Latest Patents

One of his latest patents is the "Permanent Magnet Array Iron Filter." This invention features a generally circular collar made of high magnetic permeability material, with multiple magnetic assemblies arranged longitudinally around its interior circumference. Each assembly consists of two magnets with opposite poles facing the center, creating a strong magnetic field that penetrates deeply within the filter. Rare earth permanent magnets are utilized to maximize the magnetic field, and the collar is designed with a plastic coating for protection and flexibility during use.

Another notable patent is the "Magneto-Optic Remote Sensor for Angular Rotation, Linear Displacements, and Evaluation of Surface Deformations." This system detects angular rotation, linear displacement, and surface deformations by utilizing the interaction of linearly polarized light with magnetic materials. The method leverages the Faraday effect, with a basic structure consisting of a magneto-optic film and a gradient magnetic field produced by opposite polarity permanent magnets. The oscillation of the magnetic domain wall in the film leads to a detectable output signal, providing valuable information on various movements and deformations.
