Abstract
Un sistema y método que comunican señales entre una unidad portátil y un sistema de comunicaciones. El dispositivo portátil se comunica con una unidad base usando un acoplamiento inductivo. La unidad base se comunica con un sistema más amplio de comunicaciones tales como una red telefonica. los transductores multiples ortogonalmente dispuestos son usados en la unidad base para proporcionar un campo magnético más completo y para prevenir los nulos de inductancia mutua que están presentes en un campo magnético. El uso de acoplamientos inductivos de corto alcance reduce los requisitos de alimentacion y limita la interferencia con otras fuentes. El acoplamiento inductivo también puede ser usado para recargar una batería en el dispositivo portátil.
