A wireless charging system for a planar wireless accessory includes a receiving coil positioned within the planar wireless accessory and a transmitting coil positioned within a planar electronic device. The transmitting coil generates a magnetic flux that is received by the receiving coil to charge a battery of the planar wireless accessory when the planar wireless accessory is positioned relative to the planar electronic device according to a select charging configuration of multiple user-selectable charging configurations. The transmitting coil and the receiving coil are shaped and positioned to charge the battery at a substantially uniform rate at each different one of the multiple user-selectable charging configurations.

Wireless charging at substantially uniform charge rate for different physical charge configurations

A device for inductively charging an electronic accessory includes a first portion, a second portion, and a spacer. The first portion includes a first transmission coil in a first plane where the first transmission coil is configured to generate a first magnetic field, and the second portion includes a first transmission coil in a second plane where the second transmission coil is configured to generate a second magnetic field. The spacer is positioned between the first transmission coil and the second transmission coil and between the first plane and the second plane. The spacer material magnetically insulates the second transmission coil from the first magnetic field.

Two-sided inductive charging coil

The description relates to devices and/or device accessories. One example can include a Hall effect sensor configured to sense magnetic fields along a sensing axis and a pair of elongate magnets having co-axial and opposite magnetic axes that are perpendicular to the sensing axis.

Device orientation sensor

A locking apparatus is described. The locking apparatus includes a first sliding member that includes a first locking arm that extends from the first sliding member, a first tab that extends from the first locking arm, and a first locking aperture assembly. The locking apparatus includes a second sliding member that includes a second locking arm that extends from the second sliding member and a second locking aperture assembly configured to cooperate with the first locking aperture assembly to form an aperture configured to prevent relative motion between the first sliding member and the second sliding member when a locking protrusion is inserted therethrough. A locking system and a kit for securing a computing device are described. Methods of use are also provided.
