Abstract: A lighting module comprising a light source of the LED type (not visible), a reflector with an elliptical reflective surface and a lens, the module being provided with means of quick-fastening to a mount. These means comprise a flange fitted with tabs (not visible) able to collaborate with corresponding notches of an orifice in the mount. This mounting allows the module to be fitted and removed very easily so that the light source or sources can be replaced, without disturbing the beam alignment. The invention also relates to the mount in question and to a corresponding headlamp.

Abstract: A vehicle headlight comprising at least one lighting module mounted on a support. The module comprises a base with a mounting surface inclined backward and toward the top of the headlight. The support comprises a corresponding mounting surface. Positioning means with sliders are provided on these surfaces so as to be able to extract the module and fit it by a translational movement in a direction contained within the plane of the mounting surfaces. The housing comprises a removable portion positioned in the extension of the module in the direction of translation of the positioning means with sliders. The wall of the housing comprises precuts on the circumference of the removable portion. This arrangement makes is possible to easily replace a bulky lighting module such as that of a headlight with style functions.

Abstract: A process, system and procedure of controls of the supply of a vehicle headlamp suitable to supply lighting in high beam function and/or low beam function, comprising the following stages for at least one of the low beam function and high beam functions: determining at least one driving parameter pertinent to the lighting of the vehicle, defining several lighting modes characterized by the value of this at least one parameter, attributing a supply mode of the headlamp to each lighting mode, and storing in memory the supply mode associated with each of the lighting modes.

Abstract: A headlamp for a motor vehicle, this headlamp comprising at least one optical module capable of emitting a plurality of light beams, including a low beam and at least one additional light beam. The optical module is equipped with a cover plate which can be moved between at least two positions, this movable cover plate being configured along a shaft mounted so as to rotate in the optical module and driven in rotation at least by a motor. The shaft comprises at least one first cut-off member configured as a double-edged cover plate providing an oblique cut-off for emission of the low beam, and at least one second cut-off member configured as a wall of substantially constant height, angularly offset relative to the first cut-off member and providing at least one substantially vertical cut-off line for emission of a high beam.

Abstract: A method and headlight adapted to supply power to a dual-mode automobile headlight light source able to provide either main beam mode lighting or dipped beam mode lighting, wherein the light source is supplied with electrical power at a first voltage when it is in main beam mode and at a second voltage when it is in dipped beam mode, the second voltage being lower than the first voltage.

Abstract: A device for correcting the faults of a sequence of images analyzed by an integrating matrix infrared sensor has a first part that determines a correction signal that is variable as a function of the temperature of the background of the images, equal to the product of a value representing the mean luminance of an image preceding the image undergoing correction, and a signal representing approximately the sensitivity of each cell of the sensor, constituted by the values of a video signal corresponding to an image analyzed in the course of a pre-calibration period; and a second part to determine a second correction signal, in storing the values of the first corrected video signal during a calibration period. An application of this device could be for the infrared cameras used in weapons systems.

Abstract: The disclosed device can be used to determine coordinates expressing the angular deviation between the direction in which a missile is located and a line of sight in which a target is located. The device comprises means to project and shift an image on a linear senor, in such a way that the field of acquisition of the homing device has a section, by a plane perpendicular to the line of sight, that is ring-shaped having a diameter corresponding to a wide field aperture at the moment when the missile is launched, so that the missile is definitely intercepted in the field of acquisition, and then having a diameter that is variable as a function of time in such a way that the ring follows the missile as and when it approaches the line of sight through the action of a remote control system or a directive beam system.

Abstract: A detector device for limiting background noise detected by a cooled infrared detector. In order to delimit the angle of view of the detector, the device comprises a reflecting deposit formed externally of the cooling device on one face of a transparent element interposed on the receiving path. The deposit can be located on the outer face of the window of the cooling device within which the detector is mounted on a cold table forming a spherical mirror. The complete assembly is optically combined so as to ensure that the radiation issuing from the detector outside the angle of view is returned to the detector.
