An oil scavenge system includes a tangential scavenge scoop and a settling area adjacent thereto which separately communicate with a duct which feeds oil into an oil flow path and back to an oil sump. A shield is mounted over the settling area to at least partially shield the collecting liquid oil from interfacial shear. A multiple of apertures are located through the shield to permit oil flow through the shield and into the duct. The scavenge scoop forms a partition which separates the duct into a first portion and a second portion. The first portion processes upstream air / oil mixture that is captured by the tangential scoop while the second portion receives the oil collected in the settling area.

Broadcast messages are efficiently directed to nodes of an overlay network. Broadcast messages include an End ID parameter specifying the range of key values for nodes that should receive the broadcast message. Each node of an overlay network maintains a list of finger nodes and their respective key values. Upon receiving a broadcast message, a node assigns a finger node a new End ID value based upon the End ID value of the broadcast message or the key value of an adjacent finger node. The node compares a finger node's new End ID value with the finger node's key value to determine whether to forward the broadcast message to that finger node. A broadcast message forwarded to a finger node includes an End ID parameter equal to the new End ID value determined for the finger node. Nodes can aggregate response messages from its finger nodes.

The optics system is a lamp assembly which produces the desired beam pattern by using a reflector, a lens, a retainer lens, and an LED as a light source. The lamp assembly has three main components (the reflector, the lens, and the retainer lens) that maintain proper alignment between the light source and the reflector, the lens, and the retainer lens. The optical system collects substantially 100% of the light from the light source while effectively shaping the beam pattern using both cylindrical and revolved reflector elements. The lens has a saddle-shape which is used with the surface of a revolution to eliminate any “dogbone” light pattern shape. The use of a reflective element forms the foreground of the beam pattern.

The invention provides a directional back-light arrangement for an auto-stereoscopic display in which different parts of the backlight arrangement point in different directions. This means that different parts of the backlight arrangement will be suitable for directing images in different directions, while reducing the effect of optical aberrations resulting from large exit angles.

A centrifugal blower with forward curved fan blades includes an inlet shroud whose shape is specifically designed for creating a smooth incoming airflow pattern that leads into the inner leading edges of the fan blades. The inlet shroud has first and second curved surfaces, wherein the centers of curvature of the two surfaces lie in the same plane, and the center of curvature as well as the radius of curvature of one curved surface is greater than that of the other. At least one center of curvature lies beyond the outer diameter of the impeller, and at least one center of curvature lies beyond the impeller's inner diameter, wherein the impeller's inner diameter is defined by the inner leading edges of the fan blades. Performance benefits are achieved when a forward curved blower with such an inlet shroud operates with a flow coefficient of between 9 and 52.

A respiration hood assembly is effected from a thin-walled headpiece nested within the periphery of a mating exterior housing that includes a filtered aperture. The nested engagement between the headpiece and the housing is also useful in capturing one edge of a plastic membrane skirt that is thus suspended to drape over the person wearing the headpiece. A battery powered electric fan is deployed within the housing to draw ambient air through the vent aperture into the space shrouded by the skirt. The nested headpiece arrangement is useful in retaining other fibrous towels or tissue to extend the usefulness of the assembly and a parallel connection is provided to a motor vehicle battery to extend the period of electrical excitation.

Light guides are formed above each light receiving element. These light guides are made of a high refractive index material, and surrounded by a material of lower refractive index. The light guides are each made up of a light introduction region leading with a constant width from a light entrance surface, and a tapered reduced region leading from the light introduction region to a light exit surface. The light introduction region totally reflects the incident light toward the reduced region. The reduced region, owing to its tapered shape, surely directs the light onto a light receiving element, and prevents the light from entering charge transfer paths around the light receiving element.

An optical system with an LED light source utilizes a base with an inverted conical shape to conduct light to a phosphor layer. The phosphor layer emits light from both upper and lower surfaces. The base and a substantially mirror image cap element facilitate efficient extraction of the phosphor-generated light from the optical system so that the output of the system is omni-directional light suitable for common lighting applications. The system is very efficient in that nearly all the light generated by the LED is transmitted to the phosphor layer, and nearly all the light emitted from the phosphor layer is output from the system.

An optical system that collects 100% of the light emitted from the light source and effectively directs it into the desired beam pattern. This is achieved by a combination of different optical control methods including reflector and lens optics. The cost is controlled by a design that reduces the optical part count to 2 main components, which reduces manufacturing and assembling time and maintains proper alignment to the light source and system.

A light control film providing improved n front luminance and appropriate light diffusion, without problems of interference pattern, glare etc., has a rough surface constituted so that, for a curved surface portion of the rough surface, having an approximately square area of 1 mm2 or larger and defined at an arbitrary position on the rough surface by using data for heights of the rough surface measured at predetermined intervals in the longitudinal and transverse directions, an average of slopes of the curved surface portion (θnv degrees) of the rough surface, with respect to a base plane of the film, should be not less than 27 degrees and not more than 70 degrees at substantially any position on the light control film.

A wearable device for measuring the light conditions of a subject includes a light sensor for measuring said light conditions, and a light guide for collecting incoming light and directing it to said light sensor. A software application is also provided executable on a remote device and configured for receiving data from the wearable device via a receiver on the remote device, processing the data by means of the remote device to provide data representing the light exposure of the subject wearing the wearable device, and displaying at least a part of the data on a screen of the remote device.

A skydiving helmet includes a lens for protecting the face of a skydiver during a skydiving event. An air-intake hole is formed on the helmet, and an airflow deflector plate is positioned against the air-intake hole. Thus, the deflector plate directs air over the inside surface of the lens to prevent fog from forming on this surface during a skydiving event.

A commercial tomato strainer attachment includes a hopper having open top and bottom ends and a downwardly converging wall. The bottom end has a cylindrical shape and a smaller diameter than the top end. A bottom support member is coupled to the hopper bottom end and has a cavity vertically aligned therebeneath. A drive shaft extends through the cavity and has a helical blade traveling along a major length thereof that is partially seated within the bottom support member. The blade radius decreases from a proximal to a distal end thereof. A universal coupling is mounted to the support member exterior surface. The proximal drive shaft end and the coupling are attachable to a commercial mixer. The hollow chamber is coupled to the bottom support member, houses a major length of the blade and the drive shaft, and has a distal end for discharging tomatoes therefrom.

A recyclable continuous ink jet print head is provided that includes a manifold formed from a metal such as stainless steel, a die having ink jet nozzles formed from a ceramic material such as silicon, a control circuit connected to the die via microwiring, and an interposing member disposed between the manifold and the die. The interposing member is formed from a composite material such as Al—SiC having a coefficient of thermal conductivity that is higher than that of the silicon die, and a coefficient of thermal expansion (CTE) that is between that of the die and the manifold. During manufacture, the CTE value of the interposing member allows long-lasting, heat-cured epoxy compositions to be used to bond the die to the manifold and to encapsulate the microwiring between the die and a control circuit with while maintaining proper alignment of the die ink jet nozzles on the manifold. When the die wears out, the high thermal conductivity of the interposing member allows the die to be easily removed from the manifold, thereby facilitating re-cycling of the manifold.
