Abstract

Z ESTA CONECTADA A UN INDICADOR DE PRESENCIA Y A UN INDICADOR DE DESACTIVACION, ESTANDO DICHO DETECTOR CONECTADO A UN DISPOSITIVO DE DESACTIVACION PROVISTO DE UNA ANTENA TRANSMISORA.EL ROTULO POSEE CIERTAS PORCIONES PREDETERMINADAS DE DICHAS AREAS CONDUCTORAS SEPARADAS POR MATERIAL DIELECTRICO Y AL MENOS, ALGUNAS DE ESAS PORCIONES ESTAN UBICADAS FORMANDO UN TRAYECTO DE MENOR RESISTENCIA A TRAVES DE DICHO MATERIAL DIELECTRICO, QUE EN RESPUESTA A UN CAMPO ELECTROMAGNETICO A UNA FRECUENCIA DE DESACTIVACION DE ENERGIA SUFICIENTE ES DESTRUIDA MODIFICANDOSE LA FRECUENCIA DE RESONANCIA DEL CIRCUITO SINTONIZADO DE DICHO ROTULO EN LA FRECUENCIA DE DETECCIONZ IS CONNECTED TO A PRESENCE INDICATOR AND A DEACTIVATION INDICATOR, WITH SUCH DETECTOR CONNECTED TO A DEACTIVATION DEVICE PROVIDED WITH A TRANSMITTER ANTENNA. PORTIONS ARE LOCATED FORMING A LESS RESISTANCE JOURNEY THROUGH SUCH DIELECTRIC MATERIAL, WHICH IN RESPONSE TO A ELECTROMAGNETIC FIELD OF A FREQUENCY OF DEACTIVATION OF ENERGY IS DESTROYED BY THE CIRCUIT-BASED RESIDENCE FREQUENCY,
