable smart phones are widespread, computer game graphics look almost life-like, computer animation is almost indistinguishable from actual footage, remote-controlled drones patrol the skies, and Google maps provide street views of practically any city on Earth. What’s more, every year, the storage capacity of the average computer hard drive increases along with the computing power. We are living on the threshold of what could be a highly advanced future.

Along with the computer technology, medical technology is also advancing rapidly. Micro-computers, bionic limbs, artificial organs, nanotechnology, and lab-grown organs can potentially improve the quality of human life and change modern medicine. Such changes may take some time to be fully realized, but they are in their infancy today.

Micro-Computers and Nanotechnology

Micro-computers are a fascinating concept, and, until fairly recent years, they were only just a concept. But, today, the concept has become a reality. The phrase “worth your weight in salt” does not apply to micro-computers. One such computer that has actually been manufactured is smaller than a grain of salt (4). Professors Dennis Sylvester and David Blaauw, from the University of Michigan, have created a tiny, millimeter-long computer that contains a battery, a central processing unit (CPU), sensors, a tiny radio emitter, and electronics for powering the chip (4). The tiny computer is powered by light, requiring 10 hours of indoor lighting or 1.5 hours of sunlight exposure (4). The device is designed for being inserted into the eyeballs of glaucoma victims. It collects data with sensors and transmits the data through a radio wave (4). If there is too much internal pressure, the chip will transmit the data to medical professionals who will know what to do with the patient. Regarding this incredible technology, Sylvester said, “This is the first true millimeter-scale complete computing system. Our work is unique in the sense that we’re thinking about complete systems in which all the components are low-power and fit on the chip. We can collect data, store it and transmit it. The applications for systems of this size are endless” (5).

DNA-Computer.jpgAnother kind of micro-computer is in the process of being developed. Unlike Sylvester and Blaauw’s micro-computer, this one would use DNA for its electrical components. At the Hebrew University of Jerusalem a team of scientists has created the first DNA logic gates (3). Like their non-biological counterparts, the DNA logic gates represent one of two possible states, such as the zeros or ones of binary code (3). When one of two inputs was present at a DNA logic gate, the gate fluoresced, giving off light. And, when both of the two inputs or neither were present, the gate ceased fluorescing. This is similar to how a computer logic gate works. The DNA logic gates, when connected together and injected under the skin, may be able to form a biological-based computing system that can detect, diagnose, and treat common sicknesses or medical conditions (3).

gold-nanotech-2.jpgSpeaking of computers, a fairly new technology field has been gaining ground in recent years. Ever since Don Eigler of IBM spelled out “IBM” with 35 individual xenon atoms in 1989 (13), nanotechnology has been making many breakthroughs. Unlike most technology, which is easily visible to the unaided eye, nanotechnology deals with components much smaller than the head of a pin. Instead of being measured in meters, these components are measured in nanometers. To get a picture of how small this is, a billion nanometers can fit in one meter. Some examples of nanotechnology already in use would include carbon nanotubes (made out of billions of individual carbon atoms). These are currently being used to give extra strength to mountain bikes, golf club, and other high-end sporting equipment (7). Because they are composed entirely of carbon atoms, carbon nanotubes are used in water purification systems. Carbon, which is found in filters and diamonds, is good at attracting impurities and has a strong bonding arrangement.

Nanotechnology also has great promise for the future of medicine. One application of nanotechnology to the medical field is through the use of nanobots–microscopic machines made out of molecules–for fighting infection. Researchers at the Southwest UK Paediatric Burns Centre at Frenchay Hospital in Bristol have teamed up with scientists at the University of Bath to develop a “dressing” that kills pathogens (such as bacteria) by releasing antibiotics from “nanocapsules” (12). The harmful bacteria produce toxins which eat through the “nanocapsules”, releasing antibiotics (12). If this is perfected, the way doctors treat diseases may change. A patient may find that all he or she needs to do to recover from an illness is to simply swallow a pill: a pill filled with “nanocapsules”. Some other possibilities for nanotechnology in medicine might include nanobots for repairing damaged cells, nanobots for accelerating bone repair, and nanobots for killing cancer cells (14). Yes, you read it correctly, nanotechnology is thought to be a possible cure for cancer.


iLimb2.gifNanotechnology also has another application in the developing area of medical technology called bionics. Imagine that you lose both your hands. Now, you are unable to work or do a lot of the things you enjoy. But, there is no need to worry. All you have to do is purchase an i-LIMB and have it installed. It sounds like it could be something made by Apple along the same lines of an iphone or ipod, but the i-LIMB is not another phone or portable computer. It is a prosthetic, robotic hand, created by Touch Bionics, that allows users to pick up a variety of objects, including glasses, playing cards, and suitcases. It works by detecting tiny electrical signals from arm muscles to control the movements of its individual, robotic fingers, wrist, and thumb (11). Bionic legs that work in a similar way to the i-LIMB are also on the market.

