  • Patent number: 11722007
    Abstract: A charger including a class E power driver, a frequency-shift keying (“FSK”) module, and a processor. The processor can receive data relating to the operation of the class E power driver and can control the class E power driver based on the received data relating to the operation of the class E power driver. The processor can additionally control the FSK module to modulate the natural frequency of the class E power transformer to thereby allow the simultaneous recharging of an implantable device and the transmission of data to the implantable device. The processor can additionally compensate for propagation delays by adjusting switching times.

  • Patent number: 9789325
    Abstract: Systems, methods, and devices for wireless recharging of an implanted device. In response to receiving identification information from an implanted device, a charger can set an electrical field to a first field strength and receive first field strength information from the implanted device. The charger can then set the electrical field to a second field strength and receive second field strength information from the implanted device. This information relating to the first and second field strengths can be used to determine whether to recharge the implanted device.
