Abstract: A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. Systems incorporating the Venturi device in which the primary flow path is charged with energy in the form of thermal energy from the ambient environment through the flow-induced vortex formation. Supercharger systems incorporating the Venturi device, wherein the primary flow of air into an engine is compressed with exhaust gases recirculated through the secondary flow path.

Abstract: A microfluidic sealing valve 1 comprises a primary channel 2, a valve channel 4, and a geometry that permits liquid in the primary channel 2 to flow into the valve channel 4 through an inlet 5. Liquid in the primary channel 2 is inhibited from flowing through a first port 8 into the void volume 7. A meniscus 9 moved by a flow of liquid in the primary channel 2 is restrained at the first port 8. A flow of liquid through the primary channel 2 generates a capillary force that causes the flow of liquid to flow into the valve channel 4. A capillary force generated by the flow of liquid through the valve channel 4 causes the meniscus 9 to expand from the first port 8 into the primary channel, to inhibit flow of liquid in the primary channel 2 past the first port 8.

Die Erfindung betrifft darüber hinaus auch ein Verfahren zum Abscheiden von Schichten auf einem Substrat bei einer derartigen Vorrichtung. Um die laterale Homogenität der abgeschiedenen Schicht zu verbessern wird vorgeschlagen, dass die mittlere Strömungsgeschwindigkeit (Ʋm) in der Förderleitung (9) so gewählt wird, die Förderleitung (9) derart gestaltete Diffusionsbeeinflussungsmittel (25) aufweist oder am dem Gaseinlassorgan (10) zugewandten Ende der Förderleitung (9) eine Druckbarriere (20) derart vorgesehen ist, dass in der Förderleitung (9) eine in die Querschnittsmitte der Förderleitung (9) gerichtete, ein laterales inhomogenes Schichtwachstum verursachende, entmischende Diffusion der organischen Moleküle zumindest gehemmt, bevorzugt verhindert wird.

Abstract: Electroaerodynamic devices and their methods of operation are disclosed. In one embodiment, ions are formed by dielectric barrier discharge using a time varying voltage differential applied between a first electrode and a second electrode. The ions are then accelerated in a downstream direction using a second voltage differential applied between a third electrode and the first and/or second electrodes, where the third electrode is located down stream from the first and second electrodes. The ions may then collide with naturally charged molecules and/or atoms within a fluid to accelerate the fluid in the downstream to create an ionic wind and an associated thrust.

Abstract: A fluid control system includes a deformable surface that covers a body in at least a first and second direction. The first direction is orthogonal to the second direction. The deformable surface includes a bottom side that faces the body and a top side that is opposite the bottom side. The fluid control system also includes at least one deformer between the deformable surface and the body. The at least one deformer is configured to modify a boundary layer of a fluid that is flowing over the deformable surface by selectively deforming the top side of the surface.

Abstract: An electrowetting-based droplet actuator includes top and bottom substrates, a droplet-operation gap between the top and bottom substrates, the droplet-operation gap including a gradually-reduced gap height in a direction of droplet flow when in use, and spaced electrodes embedded in the bottom substrate spanning a region thereof corresponding to the gradually -reduced gap height. A method includes gradually reducing a gap height in section(s) of a droplet-operation gap between top and bottom substrates of an electrowetting- based droplet actuator, the gradually reducing being in a direction of droplet flow when in use from a large-gap inlet to a small-gap outlet (relative sizes), the large-gap inlet being larger in height, the bottom substrate including spaced electrodes embedded therein spanning a region of the bottom substrate corresponding to the gradually reduced gap height, and moving dispensed droplet(s) of liquid in the direction of droplet flow using the spaced electrodes and an applied voltage.

Abstract: Wavy riblets are disposed at one or more auditorily important acoustical boundary layers of a sound producing device. Wavy riblets can be deployed directly onto the surface of the device, and/or onto a film or other carrier that is then positioned in or on the device. Wavy riblets can be advantageously deployed in sets, in a herringbone pattern, and sets of smaller riblets can be disposed between sets of larger riblets. Wavy riblets can also be superimposed onto other wavy or non-wavy riblets. Contemplated sound producing devices include speakers, musical instruments, fan blades and ducts.
