Apple was won a patent on the magnet technology in the Smart Cover for the iPad, and a so-far unused "peek mode" concept, says AppleInsider. The patent describes a magnetic assembly designed to ensure that the accessory can be easily aligned and attached to a tablet that has its own built-in magnets. More critical to the patent are tablet sensors used to detect the presence of a magnetic field, which in the case of the iPad shut the device on and off when the Smart Cover is lifted or closed.
