Abstract: Various embodiments include a child resistant and senior friendly dispenser. The dispenser can be used to hold or retain medicine such as, for example, pills. The dispenser can include a bottle and a bottle cap. The cap can restrict access to the contents of the bottle based on one or more incorporated child resistant features. The cap can include a base and a lid. The base can be coupled to a top portion or neck of the bottle to secure the cap to the bottle. The lid can include one or more snaps for securing to the base when in a closed positioned. The base can include one or more corresponding recesses or slots for accepting and securing the snaps.

Abstract: The present set of embodiments relate to a system, method, and apparatus for hydrating and mixing a liquid medium from a dry medium. Such systems, methods, and apparatuses can be used in the biotech industry because they can be used to provide prepackaged dry media in a format that can be quickly rehydrated free of issues with operator error found in more conventional media rehydration systems using mixing tanks and reactors.

Abstract: The present invention provides membrane cassettes and stacks thereof which are suitable for a use in a variety of electrochemical applications. The invention further provides membrane cassettes which comprise one or more composite membrane electrode assemblies which have a peripheral gasket where the gasket has at least one groove or channel for introducing and distributing a sealant about the cassette. In certain preferred embodiments, the invention provides cassettes and stacks which are suitable for use in fuel cell applications.

Abstract: A device for recovering liquid droplets from a fluid flow stream including a rotatable element comprising wall elements configured to partially enclose a volume with an annular perimeter wall that includes an inside surface radially offset from and facing an axial center, a fixed base wall supports the rotatable element about the axial center, an input fluid conduit delivers the fluid flow stream into the fluid volume, means for rotating the rotatable element for generating a centrifugal force capable of forming a layer of liquid held by the centrifugal force against the inside surface, and an output liquid conduit disposed to collect liquid from the layer of liquid, wherein the layer of liquid rotates with the inside surface with a tangential velocity vector and the collection aperture is fixed in position opposed to the tangential velocity vector such that liquid in the layer of liquid enters the collection aperture.

Abstract: A device (150, 250) for recovering liquid droplets from a fluid flow stream containing the liquid droplets entrained therein includes a rotatable element (164, 256) formed with a partially enclosed fluid volume (184, 262). The fluid is injected into the partially enclosed fluid volume while the rotatable element (164, 256) is being rotated. The rotation generates a centrifugal force capable of moving liquid droplets deposited onto inside surfaces of the partially enclosed fluid volume (184, 262) to a perimeter wall inside surface (172, 284) and to hold a layer of liquid against the inside surface (172, 284). An output liquid conduit (208, 286) is formed to enter into the partially enclosed fluid volume (184, 262) and to position a collection aperture (212, 290) proximate to the inside surface (172, 284) for collecting liquid from the layer of liquid held against the inside surface (172, 284). The device (150, 250) is usable to recover liquid water from the outflow of a hydrogen fuel cell system (100).

Abstract: Purge systems and methods are disclosed for flushing unreacted materials and byproducts from a reactor. In one embodiment, the reactor houses a hydrogen generation catalyst and the system comprises a hydrogen generation fuel cartridge containing a reservoir that stores water which may be recovered from the exhaust of a fuel cell. The reservoir may comprise a flexible bladder or a piston-type configuration. Water is delivered from the reservoir to flush the reactor of any residual fuel and/or byproducts.

Abstract: A fuel cell power system including a removable hydrogen generation fuel cartridge module and method are disclosed. The fuel cell power system incorporates one or more of the following elements: a) a mechanism for fuel regulation which may be controlled by an auxiliary module; b) a means for heat exchange in communication with the reactor and/or the fuel cartridge body; c) an air filter for the incoming oxidant gas feed to the power module; d) a means to transfer mechanical energy from the power module to the fuel cartridge; and e) a means for heat exchange.
