Abstract: The present disclosure relates to a computer-implemented method, devices and systems for determining a location associated with a gemstone. That method includes training a data model to detect a characteristic associated with a feature of interest pertaining to a gemstones surface. The training including the steps of providing a plurality of training images of gemstones, each training image associated with a label for a feature of interest pertaining to a given region of a gemstone type and an output indicating the specific gemstone type for the label.

Abstract: A method for forming a conductive track on a surface (21) of a substrate (11) that includes providing the substrate (11), wherein the substrate (11) comprises deposited material (23) along a path on a surface (21) of the substrate (11). Generating a laser beam having an optical axis and an energy distribution within a cross-sectional area of the laser beam incident on the surface (21). The energy distribution of the laser beam is non-circularly symmetric about the optical axis at the surface (21). The method further includes directing the laser beam to move along the path to irradiate the deposited material (23) to provide a conductive track along the path. A selected orientation of the energy distribution within the cross-sectional area is aligned with the direction of movement of the laser beam.

Abstract: An apparatus for and a method of forming a plurality of groups of laser beams (2, 2?, 2?) are defined. Each group (2, 2?, 2?) may comprise two or more laser beams. The apparatus comprises a first diffractive optical element (3, referred as DOE) and a second diffractive optical element (8), the first DOE (3) being arranged to receive a first laser beam (1) and to divide this into a plurality of second laser sub-beams and the second DOE (8) being arranged to receive said plurality of second laser sub-beams and to divide each of these into two or more groups of third laser sub-beams (2, 2?, 2?), the separation of the groups in a direction perpendicular to a first axis being adjustable by rotation of the first DOE (3) about its optical axis and the separation of the third laser sub-beams (2, 2?, 2?) within each group in a direction perpendicular to the first axis being adjustable by rotation of the second DOE (8) about its optical axis.

Abstract: A docking station (10) for an elongate rectangular mobile device. A first adjustable slide clamp member (14) is fitted in aperture (28) and is capable of adjustment in one direction. A second adjustable rotate clamp member (16) has a plug (85) for interconnection with a socket of the mobile device. The slide clamp member (14) has a clamp surface (32) and comprises a ratchet arm (26). The rotate clamp member also has a clamp surface (32c) and is rotatably disposed with respect to the body so that it can rotate between two positions. In a first position the clamp surface is perpendicular to the direction of movement of the slide clamp (14). In a second position it is parallel to that direction. In the second position, it opens a second aperture opposite the rotate clamp member and in which the slide clamp member can be inserted.

Abstract: A portable electronic device includes a hinge assembly comprising an axle, the hinge assembly coupling a first mating end of a first housing to a second mating end of a second housing, the second housing being movable relative to the first housing from an open position in which the axle is in a first position near to the first mating end and the second mating end and a folded position in which the axle is in a second position spaced from the first mating end and the second mating end such that the first mating end and the second mating end are movable toward one another to move the portable electronic device to a partially open position for clipping to an object; and a processor in electrical communication with electrical components in one of the first housing and the second housing.

Abstract: A mobile device includes a first housing, a second housing, and a hinge assembly rotatably coupling the first housing to the second housing and enabling movement of the device between an open configuration and a closed configuration. When the device is in the open configuration, the first housing is planar with the second housing.

Abstract: A process and apparatus are described for converting a feed that is substantially comprised of halogenated materials, and especially byproduct and waste chlorinated hydrocarbons as are produced from a variety of chemical manufacturing processes, to one or more higher value products via a partial oxidation reforming reaction step. These products can be in the form of a useful or salable acid product and/or a product synthesis gas comprised of carbon monoxide and hydrogen, or the reaction product including the same hydrogen halide, carbon monoxide and hydrogen components can be employed as a feed in the synthesis of a different useful or salable product.

Abstract: An organic additive is removed from a ceramic honeycomb by an improved method by contacting each end of the extruded honeycomb with a member that has a gas permeability no greater than the outer wall, the member essentially covering the ends and heating the honeycomb to a temperature sufficient to remove the organic additive.

Abstract: A pyrolysis oven provides uniform pyrolytic coatings on capacitor anodes. An oven chamber contains cross-flow blowers situated to provide uniform laminar flow of oven atmosphere over the objects to be treated. The top and side walls of the chamber meet in an inverted V such that when the blower operate, a vortex is created in the inverted V in the chamber.

Abstract: The preparation of vinyl halide monomer, and further to polyvinyl halide, starting from C1 compounds, involving conversion of methane or methanol to methyl halide; condensation of methyl halide to ethylene and co-product hydrogen halide; oxidative halogenation of ethylene to vinyl halide monomer; separation of vinyl halide monomer from any methyl halide present in the vinyl halide monomer stream; optional recycling of the methyl halide recovered to the condensation step; and recovery and optional recycling of the co-product hydrogen halide. Optionally, the vinyl halide monomer may be polymerized to polyvinyl halide to facilitate separation of the monomer from methyl halide. Methyl halide may be obtained via oxidative halogenation of methane in the presence of a rare earth halide or rare earth oxyhalide catalyst. Optionally, the methyl halide may be converted to methanol.
