Abstract

Patente de Invenção: <B>"CIRCUITO RESSONANTE QUE PODE SER DESATIVADO"<D>. Uma marca ressonante (68) utilizada com um sistema de vigilância eletrónica de artigos para detectar a marca dentro de uma área vigiada utilizando energia eletromagnética em uma freq³ência de detecção predeterminada inclui um circuito ressonante (66, 68) capaz de ressoar na freq³ência de detecção prederminada. O circuito ressonante (66, 68) inclui um indutor (66) formado pelo menos em parte em uma superfície de um substrato dielétrico da marca (58). O indutor (66)'; e formado com uma descontinuidade ou abertura (74) causando um circuito elétrico aberto. O circuito elétrico aberto é fechado com um fusível (36) seguro próximo a abertura (74) e ligado por fio elétrico (40, 42) com as partes do indutor (66) próximas a abertura
