An infusion pump includes a housing with a door pivotally mounted to the housing, a tube channel on the housing configured to hold a tube in the infusion pump, a pumping mechanism including a shuttle, and a slide clamp ejection device.

Infusion pump with tube loading guidance and confirmation

A pressure sensing assembly for an infusion pump, including: a tubing guide arranged to receive tubing; a displaceable load assembly at least partially disposed within the tubing guide and with a first surface facing in a first direction; a load cell facing the load assembly in the first direction; and a displacement assembly engaged with the tubing guide, facing the first surface in a second direction, opposite the first direction, and exerting a first force on the load assembly in the first direction. The load cell is arranged to detect a second force, greater than the first force, acting on the load cell in the second direction.

Pressure sensing assembly and method for an infusion pump

A bead seal structure is disclosed for sealing between plates of a fuel cell system, wherein the bead seal structure militates against a leakage of fluids from the fuel cell system and a cost thereof is minimized.

Metal bead seal for fuel cell plate

A method for preparing a bipolar plate assembly for a fuel cell stack is provided. The method first includes the steps of providing a first unipolar plate having a first active area with a plurality of channels formed on a first inner surface thereof, and a second unipolar plate having a second active area with a plurality of lands formed on a second inner surface thereof. The first unipolar plate and the second unipolar plate are aligned to dispose the first active area adjacent the second active area. A first pressure is then applied to the first and second active areas to pre-nest the first active area and the second active area. The perimeters of the first and second unipolar plates are then joined. A clamping fixture and associated method for assembling the bipolar plate assembly is also provided.

Pre-nesting of the active area on plates to reduce thickness variation

A seal configuration is provided for a fuel cell stack, including a first bipolar plate and a second bipolar plate, each disposed on opposite sides of a membrane electrode assembly. The seal configuration includes a first sub-gasket adhered to a recess region of the first bipolar plate and a second sub-gasket adhered to a recess region of the second bipolar plate wherein the first and second sub-gaskets are disposed on opposite sides of the membrane electrode assembly. A seal member is disposed in the recessed regions of the first and second bipolar plates and between the first and second sub-gaskets. The seal configuration minimizes the size of the bypass regions around the seal perimeter and provide better control of the positions of all components during assembly of the fuel cell stack. The approach also reduces sensitivity to ambient relative humidity variations and reduces manufacturing costs by eliminating the need for humidity control in the production area.

Seal configuration for fuel cell stack

The present invention is directed to mitigating overuse of limited membrane regions in electrochemical conversion assemblies, particularly under cold start conditions. In accordance with one embodiment of the present invention, the anode and/or cathode flowfield plates of an electrochemical conversion assembly are configured such that the fluid header region defines an anode fluid header, a cathode fluid header, and a coolant fluid header configured such that a feed region of the plate defines an array of substantially linear fluid channels extending from an acutely angled header/feed interface defined on the plate to a feed/active interface defined across the entire active area of the plate.

Enhanced flowfield plates

The present invention discloses a stamped bridge member that defines a flow path between a header and a flow field on a fuel cell plate. The bridge member provides a support surface on which a seal can be positioned to seal the plate against adjacent plates or MEAs. The fuel cell plates can be stamped plates with two surfaces each having flow fields thereon. The flow fields maintain a fluid flowing between a supply header and a return header on a single surface of the plate. The ends of the flow fields can taper relative to the supply and return apertures to provide for a desired flow distribution through the flow field.

Stamped bridges and plates for reactant delivery for a fuel cell

Apparatus is disclosed for producing thin polymeric film and includes a source (17) of a solution of polymer and solvent; a casting member (10) having an outer surface (12) for receiving a cast layer (18) of polymer and solvent, the layer having a transverse width; a casting die (16) for casting the layer of polymer and solvent onto the outer surface, the die including a transverse slot (20) with adjacent upstream and downstream lips (22, 24) between which the polymer and solvent flow during casting, the lips having lengths approximating the transverse width of the layer; and a device (11 ) for moving the outer surface past the casting die. Improved devices are provided for optically inspecting (26, 32) the lips to detect a presence of agglomerations of polymer on the lips; for directing a stream of solvent (28, 34) at the lip to wash away any detected agglomeration; for supporting (58, 116) the device for inspecting and the device for directing; and for traversing (44, 48, 52, 64; 90, 96, 106, 120) the device for supporting back and forth along the length of the lip to facilitate inspecting and washing of the lip.