Besides prosthetic limbs, bionic technology offers replacement hearts, lungs, eyes, ears, and the potential for much more. Since we don’t have time to delve into all these unique and cutting-edge technologies, let’s take a look at the bionic eye. The Argus II, an amazing device created by Second Sight, a California-based company, allows the blind to see once again, albeit with lircjRetina.gifmited vision. According to Robert Greenberg, president and CEO of Second Sight, “Patients can locate and recognize simple objects, see people in front of them, and follow their movement. They can find doors and windows, follow lines, and in the best cases read large print slowly” (6). This limited amount of sight comes with a cost: 115,000 U.S. dollars (6). It makes use of an array of electrical photoreceptors that stimulate retinal cells at the back of the eye, which then send a signal through the optic nerves to the brain. A wireless signal is transmitted from a camera built into a pair of glasses, worn by the patient, to a chip implanted near the retina (6). Besides having limited seeing capabilities, the Argus II only works for people who have a rare disease called retinitis pigmentosa, which only damages light-sensing photoreceptors and leaves the other retinal cells alone (6). The Argus II is currently only available in a number of clinics in the U.K., France, and Switzerland (6). If you live in the United States and you have retinitis pigmentosa, you’ll have to hop on a plane and have over 115,000 dollars at your disposal. For most, this is far too costly. Perhaps, as the technology is refined, it will become cheaper and more available to the general public.

Pretend that you had a healthy eye, but your optic nerve was damaged. Is there any way to repair the damaged nerve? We have looked at bionic hands and mentioned bionic legs, but is there such thing as a bionic nerve? Surprisingly, the answer is “yes”. Scientists at the University of Manchester have converted adult fat-tissue stem cells from animals into nerve cells (2). Their goal is to make an artificial nerve to replace damaged nerves or nerve sections. Soon, they will be collecting adult stem cells and will try to convert them into nerve cells. They plan to make a “bionic” nerve by inserting the converted stem cells into a biodegradable polymer tube, which they will then surgically place into a break in a nerve (2). The growing nerve fiber will be able to pass through the tube and connect with the other end of the nerve, repairing the break (2). This “bionic” nerve could replace broken nerves in patients with cancer, in patients who have had tumor surgery, and in patients who have had severe injuries to their limbs (2).

Regenerative Medicine

fingerDM1705_468x315.jpgRe-growing nerve cells is one thing, but re-growing a finger or a limb is another thing entirely. The technology for re-growing fingers and limbs seems like it would belong in a science-fiction novel. But scientists today think that such science-fiction-like ideas are possible with a new type of medicine called regenerative medicine. Though regenerative medicine is currently in its developmental stage, a few amazing breakthroughs have been made. In 2005, a Cincinnati hobby-store owner, Lee Spievack, cut off his finger tip when showing a customer a model airplane (1). His brother, Alan Spievack, who is a medical research scientist, gave him a special powder to sprinkle on his finger. After taking the powder, Lee Spievack was astonished to find that his fingertip was growing back. Four weeks later, it looked as good as new (1). The powder he took was made from a substance called extracellular matrix. It was developed by scientists at the University of Pittsburgh’s McGowan Institute of Regenerative Medicine (1). The extracellular matrix powder is made from pig bladders (1), but it does not contain in pig cells (9). Instead, the matrix is composed of proteins, such as collagen (9), and connective tissue, which scientists believe stimulates the regeneration of tissue (1). The function of the extracellular matrix is to form a structure that helps cells generate any given body part (9). All animals have this special structure, as do developing babies (or fetuses). Two-year-olds have even been documented to re-grow missing finger tips with no medical help (9). This amazing framework for cell regeneration has many possibilities for the future of medicine. Some believe that the human body may be able to re-grow entire limbs due to the extracellular matrix. If that were possible, bionic prosthetics may be unnecessary.

FE_DA_BH_Pioneers_Atala.jpgRegenerative medicine is not limited to special powders for regeneration. Dr. Anthony Atala of Wake Forest University has grown muscle tissue, heart tissue, and a total of 18 different types of tissue in his laboratory (1). He’s even grown a mouse heart (1). Atala is quoted in a New York Times article as saying, “A salamander can grow back its leg. Why can’t a human do the same?” (10). One idea Atala has for replacing damaged organs is to surgically insert a biodegradable scaffolding, containing regenerative cells, into the body (10). The cells will theoretically grow to form the replacement organ and the scaffolding will eventually decompose. If this actually works, replacement organs will no longer need to be taken from organ donors when they’ve died (10). Perhaps, in the future, people could extend their lives by replacing their organs and damaged tissues with lab-grown counterparts, but right now that technology is still experimental.

Extending and improving the quality of life is the whole purpose of modern medicine. This article focused on some of the technologies being developed in three areas of modern medicine. We looked at the role played by micro-computers and nanotechnology and how nanobots could theoretically stop infections. In the area of bionics, we briefly examined some of the bionic technologies scientists are working on, such as the bionic hand. In the last section, we saw how regenerative medicine has allowed people 6a00d83451c79e69e2015391fbad99970b-500wito grow back their finger tips. Finally, we learned that organs and cell tissues are being grown in laboratories with the goal that they will be used to replace or repair natural organs. There seems to be a pattern in the goals set for the future of medicine technology. Scientists, technologists, and thinkers have envisioned a future where medical technology will provide people with a vehicle to live forever. Aubrey de Grey, a biomedical gerontologist believes that sometime in the future, the process of aging will be stopped. He told a Reuters correspondent that there is “a 50/50 chance of bringing aging under…a decisive level of medical control within the next 25 years or so” (8). He added, “And what I mean by decisive is the same sort of medical control that we have over most infectious diseases today” (8). If this prediction is true, we may find ourselves in a very different world from the one we know. Living for an eternity sounds wonderful, but, on our decaying planet, would it really be such a good thing? Aside from the good reasons for the development of medical technology, does it seem at all like some people may be trying to play God? I leave that thought for you to ponder.

