  • Publication number: 20240392964
    Abstract: The invention discloses systems and methods for predicting and controlling lean blowout in combustion systems such as turbines, engines and combustors. The system 100 is configured to detect and predict time of occurrence of blowout using a computer 105 and to take control action by a controller 110 through actuators 103, to prevent the blowout. The method 200 involves acquiring time series data (202) of combustion in the combustion system, including acoustic pressure amplitude, chemiluminescence intensity, or global heat release rate, fitting a log periodic power law equation to the time series data (208), computing a time of impending blowout using the fit equation (210), and controlling the combustion unit (212) to move away from impending blowout and prevent the blowout. The invention provides for predicting exact blowout times significantly earlier, and to control the combustion unit to prevent blowout, thus enabling reduction in emissions.

  • Patent number: 12056854
    Abstract: Embodiments of the present invention provide end-to-end frame time synchronization designed to improve smoothness for displaying images of 3D applications, such as PC gaming applications. Traditionally, an application that renders 3D graphics functions based on the assumption that the average render time will be used as the animation time for a given frame. When this condition is not met, and the render time for a frame does not match the average render time of prior frames, the frames are not captured or displayed at a consistent rate. This invention enables feedback to be provided to the rendering application for adjusting the animation times used to produce new frames, and a post-render queue is used to store completed frames for mitigating stutter and hitches. Flip control is used to sync the display of a rendered frame with the animation time used to generate the frame, thereby producing a smooth, consistent image.

  • Patent number: 10957078
    Abstract: A raster unit is configured to generate different sample patterns for adjacent pixels within a given frame. In addition, the raster unit may adjust the sample patterns between frames. The raster unit includes an index unit that selects a sample pattern table for use with a current frame. For a given pixel, the index unit extracts a sample pattern from the selected sample pattern table. The extracted sample pattern is used to generate coverage information for the pixel. The coverage information for all pixels is then used to generate an image. The resultant image may then be filtered to reduce or remove artifacts induced by the changing of sample locations.
