    Abstract: An apparatus for wirelessly transmitting charging power is provided. The apparatus comprises a transmit coil configured to generate a wireless charging field for wirelessly transmitting charging power when driven by a current. The apparatus comprises a control circuit configured to cause the transmit coil to transmit a packet via the wireless charging field, wherein the packet comprises information indicative of the presence of the wireless charging field to cause a chargeable device to electrically disconnect a communication circuit from a receive coil within the chargeable device. The control circuit is further configured to cause the transmit coil to transmit the packet periodically based on a predetermined interval. The predetermined interval has a shorter duration than a duration of a communication interval of the communication circuit. The control circuit is further configured to reduce a magnitude of a strength of the wireless charging field during packet transmission.

    Abstract: In one aspect, an apparatus for wirelessly coupling with other devices is provided. The apparatus includes a metallic cover having a removed portion. The apparatus comprises a first coil substantially wound around the removed portion of the metallic cover and configured to communicate with at least one other device via a communications protocol. The metallic cover comprises a second coil substantially wound around the removed portion of the metallic cover and configured to wirelessly and inductively receive charging power sufficient to charge or power the apparatus from at least one wireless charging power transmitter.

    Abstract translation: 在一个方面，提供了一种用于与其他设备无线耦合的设备。 该装置包括具有去除部分的金属盖。 该装置包括基本上缠绕在金属盖的去除部分上的第一线圈，并被配置为经由通信协议与至少一个其它设备通信。 金属盖包括基本上缠绕在金属盖的去除部分上的第二线圈，并且被配置为无线和感应地接收足以从至少一个无线充电功率发射器对设备充电或供电的充电功率。
