Abstract: A first electronic device connects with an second electronic device. The first electronic device may include a first connection surface and an inductive power transfer receiving coil and a first magnetic element positioned adjacent to the first connection surface. The second electronic device may similarly include a second connection surface and an inductive power transfer transmitting coil and second magnetic element positioned adjacent to the second connection surface. In the aligned position, alignment between the electronic devices may be maintained by magnetic elements and the inductive power coils may be configured to exchange power. The magnetic elements and/or the inductive power coils may include a shield that is configured to minimize or reduce eddy currents caused in the magnetic elements by the inductive power coils.

Abstract: An inductor coil includes a wire which is wound in alternating layers such that the surface area of the wire in each winding viewed from above or below the coil is substantially equal in each half of the coil defined by a line bisecting the center point in each layer. The layers are also wound in a serpentine fashion to balance the capacitance between layers. The substantially equal surface area of wire in each half of a coil layer and in adjacent coil layers results in a balanced capacitance of the coil which, in turn, results in reduced common mode noise.

Abstract: A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more conductive traces in the transmitter device based on the position of the receiver device on the charging surface. The size and shape of each section of the charging surface that is used to transfer energy to a receiver device can change dynamically based on each receiver device. Additionally, the process of transferring energy to each receiver device may be adjusted during energy transfer based on conditions specific to each receiver device.

Abstract: A charging assembly for wireless power transfer. In embodiments, the charging assembly comprises a housing, a cap structure, a ferrimagnetic sleeve, an inductive coil, a magnet, a printed circuit board assembly (PCBA), and a four-pin connector extending from a bottom surface of the PCBA. A ridge of the cap structure can be coupled to a lip of the housing. The housing can include a bottom housing surface having an aperture, and a sidewall extending between the bottom housing surface and the lip that extends outward from the sidewall along a perimeter of the housing parallel to the bottom housing surface. The four-pin connector can extend through the aperture of the housing. Some embodiments are directed to a charging device that incorporates the charging assembly.

Abstract: The present disclosure includes systems and methods for magnetically orienting ferrites in an inductive power transfer system. In one example embodiment, a method for forming a ferrite element having oriented magnetic dipoles includes heating a ferrite element to a first temperature, the ferrite element comprising a non-magnetic matrix having magnetic particulates suspended therein, and, while heating, applying an external magnetic field to the ferrite element to align magnetic dipoles of the particulates with the direction of the magnetic field.

Abstract: Methods of and systems for directing flux from a transmit coil to a receive coil within an inductive power transfer system are disclosed. For example, a transmit coil can be shielded with a contoured shield made from a ferromagnetic material. The contoured shield can contour to several surfaces of the transmit coil so as to define a single plane through which flux is directed to the receive coil.
