Abstract
L'invention concerne un procédé et un système permettant de mesurer une distance depuis une substance piézo-électrique (10): on transmet une impulsion électromagnétique (14) à la substance de manière à engendrer en réponse une impulsion acoustique (15). Cette impulsion est détectée par un capteur acoustique (12) déplacé par rapport à la substance selon une distance inconnue, et l'on mesure l'intervalle de temps entre l'établissement de l'impulsion électromagnétique et la réception de l'impulsion acoustique. La distance entre la substance et le capteur acoustique est calculée en multipliant l'intervalle de temps mesuré par la vitesse du son, qui est connue. Si l'on frappe la surface de la substance piézo-électrique contre une surface, il est possible de déceler une caractéristique d'écho modifiée de l'impulsion acoustique. Cela permet d'actionner l'un des différents commutateurs à détecter. Avec plusieurs capteurs, il est possible d'évaluer la position spatiale du commutateur, et donc d'identifier tel ou tel commutateur spécifique sur un clavier d'ordinateur conçu pour être utilisé avec un ordinateur mais non relié physiquement à un ordinateur.
