Magnetic systems for electronic devices and accessories

摘要

A cover is described that is magnetically attached to a tablet device. The cover includes at least as flap. In the described embodiment, the flap includes a plurality of segments where the first segment includes a first plurality of edge attach magnets arrayed along a first edge of the flap and where a second segment includes a second plurality of edge attach magnets arrayed along a second edge of the flap opposite the first edge.

主权项

1. A cover configured for releasably attaching to a tablet device having a display and associated top protective layer, a plurality of sensors, and a processor coupled to the display and the plurality of sensors, comprising:
a flap having a size and shape in accordance with the top protective layer, the flap comprising: a first sensor magnet having a first size located at a first position in the flap and detectable through the top protective layer by a first sensor when the flap is in a closed configuration; and a second sensor magnet having a second size located at a second position in the flap, the second position different than the first position, the second sensor magnet being detectable through the top protective layer by a second sensor different from the first sensor in the closed configuration, wherein the first size and the second size are such that the first and second magnets remain detectable by the first and second sensors, respectively, regardless an amount of racking that the flap undergoes in the closed configuration.
