摘要： Systems, devices, methods and computer readable media for wireless power transfer with improved device identification and signaling security are provided. A Power Receiving Unit (PRU) (102) may include a receive resonator module (104) to receive power from a Power Transmitting Unit (PTU) (112) over an inductive resonant coupling link (108). The power may be modulated to provide signaling between the PRU (102) and the PTU (112) over the resonant coupling link (108). The PRU (102) may also include a signaling link communication module to provide a second type of signaling between the PRU (102) and the PTU (112) over a wireless communication link (110). The PRU (102) may further include a controller module to receive a random number, generated by the PTU (112), over the resonant coupling link (108); calculate an encoded response based on the random number and on an identifier of the PRU (102); and transmit the encoded response to the PTU (112) over the wireless communication link (110), for verification by the PTU (112).

摘要： Wireless link management techniques for wireless charging systems are described. According to some such techniques, a power receiving unit (PRU) may be configured to observe a rectifier voltage while operating in a charge complete connected (CCC) mode according to which it possesses a wireless connection with a power transmitting unit (PTU) operating in a power save state. In various embodiments, the PRU may be configured to observe the rectifier voltage in an attempt to detect power beacons generated by the PTU. In some embodiments, the PRU may be configured to maintain the wireless connection if it detects power beacons, and to terminate the wireless connection if it does not detect any beacons. Other embodiments are described and claimed.
