Abstract: The invention relates to a trim assembly (1) of a motor vehicle, comprising a passenger compartment mat (3) extending between a visible face (4) and a reverse face (5), the mat (3) comprising a side contour surface (6) that joins said faces, the assembly (1) comprising a soundproofing element (7a), which is designed to occupy the space (8a) comprised between a floor (9a) of the passenger compartment (2) of the vehicle and the reverse side (5) when the mat (3) is installed in the vehicle, the assembly (1) comprising at least one trim element (13) designed to at least partially conceal a side rail (10a) of the vehicle. The mat (3) is designed to be positioned in the passenger compartment (2) of the vehicle with the contour surface (6) positioned opposite at least a portion of the side rail (10a), the trim element (13) being designed to conceal, when it is installed on the side rail (10a), a portion of the visible face (4) of the mat (3).

Abstract: Disclosed is a motor drive device with tacho-generator that can be configured as a back-up motor. This device is designed for the driving of a movable element. It comprises an electrical rotor motor with supply coil, associated with a tachometrical sensor inducing an electrical current in at least one electrical coil, a regulator circuit controlling the speed and the position of the electrical motor as a function of the servo signal delivered by said electrical coil and applied to the supply coil. This device further comprises means to continue the driving of the movable element in the event of the malfunctioning of the electrical motor or of its electrical supply. These means to continue the driving of the movable element are constituted by a failure detection circuit which, in the event of failure, activates switching means to connect the electrical coil of the tachometrical sensor to an electrical supply source. Application: improvement of the safety of a motor drive mechanism.

Abstract: Disclosed is an airborne optoelectronic system using a facetted port. There is provision for compensation means in the form of two prisms with variable index, each formed by a lateral facet and a second facet forming a cavity, within which the refractive index is adjusted by the control of the internal gas pressure. The variation in the pressure with the cavity is achieved by following a control point value depending notably on the altitude of the carrier and the orientation of the line of sight. This results in eliminating the doubling of the image which occurs when there is no compensation when the altitude of the carrier varies and when the incident flux is distributed among the facets. The disclosed device can be applied to optoelectronic systems for warplanes, the flight altitudes of which may vary widely.

Abstract: This system enables the boresighting of the optical axes of a system comprising, for example: an infrared distance measuring device, a television camera, sensitive in the visible band, and a laser telemeter which does not emit radiation in the ranges of spectral sensitivity of the distance measuring device and of the camera. One embodiment includes:a collimated radiation source, associated with the laser;a wide-band collimator including, in its focal plane, a screen with holes cut out in it, constituting a reticle illuminated by an incandescent bulb, the surface of the screen being covered with glass micro-beads. The source associated with the laser forms a light spot on the screen, and this light spot is visible to the television camera. The holes form a reticle visible both to the television camera and to the distance measuring device. The distance measuring device determines the distance between the image of the reticle and a reference point on its image sensor.
