Abstract: L'invention concerne une étiquette (10, 300) piézo-électrique se présentant sous forme d'une carte. Cette étiquette (10, 300) comprend une première antenne (20) dipôle, un premier circuit (30) de redressement, un transformateur (40) piézo-électrique, un second circuit (50) de redressement et un circuit (60) répondeur. Pendant le fonctionnement, l'antenne (20) reçoit le rayonnement entrant et génère un signal Sa correspondant qui se propage vers le premier circuit (30), lequel le filtre et le démodule afin de générer un signal Sb. Ce signal Sb est appliqué au transformateur (40) afin d'exciter ce dernier. Le transformateur (40) augmente alors l'amplitude de tension du signal Sb, générant ainsi un signal Sc qui possède une amplitude de tension comparativement plus élevée, et qui est utilisé dans l'étiquette (10,300) pour générer un signal Sd servant à l'alimentation électrique du répondeur (60). Le répondeur (40) augmente la valeur de la tension afin de produire des tensions permettant de faire fonctionner les circuits électroniques actifs incorporés à l'étiquette (10, 300). Cette étiquette peut être portée par le personnel, et convient à l'implantation permanente dans des systèmes biologiques.

Abstract: L'invention porte sur un système optique de transmission présentant une structure supprimant efficacement la dispersion chromatique cumulée dans une ligne de transmission par fibre optique reliant un émetteur à un récepteur, et permettant par là des phototransmissions à grande capacité. Ledit système mesure et compense les variations de dispersion chromatique dans la ligne de transmission, supprimant par là les variations de la dispersion chromatique cumulée sur la totalité de la ligne de transmission. La variation de dispersion chromatique se calcule soit en suivant les variations de température de la ligne de transmission, soit en faisant se propager la lumière observée dans une ligne de transmission factice parallèle à la ligne de transmission réelle. D'autre part la compensation de la variation de dispersion chromatique s'obtient en décalant la longueur d'onde du signal de l'émetteur vers le haut ou vers le bas, ou en utilisant un compensateur de dispersion tel qu'une fibre optique à compensation de dispersion ou analogue.
