Abstract: The digital speed control system, esp. for a motor vehicle, employs a logic circuit with an acceleration register (12), a counter (14), a movement register (16) and a correction register (18). The circuit is triggered by input through an AND gate (38) and an OR gate (39) and a three-way mode (44) to the T (trigger) input terminal on the registers (12, 14, 18). The movement counter (16) is operated by a coincidence AND gate (32). Connections between the various registers are made on the easier of one line per binary stage for acceleration (A1, A2...A128), velocity (V1, V2...V128), velocity complement (V1, V2...V128), speed (S, S2...S128) and error (E1, E2...E128). The last stage on each of the boundary registers connects to an overflow line (48, 22).

Abstract: An ignition system which is responsive to timing signals generated in timed relationship to the operation of an internal combustion engine for providing firing spark to operate the engine. The system uses two capacitors to provide an adaptive dwell system wherein the percent of time that ignition coil current is limited at a fixed magnitude is made variable with respect to the engine rpm.

Abstract: A driver circuit is coupled to the stator windings of a brushless three phase DC motor which is responsive to the open circuit back EMF voltage induced in the next stator winding to be energized as a permanent magnet rotor of the motor is caused to be rotated for producing phase current drive to the stator winding in synchronous with the operation of the motor. The driver circuit includes an increment drive circuit for supplying periodic switching command signals in succession to a switching circuit to produce phase current drive in each stator. The increment drive circuit increments a switch command signal to cause phase current through the next phase stator winding in reference to the magnitude of the EMF voltage induced across said phase stator winding falling below a reference level. A feature of the invention is that the frequency of the periodic switch command signals is varied during starting of the motor dependent on the magnitude of starting potential supplied to the driver circuit to prevent the motor from "locking" which would otherwise inhibit start thereof.

Abstract: An electronic triggering circuit for an ignition system develops electric signals which correspond to the closing and opening of breaker points to supply variable dwell (ratio of on-to-off) pulses to the primary winding of the ignition coil at speeds below a predetermined RPM. The circuit operates to supply constant dwell pulses to the primary winding of the ingition coil at higher engine speeds.

Abstract: Systeme d'allumage (10) sensible aux signaux d'allumage produits dans une relation de synchronisation par rapport au fonctionnement d'un moteur a combustion interne et produisant des etincelles d'allumage pour le fonctionnement du moteur. Le systeme utilise deux condensateurs (C, A) pour obtenir un systeme adaptatif de pause dans lequel le pourcentage de temps pendant lequel le courant de la bobine d'allumage est limite a une valeur fixe varie en fonction du nombre de tours du moteur.
