Latest Patents

One of his latest patents is a "Method of foreign object detection and foreign object detection device." This invention includes a processor, a detecting circuit assembly connected to the processor, a coil connected to the detecting circuit assembly, a signal generator connected to both the processor and the detecting circuit assembly, and a coil configuring circuit connected to the processor and the coil. The processor outputs a control signal to the coil configuring circuit to generate a switch signal, enabling the coil to switch between a closed mode and an open mode. When in the open mode, the processor controls the signal generator to transmit a test signal to the coil via the detecting circuit assembly.

Another significant patent is for a "Wireless power transmission device and foreign object detection coil thereof for detecting metallic foreign objects." This device radiates electromagnetic waves through a transmission antenna and generates multiple sensed signals using several foreign object detection (FOD) coils. Each FOD coil consists of three coil units connected in series and spaced apart. The radiation pattern of the transmission antenna overlaps the sensing range of the FOD coils. A controller determines if any metallic foreign object enters the radiation range and stops the generation of electromagnetic waves to prevent heating of the metallic object.
