Latest Patents

Ning Liu holds a patent for a method titled "Foreign object detection using combined inductive and thermal sensing." This invention focuses on detecting foreign metal objects near inductive wireless power transfer systems. The method utilizes a sensing system that combines inductive and thermal effects to identify the presence of an object. The system includes a sense element with an electrical characteristic that changes in the presence of the object based on the inductive effect. Additionally, a mediating heat-sensitive material varies its properties with temperature, affecting the electrical characteristic of the sense element. This material is heated by the foreign object when exposed to a magnetic field generated by the wireless power transfer system. A controller measures the electrical characteristic and determines the presence of the object based on the changes observed.
