Title: Motor vehicle speed limiting device e.g. for poor visibility - is activated by existing fog-lamp switch to prevent overspeeding without additional action by driver
Inventor: LUETZE NORBERT DIPL ING
IPC: B60Q1/20

Title: Position-measuring appts. using spatially modulated gratings - produces different aperiodic waveforms from various functional dependences of local grating period on direction of modulation
Inventor: HOLZAPFEL WOLFGANG DR
IPC: G01D5/38
Filed: 1992-04-11
Abstract: A conventional three-grating interferometer delivering signals with a period equal to half of the grating constant is modified by the provision of ''chirped'' gratings (A,B,A') on which the space between adjacent rulings varies considerably from one end to the other. For small displacements of the middle grating (B) each partial grating produces a signal of different frequency. The superposition of such signals yields an aperiodic waveform similar to the superposition of a continuous frequency spectrum on a Fourier integral. USE/ADVANTAGE - For incremental length and angular measurements, the very narrow signals produced are within broad limits independent of luminous intensity and distance between the scanning grating and the graduated carrier.

Patent DE-4334264-A1 (DE)
Title: Bit-error trigger
Inventor: DRAVING STEVEN D
IPC: G01R13/32
Filed: 1993-10-07
Abstract: A trigger circuit uses a pair of comparators in order to compare an input signal both with an upper threshold and with a lower threshold and in order to generate a voltage-threshold signal which shows whether the input signal is between the lower and upper thresholds. A clock-edge signal is connected to a programmable monostable multivibrator in order to generate a signal which is high for a defined period of time which starts with the clock edge, in order to generate a time-window signal. The time-window signal is gated with the voltage-threshold signal using an AND function, after which the voltage-threshold signal is delayed for a selected time. The result of the AND function of these two signals is an output signal which defines whether the input signal is within the region between the lower and upper thresholds during a time window around the clock edge.
