  • Patent number: 9698730
    Abstract: The exemplary embodiments include methods, computer readable media, and devices for calibrating a non-linear power detector of a radio frequency device based upon measurements of the non-linear power detector output and the associated power amplifier output level, and a set of data points that characterize a nominal non-linear power detector. The set of data points that characterize the nominal non-linear power detector is stored in a calibration system memory as nominal power detector output data. The measured non-linear power detector outputs, power amplifier output levels, and the nominal power detector output data is used to determine a power detector error function that characterizes the difference between the response of the non-linear power detector and the nominal non-linear power detector. The power detector error function and the nominal power detector output data are used to develop a calibrated power detector output data set that is stored in the non-linear power detector.

  • Patent number: 9689726
    Abstract: A flow meter ultrasonically measures fluid velocity in a pipe. Ultrasonic signals received by ultrasonic transducers are digitized. The difference between two ultrasonic propagation times is determined by computing a discrete cross-correlation of the digitized received signals. Computation time is reduced by computing only a few cross-correlation values near a peak cross-correlation value.
