Abstract: The disclosure provides rotary machines that include, in one embodiment, a shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first gearbox disposed thereon defining one or more cavities therein. At least one contour is slidably received into an arcuate cavity in an exterior surface of the gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism consisting of gears, crankshafts, bearings and connecting rod creates an oscillatory motion 2 times per revolution such that the contour can navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed. Thus, said working volume can expand and compresses twice per rotatable shaft revolution.

Abstract: Solvent-free, hydrophobically modified urethane (HEURs) compositions produced by reactive extrusion, methods of producing the same, and coating compositions containing the same are described. Such HEURs can be used as solvent-free or low-solvent rheology modifiers in coatings formulations. The HEURs compositions herein are formed by reactive extrusion of a polyether polyol and an isocyanate functional material in the presence of a metal catalyst, and an hydrophobic, end-capping modifier without the need for organic solvents, co-solvents, and/or surfactants. In certain aspects, compositions and methods herein do not require the costly stripping of organic solvent to provide useable product, allow for a 100% active solids HEUR that can be added directly to the grind stage of making a paint composition, and are free of VOC-contributing solvents or co-solvent.

Abstract: A mechanical apparatus for human balance training includes a cross bar whose center is attached to a pivotable protrusion extending from a leg having a base. The apparatus also includes a slidable sheath surrounding a portion of the leg proximate to the pivotable protrusion. The slidable sheath has a plurality of allowed positions relative to the leg, each position limiting tilt of the cross bar to a respective angular range. In some embodiments, each allowed position limits tilt of the cross bar by controlling an extent by which the pivotable protrusion extends out from the sheath. In some embodiments, the sheath is threaded relative to the leg and the allowed positions are a continuous range adjusted by twisting the sheath relative to the leg. In some embodiments, the allowed positions are predefined locking positions. Each locking position limits tilt of the cross bar to a respective predefined angular range.

Abstract: Aspects of the present disclosure enable humanly-specified relationships to contribute to a mapping that enables compression of the output structure of a machine-learned model. An exponential model such as a maximum entropy model can leverage a machine-learned embedding and the mapping to produce a classification output. In such fashion, the feature discovery capabilities of machine-learned models (e.g., deep networks) can be synergistically combined with relationships developed based on human understanding of the structural nature of the problem to be solved, thereby enabling compression of model output structures without significant loss of accuracy. These compressed models provide improved applicability to “on device” or other resource-constrained scenarios.

Abstract: Embodiments described herein are directed to intelligently classifying Web trackers in a privacy preserving manner and mitigating the effects of such Web trackers. As users browse the Web and encounter various Web sites, tracker-related metrics are determined. The metrics are obfuscated to protect the privacy of the user. The obfuscated metrics are provided as inputs to a machine learning model, which is configured to output a classification for the Web trackers associated with the Web sites visited by the user. Depending on the classification, the effects of the Web trackers are mitigated by placing restrictions on the Web trackers. The restrictions for a particular Web tracker may be relaxed based on a level of user engagement a user has with respect to the tracker's associated Web site. By doing so, the compatibility risks associated with tracking prevention are mitigated for Web sites that are relatively important to the user.

Abstract: An apparatus for video coding is provided. The apparatus includes processing circuitry that buffers first boundary pixel values of first reconstructed samples at a first node along a loop filter chain. The first node is associated with a non linear mapping based filter that is applied in the loop filter chain before a loop restoration filter. The first boundary pixel values are values of pixels at a frame boundary. The processing circuitry applies the loop restoration filter on to-be filtered reconstructed samples based on the buffered first boundary pixel values.

Abstract: A flexible, elongated catheter tube having distal and proximal ends and a laser cut section there between. The laser cut section makes up a majority of the catheter length and is cut in a continuous helical pattern forming interlocking teeth which can be sinusoidal, triangular, square or like shapes, preferably sinusoidal. The interior of the tube has a polymeric layer which forms the internal lumen of the catheter. The exterior of the tube has a polymer coating. A short portion of the distal end is uncut and is followed by a narrower terminal section which can be tapered for better blockage penetration. The interlocking teeth disengage and reengage in a fish-scale manner without undergoing plastic deformation of the metal tube and without substantial polymer separation from the tube exterior.