Health risk of wireless speakers/headphones

Nowadays there are a lot of thing people tend to say is a health risk for us. After the wireless speakers/headphones was created the people started doing research on wireless headphones and came to the conclusion that it is dangerous for you to use, some even claimed that it can cause cancer tumors.

These wireless speakers/headphones are comparing to the mobile phone because both sends and receives signals and that both are held against you head/ears. Do not believe this because wireless headphones can not cause cancer and wireless headphones are not a threat to your health.

There are a lot of different products that also receive the equal amount of uv/rays such as the radio signals and the transmitters in the TV’s which have been used for 60 years so far.

If you should compare the total deaths on exposure to solar radiation and the amount of motor car deaths you cannot even compare it so big is the difference, have you ever heard of someone who died when they pumped up the volume or changed the station.
Until today there is no proof that radio signals can cause death or submit any terminal illnesses.

The only health risk of wireless speakers/headphones is by buying yourself noise canceling wireless speakers/headphones and if you turn the volume so loud that you cannot hear anything around you accept for the music you are listening to.

So for a final conclusion is that wireless speakers/headphones are Not a health risk for you, a lot of people are scared of the new technology, but more people will die of car accidents than of a radio, infrared or Bluetooth signal.

If you are looking to find more wireless speakers/headphones, different products, surround sound information and where to buy some please visit the following sites.

What Is Structured Cabling For Computer LAN Networks?

:: What is structured cabling?

Modern computer LAN (local area network) wiring has the concept of structured cabling.

With today’s high speed networks, people realize that the networking system must be broken up into shorter chunks that allow workstation wiring to be concentrated, with each cable length short enough to support the high data rate.

Based on aforementioned reasons, structured wiring standard has been developed to help define a computer wiring system that stays within the maximum wiring distance for various LAN topologies. For example, the horizontal cable wiring length is 100 meters for 100BaseT networks.

:: What do we do to observe the 100 meters wiring standard?

In order to achieve the wiring concentration standard, telecommunication rooms (wiring centers) are placed at planned locations in a building. These telecom rooms are then interconnected to provide the total network connectivity for the building.

This can be explained in a three stories building. At one same corner of each floor, a telecom rooms is constructed; these telecom rooms are then connected by backbone wiring (cables run vertically through the floors and link all telecom rooms together).

On each floor, a telecom room concentrates all workstation cables for that floor. Each workstation has a wall mounted jack. The network cable is terminated at that jack and runs directly to the telecom room. The cable may run in wire trays or conduit, or be draped over supports such as a drop ceiling. For larger floors, more than one telecom room may be needed.

:: Horizontal Cabling

The horizontal wires, which run from workstations on the same floor to the telecom room, are then terminated on punchdown termination, or directly onto a patch panel. The punchdown terminations or patch panels could be rack mounted (19″ or 23″ racks), cabinet mounted or wall mounted.

In the telecom room, network equipment such as a hub or switch is connected to each station cable, which electrically terminates the cable run. The hub or switch then passes the computer signal on to other work stations or servers, or even to other telecom rooms for ultimate connectivity with the entire network.

:: Vertical Cabling (Backbone Cabling)

Telecom rooms on each floor are then connected together by backbone cabling (also called vertical cabling for floor to floor connections). These backbone cablings typically are done from floor to floor to floor.

Usually telecom rooms should be located directly above one another in order to minimize the cable runs length, but this also varies from building to building.

With the emerge of Gigabit Ethernet and 10 Gigabit Ethernet, fiber optic cable is the most appropriate choice for backbone cabling since they provide much higher bandwidth than traditional Cat5, Cat6 or even Cat7 twisted pair copper cables. Another advantage of fiber is that fibers can run much longer distance than copper cable, which makes them especially attractive for backbone cabling.

:: The difference between backbone cabling and horizontal cabling

Since backbone cabling typically passes through from floor to floor, the cables used for backbone cabling have very different requirement than the horizontal cablings.

1. Fire ratings. Backbone cables must have standard imposed fire rating specifications. Typically this is OFNR (Optical Fiber Non-Conductive Riser) rated. If the backbone cable passes through plenum area (spaces in the building used for air return in air conditioning), the cable must be OFNP (Optical Fiber Non-conductive Plenum) rated.

2. Physical securing. Physical securing for vertical riser cables is also different than horizontal cables. So is the cable strength, since vertical riser cables need to have enough strength to support its own weight.

The Importance of Computer Technology in Setting Up a Project Management System

In the world of globalization, Information system is such where data are collected, classified and put into process interpreting the result thereon in order to provide an integrated series of information for further communicating and analyzing. In a progressively more spirited worldwide atmosphere, Information System plays the role as ‘enabler and facilitator’, which endows with tactical values to the officialdom and considerable step up to the excellence of administration. ‘An Information System is a particular type of work system that uses information technology to detain, put on the air, store, retrieve, manipulate or display information, thereby partisan one or more other work structure’. In totting up to taking sides assessment making, co-ordination and control, information systems may also help managers and workers investigate problems, envisage complex subjects and generate new merchandise or services.

