Patent ID: 7844305

Claim:
An apparatus for creating power for a mobile communication device, comprising: a roller integrated into the mobile communication device, the roller configured to rotate in a counterclockwise direction about a roller axis of rotation when the roller contacts a surface and is moved in a first direction, and the roller configured to rotate in a clockwise direction when the roller contacts a surface and is moved in a second direction; gearing connected to the roller, wherein the gearing rotates when the roller is moved, the gearing including: at least one main gear coupled to the roller, the at least one main gear configured to rotate about a main gear axis of rotation co-linear with the roller axis of rotation; a first pinion gear coupled to the at least one main gear, the first pinion configured to rotate about a first pinion gear axis of rotation parallel with the roller axis of rotation; and a second pinion gear coupled to the at least one main gear, the second pinion gear configured to rotate about a second pinion gear axis of rotation parallel with the roller axis of rotation; and one or more generators, the one or more generators including: a first generator coupled to the first pinion gear, the first generator configured to generate power in the mobile communication device upon rotation of the roller and the gearing; and a second generator coupled to the second pinion gear, the second generator configured to generate power in the mobile communication device upon rotation of the roller and the gearing.
