Abstract
EN UN DISPOSITIVO PARA REGULAR EL UNCIONAMIENTO DE UN ASPIRADOR Y PARA SEÑALIZAR EL GRADO DE LLENADO DE LA BOLSA DEL ASPIRADOR, UNA OBSTRUCCION DEL TUBO, O FALSAS ABERTURAS DE AIRE, ETC. SE PROPONE COLOCAR UNA TURBINA DE AIRE (19) EN LA CORRIENTE DE AIRE GENERADA POR EL TORBELLINO DEL ASPIRADOR TRAS ESTE TORBELLINO Y DETRAS DE LA BOLSA DE POLVO ASPIRADO (13), CUYO NUMERO DE REVOLUCIONES SE TRANSFORMA EN UNA SEÑAL ELECTRICA DE AVISO. TAMBIEN POSEE UN INTERRUPTOR CONMUTADOR PARA EL GOBIERNO DEL MOTOR DEL VENTILADOR (15). SEGUN LA MASA DE AIRE ABSORBIDA SE PUEDE DETECTAR LA CAPACIDAD DE SERVICIO DEL ASPIRADOR O DEL GRADO EN QUE ESTA LLENA LA BOLSA, HECHOS QUE REPRESENTAN SEÑALES INDICADORAS DE CAMBIO Y DATOS PORCENTUALES GRADUADOS CON FINURA ASI COMO COMUNICACIONES OPTICAS ESCRITAS PARA EL USUARIO. UNA COMBINACION CON VALORES DE PRESION REGISTRADOS CON CONECTORES DE MEMBRANA POSIBILITA FACILMENTE UN DISCERNIMIENTO SEGURO DEL ESTADO DE FUNCIONAMIENTO QUE HAY QUE SEÑALAR.
