Abstract

UN METODO Y UN DISPOSITIVO PARA DETECTAR LOS DESECHOS/PERDIDA DE ALIMENTO PARA ANIMALES DENTRO DE UN RECEPTACULO PARA PECES (1), EN DONDE SE COLOCAN UN TRANSMISOR ACUSTICO (4) Y UN HIDROFONO (6) A MODO DE ECOBATIMETRO DIRIGIDO HACIA ARRIBA CERCA DE LA PARTE INFERIOR DEL RECEPTACULO (1). LOS ECOS SONOROS DE LOS OBJETOS SITUADOS ENCIMA DEL TRANSMISOR ACUSTICO (4) SON CAPTADOS POR EL HIDROFONO (6). UNA SEÑAL DE MEDICION (8) SEPARA LAS SEÑALES PROCEDENTES DEL HIDROFONO (6) EN VARIAS BANDAS DE FRECUENCIA CERCANAS A LA FRECUENCIA ACUSTICA TRANSMITIDA. LA DISTANCIA Y LA CANTIDAD DE LOS OBJETOS SE DETERMINAN DE FORMA PARECIDA A LA UTILIZADA EN LOS ECOBATIMETROS. LOS OBJETOS QUE SE SUMERGEN GENERARAN UNOS SONIDOS REFLEJADOS CON UNAS FRECUENCIAS LIGERAMENTE MAYORES QUE LA FRECUENCIA TRANSMITIDA, EL DENOMINADO EFECTO DOPPLER, Y LA DIFERENCIA DE FRECUENCIAS REPRESENTA UNA MEDIDA DE LA VELOCIDAD DE INMERSION DEL OBJETO. UNA UNIDAD ANALIZADORA (10) ACENTUA LAS FRECUENCIAS CORRESPONDIENTES A UNA VELOCIDADDE INMERSION CARACTERISTICA DEL TIPO DE ALIMENTO PARA ANIMALES ACTUAL (2) Y GENERA UNAS SEÑALES SOBRE EL DESECHO/PERDIDA DEL ALIMENTO PARA ANIMALES CUANDO SE DETECTA DENTRO DE UN AREA DE DISTANCIA PREDETERMINADA UNA CANTIDAD MINIMA PREDETERMINADA DE OBJETOS CON LA VELOCIDAD DE INMERSION CARACTERISTICA.
