Title: Second order numeric filter for signal processing - uses clock source with three clocks controlling synchronised and interlaced multipliers
Inventor: ROOY GERARD
IPC: H03H17/02
Filed: 1975-10-01
Abstract: A signal processing system is used for analogue data varying as a function of time. The process is based on a second order numeric filter providing two magnitudes of time varying outputs in a low and pass band. The filter has a variable cut and fall-off frequency. The analogue input amplitude is converted to numeric form and processed as parallel streams of data, each such stream carrying identification bits and attenuation information. Data streams are fed from the input analogue to digital converter to a frequency multiplier. A clock source provides a parallel predetermined frequency pulse stream as three parallel outputs feeding three separate interlaced multipliers.

Patent FR-2375076-A1 (FR)
IPC: B60T8/17
Filed: 1977-12-20
Abstract: In the antilock device, in the event of a risk of locking, the brake pressure is reduced when a speed differential signal ( DELTA v-signal) exceeds a predetermined threshold value. This speed differential signal represents the difference between the wheel's speed of rotation and a hypothetical line representing the translational speed of the vehicle. For braking with optimum wheel slip at which maximum adhesion occurs, this threshold value is adjusted proportionally to the speed at vehicle speeds below an upper limit speed (v1). Above this limit speed (v1) on the other hand, the threshold value is kept constant in order to prevent excessive heat energy being released by excessive speed differentials between the wheel's speed of rotation and the translational speed of the vehicle, which might lead to damaging of the tread of the vehicle wheels.
