Electronics

If you're not at the top of whatever workflow chart you find yourself a part of, chances are good that you find yourself wishing your office was a little bigger. Even though technology makes our lives easier, it certainly takes up a lot of space. And with more and more gizmos and gadgets coming out each year, the wires, manuals, and add-ons can really take their toll on your already cramped space.

Office space clutter is not only annoying, but it can also be one of the fastest ways to lose a client's or coworker's respect. Here are a few tips and wholesale electronics devices you can use to cut down on the clutter and create a neat, clean, professional-looking office.

In the world of monitors, big is NOT beautiful. The first thing you should do if your desktop acreage leaves you wanting is to toss the huge monitor that came with your computer and go out and buy yourself a flat panel monitor. They're not cheap, but I promise it's the best birthday present you'll give yourself until you're on the top of the workflow chart (i.e. BMW...).

Go wireless. Keyboard and mouse wires are unnecessary evils now that wireless options are cheap and readily available. An optical mouse eliminates the need for a mouse pad if you are really in a crunch for space. Depending on the size of company you are working for, wireless internet routers and wireless cards for both PCs and laptops are options to help cut down on the miles of wires that seem to run to the back of your computer. Wholesale electronics vendors typically carry package deals on wireless keyboards and mouses that make this option even more economical.

Keep the wires under wraps. Some devices don't come without wires (yet), and chances are you've got dozens of wires running under your feet as you read this article. Use Velcro strips, ties, or tubing to bundle wires together. When you upgrade your wires and connections, check the wholesale electronics section to see if they carry wire organizing devices. Not only does this keep you from pulling the printer cable out of the back of your computer each time you stretch your feet, but it will also make under your desk look neat.

Get personal with your audio. Have you ever noticed that the stylish, modern shapes that computer speakers come in don't typically stack well? If you are working in a public workspace and have to hunch near your speakers to listen to your music, consider switching to headphones. Wireless headphones are available from a number of vendors and the prices are quite reasonable. Combination microphone and headphone headsets also reduce the need to use awkward desktop microphones.

Take your office with you. Over the last few years laptops have really come into their own. You can get all the computing power you'd ever want out of a desktop without having to worry about an extra monitor, keyboard, mouse, and speakers - and even better yet, you don't have to worry about all the wires that come with them. Any upgrades or add-ons you need can usually be picked up pretty inexpensive from any wholesale electronics dealer.

Three auxiliaries are better than one. Printers, copiers, and scanners are integral parts to any home business or office. But you don't need to sacrifice tons of deskspace to have them all. You can often save quite a bit of money buying 3-in-1 combinations of these auxiliaries rather than buying them separately. You also integrate all of your tech support needs for the devices because they are all made by the same company.

The devil is in the details. Little things can really go a long way in cleaning up the clutter and opening up desk and office space. USB flash drives store more than their bulky disk counterparts and you can rest assured that they'll be compatible wherever you go. Under-desk trays for keyboards and mice, clip on copy holders that attach to your monitor, and stacking paper trays will all help your home or work office look and feel neat and organized.

High definition DVD represents an evolution of the present DVD format. Regarding its video and audio quality, high definition DVD is much better than the actual DVD as this was compared to the features of the old VHS videotapes. The birth of the high definition DVD was determined by the evolution of the television sets which have become capable of displaying high definition pictures, fact that requested a step forward for the home video.

In other words, high definition DVD's aim is to provide 1080 lines of video resolution, compared to the 576/480 lines presently offered by the actual DVDs.

Why would anyone want a high definition DVD? For the same purposes why people prefer DVDs over the old video tapes. Regardless the high resolution video and audio features, the bigger storage capacity of high definition discs will eventually represent the end of single movie multi-discs sets, an important quality that will allow for more extra features to be included on one disc. For example, an entire season of a television show will fit prefectly onto just one single disc.

But what will be the destiny of the present DVDs? No matter the high definition DVDs anyone will choose, they will definetely be compatible with the present DVDs. This means that any DVD collection does not need to be replaced. This is possible because many of the present DVD players have an upscale feature (meaning to increase the video resolution using digital manipulation) that allows them to change the existing DVD movies to a higher definition. This feature will later be used for all high definition DVD players. Although this upscaling operation will not provide the same 'unforgettable experience' as high definition movies, it will allow the existing DVDs to be shown in their best possible way, without losing any resolution.

You will find more info on the compatibility for each specific format in the FAQ section.

