Method and apparatus for power transfer for a portable electronic device
First Claim
1. A power transfer system, comprising:
- a power source having a transmit coil integrated in a vehicle, the power source being driven to transmit a radio frequency (RF) power signal;
a primary repeater coil for receiving the RF power signal via magnetic coupling, the primary repeater coil being attachable to and from a garment so as to align and proximately couple with the transmit coil integrated in the vehicle;
one or more selectable secondary repeater coils for individually coupling to the primary repeater coil via a wired interconnect, the wired interconnect for routing RF power signal from the primary repeater coil to the selected secondary repeater coil, the selected secondary repeater coil being attachable to and detachable from the wired interconnect, each selected secondary repeater coil being alignable via markers on the garment, wherein different markers on the garment are associated with different sized secondary repeater coils of the one or more selectable secondary repeater coils; and
at least one portable electronic device having a receive coil, the receive coil for wirelessly receiving the RF power signal from the selected secondary repeater coil coupled to the wired interconnect.

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.

9. A method for power transfer in a portable system, comprising:
-
aligning a primary repeater coil on a garment using markers on the garment; attaching the primary repeater coil to the garment; aligning at least one secondary receiver coil on a garment using indicators on the garment, the indicators being aligned with the primary transmit coil of the garment; attaching the at least one secondary repeater coil to the garment using the indicators on the garment; receiving a radio frequency (RF) power signal at the primary repeater coil from an in-vehicle transmit coil aligned with the primary repeater coil located in the garment; transferring the RF power signal from the primary repeater coil to the at least one secondary repeater coil over a wired interconnect; and magnetically coupling the transferred RF power signal from the at least one secondary repeater coil to at least one portable electronic device having a receive coil. - View Dependent Claims (10, 11, 12)
