Abstract

SEGUN LA INVENCION, UN MENSAJE DIGITAL CODIFICADO SIRVE PARA LA MODULACION DE UNA TENSION DE ALIMENTACION DE TUBOS FLUORESCENTES (5). LA MODULACION SE EFECTUA, BIEN EN FRECUENCIA, BIEN EN DURACION DE IMPULSOS SINCRONIZADOS EN LA RED. EN EL PRIMER CASO, SE DIVIDE UNA TENSION CONTINUA Y SE ALIMENTA A LOS TUBOS FLUORESCENTES (5) CON ESTA TENSION, VARIANDO LA FRECUENCIA DE DIVISION DE SENCILLA A DOBLE SEGUN EL ESTADO LOGICO DE LAS SEÑALES QUE CONSTITUYEN EL MENSAJE. EN EL SEGUNDO CASO, SE APLICA A LOS TUBOS FLUORESCENTES (5) SEMIALTERNANCIAS A LA FRECUENCIA DOBLE DE LA RED, SINCRONIZADAMENTE CON EL SEMIPERIODO DE LA FRECUENCIA DE RED, PARA UN PRIMER ESTADO LOGICO Y DESFASADAS PARA UN SEGUNDO ESTADO LOGICO. EL RECEPTOR ES UNA ETIQUETA ELECTRONICA (7) QUE COMPRENDE UNA CELULA FOTOELECTRICA (70), UN DECODIFICADOR, UN MICROCONTROLADOR Y UNA VISUALIZACION (71). TIENE APLICACION CONCRETA EN LA PUESTA AL DIA DE ETIQUETAS ELECTRONICAS EN UN PUNTO DE VENTA.
