Abstract: A method is provided for producing a vortex ring in a liquid medium. The method includes concatenating pairs of insulated anode and cathode rings into a stack; inserting the stack into a vertically oriented chamber; disposing a cylindrical cavity below the chamber; inserting a piston into the cavity; connecting the chamber to the medium; and raising the piston to displace the medium while the stack produces an annular bubble that induces the vortex ring. In particular, the medium is water and the stack separates the medium into hydrogen and oxygen gas.

Abstract: A sensor system is provided for monitoring anti-personnel effectiveness of a gun that fires a projectile against a mannequin target. The system includes an instrumentation sensor, an aggregation controller and a base station. The instrumentation sensor is disposed on the target. The sensor transmits a status condition based on electrical integrity. The status condition is either intact as default or else disablement in response to impact from the projectile. The aggregation controller receives the status condition from the sensor and transmits the status information as aggregated information. The base station receives the aggregated information for analysis to determine the effectiveness in response to the gun firing at the target.

Abstract: A method is provided for aligning a gun barrel. The method includes disposing a signal transmitter at the barrel's muzzle, distributing sensors around the barrel to receive the muzzle's signal, calculating the muzzle's coordinate position based on the signal, aiming an electro-optical sensor at a target to determine a miss distance, and calibrating the gun barrel based on the electro-optical sensor based on the miss distance.

Abstract: A visual automated score system (VASS) is provided to enable computerized accuracy assessment of weapons systems through video photography. Images are fed into a computer which tracks the intended target, detects impact points and then provides human operators with an automatically computed miss distance based on the cross-correlation of at least two video images. The VASS may then provide feedback to the weapons system to correct and direct gunfire.
