A computer that could hear poodles

Article Abstract:

An analog neural network computer invented by two scientists at the University of Pennsylvania, a computer network security system invented by a former American Express vice president, and a way to preheat catalytic converters have received patents. The computer translates light or sound into analog patterns that it can recognize up to a thousand times more quickly than computers can recognize digital patterns. Because it is a general-purpose neural network computer, it can be trained for many different tasks including voice recognition. The security system also uses voice recognition. Users input their voices and the system stores them for later identification. When users want access to the network, the system prompts them to call a phone number and repeat the words they stored. The system compares the spoken and stored words to allow or deny access. The catalytic converter heater eliminates inefficiency at start-up.

Duties ended on computer flat screens

Article Abstract:

The Department of Commerce revokes the import duties imposed on flat-panel displays for laptop and notebook computers and high-definition television (HDTV), despite the protests of some US companies which insist that the duties are important for the development of a domestic advanced-screen technology. The import duties total 63 percent; their assessment has been based on screens made by foreign manufacturers, notably Japanese companies. While certain business sectors argue that import duties will protect the US' global competitiveness, computer manufacturers, such as Apple, IBM and Compaq, have argued that the tariffs increase the costs of their machines, making them less competitive in foreign markets and thereby encouraging them to shift production to other countries.

'Breeding' computer programs

Article Abstract:

John R. Koza, a computer scientist at Stanford University, receives a patent for 'breeding' computer programs. Koza's method draws on Darwin's theory of natural selection, allowing computers to deal with complex tasks by testing many programs and 'mating' ones that work best. The goal is to allow computers to develop their own software and teach themselves. According to Koza, 'genetic' approaches to software development originated in the 1970's as part of research into artificial intelligence. Koza's particular technique was inspired by observing the way chromosomes combine during sexual reproduction.
