Abstract

SISTEMAS DE DETECCION DE HURTOS MEDIANTE MARCADORES MAGNETICOS, LOS CUALES RESPONDEN A LA PRESENCIA DE UN ARTICULO DENTRO DE UNA ZONA DE INTERROGACION. CONSTAN DE UN MEDIO QUE DEFINE UNA ZONA DE INTERROGACION; DE UN MEDIO QUE GENERA UN CAMPO MAGNETICO DE DICHA ZONA DE INTEROGACION; DE UN MARCADOR FIJADO A UN ARTICULO DESTOINADO A PASAR A TRAVES DE LA MENCIONADA ZONA DE INTERROGACION, ESTANDO FORMADO EL MARCADOR POR UNA TIRA DUCTIL ALARGADA DE METAL FERROMAGNETICO AMORFO, CAPAZ DE PRODUCIR CAMPOS MAGNETICOS A FRECUENCIAS QUE SON ARMONICAS DE LA FRECUENCIA DE UN CAMPO MAGNETICO INCIDENTE; Y DE UN DETECTOR PARA DETECTAR VARIACIONES DE CAMPO MAGNETICO A TONALIDADES ESCOGIDAS DE DICHOS ARMONICOS.
