Abstract
MARCADOR CODIFICADO DESACTIVABLE Y SISTEMA Y METODO CORRESPONDIENTES DE VIGILANCIA DE ARTICULOS, TENIENDO EL MARCADOR UNO O VARIOS NUCLEOS DE MATERIAL MAGNETICO BLANDO, UNO O MAS ELEMENTOS ELECTRICAMENTE CONDUCTORES RODEANDO LOS NUCLEOS, PROVOCANDO LA GENERACION DE SEÑALES ARMONICAS DE FASE DESPLAZADA Y UNO O MAS ELEMENTOS SEPARADAMENTE IMANTABLES Y DE ELEVADA COERCITIVIDAD PARA DESACTIVAR EL MARCADOR. EL SISTEMA COMPRENDE MEDIOS DE GENERAR SEÑALES DE REFERENCIA EN UNA ZONA DE DETECCION, MARCADORES, MEDIOS PARA RECIBIR SEÑALES ARMONICAS GENERADAS POR LOS MARCADORES, MEDIOS PARA AJUSTAR LAS SEÑALES DE REFERENCIA, MEDIOS PARA DETERMINAR EL DESPLAZAMIENTO DE FASE ENTRE LAS SEÑALES DE REFERENCIA Y LAS SEÑALES ARMONICAS Y MEDIOS PARA GENERAR UNA SEÑAL DE CONTROL. EL METODO COMPRENDE EL USO DE LOS MARCADORES EN LA VIGILANCIA DE ARTICULOS. LA CONSTRUCCION DEL MARCADOR EVITA FALSAS ALARMAS POR ACUMULACION DE SEÑALES RESIDUALES, AUMENTANDO LA FIABILIDAD DEL SISTEMA.
