Title: Mixed reality system with reduced power rendering
Inventor: LI XINTIAN
IPC: G09G3/00
Filed: 2017-11-15
Abstract: Disclosed is a method for presenting mixed reality content using a mixed reality device. The method comprises obtaining sensor data associated with a physical environment, wherein the sensor data is obtained using one or more sensors. The method also comprises determining, by a visual processing unit (VPU) of the mixed reality device, a pose of the mixed reality device using the sensor data, sending the pose of the mixed reality device from the VPU to at least one graphics processing unit (GPU) and identifying, by the at least one GPU, mixed reality content corresponding to the pose of the mixed reality device. The method also comprises determining that the identified mixed reality content is dynamic content and sending a message from the at least one GPU to a central processing unit (CPU) operating in a low-power mode, wherein the message causes the CPU to transition from the low-power mode to a high-power mode. The method also comprises sending the pose from the VPU to the CPU, receiving, at the at least one GPU, the dynamic content from the CPU, aligning, by the at least one GPU, the dynamic content to the physical environment, sending the aligned dynamic content from the at least one GPU to the mixed reality device, and presenting the aligned dynamic content using a display of the mixed reality device.

Title: Thick, long seam welding system and method for distortion control and non post weld heat treatment of pipeline hot tap fittings
Inventor: VROLYK CHRIS
IPC: B23K31/00
Filed: 2018-03-30
Abstract: A method for limiting fitting distortion when welding a fitting (10) to an in-service pipeline- where the fitting (10) includes a thick, longitudinally extending, seam located between fitting halves- involves welding, on each side of the fitting, a middle third section (31) of the seam in a pyramid-like fashion using an inward progression starting from an end of the middle third section (31) along a profile of a seam bevel (19), and welding outer third sections (37) of the seam (20) using an outward progression from an end adjacent to the middle third section (31) along a profile of the seam bevel (19). The welding of each of the three sections per side includes a temper bead welding technique of at least two layers to provide stress relief in lieu of traditional post weld heat treatment.

Title: Method for improving efficiency of an ammonia synthesis gas plant
Inventor: HAN PAT A
IPC: C01B3/02
Filed: 2018-07-11
Abstract: Method for improving efficiency of an existing ammonia synthesis gas plant or a new ammonia synthesis gas plant by establishing a combination of secondary steam reforming using oxygen from electrolysis of water for the production of ammonia synthesis gas. The method comprises the steps of a) establishing an electrolysis unit and preparing a separate hydrogen gas containing stream and a separate oxygen gas containing stream by electrolysis of water; (b) establishing a gas pipe for transporting the separate hydrogen gas containing stream from the electrolysis unit to the synthesis gas compressor and/or to the methanation step; and (c) establishing a gas pipe for transporting at least part of the separate oxygen gas stream from the electrolysis unit to a burner in the secondary reformer. The disadvantage of existing method involve a relatively high hydrocarbon feed stock and fuel consumption for use in heating the endothermic primary steam reforming in the fired primary steam reformer and consequently a large CO2 emission in the flue gas from burners used to heat the reformer. The method allows for lower fuel consumption and a significantly longer equipment lifespan.

Abstract: FIELD: nuclear fuel products' disposal. SUBSTANCE: invention relates to gas fluoride processing of exhausted nuclear fuel and can be used to deactivate and isolate useful components from large variety of materials, in particular, to process fuel-containing mass from ruins of fourth block of Chernobyl nuclear station. Aim of invention is increasing productivity and isolation degree of desired component in the process of layer-by-layer jet fluoridation of initial material with elementary fluorine in open-space condition and at local temperatures of reaction surface providing complete gasifying of formed fluorides, which are removed from reaction zone with aid of pressure and/or aspirating pneumotransportation means. To do this, high-temperature, diffusion and fluoro-radical fluoridation condition is initiated by agency of flammable-in-fluorine substances preliminarily applied onto reaction surface. Thermal breakdown of some higher fluorides is combated by shifting equilibrium in zone with predetermined temperature gradient and additionally enriched with fluorine with subsequently passing fluoride gas-suspension through quenching zone thereby transferring the system into stationary existence region. EFFECT: increased productivity.

Abstract: This invention provides a method for making a multi-color woven, foamed skid-proof pad and products made by the same. The mutli-color woven, foamed skid-proof pad comprises cotton threads as basic materials. Colored and environment-safe plastic particles are then heat molten, pressed and mixed or coated to join the cotton threads such that the plastic particles are able to attach around the thread surfaces to obtain cotton threads having a colorful coating. The threads are then interwoven to form a mesh structure. A skid-proof pad featuring skid-proof effects and providing aesthetic appearance may be obtained after foaming. The product may serve as pads used in Yoga, exercises or general households. The interwoven products may also be applied in purses and handbags or bag structures without applying the foaming process, so as to allow a variety of applications that are different from the conventional skid-proof pads.
