    摘要： A flow channel structure that includes a first inlet path for a first fluid, a second inlet path for a second fluid, a merging portion that merges, in the thickness direction of a substrate, the first fluid and the second fluid, a first merged fluid channel in which both fluids merged in the merging portion flow along a top surface of the substrate, a flow direction altering portion that causes the flow direction of the fluid flowing through the first merged fluid channel to change from the top surface side of the substrate towards the back surface side thereof, and a second merged fluid channel for changing the flow direction of this fluid to flow to the downstream side so that the fluid flowing from the first merged fluid channel through the flow direction altering portion flows along the back surface of the substrate.

    摘要： A compact fluidic circuit card having a main body with internal sensing elements and with fluidic circuit components (FCCs) located on both its front and back surfaces. An immunoassay sensing element may be used either in the form of a optical waveguide around which the liquid test sample may flow, or a disc through which the liquid test sample may flow. The card may be made inexpensive enough to be disposable by forming its main body and all of its FCCs so that they are suitable for being integrally formed in one piece by injection molding from plastic, regardless of the number of its FCCs; and by using thin strips of adhesively attached material for the main body's cover, needle septum strip and valve membrane strip. Heat-shrink plastic may be used for the valve membranes. The strength of the heat-shrink plastic's adhesive bonds may be increased by using a corona or plasma discharge to intentionally damage the surface of the heat-shrink plastic. Cross contamination between liquids in the card may be prevented by using separating bubbles, large radius turns in the channels, and valve cavities shaped to permit the valve membranes to empty them completely when the valve is closed. Mass transfer enhancing components may be provided to increase the rate at which the target material in the liquid test sample reaches the sensing element. Either transmissive or reflective light source and photodetector pairs may be used to detect fluids and bubbles in the card; and to read information encoded on the card.

    摘要： Water is mixed with fire suppressant polymer in a mixer absent a power source. The mixer receives water through a water inlet with water exhibiting high velocity and associated hydrodynamic force. Such velocity is achieved by locating the water inlet connected to a float or other part of an aircraft so that when the aircraft flies over water with the float dipping into the water, water is driven through the opening and into the water inlet of the mixer. A polymer inlet passes into the mixer. A bend is located downstream of the water inlet and the polymer inlet. The bend exhibits sufficient resistance to fluid flow direction therethrough that the polymer is sheared and thoroughly mixed and activated with the water. A colorant inlet is optionally provided within the mixer and the water and polymer mixture is then discharged into a tank for later utilization at a firefighting location.

    摘要： A fluid mixing method using a micromixing apparatus which includes a mixing microchannel having a channel length and a continuously variable channel width defined by a first sidewall surface and an opposing second sidewall surface. The channel width varies from a minimum channel width h to a maximum channel width H in a ratio of H:h≧1.1:1.0. A first inlet injects a first fluid and a second inlet a second fluid into the mixing microchannel which both flow in a flow direction in the mixing microchannel along the channel length. The first sidewall surface includes first curved surface portions and the second sidewall surface includes second curved surface portions. The first and second curved surface portions are non-overlapping to provide the variable channel width. The flow velocity profile is passively varied and exclusively controlled by the continuously variable channel width.
