ALEXANDRIA, Va., March 19 -- United States Patent no. 12,253,576, issued on March 18, was assigned to Allegro MicroSystems LLC (Manchester, N.H.).
"Self-calibrating magnetoresistance-based magnetic field sensors" was invented by Hernan D. Romero (Buenos Aires, Argentina).
According to the abstract* released by the U.S. Patent & Trademark Office: "Systems, circuits, and methods provide self-calibration for magnetoresistance-based magnetic field sensors. Examples can include use of a closed loop acting as a feedback or calibration loop that is configured to process a reference signal applied to one or more magnetoresistance elements in a MR-based magnetic field sensor that also detects one or more external magnetic fields. The closed loop c...
