Patent abstract
An apparatus comprises a base, a top member, and a bladder. The top member defines a proximal end and a distal end. The proximal end of the top member is pivotally coupled to the base. The bladder, in turn, is disposed between the base and the top member. Arranged in this manner, the apparatus is operative to raise the distal end of the top member away from the base as the bladder is inflated.
