During Phase I, IFOS demonstrated the feasibility of using embedded optical Fiber Bragg Grating (FBG) sensor networks to measure resistance to penetration (for subsequent weapons) in concrete damaged by a weapon projectile. FBG sensors are well suited for monitoring dynamic strain in concrete structures due to their small size, low cost, ability to be embedded internally or surface mounted; and th ...

Orora Design Technologies proposes to develop electronic design automation (EDA) tools employing minimally invasive circuit design-based methods to mitigate single event effects (SEEs) for next generation Ultra-DSM CMOS (

The current DFU inlet exhibits poor aerosol sampling efficiency at high wind speeds. This project will develop an improved inlet with very high sampling efficiency for 1 to 20 micron particles at wind speeds up to 30 mph independent of wind direction. The project is focused on the DFU, but our Aerodynamic Next Generation Inlet (ANGI) will be beneficial for any high volume aerosol sampling applicat ...

Current high energy, multi-room test facilities operated in support of Defense Threat Reduction Agency (DTRA) efforts suffer from a lack of robust sensors that can provide a cost-effective approach to obtaining dynamic-pressure induced gas flow data during internal detonations events. Exquadrum, Inc proposes a new sensor package that utilizes existing piezoelectric sensor technologies, but incorp ...

The objective of this proposal is to develop enabling technology for the production of bulk scintillating nanocomposites that have gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings. These ‘ultra-composites’ w ...

To address the CBD need for a real-time measurement system for nonhuman primate tidal volumes, suitable for a Class 3 biological safety (BSL-3) cabinet, Physical Optics Corporation (POC) proposes to develop a new Respiratory Function Measurement (RFM) system. This system is based on a piezoelectric strain transducer that responds to movement of an animal’s thoracic cage during respiration. The ...

Aerius Photonics and partner Ahura Scientific, propose to develop a handheld system, based on Ahura’s successful FirstDefender Raman system, that employs an excitation laser emitting at 980 nm and a low noise InGaAs array based on Aerius’ high performance InGaAs technology. This system will substantially reduce the fluorescence present in CCD-based systems, and unmask otherwise obscured spect ...

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...

We propose a radically new approach to gamma scintillator materials based on high-Z polymer composites. These composites contain two key components molecularly dissolved in a polymer matrix that serves as the binder: (1) high-Z compounds for stopping high-energy gamma radiation; (2) luminescent conjugated polymers that functions as the scintillation activator. The molecular-level dissolution ensur ...

Based on the success of our Phase I feasibility research, we propose to continue the project for the automated objective speech intelligibility assessment system. It consists of a pair of head and torso simulators placed at the same distance as typical face-to-face communication, a power amplifier, a laptop computer, a speech recognizer, and console software. The simulator has acoustic properties ...
