Title: Leroy J. Willmann: Innovator in Measurement Technology
Introduction
Leroy J. Willmann is a notable inventor based in Portland, OR (US), recognized for his contributions to measurement technology. He holds 2 patents that showcase his innovative approach to solving complex problems in the field.
Latest Patents
One of his latest patents is for a "Calibration for Vector Network Analyzer." This invention presents an improved calibration method that stores sparse calibration data and interpolates system error data for each measurement. The method creates calibrated measurement data from the system error data and uncorrected measurement data at each measurement frequency. The sparse calibration data can be generated by measuring every Nth frequency step over a calibration frequency range greater than a specified measurement frequency range. Additionally, the interpolation is achieved using a curve-fit algorithm, such as a parametric polynomial curve fitting algorithm.
Another significant patent is the "Transient Distance to Fault Measurement." This method determines the distance to a fault of a transient event in a transmission system by using per frequency triggered I and Q data representing voltage and phase of a return signal in the frequency domain. The process involves filling a result set of data entries with zeros and using an initial acquisition set of per frequency I and Q data to fill a reference set. Subsequent acquisitions are compared to update the result set, which is then displayed by performing an inverse Fourier transform to provide a distance to fault display in the time domain.
