    Abstract: A wireless communication device includes a wireless charging circuit configurable to receive a wireless power signal from a power transmitting unit and to charge the wireless communication device under control of a processing device and in conjunction with a charging session with the power transmitting unit. A wireless interface device operates under control of the processing device to establish a wireless connection with the power transmitting unit via a connection establishment procedure, wherein the wireless connection is separate from the wireless power signal. Control data is exchanged with the power transmitting unit via the wireless connection, wherein the control data is used by the processing device to implement the charging session with the wireless charging circuit. A response is generated to a disruption event of the wireless communication device that includes implementing a restoration procedure for restoring the wireless connection, without implementing the connection establishment procedure.

    Abstract: A monitoring device may monitor its proximity to a monitored station. The monitored station may transmit a proximity indicator to the monitoring device. For example, the proximity indicator may include the received signal strength of a signal sent by the monitored station. Wireless interface control circuitry at the monitoring device may monitor the status of the proximity indicator for changes. If one or more criteria set by an application processor are met by a detected change, the wireless interface control circuitry may send a status update to the application processor. In the criteria are not met, generation of the status update may be forgone. The application processor need not monitor the proximity indicator status and may remain in a reduced power consumption mode for longer periods.

    Abstract translation: 监控设备可以监视其与受监视站的距离。 受监控站可以向监控设备发送接近指示符。 例如，接近指示符可以包括受监视站发送的信号的接收信号强度。 监控设备上的无线接口控制电路可以监视接近指示器的状态以进行更改。 如果通过检测到的改变满足应用处理器设置的一个或多个标准，则无线接口控制电路可以向应用处理器发送状态更新。 在不符合条件的情况下，状态更新的生成可能会被放弃。 应用处理器不需要监视接近指示器状态，并且可以在较长时间内保持在降低的功耗模式。

    Abstract: A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets.