The criteria of operational  systems and the idata management  systems that support analytically pass through at least four phases: a) Introducing the system  of manipulating the need to promulgate  on going operational Management  system b) development of  the process of acquiring and configuring/installing the necessary hardware, software and other resources c) implementation, the process of making new system operational in the organisation, and d) Operation and maintenance, the process concerned with the operation of the system, correcting any problems that may arise and ensuring that the system is delivering the anticipating benefits. The management of these processes can be achieved and controlled using a series of techniques and management tools which, collectively, tend to be known as Structured Management System. Two important methodologies:  PRINCE (Projects IN a Controlled Environment), and SSADM (Structured Systems Analysis and Design Methodology),structured by the Central Computing and Telecommunications Agency (CCTA), are used widely in the UK public sector and in some Developing Countries, like Bangladesh, Pakistan, Nepal etc. Prior to comment on the application of these methods in the Developing Countries, it would be pertinent to describe brief outlines of these methodologies.

It is a significant fact that PRINCE is a project management method; not system development, which covers the organisation, management and control of projects. Since its introduction in 1989, PRINCE has become widely used in both the public and private sectors and is now the UK’s de facto standard for project management. Although PRINCE was originally developed for the needs of IT projects, the method has also been used on many non-IT projects. PRINCE requires a dedicated team to be established to manage and carry out each project. It therefore aims to provide a supporting framework between the current state of affairs and the planned future state. PRINCE focuses attention on end-products rather than activities, ensuring that the organisation actually gets what it wants out of the project. Quality is seen as a necessary and integral part of the project and the focus on end-products enables the criteria by which quality is to be judged to be specified at the outset of the project. It requires the development of a viable “business case” for the project at its outset and that the business case needs to be periodically reviewed.

In PRINCE a project is regarded as having the following characteristics:

 defined and unique set of technical products to meet the business needs
 corresponding set of activities to construct those products
 certain amount of resources
 finite lifespan
 organisational structure with defined responsibilities

In such Management Structured System, an approach to planning based on products rather than activities and the use of this approach for the benefits. It also emphasises that projects needs to define the ‘ shape’ or manageable phases of a project to promote sound business control. Stages are characterised by the production of specific products. The PRINCE model for projects is based on two main principles:

The project is a joint responsibility between users, the developers and the organisation for whose benefit the end-product is being developed
In order for projects to succeed, a special structure is demanded to manage the project throughout its life – from conception through build to handover. This structure is distinct from normal line management.

By Using these principles, the model defines three levels of activity:
Overall project management and major decision making
Day-to-day management
Production of end-products

These three levels of activity are assigned respectively to the Project Board, to the Project and Stage Managers, and to the Technical Teams. The latest version of the method, PRINCE 2, is a process-based approach for project management providing an easily tailored, and scaleable method for the management of all types of projects. Each process is defined with its key inputs and outputs together with the specific objectives to be achieved and activities to be carried out. In the following diagram, the process-based approach is shown:
Structured Management  Process Model
Such Standard Method  provides benefits to the organisation, as well as the managers and directors of the project, through the controllable use of resources and the ability to manage business and project risk more effectively. PRINCE enables projects to have:

 a controlled and organised start, middle and end;
 regular reviews of progress against plan and against Business Case;
 flexible decision points;
 automatic management control of any deviations from the plan;
 the involvement of management and stakeholders at the right time and place during the project;
 good communication channels between the project, project management, and the rest of the organisation.

There is no denying the fact that SSADM is a highly structured and rigorous method of systems development ,was originally developed by Learmonth and Burchett Management System (LBMS) following an investigation by the CCTA into adopting a standard Information System (IS) development method for use in UK government projects. It was launched in 1981 and by 1983 became mandatory for all the government IS developments. This gave SSADM a large toehold in the IS structured methods market.
It is a prerequisite for SSADM that user commitment and involvement are agreed right from the start. It provides a top-down approach, where a high level picture is drawn up and subsequently refined into lower levels of detail. One extremely important concept in SSADM is the distinction between logical and physical views of system components.

The following purpose are generally fulfilled by such important methods.

 Provide a sound platform for communications between analysts, designers and users;
 Reduce errors and gaps in the specification produced
 Improve the quality of software documentation and the productivity of analysts;
 Reduce potential risks by presenting analysts with a structural framework for the use of techniques, and a standard for documentation end-products;
 Provide techniques for checking completeness and accuracy;
 Improve the maintainability of the new systems;
 Reuse staff and skills on other projects;
 Protect investment in analysis and design, and to allow freedom in implementation techniques.
SSADM consists of three main components:

 The structure or framework of an SSADM project
 A set of standard analysis and design techniques
 The products of each technique
The structure of SSADM might appear a little complex at first, but will make more sense as we began to look at the method in more detail. Following diagram illustrates the breakdown of the life cycle into a hierarchy of modules, stages, steps and tasks.Each module represents a SSADM phase, and is made up of one or two stages. Where a module contains two stages, one will be an analysis or design and the other will be a project decision stage. Each stages is made up of between two to seven steps, which provide the framework for applying and controlling the development techniques. The tasks to be carried out within each step define how the techniques should be used, and specify the required standard of the products output from the step. Following diagram shows the breakdown of SSADM’s modules and stages.The major analysis techniques mainly used are as follows:

 Business Activity Modelling (BAM) – explicitly describes what goes on that part of the business under investigation. The activities are defined from purely a business rather than on IS perspective. Recommended approach to be used in the construction of a BAM may be Soft System Methodology (SSM), Functional Decomposition or Resource Flow Diagrams.
 Logical Data Modelling (LDM), representing system data, is applied throughout the life cycle to provide the foundation of the new system;
 Work Practice Model (WPM) maps business activities onto the organisation structure defining user roles to the underlying business activities.

