Abstract: A power transfer interface (120) is formed of a primary repeater coil (104) and one or more secondary repeater coils (106) coupled via a wired interconnect (110), and integrated within a garment (114). The repeater coils operate as part of a wireless charging or powering system in which a transmit coil (102), located in a vehicle or a radio, is driven to magnetically couple a wireless radio frequency (RF) power signal to the primary repeater coil (104) which in turn transfers the RF power signal to the secondary repeater coil (106) via the wired interconnect (110). The system further comprises a portable electronic device (220) having a receive coil (108). The receive coil (108) wirelessly receives the RF power signal from the secondary repeater coil (106), which can in turn be used to power the portable device or charge a battery of the portable device.

Abstract translation: 电力传输接口（120）由初级中继器线圈（104）和经由有线互连（110）耦合并且集成在服装（114）内的一个或多个次级中继线圈（106）形成。 中继器线圈作为无线充电或供电系统的一部分操作，其中位于车辆或无线电中的发射线圈（102）被驱动以将无线射频（RF）功率信号磁耦合到主中继线圈（ 104），其又通过有线互连（110）将RF功率信号传送到次级中继器线圈（106）。 该系统还包括具有接收线圈（108）的便携式电子设备（220）。 接收线圈（108）无线地接收来自次级中继器线圈（106）的RF功率信号，其可以用于为便携式设备供电或为便携式设备的电池充电。
