Abstract: When using finite-state methods to capture multimodal integration, it is desirable to abstract over certain aspects of the gestural content. For abstraction, the gestural input is represented as a transducer which relates the specific content of the gestures to the gesture symbols. After multimodal integration, a projection is taken of the resulting finite-state machine and it is composed with the transducer representing the gestural input in order to reincorporate the specific contents that were left out of the finite-state process.

Title: Two-planar vena cava filter with self-centering capabilities
Inventor: SUON NAROUN
IPC: A61F2/01
Filed: 2001-05-29
Granted: 2009-06-16
Abstract: A self-centering filter is useful for trapping blood clots, reducing their size and arresting their further migration from the vena cava into pulmonary circulation. The two-planar filter design is formed from a conical array of filter wires wherein two sets of filter wires are included, each set differi ng in length from the other. The filter wires diverge from a common apex at one end and extend radially outwardly therefrom to an attachement end attachable to the wall of a blood vessel such that the attachement ends of the first se t of wires are anchored at a location spaced apart from the location of anchoring of the attachement ends of the second set, effecting a two-planar filter design. This establishes a single filtering element having two planes of contact with the vein wall which also provides for centering of the filtering element. At least one of the sets of wires contains barbs, e.g. hooks, for anchoring the filter to the inner venal wall.

Abstract: A flake-based pigment is provided having improved specular reflectance characteristics in the visible wavelength range. The flake-based pigment has a plurality of composite reflective flakes each formed of a support layer on one or both opposing sides of the support layer. This flake structure exhibits a uniaxial compressive strength much greater than a corresponding uniaxial tensile strength. The structure of the flakes provides the benefits of rigidity and brittle fracture during manufacture and application processes, which ultimately provides favorable planar and specular reflectance characteristics to the pigment in the visible wavelength range. A variety of outer coating layers can be formed around the composite reflective flakes, such as various dielectric and/or absorber layers, to produce desired optical characteristics in the pigment. In addition is claimed, a method of fabricating the reflective flake-based pigment and a colorant composition comprising a polymeric medium and a plurity of the composite reflective flakes.

Abstract: The invention relates to pressure-sensitive adhesive layers produced from aqueous dispersions consisting of polymers with isocyanate-reactive groups and of surface-deactivated solid isocyanates whose shear strength can be improved by elevated temperatures. In a first step, a property profile results after water is removed by drying at drying temperatures (a) ranging from 20 ~C to 95 ~C. Said property profile can be influenced in a second step, by a thermal treatment (b) on the single or double-sided pressure-sensitive adhesive tape or transfer tape or on the finished bonding, in order to improve shear strength (or rather to render it less inclined to creeping) with an acceptable loss of surface adhesiveness. The duration of the thermal treatment (b) ranges from a minimum of 5 seconds at 135 ~C (or higher temperatures) to a maximum of 30 minutes at 90 ~C (measured in the layer). The maximum temperature of the thermal treatment (b) exceeds the drying temperature (a) by at least 40 ~C.  The cross-linked pressure-sensitive adhesive layers are used in high-performance adhesives, which are creep-resistant at high temperatures, in adhered joints in assembling and manufacturing processes, in adhesive tape configurations used in the field of fastenings, which can be statically subjected to stresses. They can also be used for fastening bondings with increased temperature stability and shear strength.

Abstract: In a downhole centrifugal pump, diffusers are stacked one on top of each other inside of tubular pump housing without contacting the pump drive shaft or impellers. A first compressive device applies a pre-compressive force to a stack of diffusers to prevent the diffusers from rotating inside the tubular housing of the pump with the drive shaft. A second compressive device located between the first compressive device and the stack of diffusers applies another compressive load on the stack of diffusers in the event the first compressive device ceases to apply the compressive load.

The concentration of ions is sensed by measurement of the current flow while maintaining a chosen voltage. The inhibitor solultion (8) may be used in conjunction with an electroosmotic current to drive ions into the concrete a nd towards the steel; this may be done prior to applying the cathodic impressed current, or concurrently therewith by providing secondary electrodes (6, 7). Program controller means in the power station switches from one mode of delivery to another when current usage, measured by current density, is deem d to have become uneconomical.

Abstract: Barley with reduced SSII activity has a starch structure with reduced amylopectin content and a consequent high relative amylose content. Additionally the grain has can have a relatively high .beta. glucan content. The structure of the starch may also be altered in a number of ways which can be characterised by having a low gelatinsation temperature but with reduced swelling.  The viscosity of gelatinised starch of the starch is also reduced. There is a chain length distribution of the amylopectin content and a low crystallinity of the starch. The starch is also characterised by having high levels of lipid associated starch exhibiting very high levels of V form starch crystallinity. The dietary fibre content of the starch is high. This has desirable dietary and food processing characteristics.
