Title: Method and test adaptor for making contact with test-pieces
Inventor: PROKOPP MANFRED
IPC: G01R1/073
Filed: 1989-05-27
Abstract: Method for making contact with test-pieces by means of contact pins. The latter are arranged in a test adaptor where they are guided straight in a front plate and pass through holes of a clamping plate which can bend the contact pins from their straight positions. The contact pins exert increasing forces on the test-piece when the clamping plate is moved in a direction of motion which is opposite the direction of motion used for clamping the contact pins.
Patent DE-3918007-A1 (DE)
Inventor: KAYS RUEDIGER DR ING
IPC: H04N7/01
Filed: 1989-06-02
Abstract: Television signals are currently still mainly reproduced by means of cathode ray tubes. Newly developed reproduction devices with a flat screen have as a rule a matrix with picture elements which are selected in dependence on the received television signals. The matrix arrangement selection system is designed in such a manner that a particular display control circuit is only suitable for one television standard. So that video signals of different scanning standards can also be reproduced on reproduction devices having a matrix-shaped display device, the video signal is temporarily stored in the reproduction device, and before reproduction occurs, digital signal processing is carried out by means of vertical reinterpolation. The circuit arrangement according to the invention is particularly suitable for standards conversion of video signals for representation on a reproduction device with matrix display device. <IMAGE>

Patent DE-3934384-A1 (DE)
Inventor: BRAHMS MARTIN
IPC: H04B3/04
Filed: 1989-10-14
Abstract: A controllable amplifier, which has two symmetrical outputs, at which two output signals mirror-symmetrical with respect to each other are present, is used for amplification of a burst signal. To achieve the largest possible eye opening of the signals to be fed to a comparator, a predetermined d.c. voltage difference for the formation of matched signals is adjusted for both output signals. After this, the arithmetic mean values of the two matched signals are formed and are fed to a second comparator. The output value of the second comparator is fed to an integrator, to which a reference voltage is also fed. In case of a deviation of the mean values of the two matched signals from each other, the amplifier is adjusted in a compensating direction by the integrator.
