  • Patent number: 6661524
    Abstract: A method and apparatus for measuring ground height in front of a vehicle, such as a vehicle for clearing buried land mines, in which a scanning pulsed laser to used to scan along one or more lines in front of the vehicle, with such scanning being executed more slowly in certain regions where data is collected and more quickly in intermediate regions where data is not collected. The time of flight along those lines is measured, and using that measurement, the ground height calculated and stored, with the higher elevations being discarded as the representing the tops of vegetation and the lower elevations being representative of the ground height or elevation in front of blade. A dozer blade on the vehicle is then adjusted in response to the calculated height to position the blade for the proper depth of cut in order to effectively uncover and remove the buried mines.

  • Patent number: 6345563
    Abstract: An improved reactive armor system having one or more layers of matrix plates, each plate having a plurality of shallow wells with a plurality of blind holes in each well and an explosive pill in each blind hole. An explosive sheet covers each well and is in close proximity to the pills in the associated wells to insure that all the pills within a well will detonate when one pill therein is detonated. A separation plate covering and held in engagement with each matrix plate isolates each well from the other wells.

  • Patent number: 6170355
    Abstract: The invention provides an easily adjustable foot-operated pedal assembly, such as a brake pedal for use in heavy equipment, that can be placed in multiple positions to accommodate people of differing heights and body shapes. The pedal is mounted in an assembly including a dual linkage operating apparatus having one element of that linkage that freely rotates about a shaft. A second link of the pedal linkage is connected to a fixed link through an adjustment mechanism. The fixed link is fixedly mounted to the same shaft as the pedal link. The adjustment mechanism incorporates a latch that has multiple settings yielding three or more pedal positions. The pedal is urged upwardly to effect adjustment to raise the pedal. A latch bar of the pedal assembly is urged up to allow lowering of the pedal.

  • Patent number: 6142055
    Abstract: The invention provides a method and apparatus for firing a guided projectile. The invention provides a matrix of one time shot gun systems. Each one time shot gun system has a one time shot barrel, a one time shot recoil system, a propelling charge, breakable seal, and a guided projectile which is stored in and from the barrel. The one time shot system provides an inexpensive firing system, which eliminates single points of failure that exist in conventional gun systems.

  • Patent number: 6066291
    Abstract: Castings based on the nickel aluminide intermetallic alloy IC-221M were melted and poured with an addition of enough molybdenum to bring its concentration to 5 weight %. This resulted in a minimization or elimination of the nickel-zirconium eutectic phase in the dies machined and prepared from these castings. The benefit of eliminating or minimizing the nickel zirconium eutectic phase with the addition of measurable amounts of molybdenum (Mo) to the nickel aluminide (Ni.sub.3 Al) alloy is the increase in the useful service life of the tooling made from it; thus providing the advantages of increased productivity, enhanced quality and reduced costs in a manufacturing setting. Heat treatment of the dies machined and prepared from these castings was also undertaken. The heat treatment regimen includes solution treatment at 2100.degree. F. for 24 hours and aging from between 1150.degree. F. and 1300.degree. F. for between 12 to 24 hours.

  • Patent number: 5912610
    Abstract: A high energy inductor and method of manufacture relates to an inductor which is capable of mechanically withstanding the high magnetic forces imposed thereon during transfer of high energy pulses. The inductor is wound with a conductor under tensile stress, wherein the conductor has a fixed inner end and a free outer end. The stress is maintained in the finished inductor by means of a clamp attached to and fixing the free end of the conductor. The fabrication method involves inducing tensile stress in the conductor as it is wound on an inductor core and then maintaining the conductor tensile stress in the finished inductor component.
