Patent DE-4018381-A1 (DE)
Inventor: HINTSTEINER HERBERT ING GRAD
IPC: H04Q3/62
Filed: 1990-06-08
Abstract: 2.1 In data transmissions in communication switching systems, the frequency of seizure of the central processor during the input procedures is to be greatly reduced. The input procedures or input configurations are to be converted into data records which are in each case optimum for a data terminal, in such a manner that no program changes in peripheral devices are required for adapting these to already existing structures. 2.2 When a traffic route provided for data connections is selected, initially only one connection is established to a processing device. The identity and the characteristics of a calling subscriber terminal are transmitted by the switching system to the device and it receives the dialling information emitted from there and the input information. In the processing device, various memories are selected for checking the overall input information items for plausibility and completeness. It is only after this check is positively concluded, that a data link to a data terminal is set up and a matching output data record is transmitted. 2.3 The method has the result that the central processor does not need to be seized with each individual data input. In addition, newly added input terminals and data terminals can be matched to existing structures without having to carry out modifications in these peripheral devices. <IMAGE>

Title: Semiconductor infrared detector - is used as far infrared detector utilising adiabatic transport around detector edges
Inventor: KLITZING KLAUS V PROF DR
IPC: H01L31/08
Filed: 1991-01-18
Abstract: The epitaxially constructed semiconductor detector for the near infrared (50 microns to 1000 microns) utilises the adiabatic transportation. The detector comprises four resistive contacts (30,32,34,36), two situated at the ends of a central conductive channel (24) and one at the end of two smaller channels (26,28). Two Schottky gates (38,40) are located across the central channel. An edge region canal containing electron clouds is formed around the edges of the detector when the detector temperature is reduced to 1.3 deg.K and a strong magnetic field is applied through the detector. The electrochemical potential of the edge region canal is determined by the contacts in the canal, the current, the magnetic field strength and the gate electrodes. When infrared radiation strikes the detector the resistance between contacts in the edge region canals changes due to interaction with carriers in the detector, thus providing a means of detecting infrared light. USE/ADVANTAGE - Improved response time and increased sensitivity in comparison with existing far infrared detectors. Suitable for IC manufacturing techniques.

Filed: 1991-11-28
Abstract: In a testing device (PRE), with the aid of which the functional testing of circuit boards (VPL) equipped with programmable integrated circuits (PIS) is provided by means of measuring sensors (MF1...MFn) - usually in the form of needle adaptors - additional means for generating circuit-specific programming signals (ps) and at least one additional circuit-specific programming routine (PR) are arranged. As a result, a programming of programmable integrated circuits (PIS) on equipped circuit boards (VPL) is accomplished as part of functional testing. With the aid of the method according to the invention a considerable reduction in cost is achieved in the production of circuit boards (VPL) or assemblies with programmable integrated circuits (PIS) by the avoidance of separate programming on a special programming terminal and program-individual stock keeping of the programmed integrated circuits (PIS). <IMAGE>
