  • Patent number: 10825230
    Abstract: A hardware-based traversal coprocessor provides acceleration of tree traversal operations searching for intersections between primitives represented in a tree data structure and a ray. The primitives may include triangles used in generating a virtual scene. The hardware-based traversal coprocessor is configured to properly handle numerically challenging computations at or near edges and/or vertices of primitives and/or ensure that a single intersection is reported when a ray intersects a surface formed by primitives at or near edges and/or vertices of the primitives.

  • Patent number: 10696904
    Abstract: The present invention relates to a pyrolysis apparatus comprising a pyrolysis chamber have a first end and a second end, a feed inlet connected adjacent the first end of the pyrolysis chamber, a biochar outlet connected adjacent the second end of the pyrolysis chamber, and a gas outlet in fluid communication with the pyrolysis chamber. The pyrolysis chamber and feed inlet further comprise centreless screw conveyors. The present invention alleviates the problems associated with dust, oils and tars being present in the generated syngas. The present invention can also be used in a method of continuously processing biomass.

  • Publication number: 20200090913
    Abstract: A magnet assembly is disclosed for steering ions used in the formation of a material layer upon a substrate during a pulsed DC physical vapour deposition process. Apparatus and methods are also disclosed incorporating the assembly for controlling thickness variation in a material layer formed via pulsed DC physical vapour deposition. The magnet assembly comprises a magnetic field generating arrangement for generating a magnetic field proximate the substrate and means for rotating the ion steering magnetic field generating arrangement about an axis of rotation, relative to the substrate. The magnetic field generating arrangement comprises a plurality of magnets configured to an array which extends around the axis of rotation, wherein the array of magnets are configured to generate a varying magnetic field strength along a radial direction relative to the axis of rotation.

  • Patent number: 10539727
    Abstract: A method of making a multi-layered film includes depositing thin film layers onto a first side of a double-sided transparent substrate. The thin film layers are transparent, and two adjacent layers of said plurality of thin film layers have different refractive indices. One or more absorbers are deposited at an interface formed between two of the thin film layers that are adjacent to one another, or formed by the first side of the substrate and one of the thin film layers. The absorbers absorb selected wavelengths of incident light and reflect part of the incident light after inducing a phase shift. The location of the interface is selected to provide desired wavelengths of absorbed and reflected light. The multi-layered film has a first appearance when viewed from the first side of the substrate and a second appearance when viewed from the second side of the substrate.

  • Patent number: 10245486
    Abstract: A golf bag having a shoulder strap assembly including a two strap system that can be converted to a single strap system is provided. In the two strap system, Strap A is fitted over one shoulder and Strap B is fitted over the other shoulder. To convert from a double strap configuration to a single strap configuration, Strap A is detached and slipped over the head area and coupled to Strap B. This results in a single strap comprising both Straps A and B. The combined Straps A and B are joined together by a suitable fastening means. For example, complementary male and female members that interlock with each other on the straps can be used. The shoulder strap assembly is durable, lightweight, easy to use, and comfortable. In another embodiment, a central hub connector having four open slots for retaining the shoulder straps is provided. The Straps A and B criss-cross each other in the hub connector. Strap A or B can be removed from the hub connector to convert the two-strap assembly to a single strap assembly.

  • Publication number: 20180214752
    Abstract: An elongated golf bag has a top, a bottom, and four sides surrounding a longitudinal axis. The front side has a front pocket extending forward therefrom. Right and left pockets extend from the right and left side, respectively, both further extending forward of the front side. The pockets include zipper tracks which allow the pockets to be opened forward of the longitudinal axis. A hard base cover surrounds the bottom which, when placed on a level surface, holds the bottom in a position elevated from the surface.

  • Patent number: 9851310
    Abstract: A three-dimensional porous photonic structure, whose internal pore surfaces can be provided with desired surface properties in a spatially selective manner with arbitrary patterns, and methods for making the same are described. When exposed to a fluid (e.g., via immersion or wicking), the fluid can selectively penetrate the regions of the structure with compatible surface properties. Broad applications, for example in security, encryption and document authentication, as well as in areas such as simple microfluidics and diagnostics, are anticipated.
