Abstract: A means is provided for defending a target from attack by a torpedo with high probability. When a controller detects a torpedo based on an image generated by a sonar, it specifies a path of movement of the torpedo. If there is a water craft or the like within the path of movement, the controller instructs a launcher to launch a torpedo capture device and instructs mines to switch to detonation-off mode. Moveable devices of the torpedo capture device launched by the launcher in accordance with the instruction of the controller move in the water to spread a net. The controller then specifies a location of each of a first moveable device and second moveable devices based on an image generated by the sonar, and instructs the first moveable Device and the second moveable devices to move such that the center of the net is within the path of movement of the torpedo. The first moveable device and the second moveable devices move in accordance with the instruction of the controller.

Abstract: A security barrier is presented for preventing unauthorized persons or vehicles from easily crossing a border. In one preferred embodiment, the security barrier is suitable for installation in a waterway and comprises: (1) a plurality of piles, each pile having a bottom end embedded into the earth and a top end extending vertically upward; (2) an open security grid juxtaposed between and secured by the piles, wherein the grid preferably has a bottom end that extends downward below the surface between the piles toward the earth; (3) at least one rigid wall panel also juxtaposed between and secured by the piles on top of the open security grid, thereby forming a security barrier that allows water, air, aquatic life, and birds to pass through the barrier, but restricts the movement of humans and vehicles across the barrier.

Abstract: A marine barrier has substantially vertical panels, each having a buoyant portion, and a plurality of hinges, each hinge for elastically connecting a side of a first one of the panels to a side of an adjacent second one of the panels with an included angle therebetween, to form a buoyant continuous pleated row of panels, with the hinges arranged in first and second substantially parallel rows. An impact cable is attached to opposing ends of the pleated row of panels passing through each of the hinges in the first row of hinges. When the barrier is floating in water and a moving vessel impacts the impact cable, the impact cable deflects to transfer a force of the impact to one or more of the panels, which in turn engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.

Abstract: An unmanned aerial vehicle (UAV) recovery system comprises a base and a pneumatic capture net, including a set of upwardly extending, flexible, inflatable tubes, supported by a capture net support assembly. Drag forces are exerted on a UAV by the set of tubes when the UAV flies into them. In some examples the recovery system includes a plurality of decelerators, each decelerator having a supply of a restraint strap, connected to the pneumatic net, which can be pulled from the decelerator upon the application of a sufficient force so that movement of the pneumatic net is resistible by forces exertable by the decelerators on the pneumatic net.

Abstract: A floating structure includes a water pollution preventing membrane having a float part extending so as to define a water area, and a curtain part suspended at a lower end of the float part to define the water area in water. A float net having floatable ropes anchored to the float part and knitted into a lattice with a predetermined mesh size is disposed in an outer water area defined by the water pollution preventing membrane. Of the ropes constituting the float net, the rope which is disposed in parallel to the float part has a light reflection rope and a support rope for supporting a trap net suspended into water. The propeller of a watervehicle moved into the float net is caught by part of the ropes or the trap net to prevent the watervehicle from approaching the water pollution preventing membrane or an inner water area.

Abstract: A structure or vehicle protection method including a removable frame on the structure or vehicle, and a net within the frame and spaced from the structure or vehicle and having a mesh size designed to disarm an incoming threat.

Abstract: Embodiments of this invention describe a float for use with a running gear entanglement system (RGES) deployed on water, in addition to an improved system and method for using an RGES deployed in water. The floats lock securely onto the RGES mainline rope. The floats may be stacked for additional buoyancy or to allow for multiple RGES ropes in the same deployment. The floats are designed to permit the RGES to be retrieved/stored on and deployed from a reel. The floats may be constructed of any color and may also be luminescent. The floats may be ballasted to assist in anchoring the RGES.

Abstract: A barrier for stopping unwanted watercraft and subsurface intruders from entering into a port or off-shore structure is provided. In one embodiment, the invention is a barrier comprised of a vertical net structure supported from the sea floor. The barrier comprises vertical supports and a net assembled between the vertical supports with a system of ropes and energy absorbing devices. The structural components of the barrier are designed and configured in a manner as to absorb and displace the kinetic energy generated by an explosive laden small watercraft traveling at a high rate of speed. In another embodiment, invention is a barrier system installed around the perimeter of a water side or offshore facility. This barrier system comprises a bottom founded perimeter fence having a gate system and a series of barriers comprised of a vertical fence structure supported from the sea floor.

Abstract: The port security barrier includes multiple barrier float assemblies connected to one another to form a barrier to stop, delay and discourage attacks by high speed boats of sixty five feet or less in length on high valued waterfront assets such as ports and docking facilities. The port security barrier includes multiple barrier floats coupled to one another by flange connectors. Each barrier float assembly also has a capture nylon net which is used to capture the high speeds and prevent an intrusion into restricted waters.

Abstract: There is disclosed herein apparatus and methods for protecting ships and harbors from attack from other vessels. A barrier, fence or obstruction is constructed around the ship or harbor to be defended, either floating on the surface above and/or beneath the surface of the water. When a boat attempts to force its way through the barrier, the barrier uses the momentum of the vessel against itself by using the forward momentum of the attacking vessel in such a manner as to divert, impede, stop, damage or destroy the vessel or mitigate a blast from a vessel. The barrier may be active or passive. Also, a constructed wall of water can be provided to stop, destroy or disable a vessel attempting to go through the wall.
