Micro relays can challenge transistors
Article Abstract:
Cavendish Kinetics is developing new microchip technology which will offer superior programming capabilities. The technology uses arrays of relays in place of transistors. Each relay is only a few microns long. Electrostatic action pulls a cantilever in the relay down to a metal plate where the relays can be reprogrammed into an open or closed pattern to store a logic. It is the combination of speed and programmability which makes the technology superior to other technologies, including flash memory and ROM. The devices are also highly resistant to temperature extremes, vibration and radiation.

Radar keeps its ear to the ground
Article Abstract:
SearchWell is developing a ground radar system that uses a wide frequency range. The system is extremely compact and lightweight, and uses an antenna located at the end of a 2 mt long boom. Scan information is displayed on a black and white LCD display. The prototype system has been shown to be able to detect large, buried objects down to 1.5 mt and smaller items nearer the surface. It can identify leaks sites, and is able to detect both plastic and metal pipes.

New materials show no resistance to success
Article Abstract:
New methods of producing cheap magnetic sensors will use 'collosal' magneto resistive (CMR) materials whose resistance changes rapidly when they are near a magnetic field. The new devices have been produced by growing a CMR layer next to a boundary of substrate crystals. The devices are sensitive to density changes around one thousandth of a Telsa, with a resistance change of 1-2%. They work at room temperature.
