 | The MTI-2100 is a measurement system that provides for non contact precise measurement of the position, the displacement (micro-positioning), and the vibration of an object in planar motion. By using fiber optic technology, these measurements provide assistance to thoroughly understanding the structural dynamics of a planar actuating object. This report describes the operational principles of the MTI-2100 Fotonic(TM) Sensor measurement system. To illustrate how it works in practice the measurement ... |

| As low intensity conflicts become more prevalent worldwide, nonlethal solutions are often appropriate responses to such circumstances and can help to prevent escalation of the event to a lethal level. The ability to disperse angry crowds often hinges on calming or isolating a few individuals. The following report details the general performance of selected paintball brands with regard to range and accuracy. In addition, simple methods of increasing the performance ... |

| Gun barrel straightness is a critical manufacturing requirement for all calibers. Precision laser-based photo diode systems have been developed and perfected for quick and accurate centerline straightness measurement of large caliber smooth bore barrels. However, an equivalent system for medium caliber does not exist. A reduced caliber not only means smaller mechanical and electrical components, but also that barrel rifling will be present. This presents an added challenge to the ... |

| A new solventless bore cleaning technique, marketed by GI Industries, is currently under review by the U.S. Army Research Laboratory, Benet Laboratory, and the Aberdeen Test Center. Previous studies have shown that this new cleaning system is efficient at removing propellant residue/glaze without producing any measurable bore wear. This report speaks to both the subtle question of whether or not this new method of cleaning roughens the surface finish; but ... |

| Bore cleaning is an essential part of gun barrel maintenance. The technical manual for the Abrams tank gun barrel calls for bore cleaning to occur after every firing exercise. Standard practice at a military proving ground, such as Aberdeen Proving Ground, MD, is to clean the barrel after every firing program, perhaps 5 to 10 cleanings per barrel per year, 250 total cleanings per year. The degree to which a ... |
