Abstract

UN DISPOSITIVO DE POLARIZACION CINESCOPICA AUTOMATICA (AKB) EMBEBIDA EN UN CIRCUITO INTEGRADO (IC) (500) INCLUYE LA CIRCUITERIA (520) PARA GENERAR UNA SEÑAL TEMPORIZANTE PULSO DE MUESTRA) DURANTE UN INTERVALO DE TEST AKB, LA CIRCUITERIA (510,530) PARA GENERAR UNA SEÑAL DE TEST (MUESTRA I) EN RESPUESTA A LA SEÑAL TEMPORIZANTE, Y LA CIRCUITERIA (SW2) QUE INCLUYE UN TERMINAL DE SALIDA (SALIDA VIDEO) PARA ACOPLAR LA SEÑAL DE TEST AL CINESCOPIO (300). LA AKB IC TAMBIEN INCLUYE UN TERMINAL DE ENTRADA (ENTRADA VIDEO) Y UN ELEMENTO INTERRUPTOR (SW1) ACOPLADO ENTRE EL TERMINAL DE ENTRADA Y EL TERMINAL DE SALIDA Y SENSIBLE A LA SEÑAL TEMPORIZANTE PARA SELECTIVAMENTE DESACOPLAR EL TERMINAL DE ENTRADA DEL TERMINAL DE SALIDA. EN UN SISTEMA DE TELEVISION QUE INCLUYE UNA RED DE POLARIZACION (400) LA CUAL ESTA ACOPLADA A LA SALIDA DE LA FUENTE DE SEÑAL DE VIDEO (100) Y QUE AL CINESCOPIO A SER CORTADO DURANTE EL INTERVALO DE TEST AKB, EL TERMINAL DE ENTRADA DE LA AKB IC ESTA ACOPLADO AL TERMINAL DE SALIDA DE LA FUENTE DE SEÑAL DE VIDEO. ESTO PERMITE A LA RED DE POLARIZACION A DESACOPLARSE DEL DISPOSITIVO DE PANTALLA DURANTE EL INTERVALO DE TEST AKB, POR LO CUAL PREVENIR A LA RED DE POLARIZACION DE AFECTAR LA OPERACION AKB. ALTERNATIVAMENTE, EN UN SISTEMA DE TELEVISION QUE NO INCLUYE UNA RED DE POLARIZACION QUE EVITE AL CINESCOPIO DE SER CORTADO DURANTE EL INTERVALO DE TEST AKB, EL TERMINAL DE SALIDA DE LA AKB IC ES DIRECTAMENTE ACOPLADO AL TERMINAL DE SALIDA DE LA FUENTE DE SEÑAL DE VIDEO
