Title: Method and device for interpolation of sinusoidal measurement signals, particularly from photo-electric measurement systems
Inventor: FISCHER VOLKMAR DIPL ING
IPC: G01D5/244
Filed: 1989-06-08
Abstract: In the method, and with the device, for interpolation of sinusoidal measurement signals, particularly from photo-electric measurement systems, rectified signals from measurement signals which are generated and rectified by transmitters (4) are generated with amplitude reduced by the factor k.

Title: Digital signal monitoring circuit - uses clock pulse signal as digital signal, and phase control circuit
Inventor: SCHULZ HARRY
IPC: H03K5/135
Filed: 1989-06-22
Abstract: The circuitry has two D flip-flops with inputs for a first clock pulse signal (t1), which has the same bit train frequency as the digital signal (d). The circuitry has a control circuit (3) for phase adjustment of the digital signal to that of the first clock pulse signal, in dependence on the phase advance. The first clock pulse signal is supplied to the first D flip-flop (1) via an inverter (5), and to the second D flip-flop (2) directly. The digital signal is fed to the first flip-flop D input. A switch, actuated by the control circuit feeds the digital signal directly to the second flip-flop D input, or couples first flip-flop Q output to second flip-flop D input. USE/ADVANTAGE - For high integration density chip testing, with digital signal phase correction.

Title: Intelligent network for flexibly processing input information - is neural network which automatically changes internal structure and modulation of fundamental oscillation
Inventor: HESS KARL DR
IPC: G06N3/04
Filed: 1990-12-12
Abstract: The system for representing a signal in the form of modulations on a fundamental oscillation contains a receiver which represents an input signal as a three-dimensional wave in a Cartesian coordinate system. The amplitude of the square of the wave is compared with existing wave values at defined locations and times to detect modulation information if they coincide. If there is no coincidence there is no information in the signal for the receiver and the directionally reversed and spatially mirrored fundamental wave is displayed. The amplitude values not leading to coincidence are stored and the waves used for modulation with spatial mirroring but direction maintained. USE/ADVANTAGE - For flexibly processing input information in neural networks using automatic internal restructuring.
