  • Publication number: 20230122396
    Abstract: The present disclosure relates to devices and methods for providing access to graphics or compute hardware acceleration to applications executing in a guest environment. The devices and methods may provide virtualization support to graphics or compute devices so that graphics or compute devices may be projected inside of a guest environment. The devices and methods may share the physical resources for graphics and compute hardware acceleration by coordinating the use of the graphics or compute hardware acceleration across a spectrum of devices, environments, or platforms.

  • Publication number: 20220297664
    Abstract: A method of operating an accessory drive system for a motor vehicle, wherein the accessory drive system includes one or more accessory components, a motor generator of the motor vehicle, and a flexible drive element configured to transmit a torque load between the one or more accessory components and the motor generator, includes determining a maximum permissible flexible drive element torque threshold, detecting an increase in torque demand on the flexible drive element, determining when the torque demand on the flexible drive element will exceed the flexible drive element torque threshold, and reducing the torque demand of one or more of the accessory components so that the flexible drive element torque threshold is not exceeded.

  • Patent number: 11306678
    Abstract: A piston includes an annular body including a crown portion defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, and a circumferential direction. The crown portion includes a top squish surface, and a circumferential annular wall extending downwardly axially from the top squish surface as well as a skirt. A first piston ring receiving groove is spaced away from the top squish surface, an upper land and a lower land extend from the first piston ring receiving groove, and a bottom blend connects the lower land to the first piston ring receiving groove.

  • Publication number: 20220106923
    Abstract: An annular cylinder liner includes an annular body defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, a circumferential direction, a first longitudinal end, a second longitudinal end, and a liner length measured from the first longitudinal end to the second longitudinal end along the longitudinal axis. The annular body also includes a shoulder that is disposed at the first longitudinal end, defining a shoulder axial thickness measured along the longitudinal axis. A ratio of the liner length to the shoulder axial thickness ranges from 24.0 to 46.0.

  • Publication number: 20210154799
    Abstract: An abrasive suspension jet cutting system, the system includes a cutting head. The cutting head has a feed assembly, nozzle and acceleration cavity therebetween. The feed assembly has a slurry orifice and a shielding fluid orifice. Within the acceleration cavity abrasive slurry and shielding fluid are accelerated together from the slurry orifice to the nozzle while maintaining a shielding fluid barrier substantially unmixed with the abrasive slurry around the abrasive slurry. The cutting head is further configured to have both the slurry and shielding fluid pass substantially unmixed through the nozzle thereby limiting nozzle wear. A wear control system is provided to reduce wear of the nozzle and other system components during start and stop. The system may further include a reclamation system that collects and reclaims used abrasive particles and fluid and returns them back to the cutting head to be reused thereby reducing system operational costs.

  • Publication number: 20200257015
    Abstract: A model can be trained for discriminant analysis for substance classification and/or measuring calibration. One method includes interacting at least one sensor with one or more known substances, each sensor element being configured to detect a characteristic of the one or more known substances, generating an sensor response from each sensor element corresponding to each known substance, wherein each known substance corresponds to a known response stored in a database, and training a neural network to provide a discriminant analysis classification model for an unknown substance, the neural network using each sensor response as inputs and one or more substance types as outputs, and the outputs corresponding to the one or more known substances.

  • Patent number: 10704837
    Abstract: The present invention relates to a condenser for condensing gasses. The condenser comprises: an inner tube (1) having a bore (3) therethrough; an outer tube (2) having a bore (8) therethrough and two ends, the inner tube (1) passing through the bore of the outer tube (2); and a seal (15, 16) at each end of the outer tube. The outer tube has exterior and interior fins and is sealed to the inner tube so as to define a sealed space (11) between the inner tube and the outer tube. The space (11) is adapted to contain a liquid in contact with the inner tube (1) and the outer tube (2). The invention further relates to a method of condensing a gas using the condenser, a process of making a chemical using the condenser and a kit adapted to be assembled into the condenser.

  • Publication number: 20190303832
    Abstract: A method and system for benchmarking a trade compliance program against government agency standards comprised of a database of government agency standards cross-referenced to trade compliance program elements and a web-based interface for user access to the trade compliance program elements. The user inputs information regarding the trade compliance program elements present in the user's trade compliance program. The method and system cross-reference the program elements present in the user's trade compliance program with government agency standards on the database and provide a count of government agency standards met by the user's trade compliance program, and provide a count of government agency standards that are not met by the user's trade compliance program.
