In general, a device to be charged and a charging device may interact using two separate wireless signals. A first wireless signal (e.g., a radio frequency (RF) signal) may be employed to charge the device. A second wireless signal of a different type (e.g., an infrared (IR) signal) may be employed for inter-device communication. An example device may comprise a power module to receive a first wireless signal, a transmitter to transmit a second wireless signal, and a charging control module. The first wireless signal may be for conveying power from a charging device to the device, the second wireless signal may be for transmitting information from the device to the charging device, and the charging control module may be to cause the transmitter to transmit the second wireless signal based on an indication received from the power module. ## Claims ### Claim 1 A device, comprising: a power module to receive a first wireless signal for conveying power from a charging device to the device; a transmitter to transmit a second wireless signal for conveying information from the device to the charging device; and a charging control module to cause the transmitter to transmit the second wireless signal based on an indication received from the power module. ### Claim 2 (depends on 1) The device of claim 1, wherein the power module comprises wireless charging circuitry to receive the first wireless signal, the first wireless signal being a radio frequency (RF) signal. ### Claim 3 (depends on 2) The device of claim 2, wherein the wireless charging circuitry comprises at least a coil to generate a charging current based on the RF signal. ### Claim 4 (depends on 1) The device of claim 1, wherein the second wireless signal is an infrared (IR) signal. ### Claim 5 (depends on 1) The device of claim 1, wherein the transmitter is part of the power module. ### Claim 6 (depends on 5) The device of claim 5, wherein the charging control module is part of the power module. ### Claim 7 (depends on 1) The device of claim 1, wherein the indication relates to at least one of the first wireless signal or device power condition. ### Claim 8 (depends on 1) The device of claim 1, wherein the information transmitted in the second wireless signal comprises at least one of status or instructions related to the indication. ### Claim 9 (depends on 1) The device of claim 1, further comprising a receiver to receive a third wireless signal for conveying information from the charging device to the device. ### Claim 10 A method, comprising: receiving a notification from a power module in a device that a first wireless signal has been received; and causing a second wireless signal to be transmitted by a transmitter in the device, the second wireless signal initializing power transfer to the device via the first wireless signal. ### Claim 11 (depends on 10) The method of claim 10, wherein the first wireless signal is a radio frequency (RF) signal. ### Claim 12 (depends on 10) The method of claim 10, wherein the second wireless signal is an infrared (IR) signal. ### Claim 13 (depends on 10) The method of claim 10, further comprising receiving an indication from the power module, the indication relating to at least one of the first wireless signal or device power condition. ### Claim 14 (depends on 13) The method of claim 13, further comprising causing information to be transmitted via the second wireless signal, the information including at least one of status or instructions related to the indication. ### Claim 15 At least one machine-readable storage medium having stored thereon, individually or in combination, instructions that when executed by one or more processors result in the following operations comprising: receiving a notification from a power module in a device that a first wireless signal has been received; and causing a second wireless signal to be transmitted by a transmitter in the device, the second wireless signal initializing power transfer to the device via the first wireless signal. ### Claim 16 (depends on 15) The medium of claim 15, wherein the first wireless signal is a radio frequency (RF) signal. ### Claim 17 (depends on 15) The medium of claim 15, wherein the second wireless signal is an infrared (IR) signal. ### Claim 18 (depends on 15) The medium of claim 15, further comprising instructions that when executed by one or more processors result in the following operations comprising: receiving an indication from the power module, the indication relating to at least one of the first wireless signal or device power condition. ### Claim 19 (depends on 18) The medium of claim 18, further comprising instructions that when executed by one or more processors result in the following operations comprising: causing information to be transmitted via the second wireless signal, the information including at least one of status or instructions related to the indication.
