  • Self-balancing frequency determining bridge
    Patent number: 8330447
    Abstract: A self-balancing Wheatstone bridge that provides frequency and power information. The frequency information obtained can be applied to correct the power measurement to provide excellent match, excellent frequency insensitivity, good dynamic range, good frequency range, and adequate frequency accuracy. The system is highly responsive, simple, and cost effective.

  • Method for eliminating the need to zero and calibrate a power meter before use
    Patent number: 7911199
    Abstract: An improved power sensor having an input connector connected to an input port having a center pin and a ground side; an amplifier; first and second detectors; and a thermal stabilization system, including a thermal mass disposed between the ground side of the input connection and the detectors, a ground plane for holding the temperature of thermally sensitive components constant to within 2 degrees C., and a thermal impedance disposed between the center pin of the input port, preferably including a splitter and at least one DC capacitor, and a temperature sensor disposed on the ground plane.
