Wireless power and data transfer for electronic devices

A method for wireless charging, the method comprising:

• detecting, at a wireless charging device, a request for wireless charging via a wireless power transfer field, the request received from a chargeable device;
• receiving, via a field disturbance of the wireless power transfer field, an indication signal that the chargeable device is ready to transmit or receive information;
• establishing a wireless data link with the chargeable device in response to the received indication signal, the wireless data link being over a wireless medium different than the wireless power transfer field;
• and
• wirelessly transmitting power at a level sufficient to charge or power the chargeable device via the wireless power transfer field.

A wireless charging device, comprising:

• means for wirelessly transmitting power at a level sufficient to power or charge a chargeable device via a wireless power transfer field:,
• means for detecting a request for wireless charging via the wireless power transfer field, the request received from the chargeable device;
• means for receiving, via a field disturbance of the wireless power transfer field, an indication signal that the chargeable device is ready to transmit or receive information;
• and
• means for establishing a wireless data link with the chargeable device in response to the received indication signal, the wireless data link being over a wireless medium different than the wireless power transfer field.

A chargeable device configured to wirelessly receive power, the chargeable device comprising:

• means for wirelessly receiving power from a wireless charging device via a wireless power transfer field at a level sufficient to charge or power the chargeable device;
• means for providing a request for wireless charging to the wireless charging device via the wireless power transfer field;
• means for transmitting, via a field disturbance of the wireless power transfer field, an indication signal that the chargeable device is ready to transmit or receive information;
• means for establishing a wireless data link with the wireless charging device in response to transmitting an indication signal, the wireless data link being over a wireless medium different than the wireless power transfer field.

A chargeable device configured to wirelessly receive power, the chargeable device comprising:

• a receiver configured to wirelessly receive power from a wireless charging device via a wireless power transfer field at a level sufficient to charge or power the chargeable device;
• and
• a processor configured to:
• provide a request to the wireless charging device for wireless charging, the request provided via the wireless power transfer field;
• transmit an indication signal of readiness to transmit or receive information, the indication signal provided via a field disturbance of the wireless power transfer field;
• and
• establish a wireless data link with the wireless charging device in response to transmitting the indication signal, the wireless data link being over a wireless medium different than the wireless power transfer field.

A method for wirelessly receiving power, the method comprising:

• providing a request from a chargeable device to a wireless charging device, the request provided via a wireless power transfer field;
• transmitting an indication signal that the chargeable device is ready to transmit or receive information, the indication signal provided via a field disturbance of the wireless power transfer field;
• establishing a wireless data link with the wireless charging device in response to transmitting the indication signal, the wireless data link being over a wireless medium different than the wireless power transfer field;
• and
• wirelessly receiving power from the wireless charging device via the wireless power transfer field at a level sufficient to charge or power the chargeable device.

A chargeable device configured to wirelessly receive power, the chargeable device comprising:

• a receiver configured to wirelessly receive power from a wireless charging device via a wireless power transfer field at a level sufficient to charge or power the chargeable device;
• and
• a processor configured to:
• send a first request to the wireless charging device for wireless charging, the first request provided via the wireless power transfer field;
• send a second request to establish a wireless data link, the second request provided via the wireless power transfer field;
• and
• transfer data to the wireless charging device via the wireless data link in response to providing the second request.

A wireless charging device, comprising:

• a transmitter configured to wirelessly transmit power at a level sufficient to charge or power a chargeable device via a wireless power transfer field;
• and
• a controller configured to:
• detect a first request for wireless charging via the wireless power transfer field, the request received from the chargeable device;
• receive a second request to establish a wireless data link with the chargeable device, the second request received via the wireless power transfer field from the chargeable device;
• and
• send initiation data to the chargeable device via the wireless power transfer field in response to the second request to establish the wireless data link.
