Abstract: A method for detecting a message provided with a preamble with a number of pulses in a signal sent by an interrogator or a transponder in mode S, said method including a step for decomposition of said signal into an amplitude signal and into a complex phase signal, a step for detection of said preamble by correlating the amplitude signal with a replica signal of the expected pulses, and a phase control step executed by adding together the samples of the phase signal for the duration of the pulses of said preamble and by comparing the sum obtained with a threshold. The method may include a step for time synchronization by correlation of the complex phase signal with a reference sequence formed by one or more known bits before the decoding of the data. The method applies notably to the decoding of interrogation messages borne by low-power signals.

Abstract: System and method making it possible to operate in an interrogator mode and/or in a passive listening mode wherein it comprises in combination at least the following elements: an antenna (6) having a given aperture sector, a control means (31) making it possible to toggle the system into a first interrogator operating mode using a first given angle sector or into a second passive listening operating mode using a second angle sector of greater value than the first, means (23) making it possible to add together the signals received on the sum pathway and on the difference pathway of the antenna in the case of the passive listening operating mode.

Abstract: The present invention includes a method for identifying a facility on the ground or at sea, the method being implemented on an airborne responder linked to at least two antennas, the method including a step of choosing a first transmission antenna and a step of transmitting an interrogation message from the chosen antenna. The method further includes testing whether a response has been received by the responder, and, if at least one response signal is received by at least one of the antennas, choosing a transmission antenna as a function of the response signal or signals received. If no response message is received, a different transmission antenna is chosen from the antenna that transmitted the last interrogation message. The method is repeated from the step of transmitting the interrogation message.

Abstract: A method for the decoding of a signal in an interrogation/response type of communications system, the received signal being formed by a video signal and a signal containing the data, wherein the method comprises at least the following steps: 1) transposing the received data signal to an intermediate frequency Fl to obtain the signal Sdh(Fl), Sdb(Fl), 2) converting the intermediate frequency analog signal into a digital signal, 3) sampling the digital signal Sdh(Fl), Sdb(Fl) at a given frequency Fe to obtain the signal Seh, Seb, 4) transmitting the sampled signal Seh, Seb as well as the video signal Svh, Svb to a processing step so as to determine the initially received signal. The method can be applied to the demodulation of MSK, FSK, DPSK type waveforms.

Abstract: The invention relates to a pulse-modulated source with adjustable parameters and to its use in an IFF or secondary radar emitting assembly. The architecture of currently used IFF emitting assemblies is such that there is a limit to the possible reduction in the space requirement of such equipment, and this limit is soon reached. Furthermore, the precision in terms of frequency remains coarse and the number of IFF emitting modes is very small. A programmable source of pulse trains on an intermediate frequency is disclosed.

Abstract: The separating valve is intended for discharging the liquid phase of a two-phase fluid. It comprises a seating and a valve member, the latter being actuated to open by a float at the end of a first arm of a lever, whose other arm comprises a cam which engages in a neck of the shank of the valve member. The seating comprises a port at the center of a flat face from which projects a sleeve for guiding the shank of the valve member. Directed towards the flat face, the valve member comprises a flat plate from which there projects a truncated conical valve needle. Between seating and valve member there is defined an annular space communicating by three passageways with the chamber for receiving the liquid phase: one passageway which is an extension of a slot where the lever arm fits, and two passageways along a diameter perpendicular to the slot and tangential to the flat face.

Abstract: An improved roller bearing assembly of the type comprising an inner race having a cylindrical riding track; an outer race coaxial with the inner race, having an inner cylindrical riding track facing the outer riding track of the inner race; and a series of rollers mounted between the riding tracks. This roller bearing assembly is improved in that each of its rollers has at least two cylindrical riding surfaces of different radii, the cylindrical riding surface of longer radius exclusively contacting the outer race riding track while the cylindrical riding surface of smaller radii exclusively contacts the inner race riding track. The radius of the riding track of the outer race equals the sum of the radius of the riding track of the inner race plus the longer and smaller radii of the riding surfaces of one roller. The ratio of the radius of the riding track of the outer race over the radius of the riding track of the inner race equals the ratio of the longer radius over the shorter radius.
