Title: Procede et dispositif d'essaimage de drones sur des trajectoires courbes autour d'un ou plusieurs points de reference
Inventor: FESLAND SYLVAIN
IPC: B64C39/02
Filed: 1995-04-13
Abstract: L'invention est relative au déploiement et à l'entretien d'une ceinture de drones autonomes (2) équipés de détecteurs d'alerte pour assurer la surveillance de l'environnement d'un ou plusieurs points sensibles (1). Elle concerne notamment les systèmes d'alerte antimissiles et antiaéronefs basse et très basse altitude pour des bâtiments de surface de la marine. Elle consiste à contrôler les trajectoires des drones uniquement au moyen de leur rayon de courbure pour lequel ils reçoivent une consigne depuis le ou les points de référence (1) codée par une fréquence d'un signal radioélectrique sensible à l'effet Doppler. Une modification de cette consigne de rayon de courbure en fonction du signal d'un capteur de proximité permet d'éviter tous problèmes de collision et de maintenir chaque drone à égale distance l'un de l'autre. Ce mode de contrôle s'avère particulièrement efficace tout en étant d'une grande simplicité.

Patent FR-2765620-A1 (FR)
Title: Operation of expansion chamber in low pollution IC engine
Inventor: NEGRE GUY
IPC: F02B27/00
Filed: 1997-07-02
Abstract: The engine has an aspiration and compression cylinder (1) and an independent expansion cylinder (4) for the exhaust. Pressure in the expansion cylinder is augmented by passing gas emerging from the main cylinder through a chamber divided into two. The chambers are separated by a high speed valve (2C) that abruptly connects one to the other, with the pressure difference generating an expansion wave which crosses the working chamber and creates a compression shock wave. The chamber contains a cathode (2H) that ionises the gas emerging from the main cylinder before it enters the working chamber to create electromagnetic waves which increase the intensity of the shock wave.

Title: Antitheft system for motor vehicles
Inventor: GARNAULT JOEL
IPC: B60R25/04
Filed: 1997-09-22
Abstract: The owner carries a transponder which can be detected within the vehicle to determine valid use of the vehicle. The antitheft system for a motor vehicle includes a processor which is capable of recognizing a main identifier which authorizes the deactivation of the vehicle immobilization system. It also includes a system capable of recognizing a secondary identifier which comprises a radio link with a transponder carried by the rightful user of the vehicle. This action does not require active operation by the user, but is carried out automatically at regular intervals during the operation of the vehicle. If the transponder replies as expected, then the vehicle may continue to be used, but if it fails to respond the vehicle immobilizer system is brought into action. This may act upon the vehicle indicators, the vehicle door locks and can simulate a vehicle breakdown.

The installation used to implement the process comprises: (a) a rolling cage having two spaced columns (11); (b) at least two superposed working rolls (12, 12') between the columns of the cage; (c) device for control of feed of the product (2) for rolling in a rolling nip (22) delimited by two arcs of contact (20, 20') of the product (2) with the two rolls, between an inlet and an outlet section of the rolling nip (22); tightening apparatus (17) for applying pressure on the rolls and the cage to regulate the gap between the working rolls (12, 12') corresponding to a desired reduction in thickness and to maintain the gap during the rolling pass by applying between the working rolls (12, 12') a rolling force that depends on the mechanical and physical characteristics of the cage and the product and the conditions of passage of the metal in the rolling nip, and determines a yielding effect for different elements of the cage tending to augment the gap; and (d) devices (31, 32) controlled by a calculation unit (4) comprising a calculator (40) associated with a mathematical model, to regulate the tightening apparatus. Before each pass the calculation unit (4) associated with the mathematical model (40) determines a predictable value of the contraction stress of the metal corresponding to the deformation to be realized in the considered pass by taking into account during rolling the microcrystalline structure of the metal constituting the rolling product (2). The rolling force to be applied in order to obtain the desired thickness reduction is calculated before each pass as a function of the predictable value of the contraction stress and its development during rolling.

Title: Multilevel floating gate memory cell for ROM units, comprising current comparator, polarization voltage generator, transistor and decoder
Inventor: GUEDJ MARC
IPC: G11C11/56
Filed: 1998-12-04
Abstract: The proposed memory circuit and the reading procedure are based on the utilization of the polarization voltage (VP) on the transistor gate equal to the voltage necessary to obtain a predetermined reference current (Iref) in the selected memory transistor (10) by comparing the current (Icell) in the transistor channel to the reference current (Iref). The decoding or reading of the memory stored data is carried out by decoding the polarization voltage (VP), by means of a decoder (CL) with output of high-value and low-value bits (MSb,LSb). The proposed memory cell comprises the current comparator (11), the polarization voltage generator (12) with output connected to the gate of transistor (10) of type e.g. MOS (metal-oxide-semiconductor) and the decoder (CL). The polarization voltage generator (12) is with inputs for the selection signal (LS) and the binary information of the current comparison.  The integrated memory circuit comprises a set of bit lines, a set of word lines, and a set of transistors with floating gates placed at intersections of the word lines and the bit lines. Each transistor with floating gate is for the memory of an electric state representing a stored data. The integrated memory circuit further comprises at least one comparator (11) for comparing the current (Icell) in the selected bit line to the reference current (Iref), a voltage generator (12) with output of the polarization voltage (VP) increasing until the current in the bit line is lower than the reference current, and a decoder (CL). The integrated memory circuit for e.g. 2-bit or 4-bit words, comprises loading transistors connected to the bit lines, and the transistor gates connected to an address decoder. The integrated memory circuit organized for higher bit value words comprises a set of matrices, each containing the bit and the word lines and the floating gate memory transistors, utilizing the same row decoder. At the time of reading only the bit line read is under voltage.
