Abstract: The present invention provides an assistive mobility device convertible between a rollator mode and a transport chair mode.

Abstract: A cooling assembly includes an evaporator containing a primary cooling medium, a passive condenser, and a heat exchanger. When a secondary cooling medium is provided to the heat exchanger, the primary cooling medium in the gas phase switches from being received by the passive condenser to the heat exchanger without operating any valves located between the evaporator and the passive condenser and between the evaporator and the heat exchanger. The primary cooling medium circulates between the evaporator and the passive condenser and between the evaporator and the heat exchanger by natural circulation and gravity without a pump in the flow path of the primary cooling medium between the heat exchanger and the evaporator and between the passive condenser and the evaporator to circulate the primary cooling medium.

Abstract: A latching valve assembly which controls the flow of air and purge vapor between a fuel module and a carbon canister, where a change in an electrical property of the latching valve assembly is used to detect whether the latching valve is in the open position or the closed position. The latching valve assembly of the present invention eliminates the need for a physical switch solution, mechanical or non contact solutions, eliminates complexity of valve hardware requirements, and only adds minor electric components and software to identify the latch position. This system eliminates valve complexity and mechanical connections required for electrical conductivity.

Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

Abstract: Methods of treating hemorheologic abnormalities in mammals are provided, as well as methods of evaluating circulatory flow mechanics by analyzing hemorheologic determinants or hemorheologic abnormalities in the blood.

Abstract: An illuminator (1) has two lines of LEDs (2) on inwardly-directed faces (7) of an elongate body (3) which forms a mullion for a display cabinet. Heat conduction through the body (3) to outer surfaces provides the durable effect of anti-sweat heating to prevent condensation in doors of the cabinet.

Abstract: Fastenings, including stretchy or flexible “zebra-like” and “leopard-like” appearing materials, are disclosed having spaced bands or a distribution islands of molded loop-engageable hooks or molded pre-forms for hooks, between which are bands or regions of different character. Molding is by rigid molds filled from the base region of the stems. In embodiments, linear bands or islands of fastener elements are themselves inextensible in the direction of their extent and comprise multiple rows of fastener elements. For ease of forming a uniform, elastically stretchy or flexible product, the bands or islands of fastener elements extend in the machine direction during manufacture.
