  • Systems and methods providing output sample frequency determinism by calculating a delay with a wall clock and using a timer to compensate for the delay
    Patent number: 8726063
    Abstract: A computer-implemented method for performing processing including setting a timer associated with a first processing event, scheduling an expected time for the processing event using wall clock time, at the timer, using the expected time to calculate a delay associated with the timer, performing the first processing event in response to the timer, and setting a subsequent timer to compensate for the delay.

  • Method and apparatus for configurable sample rate conversion in teleoperated devices
    Patent number: 8606838
    Abstract: Disclosed is an efficient and configurable apparatus and method for sample rate conversion using interpolation. The apparatus and method employ a configuration file to change the conversion coefficients, sampling rate, and interpolation algorithm without having to recompile control software and/or reprogram the controlled device. In some embodiments, the interpolation employs polynomial interpolation, which may include Lagrange interpolation. In some embodiments, the interpolation method is selected to minimize the loop delay in teleoperation applications.
