Latest Patents

One of his latest patents is a position sensing mechanism. This invention comprises an encoding element as a sensing signal source, a reading element for sensing signals of the signal source, and a processing unit for receiving and analyzing sensing signals output by the reading element. The main technical feature of this position sensing mechanism lies in a magneto-resistive unit in the reading element, which utilizes a tunneling magneto-resistor (TMR). The design includes two layers of magnetic moments in a reference layer and a free layer that are perpendicular to each other, with one layer's magnetic moment parallel to the film surface and the other perpendicular to it.

Another notable patent is a linear position detecting device applied to a linear motion system for motion measurement. This device includes a coding element and a detecting element that corresponds to the coding element for retrieving the signal to provide position information. The coding element consists of a base with an axial direction parallel to its length and a radial direction perpendicular to it. The first coding unit is configured on the base with multiple first tracks extended along the axial direction and alternately arranged along the radial direction. The second coding unit, adjacent to the first, comprises several second tracks extended along the radial direction and alternately arranged along the axial direction.
