Terminals for commerce In a range of four interactive ter- minals, three offer commercial users a choice from a basic teletype com- patible vdu up to a sophisticated intelligent microprocessor controlled terminal wi th 3270 emulation. The fourth is a bi-directional printing terminal.

The foundation of the range is the Newbury terminal, a teletype com- patible 96 pso ascii vdu with a dis- play of 24 lines of 80 characters per line and a 7 x 5 dot matrix. Baud rates are from 50 to 19 200 in selec- table half or ful l duplex mode.

CRT for a tv camera viewfinder

Viewfinder tube

For hand-held tv cameras a miniature viewfinder crt is available. This ert has a useful screen area of 60 x 45 mm and is suitable for direct view without the need of a magnifier. The tube has a small diameter (14mm) neck, requir- ing a low power deflection coil. The weight of the basic tube is 140 g. The design is based on tubes developed for military helmet mounted display syste ms.

Students' design awards 'Worldview One' was designed to interpret and display signals trans- mitted bY meteoralogical satellites. It won for its designer Guy Dance, a student at the Dorset Institute of Higher Education, one of the five £250 awards in the Design Council Molins Design Competition. The com- petition is open to students in Britain fol lowing diploma or first degree courses, primarily in engineering.

Other winners were Chris Cole from Hatfield Polytechnic for his cable gripping system aboard cable ships; a morse code decoder, printing messages automatically on teletype,

was David Deaville's entry from Durham University. Nick Massey devised a fi l ter to equalize telephone lines for computer data transmission. At Edinburgh University he used an adaptive transversal f i l ter construc- ted with eight tap shift registers. A jig for calibrating inspection probes won Michael Still of Loughborough University his award.

pH meter Portable pH meters feature a digital Icd. They operate on nine volt batteries and have slope adjustment and accuracy to wi thin 0,02 pH over the ful l 0 to 14 range. They not only measure pH, but also determine activity in milli- volts and sample temperature. With an accessory, they can be used with a standard ac source.

Keyboards drivers and shifters Designed for demanding environments, the alphanumeric acsii encoded cosmac rip keyboards from RCA use membrane key switches. They are available in a 58 key qwerty configuration, the vp 601, or a 74 key type.

Also from Norbain is a high voltage, gas discharge cathode driver and level shifter. These monolithic devices feature dielectric isolation enabling a high voltage breakdown isolation. The technology involves dielectrically isolat- ing the output device on its own region of the substrate.
