Latest Patents

One of Woodard's latest patents focuses on the adaptive removal of resonance-induced noise. This innovation allows for the removal of noise from the digitized output of a sensor that is subject to undesired resonance. Notably, this process can occur even when the resonant frequency is unknown or drifts. The technology employs a very narrow notch filter that is recursive (IIR), ensuring a low phase delay suitable for closed-loop control applications. The apparatus determining the center frequency of the notch filter is non-recursive, providing stability. It includes a tunable FIR filter that tracks the same resonance the IIR filter aims to eliminate. By tuning the FIR filter to minimize its output, the notch frequency aligns with the resonant frequency. The tuning parameter, which adaptively produces this result, is suitably scaled and biased, and is applied to the IIR filter.
