Abstract

Una disposición para desactivar una baliza de vigilancia electrónica colocada en un artículo, comprendiendo la disposición: (a) un carro destinado a mover al menos un imán entre una primera posición y una segunda posición con relación al artículo; (b) al menos un primer imán transportado por el carro a una posición alineada con relación a una posición esperada de la baliza y que genera un campo magnético de suficiente intensidad para desactivar la baliza cuando el carro se mueve con relación al artículo; y (c) un motor operativamente acoplado al carro para moverlo entre la primera posición y la segunda posición para desactivar la baliza.
