Abstract: An improved long-range facial recognition system is provided. The facial recognition system includes an integrated, rifle-like mounting platform with modular and interchangeable components, including a machine-vision camera, a facial recognition module, and an aiming scope. The mounting platform includes an elongated frame, a hand grip, a shoulder stock, and an underbody support attachment for an optional bipod. The mounting platform provides an intuitive, shoulder-operated support structure for stabilizing the machine-vision camera and reducing vibrations that otherwise inhibit long distance imaging.

Abstract: A catheter for retroprofusing a venous junction formed by first, second and third veins, includes an elongate tube having a plurality of channels including a through-lumen extending between a proximal end and a distal end. A proximal balloon is inflatable to partially occlude the third vein, while a distal balloon is inflatable to partially occlude the second vein. An operative region of the catheter between the first and second balloons is adapted to pressurize the venous junction with arterial blood to produce retrograde blood flow in the first vein.
