摘要： An induction charging device for an electrically operated motor vehicle may include at least one charging assembly. The at least one charging assembly may include a charging coil, a ferrite assembly, a metal shielding plate, and a temperature-control assembly through which a fluid is flowable. The charging coil may be inductively couplable to a primary coil such that a motor vehicle battery is inductively chargeable. The ferrite assembly may include a plurality of rotatable ferrite plates arranged next to one another. When in a closed position, a respective ferrite plate may be arranged parallel to the charging coil and may shield the metal shielding plate from the charging coil. When in an open position, the respective ferrite plate may be arranged at an angle relative to the charging coil and may partially shield the metal shielding plate from the charging coil.

摘要： A mobile device mounting system includes a device case and a mount. The device case includes: an insert including a rectangular bore and defining a set of undercut sections about the rectangular bore; and a first set of magnetic elements arranged in a first pattern about the rectangular bore. The mount includes: a body; a polygonal boss extending from the body and configured to insert into the rectangular bore; a set of locking jaws arranged on the polygonal boss configured to transiently mate with the set of undercut sections to constrain the polygonal boss within the rectangular bore; and a second set of magnetic elements arranged in a second pattern about the polygonal boss and configured to transiently couple to the first set of magnetic elements to transiently retain the mount against the device case and to drive the set of locking jaws toward the set of undercut sections.

摘要： A power transmitter for wireless power transfer includes a control and communications unit, an inverter circuit, a coil, and a shielding. The control and communications unit is configured to provide power control signals to control a power level of a power signal configured for transmission to a power receiver, provide a power request to an external power supply, determine if a power signal at the coil is compliant with the power request, and, if the power signal at the coil is compliant with the power request, continue to operate for wireless power transmission. The coil is configured to transmit the power signal to a power receiver. The shielding comprises a ferrite core.

摘要： In a wireless charging system, a transmitter coil of a wireless charger device and a receiver coil of a portable electronic device can operate at either of two different operating frequencies. The low frequency can be in a range from about 300 kHz to about 400 kHz, and the high frequency can be in a range from about 1 MHz to about 2 MHz. To provide efficient charging at both frequencies, the transmitter and receiver coils can be formed from a compound, or multi-stranded, wire.
