Abstract: The invention includes an optical pulse-forming switch (30) interfaced with a pair of synchronised flip-flops and a phase detection and counter control circuit (39) which senses rotation extent and direction. The counter control circuit (39) drives a counter (10) that stores the number of passed angular increments and stores direction of rotation, the counter (10) being interrogated and reset at regular time intervals. Thus, the input shaft rotation is converted into a digital quantity by maintaining a running summation of counter values. The operator reference indicator (1) is accordingly brought up to date following each input conversion.

Abstract: A binary number substitution mechanism includes first and second storage arrays addressed by first and second portions, respectively, of an input binary number, producing a substitute output binary number. The input binary number represents a predetermined number of microinstruction addresses in a read-only store, and the output binary number is representative of microinstruction addresses in a main storage device. Only a limited number of the possible input binary numbers are required to access the first and second storage arrays to read out selectively stored binary numbers to create a limited range of output binary numbers unique to each of the limited number of the input binary numbers. 
     Further, compression of the range of output of binary numbers as substitution for certain ones of the binary input binary number is achieved by addressing the first and second storage arrays by first and second portions of the input binary number to which a certain number of the input signal line of the first and second portions are common.

Abstract: An encryption system is disclosed which is based on channel destination addresses for a time division multiple access (TDMA) satellite communications network. A superframe initialization vector is transmitted from a master station to all other stations in the network. A plurality of frame initialization vectors is sequentially generated at each station in an encryption engine, from the superframe initialization vector, using a key which is common only to authorized users within the network. Each data channel is initialized with encryption bits produced by exclusive ORing the channel destination address and the frame initialization vector for the frame in which that channel is to be transmitted, and then passing the output of the exclusive OR through the encryption engine (400) using either the same key or a second, different key. These encryption bits are combined with the channel data (54) in an exclusive OR circuit (404) for TDMA transmission via the satellite transponder to the receiving stations. The decryption process at the receiving stations parallels the encryption process at the transmitting stations, so that clear-text data is output only at the destination addressed where the intended recipient has the same key as the transmitter. The system enables the synchronization of encryption engines at separate, geographically remote stations and permits the decryption of encrypted channels at any time within a TDMA frame.

Abstract: A servo system for use with apparatus for reproducing a disc on which PCM signals have been modulated by a run length limited code and which are recorded at a constant linear velocity.

Abstract: Un mécanisme d'entraînement comprenant une vis entraînée (16) et des moyens à écrou (17) coopérant avec la vis comprend un dispositif de correction du jeu régnant entre la vis et les moyens à écrou. La correction se fait électroniquement par modification de deux trains d'impulsions (A, B) qui sont générés par un générateur d'impulsions (19) qui est synchronisé avec le mouvement de la vis. A partir des deux trains d'impulsions, on tire des informations quant à la position et au sens du mouvement d'une unité mobile (11) qui est connectée au moyen à écrou et qui, par exemple, peut être une unité d'impression dans une imprimante ou une machine à écrire. Une valeur mesurée ou estimée du jeu est mémorisée numériquement avec une résolution d'un quart de la période des trains d'impulsions. Cette résolution est quatre fois supérieure à la plus petite distance de déplacement de l'unité mobile. Les deux trains d'impulsions (A, B) sont combinés dans un dispositif de modification de signaux (21) de quatre manières différentes et d'une manière sélectionnée de deux successions opposées pour effectuer le déplacement d'un flanc prédéterminé (8) dans l'un (B) des trains d'impulsions d'autant de pas d'un quart de période que cela correspond à la valeur mémorisée du jeu et dans un sens correspondant à la succession sélectionnée.
