Abstract

APARATO PARA ENTREGAR ENERGIA Y COMUNICARSE CON UN DISPOSITIVO DE ALMACENAMIENTO DE DATOS (4), P.E. UN FICHERO, QUE INCLUYE DE UNA FORMA SIN CONTACTO UN CIRCUITO RESONANTE (6) DISPUESTO PARA ACOPLAMIENTO INDUCTIVO CON EL DISPOSITIVO. LOS VALORES DE LOS COMPONENTES SE SELECCIONAN PARA OBTENER UNA TRANSFERENCIA DE ENERGIA CONSTANTE CUBRIENDO EL RANGO POSIBLE DE DISTANCIAS ENTRE LAS INDUCTANCIAS (36, 8). LAS COMUNICACIONES DESDE EL DISPOSITIVO RESULTAN EN CAMBIOS EN LA IMPEDANCIA NO EFECTIVA QUE SE DETECTAN POR LA DETECCION DE LOS CAMBIOS EN LA CORRIENTE DEL CIRCUITO RESONANTE. LA ENERGIA TRANSMITIDA POR EL CIRCUITO RESONANTE SE LIMITA PARA PREVENIR QUE ENERGIA EXCESIVA DAÑE LOS DISPOSITIVOS CUYAS CARACTERISTICAS SEAN TALES QUE PUEDAN SER AFECTADAS POR LOS NIVELES DE ENERGIA MAS ALTOS. LOS DISPOSITIVOS QUE REQUIEREN LOS NIVELES DE ENERGIA MAS ALTOS PUEDEN ENVIAR UNA SEÑAL QUE RESULTE EN QUE SE EVITE EL LIMITE.
