Abstract

UN CIRCUITO DE PRUEBA PARA UN SISTEMA DE CONFINAMIENTO POR BOLSA DE AIRE SE REVELA Y PROVEE UNA MUY VERAZ DETERMINACION DE LA OPERATIVIDAD DE UN ALMACENADOR Y CALCULA LA RESISTENCIA DE LOS INTERRUPTORES-RESISTORES DE INERCIA. EL ALMACENADOR SE PRUEBA CARGANDOLO Y DESCARGANDOLO. LOS VALORES DE LOS INTERRUPTORES-RESISTORES DE INERCIA SE DETERMINAN CAMBIANDO VALORES DE RESISTIVIDAD CONOCIDOS EN PARALELO CON LOS INTERRUPTORES-RESISTORES DE INERCIA. BASANDONOS EN LOS VALORES DE TENSION MOSTRADOS DURANTE EL CAMBIO, SE CALCULAN LOS VALORES DE LAS RESISTENCIAS.
