Abstract

LA INVENCION SE REFIERE A UN ELEMENTO (1) DE SEGURIDAD PARA ASEGURAMIENTO DE ARTICULOS DE FORMA ELECTRONICA, QUE SE COMPONE DE UN MATERIAL ANISOTROPO, MAGNETIZABLE DE FORMA CARACTERISTICA POR MEDIO DE UN EJE (XV) DE PREFERENCIA DE ALTA PERMEABILIDAD Y FUERZA COERCITIVA REDUCIDA (MATERIAL MAGNETICO BLANDO (3)), QUE MUESTRA LA FORMA DE UNA SUPERFICIE SUSPENDIDA DE MANERA CONJUNTA SENCILLA Y DE MODO QUE SE GENERA UNA SEÑAL (A(T) CARACTERISTICA EN LA COLOCACION DE UN CAMPO ALTERNATIVO MAGNETICO EXTERIOR, DONDE LA SEÑAL (A(T) ES MAXIMA, CUANDO EL EJE (XV) DE PREFERENCIA DEL ELEMENTO (1) DE SEGURIDAD ESTA DIRIGIDO DE FORMA PARALELA CON RESPECTO AL CAMPO DE CAMBIO MAGNETICO EXTERIOR (HEXT). LA INVENCION BASA SU OBJETIVO EN CONSEGUIR UN ELEMENTO (1) DE SEGURIDAD QUE SE COMPONE DE UNA SUPERFICIE NO SUSPENDIDA DE FORMA CONJUNTA SENCILLA, CUYA RELACION DE DETECCION ES COMPARABLE CON LA CUOTA DE DETECCION DE UN ELEMENTO (1) DE SEGURIDAD, QUE SE COMPONE DE UNA SUPERFICIE DE SUSPENSION CONJUNTA SENCILLA.EL OBJETIVO SE CONSIGUE DE TAL MODO, QUE EL ELEMENTO (1) DE SEGURIDAD MUESTRA AL MENOS UNA ZONA (2) ELEGIDA, EN DONDE SE MODIFICA EL FACTOR (N) DE DESMAGNETIZACION DEL MATERIAL (3) MAGNETICO BLANDO DE TAL MODO, QUE LA SEÑAL (A(T)) CARACTERISTICA MUESTRA UNA FORMA DE SEÑAL PREVIAMENTE DADA.
