UUV"s have become increasingly important tools in the collection of environmental data. Their unique ability to operate independent of surface vessel conditions allows artic measures when traditional means is not possible. It is now well agreed that artic regions are critical to man"s understanding of the environment. Historically sensor packages for UUV"s have been based on"adaptions"of ship depl ...

We envision a coherently coupled QCL array architecture featuring 2nd order DFB gratings to vertically couple out light with excellent beam quality and high output power. This approach does not require cleaving of the devices or facet coatings and is therefore inherently more robust and manufacturable than facet emitters.

The low weight, excellent durability and heat resistance of ceramic matrix composites (CMCs) make them attractive materials for use in aircraft engine hot sections, where improved overall engine efficiency can be realized. Nevertheless, the interlaminar properties of CMCs must be well understood before CMCs can realistically replace metallic superalloys in engine hot sections, and no standardized ...

The rare-earth elements (REEs) find uses in many high tech military applications, including night vision goggles, laser range finders, precision guided weapons, and stealth technology. Their high costs (up to $6800/lb. Scandium) are due to low concentration in ores and high cost of separation. Fourteen of the REEs are listed in a single box in the periodic table, meaning they all have almost iden ...

In this Phase I SBIR proposal, Reactive Innovations, LLC will demonstrate the technical and economic viability of a room temperature environmentally friendly technology for extraction and separation of light rare earth metals (lanthanides) with improved efficiency. Rare earths currently require multiple separation steps to yield high purity material. Decreasing the number of separation processes ...

Metal Oxygen Separation Technologies, Inc. proposes a 6-month SBIR Phase I project to demonstrate feasibility of using molten salt electrolysis with a zirconia solid electrolyte to cleanly and efficiently produce dysprosium metal from its oxide. This Phase I project will have as its goal the design of a molten salt-zirconia-anode system in the context of an electrolysis cell for producing high-pu ...

Submarine commanders must make complex decisions to accomplish increasingly diverse missions. Moreover, concurrent missions may involve contradictory requirements. Planning must also account for the unexpected, including equipment failures, environmental factors, or external events that impact the ship's mission(s). Since all submarine operations involve a degree of risk, the commander must b ...

The OASIS/WHOI team will design and develop a long-range under-ice acoustic navigation and telemetry system. The Phase I work has resulted in a much-improved model for under-ice acoustic propagation and an in-depth exploration of the potential for regional scale (200-500 km) acoustic navigation and communication. Phase II work will focus on bounding the design problem and selecting a suitable freq ...

Functional encryption (FE) is a new vision of public key encryption that allows access controls to be embedded within a ciphertext. This project has three main components: (1) develop an FE toolkit and FE-based key management service, (2) conduct essential cryptographic research to support deployment, and (3) explore opportunities for interoperability and integration for FE with existing and futur ...

The team consisting of Eos Photonics Inc. and MIT Lincoln Laboratories will develop a MWIR laser source based on a high power, continuous wave (CW) Quantum Cascade Laser (QCL) array. The output from the array elements will be beam combined monolithically using a unique spectral beam combining technique. The combined outputs will reach power levels exceeding 25 Watts with excellent beam quality (M2
