Latest Patents

Ulsund's latest patents focus on the analysis of noise in repetitive waveforms. One of his systems is designed for precisely measuring time intervals, which can either characterize or diminish noise components in repetitive waveforms. The interval timer generates a whole number count of cycles, combined with beginning and ending ramps that can resolve fractions of a cycle to accurately register the time interval. Selection logic can be implemented to time either single periods or spans of multiple consecutive periods of the waveforms. Multiple time measurements are arranged in sets, each corresponding to a different span of “N” consecutive periods over a range of values for N. A variance of each set is generated, and an array of variance vs N provides a function with properties of an auto-correlation function. Instrument jitter can be reduced based on measurements of period spans rather than individual periods, and this reduction is proportional to the increasing size of the measured span. These techniques are further enhanced by random statistical samples obtained through dithering of the measurement rate, which also diminishes the impact of aliasing products.
