Abstract
A resistive strain gauge bridge circuit, including a pulse code modulation counter operative under an algorithm designed for calibration with a voltage signal for effectively canceling out voltage and voltage fluctuation influences to maintain centering of the operating point of the strain gauges without the excessive costs attributable to devices such as electronic potentiometers which notably have been utilized to generally achieve satisfactory performance of strain gauges included in mobile personal computer systems.
