Abstract: A compliant mount for use in a connector or connection adapter is disclosed. The compliant mount may be used in a connection between a portable electronic device and another electronic device, such as a docking station. A compliant mount connector adapter may include a first end connector engageable with a portable device and a second end connector engageable with another device, the first and second end connectors coupled with a compliant mount allowing movement of the first end connector engaged with the portable device relative to the second end connector when engaged within the other electronic device. The compliant mount may include any or all of: elastomers, springs, torsion bars, elastomers, rigid members or housing, ball and socket joints, resilient bendable members, and dongles to allow for controlled resistance to bending or torsional forces applied to the portable device when connected to the other electronic device with the connector adapter.

Abstract: A magnetic alignment system can include a primary annular magnetic alignment component and a secondary annular magnetic alignment component. The primary alignment component can include an inner annular region having a first magnetic orientation, an outer annular region having a second magnetic orientation opposite to the first magnetic orientation, and a non-magnetized central annular region disposed between the primary inner annular region and the primary outer annular region. The secondary alignment component can have a magnetic orientation with a radial component. Additional features, such as a rotational magnetic alignment component and/or an NFC coil and circuitry can be included.

Abstract: Charging devices that can securely hold an electronic device in a useful position, fold into a compact shape, and provide power to the electronic device. One example can provide a wireless charger that can include a wireless charging assembly, a base, and a hinge connecting the wireless charging assembly to the base. When opened, the wireless charging assembly can be positioned upright relative to the base such that an electronic device being charged by the wireless charging assembly can be maintained in an upright position for easy viewing. The wireless charging assembly can be rotated, folded, or otherwise closed into a cavity or passage in the base, which can provide for easy transport. The hinge can be configured to readily open for use, while providing increased friction to resist closing. This increased friction can help the charger to securely hold the electronic device in place while charging.

Abstract: An inductive charging dock is disclosed that includes a charging dock housing defining an interior volume. The inductive charging dock housing is configured to support a portable electronic device during a wireless charging operation and includes a radio frequency (RF) transparent window. An induction coil is disposed within the interior volume and configured to generate a magnetic flux that exits the charging dock housing through the RF transparent window. A cooling fan is disposed within the interior volume and is configured to establish a flow of cooling air along a path that extends through an air gap between the induction coil and the RF transparent window

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: 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: A wireless charger includes a base having a base opening and an interior cavity defined by upper and lower shells and an inner sidewall extending between the upper and lower shells to define the base opening. An aperture is formed through the inner sidewall between the interior cavity and the base opening and a hinge is connected to the base within the interior cavity and extends through the aperture. The charger further includes a wireless charging assembly pivotably attached to the base by the hinge and moveable between a down position in which the wireless charging assembly is disposed within the base opening and an up position in which the wireless charging assembly extends outside the base. The charging assembly is configured to wirelessly transmit power across the charging surface to a power receiving unit of a portable electronic device.

Abstract: In some embodiments, an electronic device includes an electronic component that is at least partially encapsulated by an adhesive doped with soft magnetic material that functions as an EMI shield for the electronic component. In various embodiments, an electronic device includes a first magnetic component separated from a second magnetic component by a gap within which is positioned an adhesive doped with soft magnetic material. The doped adhesive is positioned in a magnetic path between the first and second magnetic components and aids in magnetically coupling the first and second magnetic components and/or guides magnetic flux between the first and second magnetic components.
