Abstract

L'invention concerne un indicateur de position. Il comprend deux parties, dont la première comporte deux surfaces parallèles opposées et dont la seconde comporte deux surfaces parallèles setendant chacune au voisinage immédiat de l'une des surfaces de la première partie et parallèlement à cette surface, une bobine principale etant fixée sur au moins l'une des surfaces de la première partie et au moins une bobine supplémentaire étant fixée sur chacune des surfaces de la seconde partie, les deux parties de l'appareil étant montées de manière pouvoir être déplacées l'une par rapport à l'autre pour provoquer une translation des bobines supplémentaires le long d'un chemin prédéterminé par rapport à bobine principale, et le couplage inductif entre chaque bobine supplémentaire et la bobine principale étant fonction de la position relative des deux parties de l'appareil.
