Patent ID: 8769772

Claim:
A mobile electronic device comprising: a first member having a first surface and a second surface opposite to the first surface; a second member; and at least one linkage mechanism coupling the first member and the second member such that the device may be moved between a first position and a second position, the at least one linkage mechanism comprising: a linkage intermediate the first member and the second member; and a motion constraint mechanism that constrains movement of the first member with respect to the second member between the first and second positions to a pre-defined rotational and translational path, the rotational and translational path being defined by rotation of the first member with respect to the second member and counter-rotation of the linkage with respect to the second member, wherein when the device is in the first position, the first member overlies the second member, the first surface is accessible and faces away from the second member, and the second surface faces toward the second member, and when the device is in the second position, the first member overlies the second member, the second surface is accessible and faces away from the second member, and the first surface faces toward the second member.
