  • Method of processing fluoroscopy images
    Patent number: 10813611
    Abstract: A method of extracting mechanical activation of the left ventricle from a sequence of contrasted X-ray fluoroscopy images is provided. The method includes: processing the image sequence to perform segmentation of the coronary veins; annotating branches of the segmented coronary veins; tracking the positions of the annotations throughout the fluoroscopy image sequence; computing the principle components of the motion of the annotations from the tracked positions; projecting the motion of the annotations to the axis corresponding to a first principle component; and analyzing the resulting motion curves to identify a latest activating region of the left ventricle.
    Type: Grant
    Filed: January 28, 2019
    Date of Patent: October 27, 2020
    Inventors: Daniel Toth, Peter Mountney, Tanja Kurzendorfer, Christopher A. Rinaldi, Kawal Rhode

  • Propulsion unit fireable from an enclosure
    Patent number: 5099764
    Abstract: A recoilless propulsion unit fireable from an enclosure utilizes a releasy sealed multi-holed nozzle member to expel a fluid therefrom by a closed-breech type piston that is activated by a propellant charge. The propulsion unit after firing has minimum impact of overpressure, noise on both the launch crew and has no flash or smoke signature emitted therefrom.

  • Apparatus and method for a composite polymer rifling disposable gun tube
    Patent number: 5054224
    Abstract: An apparatus and method for producing a disposable composite laminate gun th polygon rifling and integrally fabricated conically shaped chamber section. A polygonal shaped barrel mandrel is joined with a radial segmented chamber mandrel, wound with alternate helical and hoop filament wraps, impregnated and cured to produce an inexpensive, light weight gun.
