Abstract
EL TECLADO ACCIONADO CON LOS DEDOS, OPTOELECTRONICO, A SER UTILIZADOS EN APARATOS DE MEDIDA INDUSTRIALES ESTA CONCEBIDO CON RESPECTO A UNA RELACION UTILIZACION/SEÑAL PERTURBADORA OPTIMA Y UNA CAIDA DE INTENSIDAD LO MAS PEQUEÑA POSIBLE DEL EMISOR DE LUZ DE INFRARROJOS DURANTE LA DURACION DE SERVICIO DEL APARATO DE MEDIDA. LAS TECLAS DISPONEN PARA LA GENERACION DE UNA SEÑAL (N1,N2,3N) DE UTILIZACION DE ACCIONAMIENTO CORRESPONDIENTE UNA COBERTURA (1) TRANSPARENTE A LOS RAYOS INFRARROJOS, UN EMISOR (3) DE LUZ DE INFRARROJOS QUE RADIA DE FORMA ESTRECHA Y PRACTICAMENTE VERTICAL DISPUESTOS PARA CADA TECLA EN LA CARA (12) INTERIOR DE LA COBERTURA, UN RECEPTOR (4) DE LUZ DE INFRARROJOS ALINEADO CON LA COBERTURA, DISPUESTO DE FORMA SEPARADA CERCA Y CON ELLO EQUIPADO CON UN APANTALLADO (5) NO TRANSPARENTE A LOS RAYOS INFRARROJOS, ENCONTRANDOSE EL RECEPTOR DENTRO DE LA ZONA DE RADIACION PRINCIPAL DE LOS INFRARROJOS REFLECTADOS A PARTIR DE LA CARA EXTERIOR E INTERIOR DE LA COBERTURA, INCLUSO DE LOS RAYOS PROCEDENTES DE UN DEDO (2) CONTROLADO. UN CIRCUITO (8) DE ACCIONAMIENTO ABARCA PARA CADA TECLA UN CIRCUITO (15, 25,35) DE DETECCION Y CONTROL PROPIO, QUE PARA LA ALIMENTACION DEL EMISOR (13,23,33) DE LUZ GENERA UN IMPULSO (SI1, SI2, SI3) DE CONTROL CON UNA RELACION PAUSA-IMPULSO MENOR DE 1 : 1, Y PARA TODAS LAS TECLAS SE DISPONE DE UN CIRCUITO (18) DE PREGUNTA CONJUNTA, QUE CONTROLA TODOS LOS CIRCUITOS (15,25,35) DE DETECCION Y CONTROL CON UN POLO (SN) DE UN INTERRUPTOR (19) DE CORRIENTE UNIDO CON UNA FUENTE DE TENSION DE SERVICIO.
