Abstract: A light device 1 for a motor vehicle comprising: at least one first aperture for air, and a first plug for the at least one first aperture, the first plug being movable between a ‘closed’ position and an ‘open’ position of the first aperture. The light device thus makes it possible to achieve: efficient ventilation, when the plug is in the open position, particularly when the vehicle is moving, and relative obstruction to the ingress of dust and liquids, when the plug is in the closed position, particularly when the vehicle is stationary.

Abstract: The precipitation measuring system is used for electronically measuring the amounts of rain, snow, hail or the like, with the use of a load cell. The system comprises a second frame mounted within a first frame. The second frame bears the collector and a load cell connects the second frame to the first frame. The load cell comprises a strain gauge bridge which is used to convert strain variations in the load cell into electrical conditions altering an electric current. These electrical variations correspond to weight variations occurring when the amount of precipitations in the collector varies and are then recorded by a recording device such as a computer. One advantage of the present invention is that the static and dynamic friction are eliminated, which greatly improves the precision and reliability of the system over the ones presently in operation. The calibration procedures are also simplified.
