Medical electronics

Article Abstract:

Superconducting quantum interference devices (Squids) can map neural activity and pinpoint such things as the source of epilepsy. Painless and noninvasive magnetic stimulation is also being researched. Small, light implantable defibrillators with crucial intelligent sensing are being developed by several companies, and engineers hope to bring together a defibrillator, pacemaker, and heart arrhythmia regulator in one device. New volumetric imaging techniques can be applied to data from X-ray computed tomography, magnetic resonance images, or positron emission tomography to display three-dimensional images of regions of the body. An ultrasound technique for imaging blood flow in real time came under wider use in 1988. Lasers can now be used to sculpt corneal tissue, treating everything from nearsightedness to glaucoma. Lasers can also be used with light-activated chemicals to kill cancer cells and blood-borne viruses.

Next-generation race bogs down

Article Abstract:

Japan's Institute of New Generation Computer Technology (ICOT) researches the development of fifth-generation computers capable of processing large-scale knowledge bases. The US National Science Foundation recently sent a team of scientists to Japan to evaluate that country's Fifth Generation Computer Project. The reports are mixed: some say that the Japanese are ahead of the US in some areas of artificial intelligence, while others dispute this. Computer scientist Carl Hewitt from MIT says that ICOT is a commercial rather than scientific project, but that Japan's work in parallel computing should be taken seriously. ICOT develops languages and architectures for concurrent symbolic computation; other Japanese labs develop pattern recognition and expert system applications. The US Darpa strategic computing program is behind schedule. Europe's Esprit project emphasizes commercial applications.
