General Electric Assigned Patent for High Temperature Electronics for Passive Eddy Current Sensors

General Electric has been assigned a patent (7,948,229) developed by John Weickert for "high temperature electronics for passive eddy current sensors." The patent is designed to sense the periodic proximity of one or more objects, such as the rotating blades of a gas turbine, and eliminate electromagnetic interference noise. The system uses a passive eddy current sensing unit with first and second magnets and coil-wound cores to generate and detect magnetic fields. The patent was filed on August 29, 2008, and the full-text is available at the U.S. Patent and Trademark Office website.
