David Houlton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hardware accelerated simulation of atmospheric scattering
    Patent number: 9836877
    Abstract: A method and system may include a hardware texture unit having logic to receive parameters of a view ray for a pixel of a graphical scene, and determine an illumination of the view ray. The illumination, which could indicate an in-scatter illumination percentage for the view ray, may be passed to a software module such as a pixel shader for rendering of the pixel.
    Type: Grant

  • Agitator with improved blade configuration
    Patent number: 7296925
    Abstract: An agitator, in particular for dispersing gases in liquids, includes a plurality of blades, with each blade being constructed to have a blade portion bent forwards in a rotation direction. The blade has a trailing end region, which defines a blade portion bent forwards in a rotation direction, and a leading end region, which is bent inwards at an angle in a direction toward the blade portion.
