Abstract

Un metodo para detectar una senal entre un indicador y un dispositivo electronico, para autorizar a un usuario el acceso a un dispositivo electronico. El metodo comprende las siguientes etapas: emitir una senal que contiene datos, detectar la senal con una pluralidad de antenas, y medir la fuerza de la senal detectada en cada una de las antenas. Si la fuerza maxima de senal detectada por cualquiera de las antenas se encuentra por encima del umbral operacional, el dispositivo electronico estara habilitado. Si la senal esta por encima del umbral operacional, la senal es comparada con una base de datos de codigo de usuario para autorizar al usuario el acceso al dispositivo electronico. El umbral operacional puede ser reducido para el conteo de cualquier variante de senal que pueda ocurrir despues de que el usuario ha sido autorizado al acceso o durante el acceso al dispositivo electronico.
