Assignee: SONY GROUP CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A detecting apparatus comprising:
a plurality of magnetic coupling elements including at least one power transfer coil and detection coils, the detection coils being configured to distribute magnetic flux in opposing orientations;
a positioning unit disposed near a respective coil from among the power transfer coil or the detection cons; and
a detector that measures an electrical parameter related to the plurality of magnetic coupling elements or to a circuit that includes the plurality of magnetic coupling elements, and determines from a change in the electrical parameter whether a foreign matter that generates heat due to magnetic flux is present, wherein
the electrical parameter is a 0 factor of the plurality of magnetic coupling elements or of the circuit that includes the plurality of magnetic coupling elements,
a number of the detection cons is twice a number of the power transfer coils and
wherein the positioning unit includes two raised sections at opposing ends of and defining an opening, and portions of at least two of the detection cons are disposed in the opening.
