Pentagon lets civilians use the best G.P.S. data

Article Abstract:

Six years ahead of schedule the U.S. government has made more accurate G.P.S. service available to private users. Commercial and recreational demand increased faster than expected, prompting the move. Previously, nonmilitary users received data accurate within 100m (330 yards). Now it is within a 22m (72 feet) range. The Commerce Dept. estimates the market at $8 bil for 2000, on track to double by 2003. Researchers are developing the next iteration of the triangulating system. In the Differential G.P.S. system, ground based transcievers will check signals generated by the satellites that form the present network. This should result in faster, more accurate service for consumers.

Tweaking technology to stay ahead of the film pirates

Article Abstract:

To protect commercial recordings of movies on DVD or videotape from unauthorized reproduction by consumers, most DVDs and videotapes include some type of copy protection in the form of coded signals that do not adversely affect playback of the original but will effectively render any taped copy impossible to watch. Coded signals in a part of the video signal called the blanking interval are used to confuse the circuitry of the VCR, confounding its gain control. For DVDs, the same technique is used, and another method called color striping is added to mask the image.

Remote keyless entry: staying a step ahead of car thieves

Article Abstract:

Consumer electronics and automobile manufacturers are making innovative strides in remote keyless entry technology or R.K.E. systems. Introduced in the 1980's, keyless entry and security systems for automobiles have caught on and have nearly reached 'standard-equipment' status instead of being reserved for luxury automobiles. As popularity increases and the costs decrease, these devices include several anti-theft and convenience innovations. The next step for auto manufacturers is the 'keyless car' - two models have been developed by Lexus and Mercedes-Benz.
