ALEXANDRIA, Va., May 26 -- United States Patent no. 12,638,478, issued on May 26, was assigned to Schneider Electric USA Inc. (Boston).
"Compact current sensing for protection and wiring devices" was invented by Andi Jakupi (Marion, Iowa) and Juan Ignacio Melecio Ramirez (North Liberty, Iowa).
According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for sensing current utilize a coil-less sensor based circuit to detect current. The current sensing circuit includes a first conductive line segment that carries mains AC current, and a second conductive line segment conductively coupled in electrical parallel to the first line segment. The coil-less sensor is mounted between the two conductive line segme...
