Abstract

SE DESCRIBE UN LECTOR QUE PERMITE INTERROGAR UNA ETIQUETA MAGNETICA, POR EJEMPLO PARA LEER LOS DATOS ALMACENADOS EN LA TARJETA. EL LECTOR COMPRENDE UN DISPOSITIVO GENERADOR DE CAMPO, CAMPO MAGNETICO PRODUCIDO QUE DEFINE UNA ZONA DE INTERROGACION, EN DONDE EL DISPOSITIVO GENERADOR DE CAMPO COMPRENDE: (A) MEDIOS PARA GENERAR UN CAMPO MAGNETICO; (B) UNA BOBINA DE TRANSMISION PARA TRANSMITIR UNA SEÑAL ELECTROMAGNETICA DE INTERROGACION A LA ZONA DE INTERROGACION DE MANERA QUE ACTUE CONJUNTAMENTE CON UNA ETIQUETA MAGNETICA, CUANDO ESTA PRESENTE EN ESA ZONA DE INTERROGACION; Y (C) AL MENOS UNA BOBINA RECEPTORA PARA RECIBIR UNA SEÑAL ELECTROMAGNETICA GENERADA POR UNA ETIQUETA EN RESPUESTA A DICHA SEÑAL DE INTERROGACION Y EL CAMPO MAGNETICO PRODUCIDO POR ESTE MEDIO GENERADOR DE CAMPO MAGNETICO. EL MEDIO GENERADOR DE CAMPO MAGNETICO PUEDE ADOPTAR LA FORMA DE UN PAR DE CILINDROS HUECOS, QUE PROPORCIONAN UN LECTOR EN BUCLE, O PUEDE CONSISTIR EN UN IMAN PLANO QUE DA LUGAR A UN LECTOR DE "PASO LATERAL".
