Abstract

L'invention porte sur des capteurs capacitifs utilisés pour détecter la force sur un produit transparent pour détecter et établir les caractéristiques d'un véhicule en cas de choc, ainsi que sur des capteurs capacitifs utilisés en combinaison avec un panneau conductif faisant office de couvercle pour coussin gonflable de sécurité et de tapis de sol pour les capteurs capacitifs. Ces derniers étant composés d'électrodes dont l'une d'elles peut être un revêtement conducteur. Les capteurs capacitifs peuvent être disposés sur un substrat et comprendre un capteur de référence. Les effets à long terme de la température sur la sortie du capteur sont compensés par un algorithme qui procède à une comparaison entre la sortie du capteur déterminé constante et la faible dérive de fréquence due aux effets de la température. L'humidité observée à la surface du produit transparent est distinguée de celle d'un objet placé à proximité en raison de la capacité captée. Un algorithme de détection du sommeil détecte le moment où le conducteur du véhicule est en train de s'endormir. Une mosaïque de capteurs capacitifs équipée d'un capteur circulaire emboîté et de capteurs en forme de L, comportant également un capteur fictif est utilisé sur le toit ouvrant d'un véhicule lorsque celui-ci en possède un, de manière à détecter la position de la tête de l'occupant.
