Abstract

EN UN DISPOSITIVO PARA MANDO DE UN LIMPIAPARABRISAS MEDIANTE UN SENSOR DE LLUVIA FORMADO COMO EMISOR PIEZOELECTRICO SE LLEGA A ELIMINAR LAS INFLUENCIAS NOCIVAS EN EL EMISOR, POR EJEMPLO, POR SACUDIDAS MECANICAS. PARA CONSEGUIR UN MANDO LO MAS EXACTO POSIBLE DERIVADO DE LA INTENSIDAD DE LLUVIA, SE PROPONE CONSTRUIR EL SENSOR DE LLUVIA DE AL MENOS DOS PEZOELEMENTOS SEPARADOS ELECTRICAMENTE UNO DE OTRO, CUYAS SEÑALES DE MEDICION SE VALORAN EN DOS RECORRIDOS PARALELOS Y SE COMPARAN SEGUIDAMENTE UNA CON OTRA. CORRESPONDIENTEMENTE AL RESULTADO DE LA COMPARACION SE ACCIONA SEGUIDAMENTE EL IMPULSO DEL LIPIAPARABRISAS. EL INVENTO RECONOCE QUE LA INGLUENCIA NOCIVA SE PRODUCE REGULARMENTE DE FORMA SIMILAR EN AMBOS ELEMENTOS. POR LO TANTO SE RECONOCE Y NO SE TOMA EN CONSIDERACION EN LA VALORACION.
