ALEXANDRIA, Va., Jan. 13 -- United States Patent no. 12,523,690, issued on Jan. 13, was assigned to Advanced Energy Industries Inc. (Denver).

"Capacitance sensing systems and methods" was invented by Donald Enzinna (Lockport, N.Y.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems, methods, and apparatuses for measuring capacitance of a load. An apparatus includes a ground connector, an output connector configured to couple to the load, and a time-varying signal source configured to inject a time-varying voltage signal onto a conduction path between the ground connector and the output connector. A DC power source or amplifier is configured to apply a DC offset to the time-varying voltage signal, and a cu...
