Latest Patents

Imazawa's latest patents focus on the development of foreign object detectors. One of his inventions includes a foreign object detector that features multiple detection coils positioned between a transmitter coil in a transmitter device and a receiver coil in a receiver device. This design allows for electromagnetic coupling between the coils. The system incorporates multiple capacitors that form resonant circuits with the detection coils. A power supply circuit provides alternating current power at a predetermined frequency to each detection coil through a feeder coil, which is also electromagnetically coupled to the detection coils. The detection circuit detects voltage outputs from each detection coil, enabling the identification of foreign objects between the transmitter and receiver coils based on the detected voltage.

Another patent by Imazawa describes a similar foreign object detector that includes detection coils situated between a transmitter coil and a receiver coil. This invention also features a power supply circuit that supplies AC power at a predetermined frequency to each detection coil through a feeder coil. The detection circuit monitors the criteria voltage from each detection coil at the start of power supply and outputs a signal to halt power supply to the transmitter coil if any detection coil's criteria voltage deviates from a predetermined range.
