Patent number: 11301601Abstract: A domain specific language, or Scenario Description Language (SDL), can be used for quickly enumerating scenarios in a simulation for testing and validating interaction of an object (e.g., an autonomous vehicle) within an environment. Scenarios in a simulation are defined using one or more primitives. Primitives are used to define objects to be instantiated (such as body size, position, orientation, velocities, etc.) and/or actions to be performed by the objects in the simulation (such as wait for a period of time, goal positions, follow a particular object, etc.). The SDL enables simple creation of multiple scenarios by combining primitives combinatorially and in some examples, limiting which scenarios are created to those that correspond to combinations that provide meaningful information. Additionally, the SDL allows for instantiation to be agnostic of map features so that a particular scenario can be instantiated automatically over all possible positions within a map.Type: GrantFiled: October 18, 2019Date of Patent: April 12, 2022Assignee: Zoox, Inc.Inventors: Ryan Martin Cahoon, Gary Linscott, Adrien Treuille

Patent number: 11288424Abstract: A method for accelerating an explicit finite element analysis (FEA) simulation of a modeled system or process includes performing an initial iteration of the FEA simulation according to a baseline time interval via an FEA computing network, and calculating a criteria ratio of a predetermined set of scaling criteria for the modeled system or process. The method includes determining a time-scaling factor using the criteria ratio via the FEA computing network as a function of the criteria ratio, and then applying the time-scaling factor to the baseline time interval to generate a scaled time interval. The scaled time interval accelerates simulation time of the FEA simulation. The method includes performing a subsequent iteration of the explicit FEA simulation at the scaled time interval using the FEA computing network. The process continues for subsequent iterations, with the time-scaling factor adapting with each iteration.Type: GrantFiled: June 25, 2019Date of Patent: March 29, 2022Assignees: GM Global Technology Operations LLC, UT-Battelle, LLCInventors: Jian Chen, Hui Huang, Zhili Feng, Blair Carlson, Hui-Ping Wang, Wayne Cai

Patent number: 11151013Abstract: The present disclosure provides systems and methods for performance evaluation of Input/Output (I/O) intensive enterprise applications. Representative workloads may be generated for enterprise applications using synthetic benchmarks that can be used across multiple platforms with different storage systems. I/O traces are captured for an application of interest at low concurrencies and features that affect performance significantly are extracted, fed to a synthetic benchmark and replayed on a target system thereby accurately creating the same behavior of the application. Statistical methods are used to extrapolate the extract features to predict performance at higher concurrency level without generating traces at those concurrency levels. The method does not require deploying the application or database on the target system since performance of system is dependent on access patterns instead of actual data.Type: GrantFiled: January 29, 2018Date of Patent: October 19, 2021Assignee: Tate Consultancy Services LimitedInventors: Dheeraj Chahal, Manoj Karunakaran Nambiar

Patent number: 11126759Abstract: The disclosed methods and systems allow adding constraints (“mates”) between components of the CAD model when in a graphics mode (i.e., when bodies of the CAD model are not loaded). Information regarding CAD model entities is accessed from a computer database, where the CAD model entities belong to one or more components of the subject CAD model. A graphical representation of the subject CAD model is presented to a user without loading bodies of the subject CAD model. The user is enabled to add a constraint between first and second entities of the subject CAD model, and information for the added constraint is stored with the subject CAD model in the computer database. Displaying the model in graphics mode saves time as well as memory usage, and the added constraints persistent after resolving the components from the graphics mode.Type: GrantFiled: November 13, 2017Date of Patent: September 21, 2021Assignee: Dassault Systemes SolidWorks CorporationInventors: Sushant Sinha, Nick Birkett-Smith, Christopher George Brooking
