Abstract

ESTA INVENCION EXPONE UN LECTOR DE SEÑAL MEJORADO PARA LEER SEÑALES DE EMISORES RECEPTORES SITUADOS SOBRE OBJETOS MOVILES TAL COMO BARCOS CONTENEDORES, AUTOMOVILES O VAGONES DE FERROCARRIL. EL LECTOR ENVIA FUERA UNA SEÑAL CONTINUA, QUE ES MODIFICADA POR LA INFORMACION CONTENIDA EN EL EMISOR RECEPTOR FIJO AL OBJETO MOVIL. ANTENAS MULTIPLES CADA UNA DE LAS CUALES RECIBE SEÑALES SEPARADAS, PUEDEN SER MULTIPLICADAS EN EL LECTOR. EL CIRCUITO MEJORADO DE LA INVENCION PROVEE EL RAPIDO RECONOCIMIENTO DEL RECIBO DE UNA SEÑAL VALIDA DESDE UN EMISOR RECEPTOR O, AL CONTRARIO, LA AUSENCIA DE TAL SEÑAL VALIDA. EL CIRCUITO DE LA INVENCION PROVEE PRIMERO UNA DETECCION DE IMPULSO DE CORRIENTE. CADA IMPULSO DE ESTA COINCIDE EN TIEMPO CON EL BORDE ESPERADO DEL IMPULSO DE CORRIENTE PREDETERMINADO REFLEJADO TRAS EL LECTOR DESDE EL EMISOR RECEPTOR. UN CIRCUITO DE DETECCION ESTA CONECTADO PARA RECIBIR LA DETECCION DE IMPULSO DE CORRIENTE AL MISMO TIEMPO QUE LAS SEÑALES RECIBIDAS SON EVALUADAS. EL CIRCUITO DE DETECCION, DETECTA LA PRESENCIA DE BORDES DE IMPULSO QUE SON COINCIDENTES CON LOS IMPULSOS DE LA DETECCION DE SALIDA EN EL CASO DE TAL COINCIDENCIA. UN CONTADOR, CUENTA EL NUMERO DE SEÑALES DE DETECCION DE SALIDA DESDE EL CIRCUITO Y PROVEE UNA SEÑAL DE VALIDEZ QUE DEPENDE DEL NUMERO DE SEÑALES DE DETECCION DE SALIDAS RECIBIDAS POR UN NUMERO DADO DE IMPULSOS DE DETECCION. UNA EXPRESION ESCOGIDA DE LA INVENCION TAMBIEN DETECTA EL NUMERO DE IMPULSOS DE RUIDO DE FONDO CUANDO NO HAY IMPULSO DESDE LA CORRIENTE DE DETECCION DE IMPULSO. ESTAS COINCIDENCIAS INDICAN AL RECEPTOR LOS DATOS INVALIDOS, Y SON SUSTRAIDOS EN EL CONTADOR COMO SEÑAL INVALIDADA. EL APARATO DE LA INVENCION ES CAPAZ ADEMAS, DE SEPARAR RAPIDAMENTE LOS IMPULSOS DE CORRIENTE VALIDOS DE LOS INVALIDOS Y PROVEER UNA VALIDEZ O INVALIDEZ QUE PUEDE SER UTILIZADA PARA COTROLAR LA MULTIPLICACION DE UN LECTOR DESDE UNA ANTENA A OTRA.
