    Abstract: A device in a wireless power system may be operable with a removable accessory such as a case. The device may transmit or receive wireless power through the case while the electronic device is coupled to the case. The case may have a folio shape with a front cover portion that covers the display of the electronic device. The case may have an embedded ferrimagnetic core that relays magnetic flux during wireless power transfer operations. Magnetic alignment structures in the case may position the ferrimagnetic core in the case in a high magnetic flux density region between the power transmitting device and the power receiving device. The ferrimagnetic core relays the magnetic flux between a transmitting coil in the power transmitting device and a receiving coil in the power receiving device. The ferrimagnetic core may be formed in a front portion, a sidewall, or a rear wall of a case.

    Abstract: Embodiments describe a receiving element that includes a ferromagnetic structure axially symmetrical around a central axis disposed along a length of the ferromagnetic structure. The ferromagnetic structure includes a groove region defining two end regions on opposing sides of the groove region, where the groove region has a smaller length than the two end regions. The receiving element also includes an inductor coil wound about the groove region of the ferromagnetic structure and in between the two end regions. 1 of 17 Host Device 101 Communication Sensor System 108 System 110 Memory Computing User Bank 104 4-1 System 102 Interface System 106 Power Battery 112 + Transmitting Circuitry 114 I Host Inductive I Alignment ansnmitting I Interconnection I Device 124 System 105 1K Accessory Receiving Operating Device 126 Element 118 System 119 Power Battery 122 : Receiving Circuitry 120 Accessory Device 103
