Abstract: Disclosed herein are automatically-configuring, universal wireless charging systems, devices, and methods for the efficient wireless transfer of power from a charging platform (310) to a battery of an electronic device (340). The charging system determines whether a proximity status indicates an electronic device is within a predefined charging distance from the charging platform. If so, the charging system automatically determines a charging power profile for a transmission coil for wirelessly charging the device, where the charging power profile is determined based on a wireless handshake protocol between the charging platform and the device to be charged. The charging system also generates a configuration message to control the transmission coil according to the charging power profile.

Abstract: Inventive aspects include systems, methods, and apparatuses for detecting placement of a wireless power receiver in a charging region of a wireless power transmitter. For example, the apparatus may include a transmit circuit comprising a transmit coil and be configured to wirelessly transmit power via a wireless filed applied to the charging region to a receive coil of the receiver. The apparatus may also include a detection circuit configured to detect a characteristic waveform resulting from the field that is applied to the charging region or changed between the transmit and receive coils, in response to the receiver being placed in the charging region.

Abstract: This disclosure provides systems, methods and apparatus including a magnetic flux device configured to transmit or receive magnetic flux. In certain configurations, the magnetic flux device can include a first coil with a first layer and second layer, a second coil with a third layer and fourth layer, and a magnetically permeable material with the first coil extending over a first edge of the magnetically permeable material and the second coil extending over a second edge of the magnetically permeable material. In certain other configurations, the magnetic flux device can include a first conductive structure including a first coil and a second coil enclosing a first area and a second area, respectively. The magnetic flux device can further include a second conductive structure with at least a first planar portion of the first conductive structure being substantially coplanar with a second planar portion of the second conductive structure.
