Abstract: The measuring device described herein relates to an automatic wood marker attachment device. The device can be selectively attached to a chainsaw or power saw. More specifically, the device is clamped to the handlebar of a chainsaw or power saw using clamping arms. A pair of independently operating and articulating laser sources are used for projecting linear laser beams. The laser beams provide markings on a wood log to enable an operator to make accurate and precise cuts using the automatic laser markers. The laser sources are controlled using a control button to independently operate the laser sources. Further, the laser sources can be adjusted to any desired angle to allow automatic marking at any predeterminable direction and spacing.

Abstract: An amputation system includes a cutting element having a cutting blade traversing a V-shape. The V-shape has a vertex and an angle in a range of 90-120°. A rod, rigidly coupled to the cutting element, has its longitudinal axis aligned with the vertex so it bisects the angle of the V-shape. A barrel having a bore receives at least a portion of the rod therein wherein the rod's outboard end resides in the bore. An energetic energy source, positioned in the bore adjacent to the rod's outboard end, generates a pressure force that is incident on the rod's outboard end. The pressure force is one that peaks within 0.5 milliseconds to propel the rod from the bore at a velocity in a range of 300 to 1000 feet per second.

Abstract: A method for chemically neutralizing a nitroarene explosive uses a nitroarene hypergol having an ?,?-amine and an accelerant that is applied to the explosive composition to cause ignition of the explosive composition. The method may be used to neutralize active mines.