The key important thing is the end-product. Each step has number of tasks associated with it, most of which lead to the creation or enhancement of standard SSADM products. At the end of an SSADM project the new system will be described by the sum of these products. Products can be divided into three basic groups: Processing, Data and System-User (or Human-Computer) Interface.

By way of substantiating the Information System in developing countries is a complicated virtual process, specially in the public sector. With the growing needs in the information age, and by the pressure from the international donors , big and ambitious projects has been undertaken by the public sector in developing countries . But due to the lack of standard procedures and methodologies for IS development caused many projects to combat problems in the implementation stage. Many projects failed to attain their business needs, as they were too large and highly ambitious. Basic reasons for the project failure in the developing countries can be characterised as the following:

 Solving wrong problem;
 Technology led, not business;
 Lack of major stakeholder involvement;
 Experts lead, rather than facilitate;
 Lack of commitment and hidden agenda;
 Benefits not identified and quantified at outset.

Nowadays, the developing countries are applying both PRINCE AND SSADM methodologies, the project management development techniques, specially designed for IT projects, that are funded by the UK Department for International development (DFID).

4.2 In Bangladesh , private sectors are advancing with IS development , but it is not the identical situation in the public sector. The reasons behind this may be the poor salary structure in the public service, which never give confidence to the prospective talents and system designers to join the public services. Most of the IT projects are donor funded; domestically financed IT projects rarely experience success like the donor projects.

4.3 However, RIBEC (Reforms in Budgeting and Expenditure Control) project, funded by DFID, has been considered as the most successful project in Bangladesh.

At the early stage of RIBEC project (Phase 2), it was observed that, the project was design to develop and modernise the budgeting and accounting system of the government of Bangladesh. The experts mainly dominated that phase, including lots of things to cover. There was lack of stakeholders’ involvement; problems were not recognised at the initial stage. Only a range of high-grade staff in the relevant field was given a general IT training. There was no follow up; no visible product was seen. Benefits were not identified. No system was developed to automate the budgeting and accounting system. So this phase 2 had experienced a massive failure. Having awful experience, the following phase (2A and 2B), a downsized project with specific output targets came up with analysing user requirements. This phase focused on sustainability and proved successful with sustainable solutions especially in the software development for budgeting and accounting Substantive training had been offered to the users of the systems. Stakeholders have been involved in the software development process and the local vendors who will be easily available in the future, developed the systems. Following PRINCE and SSADM as methods for project management and system development, RIBEC project is now considered as a model for other projects which implies the potential scope for applying these methodologies.Financial Management Project for HMG Nepal has been designed to establish a reliable database to ensure user friendly and reliable financial information and to computerise budgetary system. CCTA guidelines for IS strategy including PRINCE and SSADM were followed in developing the system.  In Pakistan, Lahore WASA project experienced badly as the original proposal was too big and not phased project; no analysis of business needs, solution was technology led, benefits were not identified at outset, high risk strategy, questionable long-term sustainability, lack of training facilities and computing skill within organisation etc. So, 2 years’ costs and effort were wasted.

By taking into consideration the UK approach of project management, Lahore WASA claim to be successor and benefits are realised especially in the billing from bimonthly billing to daily billing and reduction in bill production cycle. The main project management approach in the new proposal includes: redefinition of purpose, identify business benefits, prioritise outputs, involvement of stakeholders, DIFID played the role as the facilitator not doer, ownership of solution by stakeholders, use of local consultant etc, phased development, distributed system.

In view of the above it is evident that ‘Information technology and Information systems for what they really are – powerful and valuable tools, but not magic. When applied thoughtfully, these tools can bring important benefits for individuals, organisations, and customers. When misapplied, they can waste tremendous amounts of time, effort, and money’.The USA, a Progressed and well structured country that is economically and technologically advanced, designed PRINCE AND SSADM, to meet their own requirements. It cannot be expected that these structured methodologies would equally suit the resource scarce developing countries. But the above discussions surmise that there is potential scope and rationale for applying PRINCE AND SSADM that would facilitate the developing countries for better project management and system development. But again, these methodologies need not be considered as the “ final conclusive critics”, rather these structural criteria should be used thoughtfully, tailored to manage projects efficiently and to develop effective information systems to cope with the challenge of change Management virtually.

Information Technology Jobs and What They Require

There are many Information Technology (better known as IT) jobs around the world. There are small IT companies and big IT companies that all have an important role with many companies. There are various jobs that include an IT position, and they range from computer support to a computer administrator. Each position is extremely important because when you think of an office position, many computers are involved. Information technology positions are able to assist with the functions of a computer and keep them running smoothly. They handle various programs to analyze and support the company.

Denver IT jobs are extremely important because when an office is trying to function properly and a computer goes out, many people do not know how to fix this issue. An IT worker can help to update software, fix an issue or simply show others how to use certain programs that are difficult to handle. Often times, a company has a great amount of information stored on their hard drive or in another program to keep confidentiality and security. If an issue arises with this program, a company could potentially lose a lot of data and information. IT specialists can help to restore this information and make it so that there are no issues of loss in the future.

