  • Apparatus and methods for detection of a shot firing event
    Patent number: 11719511
    Abstract: A method of determining an aim point of a firearm or simulated firearm at a time of firing by continuously pulsing a laser coaxially aligned with a barrel of the firearm or simulated firearm. The aim point is then continuously detected by a camera system observing the target. A shot firing event is detected and the last detected laser pulse location on the target prior to the shot firing event is determined. The aim point of the firearm or simulated firearm at the time of firing is extrapolated from the last detected laser pulse location and at least one laser pulse location prior to the last laser pulse location.
    Type: Grant

    Date of Patent: August 8, 2023
    Assignee: InVeris Training Solutions, Inc.
    Inventors: Dave Barrett, Wen Li, Carter Crittenden Bennett, Scott Billington, Steven Fred Hering

  • Model predictive controller solution analysis process
    Patent number: 7949417
    Abstract: The solution from a multivariable predictive controller (MPC) is analyzed and described by providing quantitative input to operators regarding the effect of changing controller limits on the MPC controller solution. This information allows a rapid operator response to changes and more optimal process operation.
