Patent number: 11968004Abstract: A wireless power system has a wireless power transmitting device and a wireless power receiving device. The devices in the wireless power system may communicate using in-band communication. The wireless power transmitting device may transmit data to the wireless power receiving device using frequency-shift keying (FSK) modulation. The wireless power receiving device may transmit data to the wireless power transmitting device using amplitude-shift keying (ASK) modulation. While transmitting data to the wireless power receiving device using FSK modulation, the wireless power transmitting device may monitor for ASK modulation from the wireless power receiving device. In response to detecting the ASK modulation from the wireless power receiving device, the wireless power transmitting device may abort the FSK data transmission and process the detected ASK modulation to receive data from the wireless power receiving device.Type: GrantFiled: June 26, 2023Date of Patent: April 23, 2024Assignee: Apple Inc.Inventors: Jeffrey D. Louis, Zaid A. AbuKhalaf

Publication number: 20240088714Abstract: A device or an accessory may include a near-field communications antenna and a soft magnetic ring concentric with the near-field communications antenna. The device or accessory may further include at least one wireless power transfer coil concentric with the near-field communications antenna, a rectifier coupled to the at least one wireless power transfer coil, and a battery configured to receive a rectified voltage from the rectifier. The soft magnetic ring may be used to shunt magnetic flux from one or more nearby magnets in external electronic devices to prevent the magnets from repelling each other. The soft magnetic ring may be attracted to a magnet in an external device to help align wireless power transfer coils in the two mated devices.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Inventor: Jeffrey D.

Patent number: 11070087Abstract: A wireless power receiving device has a receive coil that receives wireless power signals from a wireless power transmitting device and has a rectifier that produces direct-current power from the received wireless power signals. The receive coil of the wireless power receiving device is coupled to wireless transceiver circuitry. Similarly the transmit coil of the wireless power transmitting device is coupled to wireless transceiver circuitry. The wireless transceiver circuitry in the wireless power receiving device or transmitting may be configured to generate and/or modulate one or more data carrier waves using any desired modulation scheme. The one or more modulated data carrier waves are transmitted between the transmit coil and the receive coil of the corresponding wireless power transmitting and receiving devices. The one or more data carrier waves may have a frequency that is different than the power transmission frequency.Type: GrantFiled: November 19, 2018Date of Patent: July 20, 2021Assignee: Apple Inc.Inventors: Atul A.