It is important in this day and age to ensure that the information that is stored on your computer is backed up correctly and is secure for many years to come. Information Technology professionals can assist with this difficult process to maintain different network servers and keep all information where it should be. It may seem like a difficult thing to learn, and it is, but there are many professionals out there to assist you when needed. It is worth paying for and taking the time to learn because it is used in so many fields.

When hiring an IT professional, make sure they have the correct training and experience to handle your company’s business. Find someone who has a passion in the computer industry and who will ensure that your data is handled correctly. Do your research and find someone that is reliable and credible. It is helpful to ask your local friends and family members for recommendations when hiring a professional because they can give you their input on who is of great quality to hire.

It is important to hire a professional that can figure out all of the computer basics, work a help desk, speak publicly, and train others without a problem. There are many situations where these skills are needed and are important to know in all aspects of computer work. Many people are not educated in the field of computers or technology and that is why having these professionals that know what they are doing is crucial. Almost every company, big or small, is involved with IT and that is why hiring the right people who understand the importance of these things working properly is significant to that company’s success.

If you have any desire to work with programs, analytics, or software, IT would be a good field to look into. It is important to have a passion for what you are doing and to have the desire to help those who need your assistance. Many companies have multiple IT workers because each one of them specializes in a different field of IT and has expertise on each component that goes into the business. Denver IT jobs may be competitive and hard to find, but they are worth the difficult process.

Acer Aspire One D255 Netbook Reviews


Acer Aspire One D255 Netbook – Switch Between Windows and Android

With cut throat competition in the netbook segment, there is always pressure on leading brands to develop differentiated offerings. Acer’s D255 netbook is one of the first 10 inch screen laptops to be embedded with the new 1.5 GHz Intel Atom N550 processor.

The Acer D255 comes loaded with Windows 7 Starter & Android 2.1; although adequate for the Android environment, the 1 GB RAM is barely enough for the Windows 7 interface. The D255 has got a 250 GB hard drive which is reasonably spacious for a 10″inch netbook. The N550 processor takes care of most multi threaded applications and the Intel GMA 3150 graphics chipset makes the multimedia experience exciting.

acer d255 Acer Aspire One D255 Netbook Reviews


Connectivity is standard in the Aspire D255 with three benchmarks USB 2.0 ports, VGA video output, SDHC/MMC card reader plus headphone & microphone jacks. Wi-Fi and Bluetooth are provided as the basic wireless solutions, with a webcam and microphone integrated on the top of the screen.

The D255 has large keys with an intelligent layout with proper shortcuts. The best part though is the good key feedback and a similarly brilliant click in the keys. The only negative aspect of the D255’s keyboard is the lack of space for the palms. The touch pad is small but highly sensitive and merges itself into the palm rest area not appearing odd to the user.

The screen of the Aspire One D255 is less surprising. It has glossy coating leading to vibrant colors and a well lit LED to avoid reflections. The screen is, however, well designed, and the display is perfect from deviating angles.

The speakers are satisfactory but competent enough. The music listening experience is an exception though without any real bass or treble, but acceptable. For other multimedia like movies or online media the user will have to use headphones.

Although the Acer netbook boasts nothing extraordinary, it does, however, carry a very impressive design. There are multiple colors available for the top and palm rest area, while a majority of the net-book is black. Acer Aspire One D255 comes in red, black, white, blue and brown mixed with a black body.

Acer Aspire One D255 netbook Acer Aspire One D255 Netbook Reviews

The D255′s applications are limited however, with the 2.1 Android, which has limited choices for applications. Initially designed for touch screen devices and now stuck with a small net-book, the Android OS is no good for this machine. Windows 7 Starter is, however, a great but limited option. The 1 GB RAM is not enough to drive the Windows OS. With no notable improvements to the laptop battery life, there is a serious battery life issue when running Windows 7. The amazing prospect of the Android 2.1 OS is that the booting time is a mere 15 seconds.

All in all, the D255 has a good processor and the ability to switch easily between Windows & Android.  The lacking features are the battery life and chipset features, which should have had some radical upgrades. For a price of almost £200, the D255 might just tempt the odd one out, but this netbook will probably not make waves.

Office Conference Room Equipment – Checklist

Here is a checklist of must have conference room equipment for offices or small business.

  1. Projector: Projectors are the most needed equipment in conference rooms. They are needed to project all your presentations, slides and graphics on to a projection screen so everybody can see them. Select from overhead, stationary or portable projector.
  1. Projector Screens: As stated above, projection screens are needed so that everybody can see presentations, slides and graphics. Select from manual or electronic projector. Also keep in mind size of the room to know which screen size you’ll need.

Modern technology makes better life

Do you think modern technology has made life easier and safer? Or do you think that modern technology has made life more difficult and more dangerous?

Technology today has made life easier and quicker but dangerous. As we look at technologies, questions are risen. By the way what are technologies? Modern technology is machinery that makes life easier. For example, microwave ovens cook food easily without using stoves and making a big mess. And dishwashers put all dirty dishes into the dishwasher and it washes them. Dishwashers are very easy to use and save time comparing it in the old fashion way. Today modern technology also has created problems because they are dangerous.

