Abstract: Method and system for electrochemically compressing hydrogen. In one embodiment, the system includes a membrane electrode assembly (MEA) that includes a polymer electrolyte membrane (PEM), an anode, and a cathode. First and second gas diffusion media are positioned adjacent the cathode and anode, respectively. A humidifying membrane is positioned next to the second gas diffusion medium on a side opposite the anode. A water supply is connected to the humidifying membrane, and a hydrogen gas supply is connected to the second gas diffusion medium. A hydrogen gas collector including a back pressure regulator is connected to the first gas diffusion medium. Separators, positioned on opposite sides of the MEA, are connected to a power source. In use, hydrogen is electrochemically pumped across the MEA and collected in the hydrogen gas collector. The PEM is kept properly humidified by the humidifying membrane, which releases water into the second gas diffusion medium.

Abstract: A graphical workflow definition and management tool enables administrators and other authorized users to implement a workflow process that can be used to evaluate project submissions or other applications that require step-by-step process completion. The steps required to navigate through the workflow are first defined. Inputs, outputs, and actions, including conditional criteria, can be specified for the steps. The flow of control between the individual steps in the workflow is mapped out; changes to the status of a project submission can cause a submission to migrate to a succeeding step in the workflow. A “sandbox” testing environment allows changes to any aspect of the workflow to be safely evaluated without affecting live data. Conflicts between production and test workflows are identified and intelligently resolved.

Abstract: A novel razor cartridge includes at least one non-cutting element disposed anywhere within a blade array between a guard and a cap and/or in a blade position of a frame providing skin/hair management. This non-cutting element allows the fine-tuning of parameters such as blade-skin contact, hair orientation, blade spans and rinse-through gaps in manners that improve shaving comfort, closeness, efficiency, and/or rinse-ability. The non-cutting element may include projections, fin-like elements, comb-like features having teeth, exfoliation or lubricating capabilities. By having a fixed non-cutting element disposed midway in a blade array, a multi-stage cartridge is provided with a middle control point with potentially different functionality before and after the non-cutting element. The non-cutting element is not attached to another blade in the blade array though it may be manufactured as a modified blade support, attached to a blade support, or as part of the frame or the clips.

Abstract: A mounting head, a system incorporating the mounting head and a support such as a monopod, and a system including the mounting head, the monopod, and a camera enable a photographer to tilt a monopod or other camera support while maintaining a substantially level horizon of an image. An upper head assembly and a lower head assembly are connectable to the camera and the monopod respectively. The assemblies are interconnected by a universal joint which allows the upper assembly to remain level as roll and pitch vary. A resilient member dampens relative motion of the head assemblies. As a photographer moves the camera to capture a scene, force is transmitted from the photographer's hands via the mounting head through the monopod. The photographer maintains a level horizon as the monopod tilts. A test apparatus enables design of a resilient member for desired interaction with selected classes of equipment.
