Title: Innovations by Stephen J Hanson
Introduction
Stephen J Hanson is an accomplished inventor based in Princeton, NJ (US). He has made significant contributions to the field of electric motor monitoring and anomaly detection. With a total of 3 patents, his work focuses on enhancing the reliability and efficiency of electric motors.
Latest Patents
One of his latest patents is titled "Method and system for ascertaining anomalies in electric motors." This invention involves a computer-based system that processes Fast Fourier Transforms (FFT's) of supply current waveforms to identify anomalies in electric motors. The method utilizes Ward's clustering technique to derive input vector assignments and computes the Approximate Weight of Evidence (AWE) for each cluster grouping. A warning signal is generated if the input sample deviates from the defined clusters.
Another notable patent is the "Neural network auto-associator and method for induction motor monitoring." This method detects deviations from normal operation by training a neural network auto-associator with a set of normal current measurements. It compares current measurements during operation with the normal set and indicates abnormal operation when deviations exceed a predetermined threshold. The model effectively predicts potential failures in electric motors.
