Patent EP-0023836-A1 (EP)
Inventor: OLIVIER PAUL D
IPC: F16D23/10
Filed: 1980-08-04
Abstract: The speeds of the gearbox input shaft (16) and the gearbox output shaft (24) of, typically, a road vehicle are sensed by sensors (26, 28). The signals from the sensors are then processed, and combined (at 34) to provide a signal representative of the ratio of input shaft speed to output shaft speed. This signal is displayed by a device (36), which in the illustrated form has a pointer moving over a scale whose marks (38) correspond to the actual gear ratios available. Thus the driver of the vehicle can tell when the input and output shaft speeds are correct for engaging a particular gear.

Title: Microprocessor interface control apparatus.
Inventor: JACKSON DANIEL K
IPC: G06F13/42
Filed: 1980-02-28
Abstract: An interface (214, 215, 216) between a microprocessor chip (200) and input/output, and memory modules. The interface uses a single, bidirectional bus (214) comprised of a number of lines which is less than the number necessary to carry a complete address word or a full width data word. Information transfer is effected by transferring information in small portions utilizing two or more interface clock cycles. An encoded control specification placed on the bus (214) during the first cycle of information transfer specifies the type of access, the direction of transfer, and the length (number of bytes) of data to be moved. Two additional simplex lines, ISA (215) from the microprocessor and ISB (216) to the microprocessor are needed to complete the basic interface.

Abstract: Camera electronique mettant au point des images d'un objet sur le plan de l'image au moyen d'objectifs convenables (14) tels que ceux utilises dans des cameras 35mm. Le systeme optique est maintenu immobile pendant qu'une rangee lineaire a balayage automatique (34), composee d'une rangee de dispositifs sensibles a la lumiere, est deplacee a une distance mesuree sur le plan de l'image. La rangee lineaire est continuellement creditee d'un temps lors de son deplacement sur le plan de l'image. La sortie du signal video resultant est constituee par un train d'impulsions, possedant chacune une intensite proportionnelle a 1, intensite de la lumiere qui tombe sur le dispositif correspondant sensible a la lumiere, Une source interieure de lumiere a filaments de lignes se deplace en synchronisme avec la rangee lineaire de sorte que seulement la portion d'image qui est en train d'etre exploree par la rangee a chaque instant lorsqu'elle traverse le champ de l'image est eclairee. La source de lumiere est dirigee sur le plan de l'objet par un diviseur de rayons de sorte que la lumiere passe a travers l'axe optique de l'objectif pour garantir un maximum d'efficacite.

Abstract: Radio system for exchanging communication messages between transmitting/receiving stations moving along predetermined links and transmitting/receiving stations arranged at predetermined distances along these links and active in both directions of the links, in which systems the stations of one link are in communication with a central transmitting/receiving station. The aim is to reduce expenditure and restrict or avoid interference which can occur due to the simultaneous operation of adjacent transmitting/receiving stations. For this purpose, the central transmitting/receiving station calculates the location of each moving transmitting/receiving station at the time of the next communication message to be exchanged and then only switches on the station closest to the calculated location along the link for exchanging the communication message. <IMAGE>

Abstract: An isolated transmission of direct and alternating voltages becomes possible by means of simple electronic components which, connected in the manner of a ring modulator, apply an input voltage switched pulse by pulse to the primary winding (3) of a transformer (4), via which the potential isolation is effected. The pulse-converted voltage transmitted to a secondary winding (16) of this transformer is then switched a second time pulse by pulse with the same timing voltage in a similarly connected output circuit in such a manner that the first switching is cancelled again and thus an output voltage corresponding to the input voltage is produced (see Figure 2). <IMAGE>

Abstract: The tambourine comprises a frame (1) and a metal ring (3) associated thereto and effective to take over the stresses created by the tambourine membrane (2) in such a way as to prevent the frame form deforming due to additional stresses acting thereon during the playing. Thus, owing to the presence of the reinforcing metal ring (3), there are obviated both twisting and out-of-round problems in the tambourine frame (1) and, in addition, the center of gravity of the tambourine is brought closer to the membrane thereby improving stability and controllability as the ball is hit.

Ensuite pour une durée t2, chacun des postes ayant détecté un signal émet un signal de brouillage à cette même fréquence de trafic et les postes n'ayant pas détecté de signal prolongent l'écoute de cette même durée t2. La non réception de signal pendant la durée t2 autorise l'établissement de la communication à la fréquence correspondante.
