Abstract
Wireless power transfer systems, disclosed, include a wireless power transmission system and a wireless power receiver system. The wireless power transmission system includes a transmitter antenna configured to couple with a receiver antenna to transmit alternating current (AC) wireless signals to the receiver antenna. Antenna coupling may be inductive and may operate in conformance to a wireless power and data transfer protocol. A transmission controller drives the transmitter antenna at an operating frequency, and either the wireless power transmission system or the wireless power receiver system may damp the wireless power transmission to create a data signal containing a serial asynchronous data signal.

A wireless power transfer system comprising:
- a wireless power transmission system comprising:
- a transmitter antenna configured to couple with at least one receiver antenna and transmit wireless alternating current (AC) signals to the at least one receiver antenna;
- a transmission controller integrated circuit including a first memory, the first memory storing instructions for:
- providing a driving signal for driving the transmitter antenna based on an operating frequency for the wireless power transfer system, wherein the transmitter antenna is configured to emit a transmission in accordance with the driving signal, and wherein the driving signal is configured to generate a power signal and a first asynchronous serial data signal in accordance with a wireless power and data transfer protocol,
- decoding the power signal to extract a second data signal that is compliant with the wireless power and data transfer protocol, and
- decoding the second data signal to extract a second asynchronous serial data signal;
- and
- a wireless power receiver system comprising:
- the at least one receiver antenna configured for inductive coupling with the transmitter antenna and receiving the transmission from the transmitter antenna, the at least one receiver antenna operating based on the operating frequency for the wireless power transfer system;
- a power conditioning system configured to receive the transmission from the at least one receiver antenna, convert the received transmission to a direct current (DC) power signal, and provide the DC power signal at least to a load associated with the wireless power receiver system;
- and
- a receiver controller integrated circuit including a second memory, the second memory storing instructions for:
- decoding the transmission to extract a first data signal compliant with the wireless power and data transfer protocol and decode the first data signal compliant with the wireless power and data transfer protocol to extract the first asynchronous serial data signal,
- encoding the second asynchronous serial data signal as the second data signal compliant with the wireless power and data transfer protocol,
- selectively altering the power signal to encode the second data signal compliant with the wireless power and data transfer protocol into the power signal.
