Abstract

A device for applying a force to a planar surface includes a tub, a cavity, a membrane, and an opening. The tub includes a bottom wall, at least one sidewall, and a cavity defined between the bottom and sidewalls. The membrane is disposed within the cavity and a perimeter edge of the membrane is fixed to the tub. The opening is formed in the tub and adapted to receive a pressurized fluid to fill a portion of the cavity below the membrane to displace at least a portion of the membrane away from the bottom wall to apply a force to the planar surface.
