摘要:
An inflatable trajectory altering and blast energy absorption system has a plenum with walls that are spaced apart from one another when the plenum is inflated. Flexible members, dispersed in the plenum and coupled thereto, are placed in tension when the plenum is inflated. Means for altering the trajectory of a projectile entering said plenum are dispersed within the plenum.

A detonation arrestor cuts the detonating cord of a dud line charge to prevent the pressure wave from a nearby explosion from sympathetically detonating the dud line charge. A housing of the detonation arrestor has a transverse passageway to receive the detonating cord of the dud line charge and an axial bore intersecting the passageway. A cutter piston having a cutter blade is disposed in the bore and is sized to permit axial displacement by a shallow dish-shaped diaphragm spring. The diaphragm spring has its center adjacent to one end of the cutter piston and laterally extends from the bore to be secured to the housing along its round periphery in a sealed relationship. The diaphragm spring is formed in the configuration of a Belleville spring from a spring material providing strength, rigidity, and spring modulus to snap to an extended position when displaced to a position past an over center position by an impinging pressure wave. When the diaphragm spring is displaced by the impinging pressure wave to snap to the extended position, it axially displaces the cutter piston in the bore to cut the detonating cord with the cutter blade and arrest detonation of interconnected ordnance.

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.

An inflatable body armor system has one or more body armor sections adapted to be worn by a user. Each body armor section includes (i) a inflatable flexible/sealable plenum, (ii) a ballistic armor fabric encasing the plenum, and (iii) a variety of lines, shaped objects and/or fabric sheets dispersed in the plenum to alter the trajectory of a projectile entering the plenum.

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.

A system for arresting a fleeing seagoing vessel deploys a net using one or more self-propelled vehicles from a platform. The net is flown over and draped onto a seagoing vessel of interest such that a portion of the net's periphery resides in the water. Drag devices are coupled to the net to generate drag forces at the portion of the net's periphery in the water as the seagoing vessel moves through the water. The system can also include a variety of non-lethal weapon systems that are coupled to or incorporated with the net, and designed to subdue the crew of the vessel and/or the vessel's engine and electronic components.

A convertible toe strap for securing a toe area of a snowboarding boot is selectively and repeatedly convertible between different restraining configurations. The convertible toe strap includes a first configuration where one of toe lift or forward movement is resisted and a second configuration where both toe lift and forward movement is resisted.

A boot incorporating techniques for making the process of tightening and loosening the laces of a boot more convenient for the wearer is disclosed. The boot may be provided with at least two independent lacing zones, the tensions of which are separately adjustable by the wearer. The zones may be secured by pulling on two laces, each of which tightens one of the two independent lacing zones. This arrangement allows the wearer to simultaneously tighten each zone, providing the wearer with the “feel” as though he or she is tightening a conventional single lacing zone boot. The laces may be simultaneously, yet independently secured by a lace lock at the upper and/or forward region of the boot. Slack may be created to facilitate loosening of the boot and easy removal of a foot from the boot by unhooking the lace from the lace guide without a corresponding distance of lace traveling through the lace lock. A release strap, graspable by the wearer, facilitates unhooking the lace.
摘要:
The present invention is directed to the cloning, sequencing, expression, and characterization of an immunoreactive ferric binding protein (Fbp) (38-kDa) protein of Ehrlichia canis encoded by a polynucleotide therefor. In particular embodiments, the protein is employed in an immunogenic composition, such as a vaccine. Methods to induce an immune reaction in an individual with compositions of the invention are provided.
