The transmitting coil receives and wirelessly radiates power from a power supply to a receiver of a vehicle. In response to the radiated power from the transmitting coil, the first detection coil generates a first voltage, and the second detection coil generates a second voltage. A comparison system is electrically coupled to the transmitter. The comparison system declares presence of a foreign object in proximity to the transmitter in response to a difference between the first voltage and a first reference voltage exceeding a threshold value. The comparison system declares the presence of the foreign object in response to a difference between the second voltage and a second reference voltage exceeding the threshold value. The transmitter is selectively disabled in response to presence of the foreign object being declared."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Foreign object detection in a wireless power transfer system","description":"A wireless power transfer system includes a transmitter with a transmitting coil, a first detection coil, and a second detection coil.
