| 20110168305 | NON-LETHAL PAYLOADS - Non-lethal payloads may be customized for particular uses and desired visual and audible incapacitation based upon the selection of igniter/activators and illuminants used with the non-lethal payloads. Non-lethal payloads employing high flame temperature igniter/activators and illuminants of powder metals, powdered metals combined with oxidizers, and powdered metals combined with heat-activated chromophores may produce improved “flashes” and “bangs” for non-lethal payloads used with diversionary or other devices. Such devices and methods of producing illuminance and noise are also disclosed. | 07-14-2011 |

| 20120118447 | Deflagration to Detonation Transition Device - A detonator assembly is provided. The detonator assembly comprises a deflagration to detonation transition body, a first thermally stable secondary explosive contained by the body, and a bulkhead coupled to the deflagration to detonation transition body. The bulkhead contains pressure within the body associated with firing the detonator assembly at least until a transition from a deflagration operation mode of the detonator assembly to a detonation operation mode of the detonator assembly has occurred. A second thermally stable secondary explosive may alternatively be included in the deflagration to detonation transition body, either separated from the first thermally stable secondary explosive or mixed with the first thermally stable secondary explosive. The detonator assembly comprises effectively no primary explosive. | 05-17-2012 |

| 20090178741 | Method Of Making Reactive Composite Materials and Resulting Products - Novel reactive composite materials and associated methods for making the same which are pertinent to numerous new or improved applications. The method for making the reactive composite materials utilizes mechanical deformation to manufacture such materials with controlled, predictable characteristics. In the first deformation step, an assembly of reactive layers and/or particles is plastically deformed to reduce its cross sectional area by one-half or more. Portions of the deformed sheets are stacked or bent into a new assembly, and the new assembly is then deformed. The steps of assembly and deformation are repeated a sufficient number of times that the resulting materials are only locally layered but have relatively uniform reaction velocity and heat generating characteristics predictable by stochastic models derived herein. | 07-16-2009 |
| 20100071813 | COMBUSTIBLE STRUCTURAL COMPOSITES AND METHODS OF FORMING COMBUSTIBLE STRUCTURAL COMPOSITES - Combustible structural composites and methods of forming same are disclosed. In an embodiment, a combustible structural composite includes combustible material comprising a fuel metal and a metal oxide. The fuel metal is present in the combustible material at a weight ratio from 1:9 to 1:1 of the fuel metal to the metal oxide. The fuel metal and the metal oxide are capable of exothermically reacting upon application of energy at or above a threshold value to support self-sustaining combustion of the combustible material within the composite. Structural-reinforcing fibers are present in the composite at a weight ratio from 1:20 to 10:1 of the structural-reinforcing fibers to the combustible material. Other embodiments and aspects are disclosed. | 03-25-2010 |
