Patent attributes
This application relates to a case for a portable electronic device. The case includes a magnetic boosting device, carried in a cover of the case. The magnetic boosting device includes a layer of magnetic elements including: (i) a primary magnetic element, and (ii) a secondary magnetic element. The primary magnetic element, characterized by having magnetic poles that are aligned perpendicular to the plane of the cover, provides a first magnetic field. The secondary magnetic element, characterized by having magnetic poles that are aligned parallel to the plane of the cover, provides a second magnetic field. The first magnetic field and the second magnetic field contribute to a resultant magnetic field that is asymmetrically disposed about the plane of the cover. The electronic device can include a sensor and a controller for placing the electronic device in a power saving mode when the cover is in a closed position.
