Abstract
LA INVENCION ESTA RELACIONADA CON UN ELEMENTO DE SEGURIDAD PARA UN DISPOSITIVO ELECTRONICO ANTIRROBO DE ARTICULOS, COMPUESTO DE, AL MENOS, UN CIRCUITO IMPRESO EN FORMA DE ESPIRAL (2, 3) Y UN CAPACITOR CON UNA CAPA DIELECTRICA (4) SITUADA ENTRE AMBOS, O COMPUESTO DE DOS CIRCUITOS IMPRESOS EN FORMA DE ESPIRAL (2, 3) QUE SE DISPONEN, AL MENOS PARCIALMENTE, DE FORMA SOLAPADA A AMBOS LADOS DE LA CAPA DIELECTRICA (4) (CIRCUITO OSCILANTE DE RESONANCIA (6)). LA TAREA DE LA INVENCION SE BASA EN PROPONER UN CIRCUITO OSCILANTE DE RESONANCIA (6) CON PROBABILIDAD DE REACTIVACION REDUCIDA. LA TAREA SE RESUELVE, GRACIAS A QUE EN LA CAPA DIELECTRICA (4) SE PREVE, COMO MINIMO, UNA ZONA SELECCIONADA (8) (UN PUNTO DE ROTURA CONTROLADO) EN LA QUE, EN CASO DE UN SUMINISTRO DE ENERGIA SUFICIENTEMENTE ELEVADO A TRAVES DE UN CAMPO ALTERNATIVO MAGNETICO, SE CREA UN CORTOCIRCUITO ENTRE LAS PLACAS DEL CAPACITOR OPUESTAS O LOS CIRCUITOS IMPRESOS EN FORMA DE ESPIRAL (2, 3) Y GRACIAS A QUE LA ZONA SELECCIONADA (8) SE REFUERZA LOCALMENTE, EVITANDOSE UNA SUPRESION DEL CORTOCIRCUITO POR SOLICITACION MECANICA Y, POR LO TANTO, UNA REACTIVACION DEL ELEMENTO DE SEGURIDAD (6).
