Wireless power transfer with in-band virtualized wired communications

A receiver-side host device comprising:

• a receiver-side antenna;
• a load;
• and
• a receiver-side control system that is configured to perform a set of functions comprising:
• receiving an alternating current (AC) signal induced at the receiver-side antenna by an alternating electromagnetic field that is being emitted by a transmitter-side host device to deliver wireless power to the receiver-side host device;
• based on the received AC signal, generating a direct current (DC) signal for charging the load of the receiver-side host device;
• and
• introducing a change in the alternating electromagnetic field being emitted by the transmitter-side host device that is representative of an in-band data signal from the receiver-side host device, wherein the in-band data signal (i) is formatted in accordance with a wireless power and data transfer protocol and (ii) carries, as payload, embedded data originating from the receiver-side host device that is formatted in accordance with a data communication protocol different from the wireless power and data transfer protocol.

A wireless transfer system comprising:

• a transmitter-side host device;
• and
• a receiver-side host device that includes a load,
• wherein the transmitter-side host device is configured to:
• emit an unmodulated alternating electromagnetic field that delivers wireless power to the receiver-side host device;
• and
• thereafter emit a modulated alternating electromagnetic field that delivers both wireless power and wireless data to the receiver-side host device, wherein the wireless data comprises an in-band data signal that (i) is formatted in accordance with a wireless power and data transfer protocol and (ii) carries, as payload, embedded data originating from the transmitter-side host device that is formatted in accordance with a data communication protocol different from the wireless power and data transfer protocol;
• and
• wherein the receiver-side host device is configured to:
• detect the unmodulated alternating electromagnetic field that delivers wireless power to the receiver-side host device, wherein the unmodulated alternating electromagnetic field induces an unmodulated alternating current (AC) signal at the receiver-side host device;
• based on the unmodulated AC signal, generate a direct current (DC) signal for charging the load of the receiver-side host device;
• thereafter detect the modulated alternating electromagnetic field that delivers both wireless power and wireless data to the receiver-side host device, wherein the modulated alternating electromagnetic field induces a modulated AC signal at the receiver-side host device;
• based on the modulated AC signal, decode the in-band data signal from the transmitter-side host device;
• and
• after decoding the in-band data signal, decode the embedded data originating from the transmitter-side host device.
