    Abstract: The invention provides a method of verifying the integrity of sequences of data transmitted from a first station to a second station in a broadcast network during a call set up between the first and second stations. First and second encipherment seals are calculated in a control station separate from and independent of the first and second stations, respectively in response to reception of a sequence corresponding to the transmitted data sequence and in response to reception of the sequence which is received in and retransmitted by the second station. A comparison of the calculated seals for integrity verification is preceded in the control station by searching for the first seal calculated according to an identification word of the sequence which is retransmitted by the second station. The invention relates to a method of verifying the integrity of data sequences exchanged between stations respectively belonging to different broadcast networks.

    Abstract: The light pulse generator includes a source for generating a light beam, an electroabsorbent modulator for modulating the light beam into light pulses, and means for applying voltage control to the modulator. The electroabsorbent modulator includes at least two doped layers and between them at least one intermediate layer that is made of a material that is not intentionally doped, and that has an electroabsorbent material included therein. The absorbent or transparent state of the intermediate layer is controlled by a voltage applied between two of the doped layers that have doping of the same sign, the transmissivity of the modulator as a function of the voltage controlling it being at a maximum in the vicinity of zero volts and being symmetrical thereabout.

    Abstract: A process and device for the analog convolution of images, especially two-dimensional convolution operations of Gaussian type on a set of image pixels represented by voltages. The voltages are applied to a first set of capacitors. For each capacitor, one terminal is connected to a reference voltage; the other terminal is part of a network of nodes, each of which is insulated from the others. The nodes which are adjacent are connected together for a predetermined duration via a second set of uncharged capacitors. The nodes of the network are then insulated from each other again and the second set of capacitors are discharged. The steps of connecting the nodes together, insulating them from each other, and discharging the second set are repeated. Finally, the new voltages on the nodes of the network, which represent the pixels of a convolved image, are read out.
