摘要： Embodiments describe electromagnetic shielding for wireless charging systems. A wireless charging system includes a transmitter coil configured to generate a magnetic flux, a receiver coil positioned coaxial with the transmitter coil to receive the generated magnetic flux, where electrical interaction between the transmitter coil and the receiver coil generates electric fields, a transmitter shield positioned between the transmitter coil and the receiver coil to intercept some of the electric fields directed away from the transmitter coil and allow the magnetic flux to pass through the transmitter shield, and a receiver shield positioned between the transmitter shield and the receiver coil to intercept some of the electric fields directed away from the receiver coil and allow the magnetic flux to pass through the receiver shield.

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 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.

摘要： A charging assembly (100) for wireless power transfer. In embodiments, the charging assembly comprises a housing (140), a cap structure (110), a ferrimagnetic sleeve (325), an inductive coil (315), a magnet (350), a printed circuit board assembly (PCBA) (360), and a four-pin connector (210) extending from a bottom surface of the PCBA. A ridge of the cap structure can be coupled to a lip (220) of the housing. The housing can include a bottom housing surface having an aperture (215), 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.
