Title: Electrical connector laminate for flat components, e.g. PCB and LCD - using metal- or graphite-coated hard mineral particles to provide conductivity perpendicular to it plane
Inventor: HAMPEL BRUNO DR
IPC: H01R4/04
Filed: 1991-05-06
Abstract: The connector has a carrier layer (1) with a printed-on layer (2) of metal or graphite-filled high polymer paste and a layer of heat sealable high polymeric material. It is electrically conductive perpendicularly to its plane by way of discrete conductive particles, pref. irregularly-shaped particles which are harder than the carrier layer (1) and which are esp. metal- or graphite-coated hard mineral particles, 3-25 microns in size.

Title: Communication terminal handset cord replacement system - uses full duplex radio transmission line and has terminal with base station and independent unit
Inventor: BARAN MARIAN
IPC: H04M1/72511
Filed: 1992-11-19
Abstract: The full duplex transmission line has associated radio channel pairs. Each terminal has a base station (BS) and an independent unit (HA). Each of these has a transmitter (S) and a receiver (E). An accumulator supplies power to the independent unit (HA). In the rest position, the base station (BS) and independent unit (HA) are coupled together via galvanic interfaces (GS).
