Title: Innovations of Thomas Penney, III
Introduction
Thomas Penney, III is an accomplished inventor based in South Salem, NY (US). He has made significant contributions to the field of magnetoresistive sensors, holding a total of 3 patents. His work has been instrumental in advancing technology in this area.
Latest Patents
One of his latest patents is for a magnetoresistive sensor with magnetic flux paths surrounding non-magnetic regions of a ferromagnetic material layer. This innovative sensor includes a substrate and a layer of ferromagnetic material formed over it. A plurality of nonmagnetic regions is created within the layer, allowing magnetic flux paths to form around each nonmagnetic region when the ferromagnetic material is not in a magnetic field. The sensor is designed to detect changes in resistance through the ferromagnetic layer as a function of an applied magnetic field.
Another notable patent involves a magnetoresistive sensor with magnetostatic coupling of magnetic regions. This invention incorporates multiple magnetic stripes spaced apart on a substrate's surface. The stray magnetic fields at the ends of these stripes are magnetostatically coupled, and the stripes are magnetized in alternating directions. Nonmagnetic conductive material is positioned between the stripes, with electrodes passing current crosswise to detect changes in resistance through the giant magnetoresistive effect (MGR). This invention addresses the challenge of detecting low magnetic fields by controlling the magnetostatic coupling through the geometry and position of the magnetic stripes.
