The U.S. Patent and Trademark Office officially published a series of 44 newly granted patents for Apple Inc. today. In this particular report we cover the iPad Smart Cover magnetic assembly and two design patents. We wrap up this week's granted patent report with our traditional listing of the remaining granted patents that were issued to Apple today.
Granted Patent: Magnetic Assembly for the iPad Smart Cover
Apple's newly granted patent covers their invention relating to various releasable attachment techniques well suited for portable electronic devices and more specifically to the iPad Smart Cover assembly.
Technically, the granted patent covers a multi-state magnetic assembly suitable for releasably attaching an accessory device to a housing of an electronic device can include a first magnet, with a surface shaped to conform with an interior surface of the housing and providing a first magnetic field and having a first polarity, a second magnet with a surface shaped to conform to an interior surface of the housing providing a second magnetic field and having a second polarity and a magnetic attractor block positioned between the first and the second magnets where the attractor block can reduce a magnetic flux density at an exterior surface of the housing.
The multi-state magnetic assembly can also include a magnetic shield made from a ferrous material having a first surface attached to the interior surface of the housing and having a second surface attached to the first and second magnets. The second surface of the magnetic shield can have a shape conforming to the surface shapes of the first and second magnets. In an inactive state, the first magnetic shield in cooperation with the magnetic attractor block can maintain a first magnetic flux density at the outer surface of the housing below a value that is capable of adversely affecting magnetically sensitive device. In an active state, a second magnetic flux density is maintained at the outer surface of the housing that exceeds a value being suitable for forming a magnetic attachment.
Apple's patent FIG. 9 is a perspective view #900 of a housing #115 including a plurality of magnetic assemblies.
Apple credits Florence OW and Jeremy Franklin as the inventors of granted patent 9,007,157 which was originally filed in August 2012and published today by the US Patent and Trademark Office.
