The widespread use of communication devices and radar systems has made our society increasingly vulnerable to disruptive, high-power, short pulse electromagnetic interference (EMI) and high power microwaves (HPM). Significant advances in devices that produce these high-power, short pulses have been made in the US and abroad in the past few decades. As a result, the need for devices that can prot ...

Accurate Automation Corporation’s main objective of the SENTINEL SYSTEM is to provide a 24/7 presence on the water without putting valuable human resources in harm’s way. Capable of being controlled remotely or configured for autonomous operation, the SENTINEL SYSTEM is an attractive solution to a range of marine applications. The SENTINEL can interdict threats in the maritime and littoral ...

Accurate Automation Corporation (AAC) will address the integral operation of a USV with multiple UAVs. Such a system leverages the advantages of both platforms while compensating for the limitations of each. The USV provides range and endurance, deploying the UAVs across a long distance or after long periods on station. The USV also provides sensor coverage of the underwater environment, of whi ...

The subject of this proposal is a heat exchanger based on variable conductance heat pipes (VCHP) that will provide a passive, valve-less means of regulating process gas temperatures in reformers for fuel cells. A key component of the Navy fuel cell system is the reformer, which converts diesel fuel into methane for consumption by the fuel cell. Reaction temperatures are critical to proper functi ...

Advanced Materials Corporation proposes to optimize the process to manufacture soft magnetic materials that are anticipated to be superior to M19 steels both in magnetic induction and in electrical resistivity. Proof-of-concept studies conducted during Phase I have demonstrated the superior magnetic properties of the new material in comparison to M19 steel. Further optimization studies are propose ...

Thermal batteries are often the battery of choice when very long shelf life is needed, and accessibility to the battery is limited. Improvements are sought for achieving improved electrochemical performance, lower cost, and building batteries in conformal shapes. Unfortunately, present manufacturing processes make it difficult to meet these goals. The purpose of this proposed work is to make low ...

This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient an ...

We propose to use a gas fed vertical style sublimation reactor that can accommodate several different types of chemistries and be modified to a number of different approaches. The reactor is similar to the HTCVD reactor developed by Linköping University and Okmetic. The approach will be to initially try out different chemistries at fairly high temperatures where sublimation is a dominant process. ...

The development of long SiC boules grown from the gas-phase using chlorinated halo-hydrocarbons faces enormous technical hurdles that must be overcome. The hurdles of specific interest are the outlet, the materials degradation, and the inlet. Caracal proposes to find a solution to all of the above mentioned technical obstacles. The outlet is of particular importance since it limits the length of t ...

The objectives of this Phase II program are to demonstrate the feasibility of high frequency Tonpilz transducers utilizing PMN-PT single crystal “32” mode resonators poled along . TRS will prepare and characterize the properties of the “32” mode samples by determining the full property matrix for this special crystal cut. These measurements will be based on IEEE standard techniques. NAV ...
