Abstract

DETECTOR DE GRADIENTE DE PRESION ACUSTICA APTO PARA DETECTAR UNA SEÑAL SONORA, CARACTERIZADO PORQUE LLEVA: UN MEDIO MECANOACUSTICO CONSTITUIDO POR UNA ESFERA (1) SENSIBLE DE MANERA OMNIDIRECCIONAL AL GRADIENTE DE PRESION, UN MEDIO ELECTROMECANICO (3,4) QUE RECIBE EL MEDIO MECANOACUSTICO DESTINADO A TRANSFORMAR LOS ESFUERZOS EN IMPULSOS ELECTRICOS, Y MEDIOS ELECTRONICOS DE TRATAMIENTO DE ESTOS IMPULSOS. EL MEDIO ELECTROMECANICO ESTA CONSTITUIDO POR DOS CIRCUITOS IMPRESOS (3,4) QUE LLEVAN AMPLIFICADORES DE BAJO RUIDO SEPARADOS POR VIGAS (5) QUE DELIMITAN UNA ESTRUCTURA TRIANGULADA, QUE LLEVA UN CALIBRE (6) DE MEDICION DE LAS TENSIONES. APLICACION EN LA LOCALIZACION Y EL SEGUIMIENTO DE VEHICULOS.
