A frustum embedded fabricated composite protective structure is provided, including a restraint frame, a back plate, an infill block and a buffer block. The restraint frame is provided with a plurality of mounting holes matching with the shape of the infill block, the restraint frame is arranged on the back plate, the infill block is in a frustum shape. The buffer block and the infill block are installed in the mounting hole of the restraint frame, the buffer block is arranged on the smaller end of the infill block, and the infill block is wedged into the mounting hole of the restraint frame through a wedge surface mating. Because this protective structure is assembled by multiple restraint frames and infill blocks, under the prestress restraint of partition blocks, the damage range after penetration or explosion will be significantly reduced, and it can withstand multiple blows.

The invention is the first modification of the Patent Application with number 1009231 and involves an additional system of three levels which reinforces and improves the dynamic armor of main battle tanks using compressed ferromagnetic powder and electromagnetically reinforced. The main characteristics of the first invention (DE-1009231) for the armor system of tanks and battle vehicles was the use of compressed powder from magnetized or non-magnetized ferromagnetic pulverized materials (Fe, Ni, Co) or other similar synthetic materials that enrich or enhance the desired mechanical properties and the effect of electromagnetic amplification between two solid passive armor plates. The first level (FIG. 1, 2) concerns the placement of high temperature silicone or other material of the same mechanical properties at a suitable thickness proportional to the threat, between the outer passive solid shielding plate and the compressed ferromagnetic powder. The second level (FIG. 1, 3) concerns the modification of the layer containing the ferromagnetic powder by the distribution of the ferromagnetic powder contained in pellets or cubes or rectangular parallelepipeds or other basic geometric volumes from polymeric material with viscous elasticity or other kinds of material with same mechanical properties of thin walls or alternatively its placement in a spatial network with cubic or conical or spherical partition volumes with thin walls made of polymeric material with viscoelasticity or other material with the same mechanical properties and then compress them between the plates of solid passive armor. The third level of reinforcement (FIGS. 1, 4) was achieved by placing a layer of explosive material on the visible side facing to the ferromagnetic powder of the inner passive solid shielding plate in combination with percussion, perforation and temperature sensors. The layer of the explosive may be in a single layer or be contained as based on the inside surface of each individual area of the spatial network or similarly to separate cubes or rectangular parallelepipeds.

New forms of suppressive gunfire decoys are provided. In some aspects, a pin-pull device may be used to program and adjust several settings of the decoy devices, activating such devices immediately before deployment. In some aspects, the pin-pull device may serve as a remote control unit. In a preferred method of deployment, the devices are thrown to a location different from that occupied by the user(s), simulating another source of gunfire, distracting and misleading an enemy, and providing the effects of suppressive fire. In some embodiments, a networked computer system(s) may be used as a remote control unit, and the decoy device may include cameras and other sensors for tactical surveillance. In still other aspects, the gunfire decoy device may be capable of locomotion, and may be self-relocating in response to certain commands, or in reaction to stimuli, to confuse the enemy regarding sources of gunfire and troop locations.

Armor systems are described. Armor systems include an armor that includes a container, in which the container includes a bottom, a top and sides and is enclosed, hollow spheres that are placed in a stack in the container, explosive that is wrapped around each of the hollow spheres in the container, in which the explosive-wrapped spheres substantially fill the container.

This invention related to a method of and system for detecting a threat, particularly a threat to a vehicle associated with an explosive blast and/or detonations. The method typically comprises receiving electromagnetic signals, or data indicative thereof, via a suitable electromagnetic detector arrangement from a target area adjacent the vehicle, as well as receiving optical signals, or data indicative thereof, via a suitable optical sensor arrangement also from a target area adjacent the vehicle. The method then comprises generating a threat detect output in response to receiving an optical signal indicative of a threat subsequent to receiving an electromagnetic signal indicative of a threat. The system typically implements the method as described. The invention also extends to a vehicle comprising a system in accordance with the invention.

Apparatus and methods for reducing injury or damage from an explosive device are disclosed. An example apparatus includes a housing and at least one inflator coupled to the housing. The apparatus also includes a shield coupled to the housing. The shield has a plurality of channels coupled to the at least one inflator. The shield also has a compact position and an expanded position. The plurality of channels are configured to receive a fluid from the at least one inflator and thereby at least partially advance the shield from the compact position to the expanded position.
