  • Patent number: 10637301
    Abstract: Multiple wireless power receiving devices operating in accordance with potentially different wireless charging protocols may be placed on a wireless power transmitting device. The wireless power transmitting device sends a frequency-shift-keying packet. If a wireless power receiving device is compliant with a first wireless charging protocol, the device responds to the frequency-shift-keying packet with an amplitude-shift-keying response packet. If the wireless power receiving device is compliant with a second wireless charging protocol, the wireless power receiving device will fail to respond to the frequency-shift-keying packet and the wireless power transmitting device responds by stopping and starting wireless power transmission and awaiting an amplitude-shift-keying packet from the wireless power receiving device in accordance with the second wireless charging protocol.

  • Patent number: 10581282
    Abstract: Foreign object detection (FOD) is provided for wireless energy transfer systems. A transmitter receives an input voltage, converts it to an output current, supplies the output current to a transmit coil, and samples a first set of analog signals to generate a first set of digital values. A receiver converts a current induced in a receive coil by energy transferred from the transmit coil into an output voltage, samples a second set of analog signals to generate a second set of digital values, and communicates the second set of digital values to the transmitter. The transmitter generates a FOD signal based upon the first and second sets of digital values that indicates detection or non-detection of a foreign object within the energy transfer. In further embodiments, a comparison of the detected power loss or efficiency to expected power loss or efficiency is used to generate the FOD signal.
