Abstract

LA CONFIGURACION DEL CIRCUITO DE ACUERDO CON LA INVENCION, CONTROLA UNA LINEA DE TRANSMISION (UL) EN CUANTO A LA TRANSMISION DE SEÑALES DE ACTIVACION E INCLUSO ESTA EN CONDICIONES DE PROPORCIONAR SEÑALES DE ACTIVACION A LA LINEA DE TRANSMISION (UL). DESPUES DE LA DETECCION DE UNA SEÑAL DE ACTIVACION, ORIGINA LA CONFIGURACION DEL CIRCUITO LA ACTIVACION DE UN APARATO (EG) UNIDO CON LA LINEA DE TRANSMISION (UL), EL CUAL POR ELLO CAMBIA DESDE EL ESTADO DE REPOSO AL ESTADO DE SERVICIO NORMAL. POR TANTO, EL APARATO (EG) SE ENCUENTRA CADA VEZ SOLO EN ESTADO DE SERVICIO NORMAL, CUANDO SE UTILIZA DE MODO EFECTIVO POR EL USUARIO. POR ESE MOTIVO RESULTA EN CONJUNTO UNA CARGA DE LAS UNIDADES DE ABASTECIMIENTO DE CORRIENTE NOTABLEMENTE MENOR. ADEMAS, LA CONFIGURACION DEL CIRCUITO DE ACUERDO CON LA INVENCION, PERMITE LA DETECCION SEGURA DE SEÑALES DE ACTIVACION, TAMBIEN AUNQUE EN LA LINEA DE TRANSMISION (UL) TODAVIA EXISTAN SEÑALES DE PERTURBACION O UTILES.
