Abstract: A frequency hopping receiver capable of real time demodulation, and a method thereof are provided. The frequency hopping receiver includes first and second frequency generators, a switch, a controller and a demodulator. The first frequency generator receives a first frequency control signal according to a predetermined control and generates a predetermined frequency first carrier wave used to generate a synthesized carrier wave for demodulating the received signal. The second frequency generator receives a second frequency control signal according to a predetermined control and generates a predetermined frequency second carrier wave used to generate the synthesized carrier wave for demodulating the received signal. The switch switches between the first and second carrier waves in response to a signal for selecting a carrier wave, to generate a continuous synthesized carrier wave.

Abstract: A device, and a method for making the same, for bonding two millimeter elements, which include a substrate having an upper face and a lower face, a conducting line on the upper face and oriented substantially perpendicular to an edge of the substrate, and two continuous bounding zones on the upper face and along the edge of the substrate, each continuous bounding zone being electrically grounded, and having a length along said edge between about two and about five times the width of the conducting lines.

Abstract: A dual-band electronic scanning antenna, with an active microwave reflector. The antenna includes at least two microwave sources transmitting in different frequency bands and having opposite circular polarizations. An active reflecting array including elementary cells illuminated by the sources is provided. A polarization rotator is inserted between the reflecting array and the sources, changing the circular polarizations into two crossed linear polarizations. An elementary cell includes a conducting plane and first and second transverse phase shifters, the first phase shifter is substantially parallel to a linear polarization and the second phase shifter is substantially parallel to the other linear polarization. The conducting plane is placed substantially parallel to the phase shifters. The antenna is applicable in particular for microwave applications requiring two transmission bands moreover subject to very low-cost production conditions.

Abstract: A method and apparatus for throughput compression for use in a videophone camera wherein an array of photosensitive cells is divided into odd and even lines and the cells of these cells are interlaced with each other and then the interlaced lines are coupled together such that during a first time interval the electric charges stored in the cells of the even lines are transferred to a plurality of first storage cells, then transferred to a plurality of corresponding second storage cells during a succeeding time interval and finally added in the second storage cells to the electrical charges in the corresponding cells of the odd lines of the cell array during a third time interval.

Abstract: A matrix for a gas discharge display panel, consisting of a plate, made of glass for example, comprising on each of its large faces, an array of parallel grooves; said two groove array are at right-angles to one another and are sufficiently deep for the matrix to be perforated from one side to the other, at the zones of intersection of said groove arrays.Such a matrix, arranged between two slabs, suitably separates the display cells from the electrical point of view, whilst still allowing them to communicate with one another this being an advantage where manufacture and "conditioning" of the panel are concerned.
