Abstract: A cooling system for electrical and electronic devices for hot swapping of a fan module without affecting cooling efficiency due to air backflow, preventing stalling of newly installed exhaust device due to reverse rotation. A check valve assembly having an inlet side frame member, an outlet side frame member, and one or more non-symmetrical valve flaps, each flap having a movable part and a fixed part. The outlet side frame allows the flaps to open under suction pressure on side of the outlet side frame, the inlet side frame disallows the flaps to open under suction pressure on side of the inlet side frame, allowing air to flow in one direction from inlet side frame side to outlet side frame side only. The check valve assembly can be independent of the exhaust device. The check valve assembly can prevent backflow of air during hot swapping of the exhaust device.

Abstract: The valve has a pair of mutually rotatable ceramic valve bodies within the bonnet that cooperate to allow a flow of water in one relative position and to block a flow of water in a second relative position. One valve body is engaged by the valve stem to rotate therewith while the second valve body is held fixed within the bonnet via radial projections that fit into recesses in the bonnet. An elastomeric ring of square cross-section is squeezed against the non-rotatable valve body by a spiral retaining ring that is positioned in a circumferential groove in the bonnet.

Abstract: A strained bilayer film with reinforcing members is used to open and close gas flow outlets in a microvalve array. The bottom layer of the bilayer film is compressive and the top layer is tensile. Reinforcing members are made from compressive material that accomplishes the dual objectives of reducing potential defects at the interface between the anchor region and the free region of the actuator, and controlling the stresses along the edges of the strained bilayer to avoid curling as the actuator unrolls from its normal coiled configuration in response to an applied voltage. Because of the configuration, the strained bilayer film occupies a minimal amount of space compared to other systems when the valve is opened, and it permits a higher density of microvalves to be utilized. Optional supports are provided over gas flow channel openings to increase the area over which the voltage is applied, increasing electrostatic stability of the actuators in maintaining their unrolled state for a variety of uses.
