Abstract
The disclosed technology relates to wireless communication and wireless power transmission. In some implementations, the disclosed technology is directed to an integrated circuit having a transmitter that transmits radio frequency (RF) based wireless power and receives signals for detecting the location of a client device. The disclosed technology is also directed to an integrated circuit for a client device that receives power from the transmitter and transmits beacon signals, which the transmitter can use to locate the client device.
Claims20
A system for transmitting wireless power, the system comprising:
- a processor;
- a memory coupled to the processor and storing instructions for transmitting wireless power and receiving beacon signals from a client device according to a power delivery schedule and beacon schedule, respectively;
- a clock source configured to synchronize transmission of wireless power;
- at least four antenna management units (AMUs) configured to transmit radio frequency (RF) wireless power and receive beacon signals from the client device,
- wherein each of the AMUs includes:
- a transceiver configured to switch between receiving the beacon signals from the client device and transmitting an RF power waveform to the client device;
- a phase shifter configured to adjust a phase of the RF power waveform based on the received beacon signals;
- and
- a phase detector configured to detect a phase of the received beacon signals,
- wherein each transceiver is configured to concurrently transmit the RF power waveform to the client device;
- and
- at least one an antenna coupled to each of the AMUs.
An integrated circuit comprising:
- at least four antenna management units (AMUs) configured to transmit radio frequency (RF) wireless power and receive beacon signals from a client device,
- wherein each of the antenna modules includes:
- a transceiver configured to
- receive the beacon signals from the client device via an antenna port and,
- transmit an RF power waveform to the client device via the antenna port;
- a phase shifter configured to adjust a phase of the RF power waveform based on the received beacon signals;
- and
- a phase detector configured to detect a phase of the received beacon signals,
- wherein each transceiver is configured to concurrently transmit the RF power waveform to the client device.
A tangible computer-readable storage medium containing machine-implementable instructions which, when executed by a system having at least four antenna management units (AMUs), cause the system to:
- transmit a beacon signaling schedule to a client device;
- send a control signal to a transceiver directing the transceiver to switch an antenna from transmitting wireless power to receiving beacon signals;
- process a beacon signal of the beacon signals received from the client device, wherein the beacon signal is received in accordance with the beacon signaling schedule;
- amplify the received beacon signal;
- detect a phase of the amplified beacon signal;
- determine an adjusted phase for transmitting wireless power to the client device at least partially based on the detected phase of the amplified beacon signal;
- send control instructions to a phase shifter for transmitting the adjusted phase wireless power;
- amplify the adjusted phase wireless power for the client device;
- and
- transmit the adjusted phase wireless power to the client device.
