The invention describes devices for controlling fluid flow, such as valves. The devices may include one or more electroactive polymer transducers with an electroactive polymer that deflects in response to an application of an electric field. The electroactive polymer may be in contact with a fluid where the deflection of the electroactive polymer may be used to change a characteristic of the fluid. Some of the characteristic of the fluid that may be changed include but are not limited to 1) a flow rate, 2) a flow direction, 3) a flow vorticity, 4) a flow momentum, 5) a flow mixing rate, 6) a flow turbulence rate, 7) a flow energy, 8) a flow thermodynamic property. The electroactive polymer may be a portion of a surface of a structure that is immersed in an external fluid flow, such as the surface of an airplane wing or the electroactive polymer may be a portion of a surface of a structure used in an internal flow, such as a bounding surface of a fluid conduit.

Virtual wall gas sampling for an ion mobility spectrometer

The presence of trace molecules in air may be determined using an ion mobility spectrometer. Such devices may be used in the fields of explosives detection, identification of narcotics, and in applications characterized by the presence of very low airborne concentrations of organic molecules of special interest. The sensitivity of such instruments may depend upon on the method of gas sampling utilized. A virtual wall gas sampling system can greatly improve the sampling efficiency, particularly when the sampling needs to be performed at a distance from the air intake and large volumes need to be sampled. The virtual wall gas sampling system consists of an intake gas flow and a separate group of one or more sheet-like gas flows, which may be either mutually deflected to move with a circular motion or may be formed into a cylindrical bounding surface.

Diffractive optical element that polarizes light and an optical pickup using the same

A first diffractive optical element pattern with a pattern pitch that is no greater than a wavelength of incident light is formed on a first main surface of substrate such as a glass plate. Second diffractive optical element patterns are formed at positions that are respectively incident to positive first-order diffracted light and negative first-order diffracted light produced by the first diffractive optical element pattern. Negative first-order diffracted light produced by each second diffractive optical element pattern is incident upon a boundary face of the substrate at an angle that is smaller than the critical angle, and so exits the substrate.

Accelerated ray-object intersection

An original mesh is provided with a bounding surface and a convex hull surface. A first tessellation links the convex hull to the original mesh, and a second tessellation links the bounding surface to the convex hull. Using the tessellations to find a first intersection between a ray and the original mesh by finding a first intersected polygon of the bounding surface, and then traversing adjacent intersected polygons starting from the first intersection until the intersection is found. When the ray is moved, a second ray-surface intersection can be found by finding a polygon locally near the first intersection and containing a first intersection with the moved ray, traversing out from the local polygon through adjacent polygons intersected by the moved ray, and determining whether traversed polygons are unoccluded based on whether they are part of the convex hull surface.

Damping bearing

A damping bearing (20) including an inner ball portion (34) attached to an end of a support shaft (32), and an outer collar portion (30) attached to a housing (22) for rotation of the housing relative to the support shaft about a center point. A chamber (28) for a damping fluid such as grease is defined by clearance between the end of the shaft and the housing. The fluid chamber has opposed bounding surfaces (29, 37) that are non-spherical about the center of rotation so that the chamber changes shape upon rotation of the bearing, thus shifting damping fluid across the chamber. The chamber may be a flat cylindrical void normal to a centerline (33) of the shaft. It may provide only enough clearance for less than ±10 of relative rotation between the housing and shaft. A set-screw (26) may pressurize the fluid in the chamber.

Method for modifying ABS plastic

The invention provides a modified method of ABS plastic. ABS aggregate and modified powder body which is easy to be eroded are mixed to obtain modified ABS. After the modified ABS plastic obtained by adopting the method is coarsened, the surface area is increased greatly, the hydrophilicity of the surface is strengthened, and the adhesive force of a coating after being plated is increased. The modified ABS plastic only requires shorter acid corrosion and coursing time (the acid corrosion and the coursing in this time cannot erode PC), and the ideal coarsening effect can be achieved. Coupling agent is used, the compatibility between the modified powder body and the ABS can be enhanced, and the fine compound bounding surface can be obtained; solvent can improve the operation effect of the coupling agent; dispersant agent can lead the materials to be mixed to be evener, thus the modified quality is improved.

The invention provides a system and method for turbulent flow drag reduction using discrete counter-rotating elements disposed adjacent a bounding surface and arranged to effectively disrupt or suppress stream-wise vortices and / or traveling waves thereby reducing turbulence and increasing fluid flow. In embodiments, the counter-rotating elements effectively decouple the interaction between traveling waves and stream-wise vortices. By using discrete counter-rotating elements as disclosed, the energy input to the counter-rotating elements is advantageously less than the energy gained from the flow rate increase. The counter-rotating elements may comprise e.g., counter-rotating strips, counter-rotating disks or a plurality of sequentially activated jets. In addition, the bounding surface may comprise a section or pipe, a substantially planar surface, etc. The counter-rotating elements may be used along a section of a pipe, on a surface of an aircraft wing, in HVAC systems, etc. Examples of fluids include, but are not limited to: water, air, natural gas, oil, etc.
