ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,632, issued on May 20, was assigned to Hubbell Inc. (Shelton, Conn.).

"Systems and methods for detecting and identifying arcing based on numerical analysis" was invented by William Vernon Miller III (Aldie, Va.) and Gary Michael Miller (Kearneysville, W.va.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle ...
