Latest Patents

One of Soderstrand's latest patents is titled "Adaptive Removal of Resonance-Induced Noise." This invention addresses the issue of noise in the digitized output of sensors that are subject to undesired resonance. The technology is designed to operate effectively even when the resonant frequency is unknown or fluctuates. The solution employs a very narrow notch filter that is recursive (IIR), allowing for low phase delay, which is crucial for closed-loop control applications. The apparatus determining the center frequency of the notch filter is non-recursive, ensuring stability. It features a tunable FIR filter that tracks the resonance intended for removal by the IIR filter. By tuning the FIR filter to minimize its output, the notch frequency aligns with the resonant frequency, resulting in effective noise reduction.
