Abstract: A system for delivering a supply fluid stream to a fuel cell stack that discharges an unused fluid stream is provided. A fuel supply is adapted to provide a pressurized supply fluid stream. An expander is in fluid communication with the fuel supply and is configured to receive the pressurized supply fluid stream to reduce the pressure of the pressurized supply fluid stream and to generate mechanical energy in response to reducing the pressure of the pressurized supply fluid stream. An electric machine is operably coupled to the expander and for selectively converting the mechanical energy generated by the expander into electrical energy. A compressor/blower is capable of being driven by at least one of the mechanical energy and the electrical energy to control the flow of the unused fluid stream to the fuel cell stack for recirculating the unused fluid stream back to the fuel cell stack.

Abstract: Embodiments relating to methods, processes and systems for measuring progesterone are provided. In particular, methods permit measurement and quantification of synthetic and/or endogenous progesterone from a progesterone-containing blood fluid sample by measuring a progesterone carbon isotope ratio by mass spectrometry and calculating the fraction of synthetic progesterone in the sample from the isotope ratio. Also provided are methods of evaluating bioequivalence of a synthetic progesterone composition using any of the methods provided herein. In an embodiment, methods of precise measurements of plasma levels are described for detection of progesterone analytes such as total progesterone, endogenous animal progesterone, and synthetic progesterone. Correcting for fluctuations in endogenous progesterone levels following application of synthetic progesterone allows a significant reduction in the number of test subjects required to evaluate bioequivalence of a synthetic progesterone composition.

Abstract: Adherent fabric articles and uses therefor are disclosed and described. In one aspect, an adherent fabric article may include a fabric layer bonded to a cling layer. In use, the fabric layer can be used to clean, polish, or treat a surface of a device, such as a scratch sensitive surface. Once cleaning, polishing, or treating is complete, the adherent fabric article can be stored on the device by adhering it to a smooth surface on the device using the cling layer. Moreover, in this position, the article may be used to protect the surface of the device to which the article is adhered. Further, the fabric portion of the article may be imaged to allow the article to be decorative in nature when adorning a device, or to provide messaging or advertisement.

Abstract: A method for diagnosing faults in a particular device within a fleet of devices is provided. The method comprises receiving performance data related to one or more parameters associated with a fleet of devices and processing the performance data to detect one or more trend shifts in the one or more parameters. The method then comprises detrending the one or more parameters to derive noise-adjusted performance data related to a particular parameter associated with a particular device. The method further comprises generating a fleet-based diagnostic model based on trend patterns and data characteristics associated with the fleet of devices. The fleet-based diagnostic model comprises one or more fuzzy rules defining one or more expected trend shift data ranges for the one or more parameters associated with the fleet of devices.

Abstract: A modular fuel cell power system includes a coolant source, a reactant source and a plurality of fuel cell modules. Each of the fuel cell modules includes a fuel cell stack and a fluid distribution plant in fluid communication with the reactant source, coolant source and fuel cell stack. The fluid distribution plant controls the flow of reactant between the reactant source and fuel cell stack. The fuel cell stacks are configured to be selectively electrically connected.

Abstract: A monitor for monitoring the concentration of oxygen in a fuel or in an ullage over a fuel comprises (i) a sensing element comprising a luminescent substance comprising a luminophore and a support in which the luminophore is covalently bound to the support, (ii) a light source arranged to irradiate the sensing element with light, and (iii) a photosensor arranged to detect light emitted from the luminescent substance. The luminescent substance may be, for example, a platinum porphyrin covalently bound to silica.

Abstract: A system for delivering an input fuel stream to a fuel cell stack to generate electrical current and to discharge an unused fuel stream is provided. A supply produces a supply fuel stream. An ejector combines a purged fuel stream and the supply fuel stream and controls the flow of the input fuel stream to the fuel cell stack. A purging arrangement receives the unused fuel stream which includes impurities and purges the impurities from the unused fuel stream to generate the purged fuel stream. A bypass valve is capable of delivering the purged fuel stream to the ejector. A blower is capable of delivering the purged fuel stream to the ejector. A controller controls one of the bypass valve and the blower for delivering the purged fuel stream to the ejector based on the amount of electrical current generated by the fuel cell stack.

Abstract: The present invention is directed to a mucoadhesive delivery system for the local or systemic administration of a pharmaceutical agent. The delivery system of the invention effectively and facilely enables transport of the pharmaceutical agent through mucosal membranes and into the vasculattire of the mucosa. The delivery system includes an at least partially water soluble bioadhesive layer and an at least partially water soluble backing layer. Incorporated within either or both of these layers are the pharmaceutical agent and a mucosal penetration enhancing agent. The mucosal penetration enhancing agent displays localized tissue irritation properties. The mucoadhesive delivery system may be in the form of a gel, film, disc or patch. It may be applied to any mucosal membrane of a patient including but not limited to those of the buccal and nasal cavities, throat, eye, vagina, alimentary tract and peritoneum.
