  • Patent number: 7162943
    Abstract: A method and system for neutralizing mines has a vehicle carrying fluid connected to a pump and cavitation pressure vessel that creates high pressure fluid. An actuator valve modifies the flow characteristics of the high pressure fluid to be pulsating at selectively different frequencies, pressures, and flow rate. Nozzles on the vehicle jet high pressure fluid therethrough and a framework on the vehicle orients the nozzles to direct the jetted flow of high pressure fluid downward and into ground under a roadway. An abrasive and/or explosive can be added to the high pressure fluid before it reaches the nozzles. The jetted flow from the nozzles can displace ground and exert pressure to detonate and cut mines and neutralize them on and under the roadway. Cavitation can be created in the jetted flow to increase the dynamic force of the jetted flow.

  • Patent number: 6870534
    Abstract: A method of simulating the effects of one or more explosive events utilizes a mapping of graphically-valued dots to describe the explosive event at detonation at a plurality of (x,y) positions. A degradation rule is applied to the mapping of dots at each of times tn, for n=1 to N, to yield corresponding mappings of degraded value dots. The degradation rule specifies how the mapping of dots at detonation changes with time. The mapping at detonation and mappings of the degraded value dots are then simultaneously displayed in (x,y) registration with one another.

  • Patent number: 6695068
    Abstract: A rocket propelled textile and cordage net fire extinguishing system is deployed from a platform at a safe standoff distance from a fire. The rocket propelled matrix-like net flies over, lands on, and drapes over the burning site. A detonating means, or detonating network on the net is actuated to rupture spaced-apart canisters on the net that are filled with halon and/or other fire extinguishing compounds. The detonating network quickly disperses the fire extinguishing compounds to engulf and extinguish the fire safely and efficiently without unduly exposing fire fighters to danger. The net fire extinguisher system can extinguish fires aboard a maritime vessel, particularly when the burning craft cannot be safely boarded or burns so fiercely that it cannot be approached closely. The net fire extinguisher system can combat highly dangerous fires including chemical and oil fires, (oil rig fires) on land and at sea.
