Abstract: A process for producing a metal foam. The process includes mechanically working a metallic powder such that oxide particles and/or dissolved oxygen are finely dispersed within a metallic matrix of the metallic particles that make up the metallic powder. The mechanically worked metallic powder is then annealed in a reducing atmosphere, where the reducing atmosphere is an atmosphere that results in the reduction of oxide and/or dissolved oxygen into vapor or gas molecules such that intraparticle porosity is formed within the metallic matrix by conversion of the oxide particles and/or dissolved oxygen to create vapor or gas molecules.

Abstract: This invention relates generally to a chitosan-graphene oxide membrane and process of making the same. The nanocomposite membrane can filter water and remove contaminants without fouling like other commercially-available polymer-based water filters. The membrane can be used as a flat sheet filter or can be engineered in a spiral filtration module. The membrane is scalable and tunable for many water contaminants including pharmaceuticals, pesticides, herbicides, and other organic chemicals. The membrane uses chitosan, which is low-cost, renewable biopolymer typically considered to be a waste product and the second most abundant biopolymer on Earth, thus making the membrane an environmentally-friendly product choice.

Abstract: A polymer layering process that encapsulates and protects electronics components with complex and imprecise geometries. The protective layering process provides a combination of a flexible mold and/or a rigid mold that apply close-forming, encapsulating the polymer layers to the electronic components and precision assemblies. Polymer layer protective jackets are shaped to as-populated circuit boards and assemblies, providing tightly fit barriers with fine resolution accommodating imprecise geometries. The protective jackets can be formed in rigid, semi-rigid, or highly flexible polymer films, to protect the circuitry from the elements, CTE mismatches, shock and vibration loads and extreme g-forces, and external electromagnetic emissions. By altering the protect layer configuration, the protective layer can accommodate populated circuit board assembly with high heat generation component(s).

Abstract: An improved system and method for generating high Voltage within an ESAD munition fuze is provided. Conventionally, high voltage transformer conversion circuits used within ESAD munition fuzes utilize a flyback, or step-up transformer. The use of a flyback, or step-up transformer reveal technical limitations when used for the application of increasing arm charge times, voltage conversion efficiency, and power conversion efficiency for ESAD munition fuze applications. Alternatively, the use of a high voltage inductor conversion circuit utilizing an inductor, in combination with a switching transistor allows for a new and improved low cost method for improving ESAD munition fuze applications with respect to generating high voltage from a low voltage source onto a detonator firing capacitor to trigger a Low Energy Explosive Foil Initiator (LEEFI) within an ESAD munition fuze.

Abstract: The impact angle of a small caliber projectile is determined by accurately measuring the orientation angle of the projectile in flight and modeling epicyclical flight of the projectile. To measure the orientation angle, a projectile is fired along a trajectory within a test gantry. One or more sets of cameras captures images of the projectile in flight. The images are processed using computer vision to measure the position and orientation angle at each station. Calibration of the test equipment prior to the test firing of the projectile, allows for determination of these points in the 3d space of the test fixture. Aeroballistic models are fit to the orientation history. From these models, an impact angle is extrapolated.
