  • Patent number: 11893326
    Abstract: Conventionally, manufacturing of molded parts using composite materials has led to poor dimensional accuracy and tensile strength due to improper curing thus resulting in rejection or early/premature failure of composite part. Embodiments of the present disclosure provide simulation-based systems and methods for manufacturing/generating molded parts using reinforced composite materials. The optimized cure cycle is computed for a given component without carrying out numerous experiments. The present disclosure implements multiscale method and surrogate modeling in virtual testing for more accurate and faster manufacturing of molded parts. Process parameters for specified qualities (e.g., minimum residual stresses, minimum deformation, etc.) required for a part are determined along with least process manufacturing time. The resulting optimized time dependent cure cycle for each thermal zone of the heated mold is transferred to a master controller (e.g.

  • Patent number: 11740612
    Abstract: Conventionally material selection of composite structure is performed by using discrete materials available in manufacturer's databases. Thus, tailorable nature of composite materials is not exploited to achieve superior performance. Further, conventional methods perform material selection and sizing separately and do not take into account the influence of sizing on material selection and vice versa. Embodiments of the present disclosure provide systems and methods for multiscale material selection for designing of mechanical systems that incorporates tailoring of material microstructures and sizing to achieve improved solutions. The microstructure properties are obtained by using analytical and computational models for various composite materials. These models compute structure-property relations between bulk material properties and their micro-structural constituents.

  • Patent number: 11591988
    Abstract: A valve, such as a throttle valve plate, which is suitable for use with a throttle assembly, and is able to withstand a backpressure test. The throttle valve plate includes a flat plate, and a plastic material overmolded onto a portion of the valve plate. The plate includes at least one rib, and may include a plurality of ribs, allowing for a thinner and lighter weight plate which is manufactured at a lower cost. The valve may also be a two-piece valve plate having an overlap portion. The two pieces of the valve plate overlap at the portion of the valve plate which interfaces with the shaft of the throttle assembly. The remaining portion of the plate surface includes at least one ribbed feature, and may include a plurality of ribbed features which reduce material usage and therefore reduce weight and cost, but also provide the required strength and rigidity.

  • Patent number: 10601640
    Abstract: An applied intelligence framework may receive log information descriptive of a cloud computing stack. The applied intelligence framework may generate a stack token. The stack token may include a computer resource node representative a computer resource of the cloud computing stack. The applied intelligence framework may access, from an ontology repository, a diagnosis instruction. The diagnosis instruction may determine a fault based on at least one of the log parameters. The applied intelligence framework may execute the diagnosis instruction to determine the fault. The applied intelligence framework may append, to the stack token, a fault node representative of the fault. The applied intelligence framework may query an ontology repository based on the stack token to identify a resolution identifier. The applied intelligence framework may append, to the stack token, a resolution node.

  • Patent number: 9657650
    Abstract: A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly includes an intermediate gear and a sector gear and transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the sector gear and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the pinion gear causes rotation of the gear assembly, against the bias on the sector gear, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A position sensor assembly determines a position of the plate.

  • Publication number: 20150112643
    Abstract: The invention provides a method of automating the classification of a diamond gemstone. An infra-red absorption spectrum of the gemstone is provided. Features corresponding to absorption by water and intrinsic absorption by a diamond lattice are subtracted from the absorption spectrum. The spectrum is analysed to identify predetermined absorption features corresponding to lattice defects in the diamond. The gemstone is classified according to the intensities of the predetermined absorption features. The results of the classification are saved in a database.
