The present invention relates to an electrooptic method of signal processing, characterized in that it comprises the steps consisting in: providing at least one semiconductor component consisting at least of a substrate (10) and of a superposed assembly comprising at least one guiding layer (14) and applying, to the guiding layer (14), optical radiation at a wavelength and at an angle of incidence chosen in such a way that said assembly has, at this wavelength and at this angle of incidence, a s...

In a system for the regulation of information trains for packet switches, there is provided one queue per path in each input module liable to be driven by an arbitrator placed in each of the output modules bearing these channels.

The invention relates a printed bi-polarization acrial comprising first, second and third superimposed substrate lates (1, 2. 3); a first metal deposit (4), situated on the external face of said first substrate plate (1) which defines at least one first radiating element (5, 6) of the dipole type, in the form of a T, the horizontal bar of said T being constituted by two radiating lateral strands separated by a coupling slit; a first power supply line (7) pursuant to a first polarization, situate...

A system for acquiring and processing signals for controlling a device or a process has inputs receiving analog signals supplied by sensors and which are processed in order to send to the device control signals configured in accordance with a predetermined communication protocol. The system includes a screen and a keypad for accessing and modifying control signal configuration parameters. One application of the system is to controlling devices producing sound effects added to or applied to the s...

In order to depict a set of paths which are available for transporting a stream from a first node (1) to a second node (6) of the network, one or more perimeters are placed around each symbol designating a departure node of an elementary link of a path of the set, and a respective flag is placed at the intersection between each arc designating an elementary link of the set of paths and a perimeter surrounding the symbol designating the departure node of said elementary link. This depiction techn...

The present invention relates to an optical component of the waveguide array spectrograph type, the component comprising an inlet coupler and an outlet coupler between which said array extends, and including optical channels constituting inlets and outlets for the inlet and outlet couplers, the component being suitable for multiplexing and/or demultiplexing two optical signals of different wavelengths conveyed by two channels of the same coupler, wherein the waveguides of the array have lengths ...

The network allows communications at various bit rates, with signals transmitted in successive frames each divided into elementary timeslots which can be used for different communications. A frequency band is allocated to communications between base stations of a group of cells and mobile stations. This band is subdivided into blocks of width 2.sup.M-1.times.B.sub.0, where B.sub.0 is a predefined spectral width and M an integer greater than 1 chosen as a function of a maximum communication bit r...

A method which includes, prior to depositing the encapsulating silicon layer: A) depositing on the Si.sub.1-x Ge.sub.x layer a thin film of amorphous or polycrystalline silicon, then in treating said silicon film with gas nitric oxide at a temperature between 450 to 600.degree. C. and at a pressure level of 10.sup.4 to 10.sup.5 Pa to obtain a thin nitrided silicon film; or B) depositing on the Si.sub.1-x Ge.sub.x layer a thin film of amorphous or polycrystalline silicon and oxidizing the silicon...

Disclosed is a method for the detection of the relative depth of two neighboring regions in relative motion with respect to each other in two images obtained from different shots of a scene, in order to know the composition of the scene. The method consists in carrying out a spatial segmentation of one of the images, called a reference image; a local estimation of the motion between the two images, the resultant vector field of which is called local motion; a determining of the motion estimation...

In a device for placing a structural element in a cable installation conduit in order to sub-divide it, the structural element has a width close to the size of the internal perimeter of the conduit and comprises a plate surmounted by ribs. The device comprises a hot air inlet designed to soften the plate of the structural element; an external cylinder whose diameter is identical to that of the conduit, the cylinder comprising a shaping cone at one end in order to enable the softened structural e...
