Abstract
A wireless power system may include a power transmitting device for transmitting wireless power to a power receiving device that receives the wireless power. The power transmitting device can include data communications facilities for sending and receiving data packets. The power transmitting device can selectively turn off its data communications facilities. The power receiving device can include data communications facilities for sending and receiving data packets. The power receiving device can selectively turn off its data communications facilities.
Claims20
A method of operating an electronic device, comprising:
- with a wireless power transfer coil, transmitting wireless power to a power receiving device;
- with a data receiver coupled to the wireless power transfer coil, obtaining a packet transmitted from the power receiving device;
- determining whether the packet has an associated silent period;
- and
- in response to determining that the packet has an associated silent period, deactivating one or more communications components of the electronic device during at least a portion the silent period.
A power transmitting device comprising:
- a wireless power transfer coil;
- an inverter configured to supply alternating-current signals to the wireless power transfer coil for transmitting wireless power to a power receiving device;
- a data receiver coupled to the wireless power transfer coil and configured to obtain a packet, transmitted from the power receiving device, having an associated communications silence period;
- and
- control circuitry configured to deactivate the data receiver during at least a portion of the communications silence period.
A non-transitory computer-readable storage medium storing one or more programs configured to be executed by one or more processors of a power transmitting device configured to transmit wireless power to a power receiving device, the power transmitting device comprising a wireless power transfer coil and a data receiver coupled to the wireless power transfer coil, and the one or more programs comprising instructions for:
- processing a packet at the data receiver;
- determining whether the packet has an associated silent period;
- and
- in response to determining that the packet has an associated silent period, deactivating the data receiver during at least a portion of the silent period.
Control circuitry coupled to a wireless power transfer coil of a power transmitting device, the control circuitry being configured to:
- initiate communications with a power receiving device during which the wireless power transfer coil transmits wireless power to a power receiving device;
- process a packet received from the power receiving device during the communications;
- determine whether the packet has an associated silent period;
- and
- deactivate one or more communications component of the power transmitting device during at least a portion of the silent period in response to determining that the packet has an associated silent period.
