ALEXANDRIA, Va., March 12 -- United States Patent no. 12,247,855, issued on March 11, was assigned to SEMICONDUCTOR COMPONENTS INDUSTRIES LLC (Scottsdale, Ariz.).
"Inductive angular position sensor" was invented by Jacques Jean Bertin (Pocatello, Idaho).
According to the abstract* released by the U.S. Patent & Trademark Office: "An inductive sensor may track an angle of a movable element. In some cases, it is desirable to operate the inductive sensor using battery power so that turns are tracked properly even when power is lost. The disclosed inductive sensor includes circuitry to conserve power, such as a non-resonant driver that allows for fast measurements without wasting energy and a difference encoder that can estimate the angle with...
