  • Patent number: 7159823
    Abstract: A rapid deployment system has an inflatable landing tube with an inflatable exit slide coupled to an aircraft. Connectors couple the landing tube to the aircraft. Flexible retarders extend inward from the inner surface of the tube for retarding gravitational descent of cargo and/or personnel from the aircraft. The tube has tubular segments, with ribs and reinforcements, forming a continuous descent tube. A spine along the tube is retractable telescopically allowing for the tube to be retracted within the aircraft. The tube is connected to exterior edges of any exit port of the aircraft. A window coaming adapter is positioned around the exterior edges and a membrane extending between sides of the adapter expands with the landing tube as the landing tube is inflated. The membrane is of multiple layers with expansion cells between adjacent layers for allowing independent expansion of the layers. The entry port has a shield behind the membrane and connected to the aircraft for protecting the membrane.

  • Patent number: 5620058
    Abstract: An emergency evacuation system uses three primary concepts--Retarded Free Fall, Temporary Structures and Energetics--to provide for rapid, safe rescue. An inflatable descent tube with entry ports is installed along the side of a structure or at the top of an elevator shaft. In emergency situations, a gas generator connected to the tube is activated and inflates the tube with gas. The interior surface of the tube includes energy absorption structures strategically positioned to retard the rate of fall. The structures absorb energy from falling bodies and translate some of the vertical force to horizontal force as the evacuee is temporarily deflected sideways in the tube. Friction strands cover the surfaces of the structures to further reduce velocities of falling evacuees. An inflatable exit ramp is positioned at the bottom of the tube to cushion the fall of the evacuee and lead the evacuee to safety.

  • Patent number: 5479736
    Abstract: An augmented service pistol weapons system and ammunition has an extended barrel and an adapter sleeve and mount which supports the barrel and partially surrounds a forward end of the service pistol. Two hinged flaps have inward extending clamps which engage an inside of the front of a trigger guard on the pistol. A turn-to-release locking pin holds the two flaps together as the flaps are closed on the trigger guard. An arm rest extends laterally rearwardly along sides of the pistol and terminates in a curved rearward extension to support the augmented service pistol on an arm of the user. A fifty round magazine replaces the standard pistol handle magazine. Scopes and aiming devices are mounted above the extended barrel. A foregrip is removable and positionable at opposite lateral sides of the extended barrel and below the barrel. A variable power function assembly surrounds the barrel and allows selected release of gas to slow projectiles. A shredding device near the muzzle shreds bands on the projectile.
