Abstract

LA INVENCION SE REFIERE A UN DETECTOR CAPACITIVO CON UNA ANTENA PARA DETECTAR PEQUEÑOS CAMBIOS CAPACITIVOS EN UN CAMPO ELECTRICO O ELECTROMAGNETICO QUE RODEA LA ANTENA, Y PARTICULARMENTE A UN SISTEMA DE ALARMA QUE USA EL DETECTOR CAPACITIVO PARA GENERAR UNA SEÑAL DE ALARMA DESPUES DE LA DETECCION DE CAMBIOS CAPACITIVOS EN EL CAMPO ELECTRICO O ELECTROMAGNETICO GENERADO. EL DETECTOR ESTA REALIZADO CON UNA ANTENA CONECTADA A UNA CIRCUITERIA ELECTRONICA QUE GENERA UN CAMPO ELECTRICO ALREDEDOR DE LA ANTENA. LA CIRCUITERIA ELECTRONICA COMPRENDE MEDIOS GENERADORES PARA GENERAR UN CAMPO ELECTRICO O ELECTROMAGNETICO ALREDEDOR DE LA ANTENA, MEDIOS AJUSTABLES PARA CONSTRUIR UN CAMPO ELECTRICO EQUILIBRADO ALREDEDOR DE LA ANTENA, MEDIOS EQUILIBRADORES PARA MANTENER EL CAMPO ELECTRICO O ELECTROMAGNETICO GENERADO ALREDEDOR DE LA ANTENA EQUILIBRADO, MEDIOS FILTRADORES QUE EVITAN QUE EL DISPOSITIVO DETECTOR SEA AFECTADO POR LOS CAMBIOS EN LA TEMPERATURA O HUMEDAD, MEDIOS DE DETECCION QUE DETECTAN PEQUEÑOS CAMBIOS EN EL CAMPO ELECTRICO GENERADO ALREDEDOR DE LA ANTENA, Y MEDIOS INDICADORES QUE INDICA QUE SE HA PRODUCIDO UN CAMBIO EN EL CAMPO ELECTRICO GENERADO.
