Abstract: The beam method and the “slice” method for ship modeling are melded. The method uses a detailed ship model in the ship section immediately surrounding the system or equipment under study and a beam model for the portions of the ship away from the detailed ship section. This combined method has the advantage of providing a detailed section of the ship in the area of interest which allows for good system and equipment level modeling, and a course beam model of the ship everywhere else, which, in turn, allows for the ships mass and stiffness and hence frequency spectrum to be accurately represented.

Abstract: A projectile for penetrating hardened targets is provided to include a shell having a longitudinal axis substantially perpendicular to an impact surface of the target; and a plurality of penetrator elements disposed in tandem in the shell along the longitudinal axis. The penetrator elements may be composed of ceramic, which has high compressive strength relative to most metals. Selected portions of the penetrator may be composed of heavy metals. The penetrator elements may be separated from each other by gaps, which may be filled with foam or other shock-absorbing material. An alternate projectile provides a unitary penetrator element composed of ceramic.

Abstract: A method is provided for destroying a target that includes dispersing submunition fragments in an array that is directed to intercept the target, and engaging said fragments to collide against an outer shell of the target, wherein said array distributes said fragments as having a ratio between a characteristic length of said fragments and a separation distance of at most 2.5 and a collision velocity of between 1.8 km/s 2.0 km/s. The ratio is preferably at most 1.9. The characteristic length corresponds to a spherical radius of the fragment. Each fragment has a mass between 150 grains and 300 grains. The array is preferably aligned to intercept the target at an angle offset by between 15° and 45° from perpendicular to a longitudinal axis of the target. Each fragment has a preferable shape of a prism, a trapezoid or a pyramid.

Abstract: A process for separating entrained particles from a medium is provided. The medium flows into an intake port, through a separation region and out an exit port. The process includes disposing a separation region between the intake and outlet ports and positioning a magnet having north and south poles at opposite ends of the separation region. For orientation, the ports are disposed along a flow axis, and the opposite ends are disposed parallel to a pole axis transverse to the flow axis. The method operates by the magnet applying Lorenz force on the particles having one of positive and negative charges away from the separation region, wherein the particles avoid the outlet port without obstructing through the separation region. Similarly, a device for separating the particles is similarly described. In addition, the method and device further include a chamber being disposed adjacent to the separation region to collect the particles.

The first hanger is equipped for stowing, deploying and retrieving a self-propelled unmanned vehicle and is substantially disposed in the floating portion. The second hanger houses equipment for electrical power and on-board functions. The liquid storage compartment supplies fuel to the on-board equipment and to the unmanned vehicle. For static stability, the compartment is disposed in the submerged portion. The platform may also include a superstructure for housing sensor equipment. The superstructure can be disposed above at least one of the first and second hangers. The second hanger may additionally house a tetherable observation aerial post.

Abstract: A method is provided for determining fratricide probability of projectile collision from a projectile launcher on a platform and an interception hazard that can be ejected or launched from a deployment position. The platform can represent a combat vessel, with the projectile launcher being a gun, the interception hazard being a missile, and the deployment position being a vertical launch cell. The projectile launcher operates within an angular area called the firing zone of the platform. The method includes determining the firing zone, calculating an angular firing area, quantifying a frontal area of the interception hazard, translating the resulting frontal area across a flight trajectory, sweeping the projectile launcher to produce a slew angle, combining the slew and trajectory, and dividing the combined interception area by the firing area. The firing and interception areas are calculated using spherical projection.

Abstract: Various embodiments are described relating to devices and methods for detecting local human presence by olfactory reception of volatile organic compound (VOC) molecules dispersed in air. Such devices include a chamber inlet, a trap, a sensor and a communicator. The inlet receives the air that contains the VOC molecules, a trap for capturing the VOC molecules in the air. The sensor detects at least a threshold quantity of at least one of 3-hydroxy-3-methylhexanoic (3H3MH) acid and 3-methyl-2-hexanoic (3M2H) acid among the VOC molecules. The communicator provides notification of the threshold quantity. The methods include operations to receive the air, capture the molecules in the air, detect the 3H3MH and 3M2H acids, and signal notification of that detection.

Abstract: A particulate filter is provided for passing through select permeate particles in a fluid medium from inflow to outflow regions while restraining reticulate particles. The filter includes a coarse-grain ceramic porous substrate, an intermediate-grain porous ceramic layer, a fine-grain ceramic porous membrane, and a channel there-through. The substrate opens into the outflow region as an outflow cavity. The intermediate-grain porous ceramic layer is disposed on the substrate. The fine-grain ceramic porous membrane is disposed on the layer and opens into the inflow region containing the medium as an inflow cavity. The channel directionally expands and connects the inflow and outflow cavities together by a substantially funnel-shape passage. The inflow cavity permits the permeate particles and the medium but obstructs the reticulate particles.
