According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors JIANG, Hao (Santa Clara, CA, US); LI, Shuhan (Santa Clara, CA, US), filed on June 17, 2021, was made available online on February 1, 2024. No assignee for this patent application has been made. Reporters obtained the following quote from the background information supplied by the inventors: "Hall-effect sensors are used to detect motions or positions in various applications. The hall-effect sensor picks up a magnetic field change caused by a structural deflection due to a force or torque load, and generate an electrical signal that can be mapped to the force or torque load. An existing sensor assembly uses one set of magnets and one set of hall-effect sensors on the same side of the magnets. This configuration is prevalent on position encoders. However, due to the nonlinear effect of magnetic field strength change with respect to the motion between the hall-effect sensors and the magnets in some cases, the linearity of the entire sensing signal can be impaired."