How is technology dangerous? The answer to this question is very simple. There’s lots of incident where there is malfunction in technology. For example, if there is a problem with a car than the car won’t be able to run, or if there is a technical mistake in a train computer system than the train would probably dysfunction and this could lead to a crash. Many people dislike the production of technology. Technology also creates financial problems in families because most technologies are very expensive to buy like the computers, televisions, refrigerators, dvd, and home theatre systems. People who cannot afford to buy this kind of technology live a stressful life. They have to do everything the old fashioned way, which is time consuming. They have to wash their dishes by hand. And those who don’t have a computer have either go to a library which is time consuming or have to type a letter or report with a typewriter which is also time consuming since there is no spell check and if there is an error it is going to be difficult to correct.

There are more advantages intechnologiesthan disadvantages. How is technology an advantage? Today technology is very important in society because it makes life easier to live on and not time consuming.

There is no doubt that televisions and computers have made our lives much easier than before, as everything now is done in minutes via computer, and any sort or news or video is available to view via television. They have educated the world by showing educational programs. However, on the other hand, they have destroyed the whole world. Due to the attraction of television andcomputers most people will be found at the eye-doctor’s office or will be found wearing eyeglasses or lenses. Interviews with the doctors have clearly demonstrated that 90 percent of the people wearing glasses have damaged their eyes by watching television or sitting by the computer. We all have seen small children wearing eyeglasses. Are all these children born with weak eyesight? No, all of them are not; they are not born with weak eyesight. This happens because they gave extra time on these modern technologies – television and computers.

Document Cameras: Relief from Overhead Projectors

Document Cameras are nothing but the capturing devices to display an object or number of objects in front of audience. Document cameras are able to magnify the images of actual 3-D objects and transparencies. Document cameras were first developed to meet the rising demand for the ability to project and present original documents, objects directly without the usage of overhead projector. Document cameras are also known with different names and that are image presenters, visual presenters, digital visualizers, digital overheads and docucams. Document cameras are high resolution web cams which are to be mounted on arms so as to facilitate their placement over a page and all the objects can be displayed through it infact most of the objects are need to be placed under the camera only. Document cameras are the ones which take the picture and in turn produce a live picture via projector.

Now a days, Document cameras are replacing overhead projectors which were used earlier for the same very purpose. Due to having so many features like zoom a document camera can zero in on small print in books and can even project printed pages like transparencies. Document camera is an asset to classroom learning because it does not require room to be dark. The other key feature of document camera is that it can also send video signals to a computer via USB cable and at times it can even connected to an interactive whiteboard instead of a standard screen. Now most of the document cameras are to be provided with an accessory so that it can be used with a microscope.

Document camera is a combination of several different technologies. The quality of the recorded image is dependent on the primary components, which are optics, camera, lighting system and motherboard. Today Document cameras are available with HDMI output, Audio/Video recording and playback is also possible, and some of them are also using high-speed WIFI technology to eliminate the need to wires.

Document cameras are of different types but are broadly categorized into two groups and that are portable and desktop models, ceiling models. Portable and desktop models are nothing but very much similar to that of overhead projectors and it can be used in multiple locations without requiring any prior special installation whereas ceiling models or ceiling mounted document cameras are models which allow much larger objects to display. Ceiling models are basically used to support telepresence systems as it allows the illusion to be created.


Today, document cameras can be seen in almost each and every other classroom it is converting into a great classroom management tool. Its use brings an end to the days of children pushing and shoving to gain a better view of a teacher-demonstrated science experiment. Today teachers can use document camera to display a kitchen timer while the class is working. Document cameras are also an excellent tool for creating “green” school. The major uses of document cameras for classroom are demonstration that is to show the students that how to do the assigned work, Showing math examples, Immediate feedback for displaying student work, Close up detailed observation of objects, Zoom in on reading text and read whole class-helps when pointing out certain topics words and students can follow along, Use lined paper to project onto white board.

How to choose the best LCD and DLP Projectors for your school

Bookish knowledge is a thing of past. Students no longer want to be called ‘bookworms’ as they wish to gain practical knowledge with interactive resources for a lasting visual impact on their minds.

Like them, teachers and parents also started believing in the fact that interactive teaching resources are a need of the hour to impart ‘Quality’ education to children of today.

One such interactive teaching resource that can offer highly engaging and interactive experience to its users is a Projector.

As a user you can opt for good Projectors in order to make a good start. Before making an appropriate choice between LCD and DLP projectors for your classroom, you should keep few key differences in mind.

Firstly, LCD projectors operate by shining light through transparent LCD cells which use three separate color panels (red, green, and blue) to produce the desired color of the projected image. On the other hand, DLP projectors project image by reflecting lights against hundreds of tiny mirrors called digital micro devices.

Secondly, LCD projectors offer excellent color saturation and usually have adjustable contrast and brightness feature. Whereas, DLP projectors are usually lighter and much compact, connects easily with digital devices andhave high contrast ratio which makes them capable of projecting clear video images as compared to their LCD counterparts.

Lastly, LCD projectors have a wider connectivity range and are generally much brighter as compared to DLP Projectors at the similar lumen output.

These key differences between LCD and DLP projectors can help you to choose the best possible option to be installed in your classrooms for an extremely engaging teaching and learning experience full of audio-visual media including graphics, images, videos, and sounds.

The Importance of Technology In Business

A June 23, 2005 news release from the Office of Advocacy, U.S. Small Business Administration, states that home computer owners are slightly more likely to be business owners than non-computer owners. This report reveals that technology and computing has become an inseparable ingredient in the business world today.

