Abstract: The invention relates to a lighting and/or signaling device including an electroluminescent diode and a lightguide adapted to convey the light from the diode and also means for securing the diode relative to an end of the lightguide to ensure the position of an inlet face of the guide opposite the diode. The lightguide carries male securing means adapted to interact with female securing means carried by a plastics component carrying the electroluminescent diode. The plastics component further includes electric circuits produced directly on the plastics of this component in immediate proximity to the diode.

Abstract: A lighting and/or signaling device comprising a plurality of light-emitting diodes secured to a support made of plastic which has at least one three-dimensional zone in the form of a staircase made up of successive treads and risers in substantially perpendicular planes, each of the diodes being fixed respectively to one of the treads of the support, the diodes being powered by conductive metallic tracks. The conducting tracks are formed by thicknesses of metal that differ according to whether the tracks extend along the treads or along the risers, the tracks arranged on a tread being produced by a thickness of metal encrusted into the volume of the plastic support, in housings formed in the thickness of the tread.

Abstract: A valve for a combustion engine air intake circuit, where the valve includes a main pipe and a bypass duct with upstream and downstream ends opening into the main pipe. The valve also includes a heating member that is positioned in the bypass duct and a shut-off member mounted such that it can move between a first position in which airflow can pass through the main pipe and a second position in which airflow can pass through the bypass duct.

Abstract: Device for air intake of a heat engine including: a main circulation system (105) which connects a supercharging apparatus (106) or an air intake manifold (107) which incorporates a heat exchanger (108), a bypass system (109) linked to the main circulation system along the exchanger, the bypass system incorporating a heating apparatus (29), a circuit selection device mounted between the main circulation system and the bypass system to channel at least some of the air into one or the other system.
