Abstract: A method for enabling an apparatus (15) to operate only after detecting with receiver elements (11) located proximate to the apparatus, a signal transmitted by portable transmitted elements (1), which consists in no longer taking into account detection by the receiver means (11) of the signal transmitted by the transmitting elements (1), after activating presence sensing elements (22) provided proximate to the apparatus, or integrated in the apparatus. Once activated, the presence sensing elements (22) neutralize the transmitter/receiver device (1, 11) and the apparatus can operate normally without being perturbed by possible statics or accidental losses of signal. The inventive method and device are applicable to an antitheft safety device for a motor vehicle.

Abstract: A receiving case for a video unit includes an electronic console (2) and an associated independent screen (3), which case includes stowing sections (4, 5) suited to accommodate respectively the electronic console (2) and the associated screen (3), and also includes holding parts to hold the external face of the stowing section (5) suited to accommodate the screen (3) tight against the rear face of the head-rest section of a seat. These holding parts form a fastening system, for instance in the form of single block head-rest protective cover (20).

Abstract: The invention concerns a case (1) consisting of two storage parts (4, 5) mutually secured via a hinge system and provided with means (7) for being removably locked in closed position, that is when they are in contact with each other through their peripheral edge. One of the storage parts (5) is adapted to receive detachably a video screen (3) with its front face visible when the case is in opened position, the other storage part (4) is adapted to receive the electronic console (2) associated with said screen (3) likewise detachably (said console (2) being for example in the form of a DVD video player or a game console). The case further comprises: at least one powering plug-in connection terminating in two removable plug connectors on the screen (3) and electronic console (2), and an internal wiring system provided with detachable plugs for audio-video connection between said electronic console (2) and said associated video screen (3).

Abstract: Anti-theft security devices for a motor vehicle, comprise portable transmitting elements, of a receiving module on board the vehicle and of elements controlling a system for interrupting at least one circuit required for operating the vehicle (ignition circuit engine, fuel intake circuit or other . . . ) when the distance between the transmitting elements and the receiving elements exceeds a certain value. The method for managing the operation of such a device consists, when resetting the affected circuit(s), following an interruption relative to accidental signal loss, in performing this resetting only very gradually.

Abstract: This invention concerns a receiving case for a video unit comprising an electronic console (2) and an associated independent screen (3), which case comprises stowing sections (4, 5) suited to accommodate respectively the electronic console (2) and the associated screen (3), and also comprises means enabling to hold the external face of the stowing section (5) suited to accommodate the screen (3) tight against the rear face of the head-rest section of a seat.

Abstract: This invention concerns a video unit, intended for a seat, with a video set comprising an electronic console (5), such as a video reader or a play station, and an associated independent screen (7), which unit comprises moreover—a connection means (11) intended for the electric supply of said video unit, and—an interconnection means (12) for the audio-video link between said console and said screen.

Abstract: An emergency braking warning device includes a printed circuit (1) whereon are implanted a voltage regulator/stabiliser assembly (3), a two-way digital inertia sensor (5), a microprocessor (6) and power control elements (10, 11). The voltage regulator/stabiliser assembly (3) is connected to the vehicle battery and powers the two-way digital inertia sensor (5) and the microprocessor (6). The microprocessor (6) is adapted to manage data coming from the digital sensor (5) and it is connected to the power control elements (10, 11) interposed on the circuits of the right (8) and left (9) flashers, to enable the triggering of the flashers (8, 9) when the programmed braking threshold is exceeded.
