Abstract: A system for transporting inventory includes an inventory holder and a mobile drive unit. The inventory holder includes a frame capable of storing inventory items and a docking plate capable of receiving a docking head from underneath. The mobile drive unit, includes a docking head capable of coupling to the docking plate and a drive module capable of propelling the mobile drive unit. The mobile drive unit is further capable to move the inventory holder when the docking head is coupled to the inventory holder.

Abstract: A laminated fuel cell plate has a sheet metal layer compression molded between two layers of expanded graphite. The sheet metal layer provides resilient support for making thinner plates. The sheet metal layer also functions as a permeability barrier, which allows the conductivity of the expanded graphite layers to be enhanced. Features are molded into the graphite layers for such purposes as alignment, sealing, and flow control.

Abstract: A modular sliding window assembly for in a motor vehicle body is provided with a sliding pane subassembly which has a snap-fit with a frame subassembly. The frame subassembly preferably comprises a pair of fixed panes, an upper and lower applique, and an injection molded cover member integrating the fixed panes and the appliques. The sliding pane subassembly preferably comprises a generally horizontal run channel member and at least one glazing pane optionally having a run channel guide affixed to a peripheral edge of the pane. The pane is slidably received in a run channel formed by the run channel member. The horizontal run channel member has a snap-fit attachment preferably to one of the appliques. The appliques can have a flexible flange or the like extending inboard from the injection molded cover member, forming a step ridge or like configuration.