Is it possible for a computer to playback high definition DVDs? Presently, there are no computer systems on the market that are capable of playing these high definition discs. The moment the hardware and software arrives, most of the 2.8 GHz or higher rated computers will definetely be able to playback high definition DVDs without any problems occuring. But the highest video/audio resolution movies (like 1080p with high definition multi-channel audio) may require a faster computer or/and a good audio decoding hardware.

the providers of the PowerDVD software, Cyberlink, has already displayed a playback of a HD DVD using PowerDVD and an Intel Pentium D processor at the Digital Hollywood conference in September 2005. More info on this presentation can be read in Cyberlink's press release.

What are the formats for the the high definition DVD? The two main formats are: HD DVD (pay attention not to cofuse it with the general term of High Definition DVD, which refers to any high definition DVD formats) and Blu-ray disc (BD).Some formats called EVD and FVD can be found mainly in Asia.

In conclusion, high definition DVDs represent the future of home video display.

Video technology has increased significantly over the past years, and is continuing to grow at an incredible rate. Digital Video Disc’s aka DVD’s are the most likely the last big jump in consumer video technology that everyone is familiar with. To keep up with the ever advancing world of electronics a new format of video storage will be released soon called Blu-ray.

Blu-Ray is a next generation optical disc that will blow the socks off of what we all know today: DVD. Conventional DVD’s use a red laser that have long wave lengths, which limits the storage capacity on a disc. Blu-Ray uses a blue laser which has much shorter wave lengths. Because the wave lengths on the Blu-Ray are much smaller it can focus on a spot with much greater precision, allowing for data to be packed much more tightly than the red laser DVD’s.

Blu-Ray discs can hold up to 50GB’s of information which 10 times that of a 4.5GB DVD. 10 times the storage will greatly increase the amount of information that we can save on any one disc and will change the way we save information. Dual Layer Blu-Ray discs will be able to hold up to 4 hours of High-Definition Video. High Definition video is going to hit big here, Blu-Ray is an example of a technology that is going to make it happen. 50GB is probably comparable to size of many of our hard-drives, and to picture having all of that information on a small disc that we can slide into a pocket and take wherever we want is a bit scary.

Expect to see Blu-Ray replacing DVD and VCR over the next few years, following along with the transition of video to High Definition Video. Video isn’t the only thing that will benefit from Blu-Ray technology; I would expect that it will also become the standard for PC and other types of storage.

How GPS Works!

The Global Positioning System is vast, expensive and involves a lot of technical ingenuity, but the fundamental concepts at work are quite simple and intuitive. Garmin GPS and Magellan GPs are important systems.

When people talk about "a GPS," they usually mean a GPS receiver. The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). The U.S. military developed and implemented this satellite network as a military navigation system, but soon opened it up to everybody else. Each of these 3,000- to 4,000-pound solar-powered satellites circles the globe at about 12,000 miles (19,300 km), making two complete rotations every day. The orbits are arranged so that at any time, anywhere on Earth, there are at least four satellites "visible" in the sky.

A GPS receiver's job is to locate four or more of these satellites, figure out the distance to each, and use this information to deduce its own location. This operation is based on a simple mathematical principle called trilateration. Trilateration in three-dimensional space can be a little tricky, so we'll start with an explanation of simple two-dimensional trilateration.

3-D Trilateration Fundamentally, three-dimensional trilateration isn't much different from two-dimensional trilateration, but it's a little trickier to visualize. Imagine the radii from the examples in the last section going off in all directions. So instead of a series of circles, you get a series of spheres. If you know you are 10 miles from satellite A in the sky, you could be anywhere on the surface of a huge, imaginary sphere with a 10-mile radius. If you also know you are 15 miles from satellite B, you can overlap the first sphere with another, larger sphere. The spheres intersect in a perfect circle. If you know the distance to a third satellite, you get a third sphere, which intersects with this circle at two points.

The Earth itself can act as a fourth sphere -- only one of the two possible points will actually be on the surface of the planet, so you can eliminate the one in space. Receivers generally look to four or more satellites, however, to improve accuracy and provide precise altitude information. In order to make this simple calculation, then, the GPS receiver has to know two things:

The location of at least three satellites above you

The distance between you and each of those satellites

The GPS receiver figures both of these things out by analyzing high-frequency, low-power radio signals from the GPS satellites. Better units have multiple receivers, so they can pick up signals from several satellites simultaneously.
