Patent 7960979 was granted and assigned to Honda on June, 2011 by the United States Patent and Trademark Office.
A universal resistance testing device is provided and includes a bridge circuit, a metering circuit, a comparator circuit, and an output circuit. The universal resistance testing device is incorporated into a control circuit and is used to verify a resistive value of a variable resistance device. The universal resistance testing device includes multiple replaceable resistors to thereby allow the universal resistance testing device to be used in the same control circuit to test different variable resistance devices having a different resistive value.
