Abstract

EL INVENTO SE REFIERE A UN METODO Y APARATO PARA COMPROBAR LA RESPUESTA DE UN SENSOR DE ONDA DE SOBRECARGA (10) PARA CONFIRMAR QUE EL TRANSCONDUCTOR (12) Y AMPLIFICADOR (20) ESTAN FUNCIONANDO SATISFACTORIAMENTE. UN PULSADOR (24) ESTA CONECTADO AL SENSOR DE LA ONDA DE SOBRECARGA (10) EN UN PUNTO ENTRE EL TRANSCONDUCTOR (12) Y EL AMPLIFICADOR (20). EL PULSADOR (24) SUMINISTRA UN PRIMER Y SEGUNDO IMPULSO ELECTRICO EN SERIE AL SENSOR DE ONDA DE SOBRECARGA (10). EL PRIMER IMPULSO ELECTRICO TIENE UNA GRAN AMPLITUD DE MANERA QUE DA LUGAR A QUE UN TRANSCONDUCTOR OPERATIVO (12) OSCILE Y PRODUZCA UN IMPULSO ELECTRICO ADICIONAL. EL PRIMER IMPULSO ELECTRICO Y EL IMPULSO ELECTRICO ADICIONAL SE SUMINISTRAN AL AMPLIFICADOR (20). UN AMPLIFICADOR OPERATIVO AMPLIFICA EL PRIMER IMPULSO ELECTRICO Y CUALQUIER IMPULSO ADICIONAL PARA DAR UNA SEÑAL DE SALIDA, LA SEÑAL DE SALIDA INDICA SI EL TRANSCONDUCTOR O EL AMPLIFICADOR NO ESTAN FUNCIONANDO SATISFACTORIAMENTE. LA CARENCIA DE UNA SEÑAL DE SALIDA INDICA QUE EL AMPLIFICADOR ES INOPERANTE. EL SEGUNDO IMPULSO ELECTRICO TIENE UNA AMPLITUD PREDETERMINADA Y SE SUMINISTRA AL AMPLIFICADOR, Y SE AMPLIFICA MEDIANTE UN AMPLIFICADOR OPERATIVO PARA DAR UNA MEDIDA DE LA GANANCIA DEL AMPLIFICADOR.
