Abstract

SE DESCRIBE UN CIRCUITO DE CONTROL PARA REGISTRAR LA ACTUACION DE UNA TECLA OPTICA, QUE LLEVA UN DIODO FOTOSENSIBLE QUE TRABAJA EN CIRCUITO ABIERTO COMO UN SENSOR DE ACTIVACION DE LA TECLA. UN CIRCUITO MICROPROCESADOR VIGILA LA TENSION EN VACIO DEL DIODO PARA DISTINGUIR UNA ACTIVACION DE LA TECLA OPTICA DE LAS VARIACIONES DE BRILLO DE LA LUZ AMBIENTAL. LA INVENCION SE CARACTERIZA POR UN PROCESO DE CONVERSION TENSION-TIEMPO FACILMENTE REALIZABLE PARA VIGILAR LA TENSION EN VACIO. PARA ESTE FIN HAY UN CONDENSADOR CONECTADO AL DIODO QUE ADOPTA UN ESTADO DE ACCIONAMIENTO EN CARGA CORRESPONDIENTE A LA TENSION DE VACIO DEL DIODO Y QUE PUEDE DESCARGAR PASANDO A UN ESTADO DE FUNCIONAMIENTO DE DESCARGA A TRAVES DE UNA RESISTENCIA DE DESCARGA, PRESENTANDO EL CIRCUITO MICROPROCESADOR UNA PUERTA DE ENTRADA DE ALTA RESISTENCIA CONECTADA AL CONDENSADOR PARA VIGILAR LA DESCARGA DEL CONDENSADOR, Y DETERMINA, COMO MEDIDA DE LA TENSION EN VACIO, EL TIEMPO QUE TRANSCURRE HASTA QUE LA TENSION EN LA PUERTA DE ENTRADA DURANTE EL PROCESO DE DESCARGA DEL CONDENSADOR ALCANZA UN UMBRAL DE CONMUTACION PREDETERMINADO DE LA PUERTA DE ENTRADA.
