Latest Patents

Yu P Ma's latest patents demonstrate sophisticated techniques for identifying flaws in electrically conductive materials and ensuring food product safety. One patent details a method and apparatus for detecting flaws below the surface of a material by utilizing a sheet inducer that carries a uniformly distributed AC current. This process induces a sheet eddy current parallel to smooth surfaces of electrically conductive objects. A superconducting quantum interference device (SQUID) magnetometer then detects variations in the magnetic field caused by disturbances from flaws, allowing for enhanced detection capabilities. His innovation allows the detection of flaws of different sizes, shapes, and depths by inducing currents in multiple directions and at various frequencies.

The second patent focuses on an apparatus and method for the on-line inspection of electrically conductive food products. By immersing items such as fish fillets in a saline solution that matches the electrical conductivity of unspoiled products, Ma and his team are able to detect inclusions and spoilage. This system utilizes magnetic field perturbations caused by discontinuities in conductivity, effectively alerting operators to potential contamination. Notably, his method achieves impressive production line inspection rates, making it suitable for high-demand environments.
