Abstract: A battery module comprises: electrochemical cells arranged side by side in an array of multiple rows and columns, the electrochemical cells including terminals that comprise a first terminal at respective first ends of the electrochemical cells and at least portions of second terminals at the respective first ends; a housing that holds the electrochemical cells, the housing formed by a molding process with a polymer material; and a planar busbar extending along the terminals throughout the array, the planar busbar joined to the housing by an overmolding operation during the molding process without an adhesive between the planar busbar and the housing.

Abstract: A heat exchange unit for a solar photovoltaic panel comprising backing plate comprising U-channeling depressed in an upper surface thereof flexible tubing positioned within the U-channeling configured to carry fluid; and rear panel, the rear panel being positioned behind the backing plate, the rear panel having a reflective surface to reflect heat from the backing plate; wherein the heat exchange unit is configured to be positioned in thermal contact with a solar panel, with the flexible tubing between the backing plate and solar photovoltaic panel to facilitate heat exchange between the flexible tubing and the solar panel.

Abstract: An adjustable length bicycle mountable hand pump. The pump includes a barrel having an internal cylinder within which a piston is reciprocatingly moveable. A piston rod connects to a piston at a proximal end and to a handle at a distal end. The handle is selectively, longitudinally, adjustably lockable relative to the barrel. The end of the handle is contoured to mate with a bicycle frame member. A head having a contoured portion mates with an opposing spaced bicycle frame member.

Abstract: A portable backpack workstation for holding tools and the like. The backpack includes a self-supporting rigid frame and a shell defining a body having a top, a bottom, a back and left and right wing panels. The left and right wing panels are movable between an open position and a closed position. A pair of shoulder straps are secured to the back of the body.

Abstract: A foldable tool kit having a body constructed of a single elongate member to which is secured a plurality of individual tools pivotally movable about a pin between a folded position and a working position.
