摘要:
A non-lethal projectile has an enclosed frangible shell with a nose assembly coupled thereto. The nose assembly is designed to be frangible and absorb shock energy incident on the nose assembly. Frangible containers disposed in the shell occupy a portion of the volume defined thereby such that spaces between the containers are defined. Each container is configured to divide into particles when the container fractures. Each container contains at least one payload material. A gelatinous carbomer fills the spaces between the containers.

A multi-level security software architecture includes various components configured to provide full data separation across multiple processors while limiting the number and size of high assurance components. The architecture includes a domain separator for ensuring that messages exchanged between domains that are distributed on different microprocessors are securely routed between domain members. The domain separator verifies a message label including a domain identifier provided by a domain gateway and cryptographically binds the message label to each message via cryptographic keys. This prevents misrouting messages caused by accidental or malicious corruption of message labels. Additionally, the domain separator can encrypt messages as necessary to enforce data separation on shared network buses. The domain separator is also responsible for managing the cryptographic keys used to label or encrypt messages.

A fuel depot and method autonomously and clandestinely provide fuel for transiting ships. An elongate streamlined flexible bladder member has flexible hull walls and divider walls separated by uniform spaces to form fuel compartments having a fuel valve and fuel pump. The bladder member can transit submerged to a remote destination. A fuel and water tight composition in and along the spaces prevent fuel and water leaks to ambient water and between the compartments. A submersible propulsion system has propulsive machinery and steering gear for towing the bladder member. A command/control system on the submersible propulsion system generated and couples driving signals to the propulsion system to tow and steer the bladder member to the remote destination using the preprogrammed computer, inertial navigation system (INS), global positioning system (GPS), and RF transceiver of the command/control system.

An air-delivered submersible vehicle system has a monocoque-construction shell made from a fiber-reinforced plastic material selected from the group consisting of thermoplastics and thermoset plastics. The shell is equipped with a wing kit so that it can be deployed from an aircraft and fly through the air to a destination at a surface of a body of water. The shell is further equipped as a submersible vehicle so that it can be propelled through the water once it has reached its water destination.

An integrated water sensing actuator is based on a fibrous cellulosic material having anisotropic moisture-absorbing properties such that it's dried-in strain is greatest along one axis thereof. A plug of the dry and compressed fibrous cellulosic material has a powder material coated thereon and mixed therewith. The plug is compressed along it's axis of greatest dried-in strain and is fitted in a water-permeable housing adjacent a piston. The powder material is inert with respect to the cellulosic material and initiates a chemical reaction when exposed to water such that a product of the chemical reaction is water. Immersion of the housing in water causes expansion of the plug and corresponding movement of the piston.

An underwater high energy acoustic communications device has inner shell-like structure having an outer surface connected to first ends of tuning springs and outer shell-like structure having an inner surface connected to second ends of the tuning springs to concentrically locate and space the inner and outer structures apart. Explosive units mounted on the inner surface of the outer structure each includes an explosive squib, rigid tube, and projectile. A micro-controller feeds firing signals over electrical leads to the explosive units to detonate them and fire their projectiles to strike the inner structure that emits ringing high-energy broadband acoustic signals that are propagated into surrounding seawater. A transducer connected to the micro controller receives acoustic signals from a remote source to activate the micro-controller to generates preprogrammed sequences of firing signals to propagate coded messages by the high-energy broadband, acoustic signals.

A line charge for deploying explosive charges across obstacles and mines to clear a safe lane has explosive charges spaced apart on a common detonating cord, and axial passageways in the explosive charges are sized to permit free longitudinal travel of the detonating cord through them. A composite strength member includes an inner fabric sleeve of high strength flexible material covered by an outer sleeve of thermoset/thermoplastic material and contains the explosive charges and detonating cord. Heat-curing the inner fabric sleeve and outer sleeve shrinks and conforms them to the outer contours of the explosive charges and combines the high strength flexible material and thermoset/thermoplastic material. Composite strength member absorbs energy during deployment of the line charge over its entire length and circumference and absorbs more energy prior to structural failure to allow the use of more powerful rocket motors to fly longer line charges from much greater and safer standoff distances. Composite strength member does not transfer self-destructive strains to the detonating cord during deployment; the detonating cord is free to longitudinally slide through the explosive charges; and composite strength member maintains proper spacing of explosive charges so that explosive effectiveness of the line charge is maximized. The cost effective and uncomplicated assembly procedure for the line charge creates a more reliable line charge having improved performance capabilities as compared to contemporary manufacturing schemes.

A vehicle is provided for drone stowage and transport as a means to extend the range of smaller drones and unmanned underwater vehicles. The transport vehicle is launched from a mother ship and provides for moving drones and underwater unmanned vehicles to desired launch and recovery points. The vehicle is based on current hovercraft vehicles and is adapted for stowage of drones while remaining compatible with existing mother ships. The vehicle includes foldable deck sections, which can be extended to provide launching and landing runways for flying drones. Lifts and ramps are incorporated for loading, launching and recovering flying drones, floating drone vessels and underwater unmanned vehicle drones.

A variable shock wave bio-oil extraction system and method utilizes shock waves to separate oil, water, and biomass from feedstock in a single step. In one embodiment, at least one pair of opposing transducer arrays are arranged in a shock wave extraction housing and collectively powered by a pulse controller to create controllable shearing planes and/or shearing regions and/or shock stem zones to interact upon a flow path of feedstock as the feedstock travels through the shock wave housing.

A moisture-absorbing material and method of making same are provided. Hollow fibrous tubes of cotton are sequentially dried, combed in a direction to substantially longitudinally align the hollow fibrous tubes of cotton, and stretched, twisted about and compressed in this direction. A powder material can be mixed with the hollow fibrous tubes of cotton. The powder material is inert with respect to the hollow fibrous tubes of cotton and initiates a chemical reaction that generates water when exposed to water.
