Physical Sciences Inc. (PSI) proposes to design, develop, and demonstrate a portable, non-invasive, real-time sensor to assess the chemical and physical health of solid rocket motors as a function of age without affecting the motors integrity nor having direct contact with the propellant. In Phase II, a sensor to monitor specific gas species that are markers of the chemical and mechanical aging pr ...

This Small Business Technology Transfer project will develop a mathematical framework and enabling technologies for context-aware target classification and selection for missile defense systems in the presence of counter-measures and clutter in realistic scenarios. Based on statistical relationship learning (SRL) methodology, the proposed framework can reason simultaneously about multiple entries ...

Combining information from disparate sensors can lead to better situational awareness and improved inference performance; unfortunately, traditional multi-sensor fusion cannot capture complex dependencies among different objects in a scene, nor can it exploit context to further boost performance. Integrating context information within a fusion architecture to reason cohesively about scenes of inte ...

Programs such as Airborne Laser and Space-Based Laser require highly mass efficient structures. Because of their high specific strength and stiffness this naturally leads to graphite fiber reinforced polymer (GFRP) materials for many system components. In fluid storage tank applications GFRP laminates often develop microcracking when subject to cryogenic temperatures and/or stresses due to press ...

This MDA STTR Phase II proposal is a continuation of the work started in Phase I where we proposed to employ ionically self-assembled monolayer (ISAM) processing methods for the fabrication of interconnection joints for high temperature packaging of power electronics devices. The ISAM technique is a recently developed revolutionary method which provides nanoscale control of structure, density, and ...

The team of Physical Sciences Inc. (PSI) and Ohio State University (OSU) proposes to develop and demonstrate a novel electrically generated singlet oxygen to atomic iodine laser. In Phase I we developed and demonstrated a novel discharge method for production of singlet molecular oxygen and completed a design for a supersonic transfer laser. In Phase II we propose to extend this work to develop ...

In partnership with MIT, AeroAstro will continue the development of a highly innovative lightweight, inexpensive, low power star tracker for small satellite applications. No solution currently exists currently in this area of the trade space. The design developed in Phase I takes advantage of the processing capabilities embedded in newer CMOS imagers to reduce power consumption and limit the amo ...

This Phase II proposal focuses on the development of a data-driven, integrated damage diagnosis and prognosis technology to enable on-line, accurate and useful failure predictions for ABL systems. The developed software system will utilize the advanced nonlinear dynamics based signal analysis and dynamics reconstruction methods to identify active damage modes, track their evolution, develop approp ...

During this Phase II STTR, Foster-Miller will develop Yttria-Alumina-Garnet (YAG) IR windows made by our innovative process and establish a property database to confirm the potential for cost-effectiveness and superior optical and mechanical properties compared to current materials. This YAG is made from a single crystal YAG preform and hot pressed to >99 percent density. Windows made during Ph ...

The terahertz wave region of the electromagnetic spectrum offers exciting and unique attributes for security imaging and secure broadband communications. However, THz signal generation is difficult and current applications are rare. Existing THz sources utilize large and expensive lasers operating in pulsed mode. Practical application of THz radiation requires the development of THz source techn ...
