Abstract: An insecticidal barrier (1) having an upper net part (2) with a mesh size preventing insects, for example mosquitoes, to transverse the barrier, the upper net part (2) having a first content of insecticide. In addition, the insecticidal barrier (1) has a lower part (3) with an insecticidal fabric, tarpaulin, foil, woven or knitted fabrics or non-woven, or net with a net material having a higher tear strength than the net of the upper part (2) in order to make the lower part (3) of the net more durable.

Abstract: A device and related method for mixing a powdered component and a liquid component with minimal user interaction are described. A powdered component and a liquid component are separately fed into a mixing chamber. The powdered component may be released into the liquid component by removing a barrier. Alternatively, the two components are drawn into the mixing chamber from respective sources by a vacuum. The mixture is sonicated at precise vibrational frequencies to control the physical properties of the final blended content. A piston-like device is used to remove the blended content from the mixing chamber.

Abstract: Male and female parts of a buckle have mating shapes which together form ears and depressed eyes of an animal face. The male part has the shape of an anchor with eyes which slide into grooves to lock the parts, and ears which project upward from a slot in the cylindrical female part. Hooks on the female part back secure a cord loop which extends from the female part. A cover snaps on the back of the female part.

Abstract: A high shear mixer in a holding tank is used in a continuous flow process. Flow rate of material into and out of the holding tank establishes residence time in contact with shearing elements. A batch shear mixer is used in a tank that has continuous flow into the bottom and out of the top. A level controller controls a valve or a positive displacement pump at the inlet. The mixing chamber is sized for the maximum needed residence time, slowing the flow increases the residence time. In an open tank lower inlet pump and upper outlet pump are coordinated. Incoming flow rate matches outgoing flow for continuous processing.

Abstract: A real-time in-situ sensor system is provided for measurement of bioluminescence and determination of bioluminescence surface signature. The system measures bioluminescence in the wake of a submerged moving object as well as ambient light levels outside of the wake. Along with measurements of depth and water-quality parameters including turbidity, temperature and salinity, the surface signature of the induced underwater bioluminescence can be calculated by considering light transmission and attenuation through water. With this real-time information, the operator of the submerged moving object can employ tactical maneuvers to affect the resultant surface signature.

Abstract: Playground device, for example a swing or a see saw, having a ground supported, movable part and at least one motion sensor configured for sensing the motion of the movable part. The motion sensor is functionally connected to a sound signal feedback generator that is configured for converting the signals from the motion sensor into a sound feedback in response to the motion of the movable part. The sensors are mechanically connected only to the movable part in order to provide system with a large number of variations of embodiments.

Abstract: Two plastic sheets are selectively joined to create parallel air cells with connecting passageways at alternate ends. The sheets form a mattress for full body, back or leg massages. An air pumped reservoir supplies air flow to a fluidic switch. Air from a right arm pushes air to a left leg and sequentially fills a first cell. Alternating passageways at opposite ends of cells sequentially fill the cells. After the last cell is filled, air flowing out from the last cell through a right arm of the switch pushes the supplied air flow to a right leg of the switch for exhaust, emptying the cells. The cycle repeats automatically, sequentially filling the cells and pushing blood toward the heart and then emptying the cells then sequentially filling the cells.

Abstract: A radar array linearly traverses an area of ground. Additional radar elements fore and aft of the array detect changes in elevation and orientation of the array. These elements act as a preview for the height changes due to ground variation. Any variation in height that is not detected by these fore and aft-mounted elements is thus due to variation in radar elevation and/or orientation and can be subtracted from the resulting data without introducing distortion. Correction factors are applied to the range data returned from each element in the array, which normalizes the data and makes it appear as if the array did not change orientation or elevation.

Abstract: Method for processing digital images, such as magnetic resonance images of a brain. The images contain a first object, for example the cerebrum white matter, a second object, for example the cerebral cortex, and a third object, for example the cerebrospinal fluid. The method involves providing a digital dataset representing a deformable curve or surface that in an initial state approximates the boundary between the first object and the second object. Further, a vector force field is provided that for each point on the deformable curve or surface defines a direction from the point approximately towards the second boundary between the second and the third object, and this vector force field is applied for iteratively deforming the deformable curve or surface convergently towards the second boundary.

Abstract: There is described a method for making a vehicle (2), including a body comprising carbon fibres, preferably a military vehicle. The method consists of the body being wound up over a mandrel with threads (28) wetted in glue. The threads (28) contain carbon fibres. The threads (28) wound around the mandrel (22) are subsequently cured. After the curing, the body is drawn off the mandrel (22), and the ends of the body are cut off at appropriate angles. Then the front end and rear end of the body are closed with closure elements, preferably closure elements containing carbon fibres and armouring materials. During the winding process, one or more layers of lightweight ceramic and/or other armouring materials (26) are laid in, which thereby become integrated in the basic body.

Abstract: A conveyor chain link has a leading edge, a trailing edge, two opposed side edges, a load carrying upper surface and a bottom face. The leading and trailing edges have pluralities of eye parts separated by openings, such that the trailing edge of one belt link may be arranged in the openings arranged on the leading edge of an adjacent belt link. The belt links are connected either by inserting a traverse rod through apertures in the eye parts or by fitting lateral notches in slots provided in sides of the eye parts on the opposite edge on the sides of the eye parts along one edge. Between the leading and trailing edges and the side edges at least a part of a load carrying surface has a one-sided inclination towards one side edge.

Abstract: A new conical roof building method provides flat plates having straight abutting edges and curved outer edges. The plates are placed horizontally edge to edge except for a sectoral opening. The plates are welded together to form a flat disc-shaped blank, leaving an open sector of the blank. Radial supports are welded to a top of the disc-shaped blank. A center of the disc-shaped blank is lifted, forming a conical-shaped structure, closing and abutting edges of the open sector and touching edges of the formerly open sector are welded together, completing the forming of the conical roof.

The electrical connectors and network can form part of the reflective optics and heat removal system. The electrical interconnection system can also form a reliable network that is self-correcting and tolerant of point failures.

Abstract: A solar PV panel has an array of primary mirrors that collects and reflects solar radiation toward an array of dichroic secondary elements. The dichroic secondary elements reflect near-visible solar radiation to an array of near-visible radiation sensitive solar cells and simultaneously transmit infrared radiation to an array of infrared sensitive solar cells. The array of near-visible radiation sensitive cells and the array of infrared sensitive cells are wired in series. The optical properties of the dichoic secondary element, near-visible radiation sensitive cell, and IR sensitive cell are chosen for simultaneous maximum power production from the panel.
