Latest Patents

One of his notable inventions is the "Adaptive Sinusoidal Interference Filter." This invention relates to an adaptive filtering system designed to cancel one or more sinusoidal interference signals contained within a desired signal in an incoming signal. The system utilizes a phase-locked loop to track the sinusoidal interference frequency and synthesize various synchronous in-phase/in-quadrature square wave signals. These signals are weighted according to variations in the amplitude and phase of the interference signal, allowing for the delivery of a desired signal that is substantially free from interference. In cases involving multiple correlated signals, this filtering system demonstrates steady-state performance that is significantly better than the well-known Widrow-Hoff adaptive notch filter.

Another significant patent is the "Apparatus and Method for Measuring the Roughness of Lumber." This invention provides a method and apparatus for automatically measuring the thickness and roughness of elongated articles, such as wooden boards. The device features a housing with an opening to receive a portion of the board to be measured. It includes at least one contact probe that senses irregularities in the flatness of the surface along a measured length. A measuring circuit connected to the probe provides a measurement signal representative of the sensed irregularities and variations in thickness. Additionally, a distance measuring device measures the displacement of the board past the contact probe, while an output display indicates selected measurements. A computing means accumulates measured values, including minimum and maximum thickness, for a group of boards, allowing for the extraction of statistical information.
