Abstract: Un circuit (31) de mise en forme de l'amplitude de signaux est intercalé entre une source de signaux (32) et une borne (16) d'entrée de signaux d'un circuit à modulation de fréquence d'une unité typique de transmission ou de transmission-réception de radiocommunications en phonie. Le circuit (31) de mise en forme de l'amplitude comprend un circuit d'échantillonnage (34) de haute impédance qui capte la tension de polarisation en régime permanent au niveau de la borne d'entrée de signaux pendant des périodes où aucune donnée n'est transmise. Lorsqu'un signal (53) de validation de la transmission est reçu, la tension de polarisation captée en dernier est enregistrée et des tensions décalées positive et négative (74, 69) sont générées par rapport à la tension enregistrée (40). Une des tensions décalées (74, 69) est précisément ajustée par rapport à la tension enregistrée (40). L'autre tension décalée (69) est générée par inversion de la première tension ajustée, de sorte que les deux tensions (74, 69) sont décalées d'une valeur égale dans des directions opposées. Un commutateur analogique (46) reçoit une séquence de signaux numériques et applique les tensions décalées positive et négative (74, 69) à la borne d'entrée de signaux dans un ordre qui correspond à la séquence des signaux binaires de données reçus.

Patent EP-0593760-A1 (EP)
Inventor: SASAKI TAKAO
IPC: G01M13/02
Filed: 1991-04-01
Abstract: A gear pitch error correction system of a numerical controller for a machine tool including at least one pair of gears disposed in an intermediate position on a transmission path for transmitting the torque of a servo motor to a material to be driven. A pitch error correction value per predetermined rotating angle of a gear is individually measured for each gear for each rotation period of each gear and is stored in a non-volatile memory (14b). Pitch error calculation means (E) refers to a current value register (D), reads out a pitch error data corresponding to the current position from the non-volatile memory (14b) and calculates a superposed pitch error correction value by adding the pitch error data. This superposed pitch error correction value is added to an interpolation pulse from interpolation means (B) by an adder (C) to gernerate an output pulse having the corrected pitch error, and this output pulse is outputed to an axis control circuit (18). Accordingly, a fine pitch error correction can be made in proportion to the superposition level of the gear pitch error correction value of each gear even when the number of the gear pitch error correction values for each gear is not much great.

Abstract: A system for controlling an internal combustion engine, especially a diesel internal combustion engine, is described. In this system at least one solenoid valve determines the beginning and end of the delivery of the fuel pump. Two control units determine a triggering signal (MVE) for the solenoid valve as a function of markings applied on the cams and/or on the crankshaft. A first control unit sends a first signal to a second control unit by way of a first transmission device. The first control unit sends a second signal (ASS) by way of a second transmission device. On the basis of the first signal the second control unit generates a third signal (MVO). The second and the third signal jointly determine the triggering signal (MVE) for the solenoid valve. <IMAGE>
