In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

Maintaining accurate position location information (PLI) during operational missions is a critical requirement for the dismounted soldier. This requirement is unmet in heavily forested and jungle environments where GPS reception is unavailable due to dense canopy cover. In such environments, soldiers must determine their location by using visual landmarks, or by seeking open clearings where Global ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

Electron microscopy of specimen in liquid has recently been demonstrated by Niels de Jong at Oak Ridge National Laboratory (ORNL). A sample was enclosed in a liquid compartment with electron transparent windows and imaged using a scanning transmission electron microscope (STEM). Expanding on this expertise it is proposed to develop the technology of a liquid holder for both TEM and STEM that prov ...

The military needs better methods of monitoring remote facilities to protect them against burglary and vandalism. Many of these facilities cover large areas, contain numerous buildings and other valuable assets, and are at high risk for theft. New acoustic monitoring technologies are needed that will allow deployment of large numbers of low-cost, autonomous sensors. Each sensor must provide rel ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

Scientific Solutions, Inc. (SSI), teamed with BAE Systems and Southall Environmental Associates, Inc. (SEA), proposes to investigate the feasibility of using commercially available active sonar to autonomously identify and track marine mammals from transiting SURTASS-LFA surface ships at ranges out to and beyond 2,000 yards. Active sonar has been proven effective to detect and track marine animals ...

Reliable ignition is critical to the operational performance of augmented military engines. Augmentors must reliably ignite when thrust is needed or system (and pilot) safety could be compromised. Augmentor ignition is particularly challenging relative to other combustion systems because the ignition system must function over an extremely wide range of conditions. Optimizing existing igniter syste ...

The Navy requires compact high-power inductors to match single crystal transducers to their power amplifier drives for efficient, compact sonar operations in Unmanned Underwater Vehicle (UUV) applications, where volume and power are at a premium. Enabling more efficient UUV sonar operation will increase vehicle operational availability. Creare proposes to develop advanced, compact power inductors ...

Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. Legacy Flight Deck Cranials are inadequate in many aspects including hearing protection, impact protection, cleaning, comfort, and compatibility with night vision devices (NVDs) and with chemical, biological, and radiological (CBR) equipment. In this p ...
