Patent ID: 8470432

Claim:
A hard cover comprising: a composite material layer having a shape, a first surface, a second surface, a perimeter, and a foot region having a thickness from 1/16 of an inch to 1.0 inch, the first surface and the second surface spaced apart approximately equal distant from each other with the first surface and the second surface conforming to the shape of the composite material layer, the composite material layer including a first material layer having a first thickness, a second material layer having a second thickness, a first transition region and a second transition region having a first variable thickness and second variable thickness, respectively, the first material layer extends from the foot region through the first transition region with the first variable thickness diminishing through the first transition region, the second material layer disposed on at least a portion of the first transition region of the first material layer and extending through the center region with the second variable thickness increasing through the second transition region, and the foot region including a substantially flat portion capable of resting on a substrate, wherein the substantially flat portion of the foot region supports the hard cover.
