Abstract: A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.

Abstract: The continuous fluid delivery systems includes a fluid pumping device comprising a pump housing comprising a base member with a plurality of inlet ports and at least one outlet port and at least two pairs of opposing pistons movably associated with the housing. Each pair of opposing pistons at least in part defines a respective pumping chamber of the fluid pumping device. The pistons in each pair of opposing pistons may be independently controlled such that any one of the plurality of inlet ports or the at least one outlet port is independently selectable to be in fluid communication with one of the respective pumping chambers. A drive system may be interfaced with the respective pistons to at least reciprocally operate the pistons relative to the base member. The pump housing and the at least two pairs of opposing pistons may comprise a disposable unit.

Abstract: A hollow conduit, being primarily round, or having n sides wherein n is greater than or equal to three, and process for making the conduit is described herein. The hollow conduit is comprised of a polymer inner conduit having a pair of opposed ends and an interior and exterior surface. An overmolded corrugated polymer is bonded between at least a portion of the ends and at least a portion of the exterior surface of the inner conduit. The overmolded polymer has at least one flexible position retaining means at least partially embedded within. The flexible position retaining means within the overmolded polymer may be a metallic wire. The inner conduit may be a thermoset, and the overmolded corrugated plastic may be a thermoplastic.

Abstract: The invention described herein pertain generally to a process by which an injection overmolded profile may be materially bonded to a previously crosslinked profile.

Abstract: An electrophotographic image forming apparatus comprises a drive roller having a textured finish with a plurality of microscopic protrusions and a plurality of microscopic depressions; the drive roller comprising a shaft and a surface coating on the shaft; a flexible belt having a first hardness driven by the drive roller, the belt moving at least one of a toner image or a recording media having a toner image thereon; with the surface coating comprising a base compound and plurality of grit particles having a second hardness which is higher than the first hardness. The grit coating may advantageously have a thickness of not more than about 50 microns. The grit particles may comprise one or more ceramics, or one or more polymer compounds, or other materials. The drive roller advantageously has a coefficient of static friction of at least 0.5 with the belt.

Abstract: An air tunnel diverter for a refrigeration unit includes one or more leg members secured to a hub. The hub is generally formed to include a fitting through which cooler air is passed to the leg member and routed into the desired locations within the refrigerated space. The leg member is placed on the fitting by sliding one end of the leg member onto a leg portion of the fitting. The fitting is then secured to the leg member by an overmolding process in which a soft flexible plastic is cast or otherwise applied around the connection. Installation is further simplified by providing the leg member with a flexible portion. The air tunnel diverter is preferably secured in the refrigeration unit by foam insulation.
