Our Phase I work focused on improving modeling and simulations so that the impact of autonomous systems in the battlespace could be better understood. As we have trained our attention on Phase II, it has become increasingly clear that the work we are doing to improve the modeling and simulation of autonomous systems also provides significant leverage for the development of the intelligent behavior ...

Unmanned aircraft systems (UAS) are increasingly seen as a cornerstone in developing the future Defense infrastructure and it is critical that they collaborate efficiently and execute complex missions in denied environments. Although great progress has been made in GPS-denied navigation, the target handoff problem in GPS-denied environments has not been extensively studied. In this problem, a trac ...

Toyon Research Corp. and the Penn State Univ. propose research and development of innovative algorithms for classifying objects and activities observed in high-dimensional data extracted from multi-sensor motion imagery. The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets containin ...

The Global Positioning System (GPS) is vulnerable to radio-frequency (RF) sources of interference and must be defended through electronic protection (EP) measures such as anti-jam (AJ) and anti-spoof (AS). The Phase I effort investigated antenna, electronic, and algorithmic designs for systems capable of supporting direction-finding (DF) measurements while simultaneously performing anti-jam and an ...

The goal of this STTR effort is to design a portable, multimodal, non-contact imaging system for burn depth diagnosis and tracking of wound healing. UC and Vanderbilt University will build upon our previous efforts demonstrated via porcine model studies to combine results from structural B-mode optical coherence tomography (OCT) images and functional data (pulse speckle imaging- PSI) to classify d ...

An advanced Li-Ion Battery Management System for DOD mission and safety critical platforms. The majority of Li-Ion Battery Management Systems (BMS) for DoD aircraft, helicopter, and directed energy weapons are custom designs for the individual Aerospace platform. This leads to increased cost over the battery life cycle due to the requirement to maintain the production facilities which produce repl ...

LongWave Photonics, Massachusetts Institute of Technology and Virginia Diodes are proposing the use of the Terahertz Quantum-Cascade Lasers (QCL) combined with a Schottky diode detector for high dynamic range heterodyne imaging. Two single-mode, distributed feedback (DFB) QCLs with milliwatt power levels will be used as local oscillator and illumination for imaging. The QCLs will be downconverte ...

This Navy STTR Phase I proposal presents an unprecedented NDI tool to quantify mechanical properties of metal parts made with laser additive manufacturing with material characteristics and process parameters. A fiber laser SAW and heterodyne detection is used with LIBS to study both in-process and post-process for both flat and shaped parts. It is the enabling technology for characterize the AM pa ...

Based on our success in developing the world first commercial high energy femtosecond fiber laser system and our leading proprietary technology development in ultrashort pulsed fiber laser material processing, PolarOnyx proposes, for the first time, a compact high energy fiber laser based smart wound healing tool to meet with the requirement of this DHP solicitation. It includes a high energy fs f ...

This Navy STTR Phase I proposal presents an parallel AM tool to eliminate conventional scanning strategy. A 2D MEMS array is used to shape both in time domain and spatial domain to obtain the desired pattern for layer by layer process. Modeling is used to study in-process melting evolution versus powder and beam properties. It provides quantitative characterization of the AM system to guide the de ...
