  • Systems and methods for eye tracking calibration, eye vergence gestures for interface control, and visual aids therefor
    Patent number: 10466780
    Abstract: Systems and methods are provided for calibrating eye tracking systems. Eye tracking to objects at known locations allow for the determination of a new calibration. Systems and methods are also provided for controlling human-machine interfaces by gaze gestures based on changes in eye vergence. Visual aids for training to use eye vergence to controls and for other purposes are also provided.
    Type: Grant

    Assignee: Pillantas
    Inventors: Stephen R. Ellis, Matthew D. Moller, Botond Bognar
  • Systems and methods for eye vergence control in real and augmented reality environments
    Patent number: 10401953
    Abstract: Systems and methods are provided that allow a person to exert control in real space as well as in virtual spaces. Eye tracking is employed to determine the direction of the viewer's gaze, and head tracking can be used as needed to track the viewer's head in order to provide a stable virtual environment. Eye vergence can then be used to as a triggering mechanism to initiate responses stored in association with objects in the field of view. Additionally, eye vergence can be used to provide a continuous control.

  • Fluid distribution and contacting elements
    Patent number: 4201736
    Abstract: A packing element for a fluid-fluid, fluid-solid, contacting de-entrainment or reaction apparatus is made from wire using two or more parallel wires which are loosely twisted together, the twisted bundle then being wound into a helix, and the helix then being twisted about a second pair of heavier gauge wires which form a core, so that the individual loops of the helix are spaced helically about the central core, the individual wires being slightly separated from one another to form gaps which can be bridged by a liquid, and encourage capillary flow so as to wet the whole of the packing area.
