An apparatus suitable for use in a wellbore comprises an expandable bistable device. A perimeter sealed region can have a seal width greater than an intermediate sealed region. The polymeric encapsulation extends entirely through and fills the holes so as to integrally connect the polymeric material overlying one surface of the flange with the polymeric material overlying an opposite surface of the flange. The first fluid supply path includes first and second check valves which permit ink to flow from the ink supply tank to the inkjet printhead, but prevent fluid flow in the opposite direction. The engine control module may generate fuel injector command signals for a gaseous fuel mode based on signals received from the fuel injector control module. The present invention also provides a system for aligning a loading dock and a transport vehicle that includes a mechanism for adjusting the height of the transport vehicle or loading dock, or a plurality of engagement members that are capable of aligning the loading dock and transport vehicle.
