An apparatus and method of circulating a heat-absorbing material within a heat exchanger. The apparatus comprises a manifold layer coupled to an interface layer. The manifold layer comprises an inlet manifold and an outlet manifold. The interface layer comprises a plurality of channels that extend from the inlet manifold, toward a heat-exchanging plane, and turn away from the heat-exchanging plane, terminating at the outlet manifold. The plurality of channels are stacked in a plane non-parallel to the heat-exchanging plane. Each of the channels is adjacent to another, thus allowing heat radiated from a heat-generating device to be conducted to a cooling material circulating within the channels, away from the heat-generating device. Preferably, each of the channels has a U-shape or an elongated U-shape.

A rearview mirror system comprises a spotter mirror for providing an image of an object in a vehicle's blind zone to the vehicle's operator. A recognition enhancement device is provided with the spotter mirror for drawing the attention of the driver to the spotter mirror when an overtaking vehicle enters the driver's blind zone. The signaling display is activated by a sensing system which senses the presence of the overtaking vehicle in the blind zone. An electrochromic element is incorporated into the spotter mirror to reduce the intensity of light transmitted from the object and reflected from the spotter mirror. Activation of the electrochromic element to darken the spotter mirror will induce the operator to observe the object in the spotter mirror.

Combination of injector-ejector for fuel cell systems
ActiveUS7320840B2Efficient drawingReactant parameters controlCell component detailsHydrogenFuel cells
A fuel cell system including a combined injector / ejector system. The pressure of a hydrogen gas being injected into the fuel cell system by the injector acts as a pump that draws an anode exhaust gas being carried by the ejector back into the fuel cell system. The respective gases mix together in proximity to the ejector prior to being introduced back into the fuel cell system. A pressure controller can be provided to control the pressure of the hydrogen gas applied to the injector to more effectively draw the anode exhaust gas. In this manner, the need for a separate pump for the ejector, and the energy required for its operation, is eliminated or at least lessened, thus increasing the overall energy efficiency of the fuel cell system.

An apparatus and method for hydrocarbon recovery in a well for coal bed methane (CBM) recovery, tight sand gas extraction, and other gas extraction techniques provides for the formation of a hydrocarbon foam comprised of a fluid delivered into a downhole portion of the well and the hydrocarbon, maximizing water removal for gas recovery. The apparatus may include a check valve that feeds a nozzle to deliver or atomize the spray of fluid into the downhole portion of the well when the pressure applied to the fluid is sufficient to overcome a hydrostatic pressure in the downhole portion of the well and to deliver the fluid into the downhole portion of the well. The fluid is not sprayed directly into the formation, thereby protecting the formation from damage and recovering the fluid even in the case where water is not present. The capillary tube feeding the fluid to the check valve may be placed externally to the production tube to facilitate ease of cleaning and clearing of the production tube.

Marine water drop muffler
ActiveUS20100255738A1Efficiently transitionMaximize generationExhaust apparatusPropulsion power plantsExhaust gasSurface function
A water drop muffler for use in a marine exhaust system to silence exhaust noise while separating entrained water from exhaust gas using hydro-dynamic centrifugal separation principles enhanced by turbulent flow. A muffler housing has a top and a bottom, and defines an internal volume bounded by a generally vertically disposed cylindrical inner surface formed about a longitudinal axis. A generally tubular exhaust inlet is disposed in generally tangential relation with the cylindrical inner housing surface for receiving a mixture of exhaust gas and entrained cooling water. A variable geometry flow channel efficiently transitions the flow for discharge through a vertically elongate opening disposed along the length of the housing inner surface thereby creating vortex flow within the housing to maximize the generation of centrifugal forces. The vortex flow formed within the housing causes the relatively heavy water droplets and water vapor (i.e. steam) to be drawn away from the housing axis toward the cylindrical inner surface. In addition, turbulent boundary layer flow along the surfaces of the variable geometry flow forming channel and the other housing surfaces functions to more efficiently draw entrained water droplets and steam into contact with various surfaces within the housing thereby causing water to coalesce along the inner housing surfaces.
