Satellite radio receiver
Satellite radio is a digital radio system that receives signal directly from the satellite. Usually this system ensures better sound quality and covers huge area compare to the traditional radio. Satellite radio requires line-of-sight position for uninterrupted signal reception. Satellite Radio is more popular in United States than in United Kingdom (UK). UK and other countries concentrate on Digital Audio Broadcasting (DAB) rather than satellite radio. Satellite radio uses 2.3 GHz S band in North America and generally shares 1.5 GHz L band with local Digital Audio Broadcasting (DAB) stations elsewhere. Presently there are several satellite radio providers offer their services such as World Space in Europe, Asia and Africa, Sirius Satellite Radio in North America. All are proprietary and non-compatible signals, requiring proprietary hardware for decoding and playback. These and other services have news, weather, sports and several music channels.
Repetitive Strain Injury
Continuous attachment with computer is detrimental to your health. Using a computer for more than a few hours a day can put you at risk from RSI (Repetitive Strain Injury). You can follow these guidelines to survive yourself from this risk.
Ø Make sure to take regular breaks away from your PC if you can; get up and walk around for a few minutes each hour.
Ø Also, try and alternate between using your keyboard and mouse rather than relying on the mouse for everything. And when you do use your mouse, move with your shoulder rather than putting all the strain on your wrist.
Ø You can buy mouse mats that have gel wrist support. You may also want to look into buying one of the special keyboards available, which have been designed to be more comfortable to use.
Ø If you have a joypad you could use a program like Joy Tokey to map mouse and keyboard controls to your controller to give your wrist and fingers a change from the same mouse and keyboard positions all the time.
There is also a useful program called Workrave (www.workrave.org) that can help prevent RSI. The program reminds you to take breaks at set times as well as letting you set micro-pauses and daily limits.
