A floating barrier system has a plurality of connected floating barrier units. Capture net segments are positioned on the floating barrier units by support post members, forming a barrier to vessel passage. Lanyards attach the ends of the capture net segments to the floating barrier units. Upon a vessel striking the capture net segments with sufficient force, the capture nets detach from the support post members and/or pull the support post members over, and the forces from the vessel are transferred via the lanyards to the floating barrier unit. The vessel is prevented from fully passing over the floating barrier unit, thus itself forming a barrier to passage by other vessels.

A system is provided for automatic operation and status indication of a marine barrier gate. Embodiments include a system having a buoyant barrier gate that is movable between a closed position and an open position. An actuator moves the gate between the open and closed positions, and a sensor is operably connected to the actuator to generate data relating to a position of the barrier gate between the open and closed positions. A processor receives the data from the sensor and processes the data to move the gate between the open and closed positions, and detect the position of the gate. A human-machine interface is operably connected to the processor for communicating the detected position of the barrier gate to a user.

The present invention comprises a plurality of UUVs, tethers and tethered devices. The devices that are tethered comprise explosive devices or acoustic devices. The UUV provides mobility and controllability for the tethers and the tethered devices. The tether is also used as a means to entangle target vessel's propeller. The entangled propeller's revolution moves the explosive device closer to the target vessel for denotation. The tether is made with high strength material whereby once entangled, it is difficult for the propeller itself or intervention to disentangle. The system has a detachable housing with fluid dynamic shape. The whole system is designed to submerge during operation. The system can be wirelessly controlled by a remote command center via satellite link, or by a nearby command center directly.

A marine barrier has buoyant panels elastically connected with an included angle therebetween, to form a pleated row of panels with hinges arranged in first and second rows. An impact net having cables is attached to a net connection portion of each hinge in the first row. The net connection portions are attachable to the cables with a tension such that, when the barrier is floating and a moving vessel impacts the net, an impact force causes the cables to move relative to the net connection portions, transferring a portion of the force of the impact to the net connection portions, until cable stops on the cable ends engage net connection portions adjacent the cable stops. The force of the impact is then transferred to the panels, which engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.

A security barrier system for controlling boat access to a protected area includes a barrier having an opening through it for boat passage. The barrier may be a fixed structure such as an earthen berm, or may be a floating barrier. A pair of spaced-apart support members, fixed in the waterbottom, are on either side of the opening. A gate is connected to one of the support members and spans the opening. A remotely operable latch means locks the gate closed, preventing passage. In one embodiment, a boat remotely unlocks the gate and pushes the gate open, then flex members return the gate to a closed and locked position. In another embodiment, particularly for locations with significant water level changes, the gate moves vertically on floats in response to water level, and a remotely operable system both unlocks/locks the gate and moves it between closed and open positions.

A strap and tensioning mechanism for attaching flotation modules to sections of Port Security Barriers (PSBs) is disclosed. Preferably, the strap is made from non-metallic fibers, preferably in an axially aligned or linear configuration, to form the strap, the fibers preferably being made of Aramid. Other strong synthetic fibers exhibiting desired thermal and other properties are suitable, as well.

The present invention relates to a mobile protection system for moored or anchored ships. The system has a reinforced foldable surface unit and a foldable net unit connected to the surface unit to provide a restricted area. The surface unit prevents small boats from entering the area and the net unit prevents divers from entering the area. The net unit is provided with an alarm to indicate if a diver tries to penetrate the net.

A protection apparatus protects a harbor or an area in a body of water or adjacent to a body of water. The protection apparatus floats on the body of water, and includes a plurality of barrier units positioned side-by-side, each of the barrier units includes a composite-based durable barrier structure. The barrier structure is configured to hold a net in place in order to protect an area in the body of water or abutting the body of water from waterborne craft. The protection apparatus also includes connectors respectively provided between adjacently-positioned ones of the barrier units. Each of the connectors includes a tensile member and a dampening member for handling forces applied to the protection barrier and for maintaining the integrity of the protection barrier.

Circuit and method for determining the presence of a load in a circuit including on a charge pump. The circuit monitors the state of a pump signal indicative of the operating status of the charge pump. The circuit generates a signal indicating the presence or absence of a load. The signal is used to deactivate features of an associated device, thereby reducing the power consumption and extending the life of the power supply (e.g., battery) for the device.
