  • Patent number: 11958413
    Abstract: A foreign object detecting system and a method are provided. A control circuit controls a light transmitter and a light receiver. The light transmitter is disposed adjacent to a detected object and emits a light signal toward the detected object. The light receiver is disposed adjacent to the detected object in a path along which the light signal reflected by the detected object travels. The light receiver receives the light signal reflected to the light receiver. In a pre-operation, the control circuit defines the light signal received by the light receiver when the foreign object is not on the detected object as a first reflected light signal. In a detection operation, the control circuit determines that a difference exists between the light signal currently received by the light receiver and the first reflected light signal, the control circuit determines that the foreign object is on the detected object.
