  • Dynamic filter tuning for pulse-echo ranging systems
    Patent number: 7139220
    Abstract: Dynamic tuning of a tunable filter within the receiver of a pulse-echo ranging system. A filter tuning module compares a transmit signal and a filtered signal to obtain a phase difference indicative of any mis-match between the resonant frequency of the tunable filter and the transmit frequency. The filter tuning module outputs a phase correction signal corresponding to the phase difference and a controller uses the phase correction signal to determine any adjustments necessary to minimize the phase difference. Adjustments to the tunable filter may be made with each ‘shot’ or transmission.
    Type: Grant

  • Method and apparatus for improving accuracy in ultrasonic echo ranging systems
    Patent number: 7010973
    Abstract: A method and apparatus for calibrating and/or improving the accuracy of time of flight ranging or level measurement systems. A correction factor is determined and applied to the calculated receive times for echo pulses in response to a change in the amplitude of the echo pulses or in response to a change in the noise floor.
