Abstract: front page image
(EN)An implantable receiver inductor here are two coils (Coil 1 and Coil2, Fig. 3) and each coil comprises two diametrically-opposed quadrant-shaped parts. Because each coil is arranged across opposed quadrants, a change in orientation will have the same effect in both coils. Therefore, only a single channel need be monitored. By arranging the two receiver coils so that each coil is spread across different physical locations, the varying effect of relative displacement between transmitter and receiver is neutralised such that if a certain displacement results in an increased signal on one channel, then there will also be a corresponding increased signal on the second channel. Similarly, a displacement leading to a decreased signal on one channel will also result in a similar decrease in the signal on the second channel. Hence, by monitoring and controlling a single channel, a second channel can also be monitored and controlled indirectly without any further resources required.
(FR)L'invention concerne une bobine d'induction de réception implantable constituée de deux bobines (bobine 1 et bobine 2, figure 3), chaque bobine comprenant deux pièces en quadrant diamétralement opposées. Chaque bobine étant disposée sur des quadrants opposés, un changement d'orientation produira le même effet dans les deux bobines. En conséquence, on ne doit surveiller qu'un canal. En disposant les deux bobines de réception de façon que chacune soit étalée sur des emplacements physiques différents, on neutralise l'effet variable du déplacement relatif entre l'émetteur et le récepteur, ainsi, si un déplacement donné produit un signal accru sur un canal, un signal accru correspondant se produira également sur le second canal. De même, un déplacement donnant lieu à un signal réduit sur un canal, produira également une diminution analogue du signal sur le second canal. En conséquence, en surveillant et en régulant un seul canal, on peut également surveiller et réguler indirectement un second canal sans faire appel à d'autres ressources supplémentaires.
