Abstract: A fuel cell is operatively connected to, and powers an electronic device. The fuel cell includes at least one electrode and an electrolyte in electrochemical contact with the electrode(s). A mechanism is provided for delivering fuel to the fuel cell while powering the electronic device.

Abstract: An ink supply station for use with a first ink supply and a second ink supply includes a first module and a second module releasably coupled to the first module. The first module includes a first chassis and a first movable member supported by the chassis, wherein movement of the member causes flow of ink from the first ink supply. The second module includes a second chassis and a second movable member supported by the second chassis. Movement of the second member causes flow of ink from the second ink supply.

Abstract: A hydrogen generating apparatus includes a chemical container, a tubular member disposed at least partially in the chemical container, the tubular member having an inlet and an outlet, and a catalyst disposed within the tubular member.

Abstract: A fluid transport conduit for conveying ink-jet ink from a reservoir to a printhead in an ink-jet printer is provided. The fluid transport conduit comprises at least one inner layer, such as high density polyethylene, cyclic olefin copolymer, or polypropylene homopolymer, that is flexible and is a barrier to liquids, and at least one outer layer, such as nylon or polyvinyl alcohol, that is a barrier to air and is softer, or more compliant, than the inner layer, with the inner layer bonded to the outer layer. The two layers are advantageously co-extruded to form the fluid transport conduit.

Abstract: A rigid low cost chassis structure for a wide print media thermal ink jet plotter wherein the carriage slider rods are straightened and held in precise position relative to the platen roller during assembly of the chassis parts and operation of the plotter by using an extruded rigid support beam and a pair of rigid endplates and connecting structure which positions and holds the slider rods.
