Abstract: A binary resistor network is provided for the labelling of related components of binary or binary-converted images and for artificial vision comprising a plurality of peaks each joined by arches forming binary resistors. Each peak is provided with an elementary processor which enables, with the assistance of a central controller, the association of at least one associative function with each of the arches and a binary constraint with one or more peaks, thus making possible to provide for selective processing of data stored at the site of each of the elementary processors. Each arch of the network is equipped with an associative OR function and forms an accelerated Manchester chain, the establishment time of the network through application of local binary constraints thus being thus linear with the number of peaks.

Abstract: Inside a range of action defined by a station, the station is able to generate therein an enquiry message followed by a silence zone. The station then selectively analyzes the respective contents of a plurality of disjoint time intervals from this silence zone. In the event of obtaining in one of these time intervals, chosen randomly by a single portable object, a content identified as a specified response message associated with this portable object, the station generates a selection message intended for this portable object, which, on reception of this selection message, generates in its turn an acknowledgement message. There follows provision for a phase of transactional communication between the selected portable object and the station.

Abstract: The audiovisual telecommunication terminal makes it possible to orient the flat screen relative to the position of the face of the operator in front of the same. The terminal comprises means for the flexible driving of the mobile part (20) carrying the flat screen relative to the fixed part (10). The transmission is of the "pulley block" type and uses a motor (12) driving a belt (8) fixed on the one hand to a drive shaft (18) and on the other to the fixed part (10) in order to exert tension on the mobile part (20). The reverse movement can be brought about by helical springs (19).

Abstract: A earth station calling another station sends a link setting-up a request to a control station. The control station memorizes in a transformed reference system the contour of a global geographical coverage including all the earth stations together with the earth positions of the latter. Subsequent to the request, the control station simulates the optimum evolution of the radioelectric coverages of the satellite so as to include, both on emitting and receiving, the calling and called stations in respective coverages with guaranteed minimum antenna gains. The total power of the satellite and the positions of the stations are notably considered in this simulation. If the result of simulation is positive, an emission authorization is sent by the control station to the calling station, and satellite antennae are reconfigured by phase shift and power control values emitted by the control station.

Abstract: An interactive optical transmission system including a transmitter assembly (EE) with a FSK DFB laser (10) and a receiver assembly (ER) having the same type of DFB laser (20) and functioning as a photoreceiver. In order to make this system interactive, the receiver (ER) is provided with a channel selection circuit (40) able to supply a current which will place the laser (20) of the receiver assembly (ER) well above the threshold and make it function as an amplitude shift keyed transmitter. The beam transmitted by said laser (20) will raise the optical transmission line (FO) to the transmitter assembly (EE). An amplitude demodulation (48) will make it possible to restore the selection code and control the appropriate information channel (S).

Abstract: Decoding apparatus provides the maximum likelihood decoding of a sequence of samples of the type implementing a Viterbi type of decision algorithm that defines an initial decoding trellis. Sub-sampling apparatus sub-samples the initial trellis by a ratio p to preserve nodes corresponding to one sample out of p consecutive samples. This sub-sampling apparatus associates a p order antecedent node to each preserved node. Trace-back apparatus traces an optimal path back in the sub-sampled trellis by associating the p order antecedent node for each preserved node. The trace back apparatus designates at least the last two nodes of the optimal path. Over-sampling apparatus over-samples the designation of the last two nodes of the optimal path. The factor p is an integer greater than 1 selected so that there is a single path between a node and its p order antecedent in the initial trellis. Hence the bit rate is increased by a factor p, without loss of information.
