This device comprises at least one explosive charge (3) able to project at least one metallic block (7) in the direction of the projectile. The device is characterized in that the block or blocks (7) are in the shape of elongated bars, that is which have a maximal length greater than or equal to 10 times their smallest crosswise dimension, the explosive charge (3) being position opposite a longitudinal surface of the bar (7).

Abstract: There is provided dual use body armor that can be alternately used either as a hand held shield which can be concealed in a standard bag (such as an attache case) or worn as an armor vest, and which can be quickly converted from one use to the other. For this reason the shield would normally be of an approximately rectangular shape. The exact shape may be varied in order to fit in different types of carry bag, or to better conform (for the purpose of comfort or protection) to the shape of the body when unstowed or deployed and worn as a vest. When used as a vest, the invention is preferably comprised of two or more armor panels that unfold or deploy to protect an area of the front and back, and preferably also the side and lower abdomen, of the torso. The front armor panel, back armor panel, side armor panels, and lower abdomen armor panel, are all located on the body by means of a support system.

Also provided are methods of deploying the hypervelocity shields using said apparatuses.

Abstract: An impact resistant structure is described which comprises a substantially sinusoidally shaped elastically collapsible open-celled fluted layer disposed between but not bonded to constraining layers, whereby in an impact event, the flutes are free to move between the constraining layers and stress concentrations in the collapsing flutes immediately beneath the impacting object are minimized by the absorption of impact forces by neighboring flutes that resiliently collapse in an accordion-like fashion, and return substantially to the original shape after impact without permanent damage to the structure.

Abstract: Silicon infiltration technology is used to produce ceramic bodies having utility as ballistic armor. In a first aspect of the invention, the ballistic armor includes a reaction-bonded silicon carbide body (RBSC). Good ballistic performance can be advanced by loading the permeable mass or preform to be infiltrated to a high degree with one or more hard fillers, and by limiting the size of the largest particles making up the mass. In a second aspect, the silicon infiltration technology, e.g., siliconizing or reaction-bonding, is used to bond silicon carbide fibers to at least the back surface of a ceramic armor body, thereby enhancing ballistic stopping power. A third aspect of the invention pertains to the ability to engineer RBSC bodies such that there is little dimensional change during processing, thereby permitting high dimensional reproducibility in large-scale production.

Abstract: To ensure that a camouflage structure will not lose its effectiveness even in changing temperatures (day/night, sunshine/clouds) when protecting against reconnaissance in the IR range, the camouflage structure features varying emissivity tendencies in the atmospheric windows II (3-5 um) and III (8-14 um). In other words, the emissivity in the IR range is not constant and at a certain level, but it has an increasing or decreasing tendency in at least one selected spectral range.

Abstract: A portable ballistic barricade comprises a ballistic shield blanket attached to a portable, collapsible ladder.

The blanket may also be rapidly removed from the ladder and used to cover an explosive device.

Abstract: A composite body produced by a reactive infiltration process that possesses high mechanical strength, high hardness and high stiffness has applications in such diverse industries as precision equipment and ballistic armor. Specifically, the composite material features a boron carbide filler or reinforcement phase, and a silicon carbide matrix produced by the reactive infiltration of an infiltrant having a silicon component with a porous mass having a carbonaceous component. Potential deleterious reaction of the boron carbide with silicon during infiltration is suppressed by alloying or dissolving boron into the silicon prior to contact of the silicon infiltrant with the boron carbide. In a preferred embodiment of the invention related specifically to armor, good ballistic performance can be advanced by loading the porous mass or preform to be infiltrated to a high degree with one or more hard fillers such as boron carbide, and by limiting the size of the largest particles making up the mass.

The panel may be a part of the door that is between the cockpit of an airplane and the region in the airplane rearwardly of the cockpit.

Abstract: The invention provides camouflage in both the visual spectrum and the infrared spectrum by emulating the infrared radiation of an object's background and the visible radiation of an object's background, effectively cloaking the object from detection. Initially, the temperature and color of the background against which an object appears is determined. The external surface of the object, or alternatively a shield around the object, is then heated or cooled using thermoelectric modules that convert electrical energy into a temperature gradient. The ability of the modules to be either cooled or heated permits the output of the modules to be altered to match the temperature of an object's background. In combination with these thermocouples, the invention utilizes choleric liquid crystals to alter the visible color of an object.
