摘要:
An improved power manager includes a power bus (410) and multiple device ports (1-5), with at least one device port configured as a universal port (3 and 4) to be selectively connected to the power bus over an input power channel that includes an input power converter (510) or over a output or universal power channel (412, 416) that includes an output power converter (440, 442). The universal power channel (412) allows the input port (4) to be selected as an output power channel instead of an input power channel (i.e. operated as a universal port) for outputting power to device port (4) over power converter (440). The improved power manager (500) includes operating modes for altering an operating voltage of the power bus (505), to minimize overall power conversion losses due to DC to DC power conversions used to connect non-bus voltage compatible power devices to the power bus.

A gas separation unit 102, 200, 300 for permeating a gas out from a pressurized feed mixture includes an input manifold 104, 204, an exhaust manifold, 106, 206 and a permeate assembly 108, 208, 303. The permeate assembly supports one or more permselective foils 130, 132, 218, 232, 318 over a hollow cavity 134, 272, 306 supported by a microscreen element 142, 144, 228, 230, 326. The microscreen element includes non-porous perimeter walls 190, 192, 278 supported on a frame surface and a porous central area 194, 280 supported over the hollow cavity. A porous spacer 138, 140, 174, 234 disposed inside the hollow cavity structurally supports the entire microscreen surface spanning the hollow cavity while also providing a void volume for receiving fluid passing through the porous central area and for conveying the fluid through the hollow cavity.

The present invention provides, among other things, 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 external manifolds which deliver reagents and/or coolant to one or more reactant or coolant flow fields of the membrane cassettes. In particular, the present invention describes the insert molding method, whereby the plenums of the external manifolds are created during the stack encapsulation step. The invention describes several methods for creating the manifold runner geometry via insert-molding, machining, or with separate components.

Various aspects of invention provide portable power manager operating methods. One aspect of the invention provides a method for operating a power manager having a plurality of device ports for connecting with external power devices and a power bus for connecting with each device port. The method includes: disconnecting each device port from the power bus when no external power device is connected to the device port; accessing information from newly connected external power devices; determining if the newly connected external power devices can be connected to the power bus without power conversion; if not, determining if the newly connected external power devices can be connected to the power bus over an available power converter; and if so, configuring the available power converter for suitable power conversion.
摘要:
This invention relates generally to filtration cassettes, and, more particularly to methods of fabricating cross-flow filtration cassettes. Cassettes of the invention are characterized, in part, by a series of sealing channels which selectively seal the filtrate and retentate ports to prevent undesired flow. The sealing channels have formed barriers on either side thereof which create side-walls for precisely controlling the flow of the sealant during the cassette formation. Filtration cassettes of the present invention can be manufactured from conventional membrane and flow screen components and can utilize both injection molding and vacuum assisted resin transfer molding fabrication processes.

摘要:
An electronics device carrier for porting a battery powered electronic device is formed by outer walls surrounding a hollow volume. The electronic device is held within the hollow volume and can be operated without removing the electronic device from the carrier. An input interface comprising interface elements external to the outer walls provides an element suitable for interfacing with external power devices such as a power source or another power load. A device interface includes interface elements at least partially disposed internal to the outer walls for interfacing with the electronic device battery. A charge controller is disposed between the input interface and the device interface and is operable to connect elements connected to the input interface to the device battery to either recharge the device battery or use the device battery as a power source.

Methods and systems for hydrogen generation from solid hydrogen storage compositions which generate hydrogen in an exothermic reaction wherein the heat released can be absorbed by solid endothermic compositions are disclosed. The solid hydrogen storage compositions comprise mixtures of chemical hydrides and water surrogate compounds. Fuel cartridges suitable for use with compositions which generate hydrogen upon the application of thermal initiation and methods for operating the fuel cartridges are also disclosed.
