  • Patent number: 11886445
    Abstract: An example method of performing searches by comparing regions includes identifying a search point contained in geo-located data. The search point is nearest in distance to a query location. A search region associated with the search point is determined. The search region includes neighbor points contained in the geo-located data that are nearest the search point. Centroids corresponding respectively to the plurality of neighbor points of the search region are determined. The centroids of the search region are compared to other centroids corresponding to other regions of the geo-located data. The number of other centroids that match with the plurality of centroids are counted, and the counts are placed in descending order, to list the other regions having the highest similarity first. An ordered list of the other regions is generated based on their respective similarities to the query region.

  • Patent number: 11821705
    Abstract: A small lightweight weapon system for integration into an unmanned aerial vehicle comprises a weapon operating group which utilizes blowback operation to fire a full-powered centerfire rifle ammunition. An operating rod of the weapon operating group has an axis of translation offset from the longitudinal axis of the barrel thereby creating a moment couple on the system. A motor assembly controls the operation of the weapon operating group. Through a gear train, actuation of the motor assembly lifts a sear against a return torsion spring, which holds the operating group back when not firing. The gear train comprises a one way flywheel disconnect to increase the torque of the direct current motor and overcome the force of the torsion spring. Intelligent motor commutation and burst control are achieved through an encoder and software package.

  • Patent number: 11780141
    Abstract: The present invention is directed to a continuous process for producing a foamable celluloid product by introducing a solid component (comprising nitrocellulose, chemical blowing agent (CBA), stabilizer and alcohol) and a liquid component (comprising camphor and acetone) into a mixer/devolatilizer machine where the chamber is under atmospheric pressure and having significant overhead space. The chamber is comprised of two zones wherein the first zone has a temperature that is less than the second zone and at least one rotor comprising hollow, temperature-controlled arms having a tilted angle affixed to the rotors. The rotors of the mixer/devolatilizer machine act to mix the solid and liquid components under lower shearing forces, lower mechanical stress and longer residence times than those used by twin-screw extruders.
