Latest Patents

Gravel's notable patent is titled "Apparatus and methods for the shunt calibration of semiconductor strain." This invention discloses a technique for shunt calibration of a Wheatstone bridge array that operates independently of temperature. The structure includes a side completion half bridge array, which features two temperature-sensitive resistors as semiconductor strain gauges forming one arm of the bridge, while two temperature-insensitive resistors form the other arm. An input voltage is applied to two opposite terminals of the bridge through equal span resistors, and an output is taken between the common terminals of each bridge arm. A calibration resistor is strategically positioned to shunt a span resistor and a temperature-insensitive resistor, providing a calibrated output voltage that remains independent of temperature.
