High power fiber lasers have made significant progress in the last several years. Ten kW of diffraction-limited output power at 1 micron from one single mode fiber has been demonstrated. Department of Defense (DoD) needs 100s of kW for missile defense as well as for protection against rockets, artillery, and mortars (RAM). There is serious concern about current 1 micron fiber laser system potentia ...

In 2009, Virtual Learning Technologies received an award to develop Frachine, a web-based single player fraction learning game for elementary school students. This project will develop an intelligent tutoring system that will integrate with the existing game to provide the individualized instructional support required to further improve student math outcomes. Phase I will develop a prototype of t ...

A cooling system that converts waste heat from power supply units into useful space cooling is sought by the U.S. Army to reduce the electrical loads and fuel consumption in mobile military platforms. Unfortunately, conventional heat actuated systems are too large and inefficient. ThermAvant Technologies has developed a thermally-driven cooling system that combines environmentally benign fluids wi ...

This Phase I STTR effort develops and tests spectropolarimetric surface characterization algorithms for LADAR based remote sensing. A systematic approach is used which first defines the operational scenarios for which the algorithms are to work. These scenarios are then used to define requirements for LADAR hardware and algorithms which serves to focus the algorithm development effort. A librar ...

We plan to develop a Virtual Radio Frequency (RF) Environment for testing Command, Control, Communications (C3) systems. Testing the large tactical C3 systems requires fielding hundreds of nodes and providing thousands of signals/messages to meet the operational requirements. This is very expensive and often the large numbers of systems are not available. Our Virtual RF Environment (VRE) would all ...

The DataSoft Network Obfuscation and Virtualized Anti-reconnaissance system (NOVA) detects hostile network reconnaissance and denies access to real network information while simultaneously providing false network information to attackers. This results in attackers expending significantly extra time and effort, allowing defenders additional time to mount an appropriate response. NOVA is a novel dis ...

For the Phase I effort, Global Engineering and Research Technologies (GERT) will develop a validated methodology to predict damage initiation and growth or durability of composite materials under cyclic loading in extreme temperature conditions. This effort will demonstrate the feasibility of the proposed method by considering both laminated or woven composite materials while including the effect ...

For IR sensors, the sensing detector and readout circuitry (ROIC) are commonly joined on a pixel by pixel level in a process referred to as Hybridization. Hybridization requires bonding an ROIC die and a detector die on a pixel level, where the total number of pixels required to bond and form interconnects ranges from 1,000,000 to 16,000,000 individual pixels. The material of choice for Hybridi ...

The objective of the proposed research and development work is to create two new types of ultra-compact, energy efficient, high voltage switches. These switches will be used to deliver the energy from power supplies that store very small (0.5-5 J) amounts of prime energy to loads of different types. es. The overall dimensions of switches of both types will not exceed 20 mm. The operating voltage d ...

Advanced turboshaft engine impeller disks work at a high rotational speed at elevated temperatures which vary from the disk rim to its bore. Due to contact with combustion gases, the rim possesses a significantly greater temperature than the bore. This temperature gradient implies different requirements for the mechanical properties of the material in the rim and bore areas. A nickel based superal ...
