Abstract

Sistema para vigilar artículos protegidos electromagnéticamente en n zonas de vigilancia, indicando n el número de zonas de vigilancia situadas juntas y siendo mayor o igual a 2, estando definida cada una de las n zonas de vigilancia por dos dispositivos emisores/receptores que están dispuestos a ambos lados de la zona de vigilancia y presentando cada dispositivo emisor como mínimo una bobina emisora y cada dispositivo receptor m bobinas receptoras, indicando m el número de bobinas receptoras y siendo como mínimo igual a 1, caracterizado porque hay previsto un dispositivo de conexión (10) que reduce las salidas de los 2n dispositivos receptores (4) a n salidas.
