This Phase II effort demonstrates the feasibility of integrating a chemically powered or “active” infrared (IR) treatment into an inflatable device and then perform three experimental excursions with the hardware: 1) achieve a tunable IR signature by cooling the surface; 2) achieve tunable IR emissions combined with a predetermined and fixed radar cross section (RCS); and 3) achieve both varia ...

The desired outcome of this STTR project is the development of compact, stand-alone, economical, and rugged pulse shaper units that can be used to control chemical reactions, and have a wide range of applications based on molecular control for detection of chemical and biological threats, explosive, and toxic chemicals. In addition, these units will enable a broad range of fundamental studies. Dur ...

A new material and processing technology is proposed that will dramatically reduce the cost of manufacturing lightweight mirrors for optical test applications. Such precision mirrors are also required for surveillance, directed energy, and DoD-sponsored space programs. There is a significant amount of research devoted to developing materials and processes for space-born mirrors and ground test use ...

Infrared counter-measures require a mid-infrared laser operating between 3-5 microns with average powers of tens of watts. Omni Sciences, Inc.'s (OSI's) aims to develop a Mid-Infra-Red FIber Laser (MIRFIL) based on super-continuum (SC) generation that produces a continuous spectrum between 1-5 microns. OSI has demonstrated broadband SC in high-nonlinearity fused silica (HiNL) and ZBLAN fluoride ...

The goal of the proposed research is to develop a highly sensitive, high-throughput, and miniaturized assay system for rapid detection of brain injury-specific biomarkers in serum. The assay will be integrated into a portable detector so results can be immediately communicated to the health-care provider for assessment and appropriate treatment of patient injury. This technology will be particul ...

Gel propulsion systems combine the best characteristics of solid and liquid propellants. The gel system stores like solid propellant, but flows like a liquid when pressurized, enabling throttle and restart capability similar to liquid propellants. An enabling technology for the further advancement of gelled propulsion is the development of tools to render the development of propellant formulation ...

Optical circuits provide many benefits for large time-bandwidth signal processing in microwave photonic applications. SeTapped delay lines using surface acoustic waves (SAWs) are in use today for carrier frequencies in the MHz to 100 MHz range, and thus their general theory and efficacy are well known. In order to be widely applicable, the tapped delay line filter must be robust enough to be dep ...

Auditory displays that encode spatial audio cues have advanced significantly in recent years, yet, their ability to convey the distance between a sound source and the listener remains limited. This Phase I SBIR project proposes to investigate algorithms capable of adding distance cues to natural and synthesized speech. The particular approach involves manipulation the speaker's vocal effort, wh ...

Virtual EM Inc. proposes to develop STAP techniques using machine learning algorithms for eventual implementation in critical radar systems. These algorithms require less time to train than neural networks. Virtual EM's simulation packages will be used to train the algorithms for array element failure, multi-path and jamming mitigation as well as interference from ground and maritime clutter. The ...

This SBIR Phase I will demonstrate the feasibility for a unitized component structural design tool that allows for holistic risk assessment. The analysis will transform the FEA predicted stress (or strain) state into fully probabilistic assessment of uncertainty in geometry and loading throughout the component. Thereafter the design tool will conduct probabilistic microstructural damage accumulati ...