The Computer Trend – A Brief History

The last two decades have marked an enormous increase in the number of home computers. With it, computer owners have invariably taken to entrepreneurship in many varied fields. Thanks to the growth of technology, computers and the Internet, new methods have been developed for processing everyday business activities easily. Without the advent of technology, routine tasks would otherwise have taken and enormous amount of time and specialization. Undoubtedly, the computer represents the top technology development in the last century as it relates to businesses today, both large and small. Advances in the field of technology have created a vast number of business opportunities.

Some Statistics

In 2003, the U.S. Small Business Administration produced a report/survey that established conclusively that more than 75% of small businesses owned computers and had heavily invested in new technology. Let us try to understand what the computers mean to businesses and how they contribute to increase their productivity.


The fundamental reasons for the popularity of computers with small businesses are their efficiency, speed, low procurement cost and more than anything else, capability to handle multiple tasks with little chance for error.

Office Routines: Almost invariably, businesses loaded with the burden of increasing workloads and the pressures of being lean and mean, fall back upon technology for most of their administrative tasks. This work includes, among others, bookkeeping, inventory managing and email. The advent of the Internet has also substantially contributed in bringing down the costs of communication and marketing. In a nutshell, technology has reduced the overall cost of business operations.

New Business Opportunities: The explosion of Internet and e-commerce has opened up a plethora of opportunities for all types of businesses. New management methodologies, such as Six Sigma are easier to implement due to statistical software. Also, companies are able to train their own employees using in-house Six Sigma software programs, and as a result, save money on labor costs.

It is now possible to have many business functions operate on autopilot. This has opened up new opportunities for software development companies and business consultants. Another business trend that has opened up as a result of advancing technology is outsourcing. It is now possible for a company in America to have its data entry and customer service centers in overseas countries such as the UK. In this way, companies can service their customers 24/7.

Indispensable Components of Small Businesses

It is difficult to think of a situation where businesses can do without technology and computers today. It is extremely difficult to say whether businesses depend on computers or computers created business opportunities.

Software Specific To Small Businesses

Certain powerful, yet simple software has come to the rescue of small businesses in reducing their tasks and opening up new channels. Simple applications like spreadsheets and word processing helps them maintain accounts, finances and keep track of correspondence. These applications allow the users to customize reports and other functions to suit their particular business.


Both men and women in business have adapted successfully to new technology. But the SBA report cites the general decline in skill levels of people, which may eventually result in an overall reduction of income levels. It seems that people get used to technology doing all the work and tend to neglect their skill development. It is up to individual companies to make sure that their employees are still able to do crucial tasks without the assistance of computers, if necessary.

How To Organize Your Computer Cables

What You Need to Know Before Buying a Wireless Multi Room Audio System

Multi Room Audio System

After months of contemplating, you have decided that you are ready to invest in a multi room audio system for convenience reasons. Who doesn’t want to enjoy today’s top hits in one room while listening to oldies in another. You no longer have to run complicated wires or carry your phone with you into every room. A wireless connection along with wireless speakers allows you to stream your audio across multiple devices. You’re ready to take the plunge but you are not sure where to start when it comes to researching. Read on for tips what you need to know before you decide on this limitless setup.

The Quality of Sound

It’s quite obvious that sound is what you’re seeking. Yes, but what do you want your enhanced sound to do for you? A multi room speaker system is cross functional and can serve many purposes whether it is listening to a game on the outside patio or entertaining guests in your home. Finding the right set up speakers to deliver the results you are seeking is key.

If you’re looking for something that can give clear sound in up to 32 rooms, look no further than the elegant HEOS by Denon lineup. Even the most compact of the lineup, HEOS 3, has two custom full range drivers that deliver impeccable bass and high frequency. The HEOS 3 would work well is a small den area. The HEOS 5 offers top of the line sound that can light up any living room. With four custom drivers, one radiator and four Class-D amplifiers, entertaining a small crowd is simplified.

Multi room audio is mostly known for the ability to synchronize. Being able to play the same sound throughout several rooms simultaneously is key. If Bluetooth streaming is important to you, you will want to find speakers that have that capability.

Ease of Use

A multi room speaker system used to mean big boxy speakers with wires running rampant. Today, technology has upgraded the masses to wireless, making the use of wires slim. Setup and installation are typically easy. As with most every system, there is a central application that acts as the command center. The application can be accessed from a tablet or phone. Consider checking out the connectivity for your system and how complex the application may be and what audio streaming sources are available (Pandora, Sirius XM, Tidal, etc.).


When using a home audio system for television watching purposes, some wireless speakers are only compatible with their respective television brand. It is important to understand this before making a purchase. It would be unfortunate to get home only to find out they cannot be used with your television.


Aesthetics is another component to consider when deciding on a system. Your speakers should complement your decor. Most speakers come in the standard colors: Black, chrome and white, however, Bose produces bold colors such as red and teal. Aside from color, the architecture of speakers varies. From traditional rectangular shapes to egg shaped and even triangular speakers, there is possibilities are there. If size is a factor, wireless speakers can be as small as a smart phone and as large as a small box.

There you have it. Some of the more important things to consider when deciding on multi room audio. You will want to make sure that you figure out what you want your sound to do for you. Don’t forget about installation. It is something you can do on your own and that the application is easy enough for you to understand and use.
