Latest Patents

One of his latest patents is titled "Anomaly detection in energy systems." This invention provides a method and system for detecting anomalies in energy systems using non-contact sensing based on electric and magnetic fields. The system employs non-contact electric- and magnetic-field sensors to generate signals, which are then filtered to eliminate noise. Features are extracted and normalized from these signals to characterize their parameters. The invention utilizes density-based spatial clustering to identify anomalies from data points that do not conform to normal operational clusters. The clustering process may involve the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm, and Fourier analysis is used for feature extraction.

Another significant patent is the "Apparatus and method for DC-component-based fault classification of three-phase distribution power cables with magnetic sensing." This invention employs an array of magnetic sensors arranged around the surface of a three-phase power distribution cable to measure the magnetic field. The system includes a magnetic shield to block background magnetic fields and a data acquisition system that captures analog signals from the sensors. The processing system extracts DC components from these signals during transient periods following a fault, utilizing mathematical morphology to identify potential DC components that arise during faults.
