Latest Patents

One of Howard R Branch's latest patents is titled "Ridge circuit compensation for environmental effects." This invention describes a method and apparatus for using a computer to compensate for zero point and span errors, as well as other non-linearities in the operation of strain gauge transducers. The apparatus includes a semiconductor strain gauge transducer with a quasi-stable voltage supply, two strain gauges, and two precision resistors forming a voltage divider network. A scanner is employed to scan the strain gauges and precision resistors, while an analog-to-digital converter digitizes the output of the scanner. A microprocessor calculates a corrected output representing the monitored phenomenon. The microcomputer contains a memory storing bridge completion constants, correction constants, and temperature compensation algorithms.

Another notable patent is the "Temperature compensated bridge circuit." This invention measures the voltage drops across a series-connected pair of strain gauges and arbitrary resistance at zero and maximum stresses at three temperatures. The appropriate resistance for span compensation is calculated from these values, and the process involves adjusting resistors to achieve optimal temperature compensation. This innovative approach ensures accurate measurements across varying temperatures, enhancing the performance of strain gauge transducers.
