ALEXANDRIA, Va., Dec. 2 -- United States Patent no. RE50,684, issued on Dec. 2, was assigned to Everspin Technologies Inc. (Chandler, Ariz.).
"Three axis magnetic field sensor" was invented by Phillip Mather (Phoenix), Jon Slaughter (Slingerlands, N.Y.) and Nicholas Rizzo (Gilbert, Ariz.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Three bridge circuits (101, 111, 121), each include magnetoresistive sensors coupled as a Wheatstone bridge (100) to sense a magnetic field (160) in three orthogonal directions (110, 120, 130) that are set with a single pinning material deposition and bulk wafer setting procedure. One of the three bridge circuits (121) includes a first magnetoresistive sensor (141) comprising a ...
