ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,165, issued on May 20, was assigned to Hamilton Sundstrand Corp. (Charlotte, N.C.).
"Solenoid position estimation systems" was invented by Gordon Elliott Winer (Prescott, Ariz.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A system can include an inductance module configured to operatively connect to a solenoid. The inductance module can be configured to input an AC excitation signal to the solenoid, determine and/or compare a current-voltage (CV) phase shift between a solenoid current and solenoid voltage, and output an output signal indicative of solenoid inductance based on the CV phase shift."
