Abstract

Cette invention concerne un support de communication sans contact permettant d'établir une communication sur une distance prédéterminée même en cas de superposition des supports sans contact. La sortie d'un circuit de résonance (60) relié électro-magnétiquement à un dispositif de communication externe est redressé par un circuit d'alimentation et extraite. La tension de sortie V est surveillée par un circuit de commande de commutation (61). Si la tension de sortie V dépasse un seuil Vth1, un élément de commutation (SW) s'enclenche. Si cette tension de sortie V continue d'augmenter, un élément commutateur d'alimentation (PSW) s'enclenche. Si la tension de sortie V tombe au-dessous du seuil Vth1, le commutateur (SW) se désenclenche. Lorsque les deux cartes à circuit intégré (6) utilisées sont superposées, l'élément de commutation (SW) d'une des cartes est enclenché alors que l'élément de commutation (SW) de l'autre carte est désenclenché. Dans cette situation, les deux cartes peuvent être utilisées pour la communication.
