Title (EN) CAPACITIVE RAIN SENSOR
(FR) DETECTEUR DE PLUIE CAPACITIF
Abstract:
(EN) The invention relates to capacitive rain sensors. The inventive rain sensors are placed on a window panel, comprise electrodes and conductors, which supply the latter and which are made of a conductive material. Inside the sensors, the electrodes are provided with dimensions and are arranged relative to another so that they simultaneously have a number of levels of sensitivity. The inventive rain sensors are primarily used on motor vehicle windshields.
(FR) La présente invention est relative aux détecteurs capacitifs de pluie. Les détecteurs de pluie selon l'invention disposés sur un vitrage, comprennent des électrodes et des conducteurs alimentant celles-ci, formés d'un matériau conducteur. Dans ces détecteurs les électrodes sont configurées en dimensions et en disposition les unes par rapport aux autres, de manière à présenter simultanément plusieurs niveaux de sensibilité. Les détecteurs de pluie selon l'invention sont utilisés notamment sur les pare-brise automobile.
