Under this topic, Advanced Cooling Technologies, Inc. (ACT) proposes to develop a software toolset to design and optimize the control architecture for two-phase thermal management systems. The approach with make use of physics based models to capture the component and system level response with high-fidelity. By building on previous successful modeling and experimental validation efforts, the rese ...

The utilization, and thereby, threat of unmanned underwater vehicles (UUVs) is experiencing a significant increase throughout the world. UUVs can be used to track vessels, covertly map ports, and attack targets. UUVs are inherently quiet targets making them difficult to track via traditional acoustic methods. To counter the threat presented by covert UUV activities, other detection and tracking me ...

Synthetic aperture radar (SAR) has the ability to detect and discriminate slow moving (= 10 knots) low radar cross section (RCS) objects such as small surface vessels and surface signatures in maritime environments at low-to-mid grazing angles. The physical mechanisms for detection and discrimination are made possible by the combination of coherent and non-coherent scatting phenomenology associate ...

Voci Technologies Incorporated (Voci) is the leading small business developing accelerated Human Language Technology based solutions. In Phase I of this SBIR, Voci demonstrated the feasibility of automatically clustering audio with useful false-positive and false-negative rates. In Phase II, Voci is is partnering with Vickers & Nolan Enterprises to develop a prototype Automated Speaker Clustering ...

In order to be an effective EM radiator, monopole antennas must be ideallywavelength. For HF frequencies, this can result in a significantly long radiator. This long radiator, when deployed, can accidentally contact a HV source such as an overhead power line. The results of such a contact can be devastating for the radio operator and potentially nearby soldiers. Because of this threat, a simple so ...

The general objective of this effort is to develop and optimize tungsten-based reactive materials (RMs) with the density equal to or greater than that of steel and with ignition and combustion characteristics improved substantially over existing tungsten-based RMs. The RMs to be developed will include individual reactive metal components mixed on the nanoscale to include structural heterogeneities ...

MaxPower Inc. is proposing the continued development of a lithium reserve battery for air-to-surface missile (ASM) applications based on their missile operational environment validated Lithium/Vanadium Pentoxide technology. The basis for this Phase II effort is the Phase I work performed on reconfiguring a reserve battery, originally designed to meet the requirements of the reentry vehicle on the ...

U.S. Navy ASW aircraft deploy sonobuoys across a mission field. The aircraft must then stay on-station for the duration of the mission to monitor, command, and receive data from the deployed sonobuoys. This requires a clear and uninterrupted channel of communications during all command downlink and data uplink transfers. The sonobuoy RF link is susceptible to interference, jamming, and eavesdroppi ...

In this SBIR program, Advanced Cooling Technologies, Inc. (ACT) is developing a PCM-based ocean thermal energy harvesting system to provide reliable, renewable, on-board electrical power generation for autonomous underwater vehicles (AUV). This scalable system harvests energy from the natural temperature gradients that exist in the ocean. ACTs novel design efficiently extracts heat from the surrou ...
