摘要： A first and second electronic device each including a connection surface and a magnetic element. The first and second devices may be in contact along the respective connection surfaces. The magnetic elements may be configured to align the first and second devices by moving either or both of the first and second devices relative to each other to achieve an aligned position. The magnetic element may also be operative to resist disconnection of first and second electronic devices when in the aligned position.

摘要： 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.

摘要： 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.

摘要： A wireless charger for an electronic device. The charger includes a base having a base opening and an interior cavity defined by an upper shell, a lower shell 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 that is 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 has a charging surface and a power transmitting unit disposed adjacent to the charging surface where the power transmitting unit is configured to wirelessly transmit power across the charging surface to a power receiving unit of a portable electronic device.
