Abstract: Electric fields that can cause corrosion of contacts can be compensated for by embodiments of the present invention. For example, voltage waveforms at the contacts can be made to have a zero volt average, and therefore have a zero net electric field. Galvanic voltages generated by dissimilar metals used by a contact and a housing can generate an electric field, and currents motivated by the galvanic electric field can be blocked by capacitively coupling the contacts to their corresponding circuits.

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.

Abstract: A wireless charging mat and method of operating the same. The wireless charging mat includes a detection system configured to determine a location and an orientation of an electronic device on the wireless charging mat. The location and orientation are determined based on detected locations of one or more structural features of the electronic device. The wireless charging mat is operated according to the detected location and orientation.

Abstract: A cable can include a cable core surrounded by an outer sleeve having a uniform thickness and further having a first longitudinal section having a first stiffness (e.g., corresponding to a flexible cable), a second longitudinal section having a second stiffness (e.g., corresponding to a rigid cable), and a third longitudinal section between the first and second longitudinal sections, where the second stiffness is greater than the first stiffness and where a stiffness of the third longitudinal section varies between the first stiffness and the second stiffness. The second longitudinal section can provide strain relief for the cable.

Abstract: An electronic device and methods for inductively charging an electronic device using another external electronic device. The electronic device may include an enclosure, a battery positioned within the enclosure, and an inductive coil coupled to the battery. The inductive coil may have two or more operational modes, including a power receiving operational mode for wirelessly receiving power and a power transmitting operational mode for wirelessly transmitting power. The electronic device may also have a controller coupled to the inductive coil for selecting one of the operational modes.
