21CT and CUBRC propose CEDAR (Complex Event Discovery, Analysis, and Ranking), a robust framework to detect and analyze indicators of complex activities, such as an insurgent ambush observable via myriad of simple events in multiple sensor streams. CEDAR will provide a mapping from complex behavior, such as conducting an insurgent ambush or rebuilding trust in local communities, to simple event in ...

Research in silicon photonics has received much attention in recent years for its potential to utilize well developed silicon processing technology. A broad range of linear and nonlinear silicon photonic devices such as modulators, splitters, switches and detectors have been demonstrated. However, the most important challenge in silicon photonics thus far is the difficulty of making electrically p ...

APS has assembled a world class team to address problems associated with rail gun launcher operation. APS has combined its unique processing experience with IAT's railgun design, testing and characterization experience to develop materials to improve rail gun performance. Phase I will be devoted to fabrication and testing of various samples in rail gun conditions. Phase II will focus on the manufa ...

The U.S. Navy has initiated a program to develop the next-generation Joint Counter Radio Controlled Improvised Explosive Device Electronic Warfare (JCREW) 3.3 system to detect and jam enemy improvised explosive devices (IEDs). The objective of this proposed effort is to develop the manufacturing processes and antenna designs needed to integrate a wideband metamaterial antenna within the ballistic ...

The promise of printed electronics can not be realized without high-speed manufacturing processes to drive the cost down for wide spread distribution. This proposal will outline the key points for rapid manufacturing of new electronic devices and systems and make recommendations for making them a reality. There are two main focus areas that encompass all the limitations to printed integrated circu ...

In this program, Omega Optics and the University of Texas at Austin propose to develop an on-chip surface-enhanced Raman scattering (SERS) spectrometer array for single molecule detection. The sensitivity of the SERS spectrometer comes from the 5-nm gap between gold nanowires, which can achieve 108 enhancement factor (EF) for the Raman scattering signals. Especially, these gold nanowires are preci ...

Having realized the bottlenecks in electronic systems-on-film manufacturing, Omega Optics and the University of Texas at Austin propose to develop a low-cost, high rate, roll-to-roll manufacturing process for hybrid electronic systems on flexible substrates. Roll-to-roll fabrication of hybrid systems enables the utilization of the combined advantages of organic, inorganic and other material system ...

TRACLabs Inc. has worked with NASA to create indoor/outdoor, vision-based leader-following systems for sparse, extra-terrestrial environments. Brown University's Robotics Group has demonstrated leader-following and gesture recognition in high-traffic, dynamic, indoor environments using active lidar sensing. We propose to combine our technologies in order to create a passive sensing system that w ...

The current produced in electrochemical galvanic cells is primarily dependent on the rate of the electrode reactions where the cell's anode is less negative, supplying less energy than thermodynamically predicted, and the cell's cathode is less positive, supplying less energy than thermodynamically predicted. Reduction of electrochemical overpotentials in electrochemical systems has been the prim ...

Areas of research relating to self-healing composites structures have been undertaken by well-known and respected institutions under the auspices of the Department of Defense. Patent literature and public technical communiqué describe their novel engineering approaches using microencapsulated systems that release polymeric healing agents through suitable mechanisms. While these approaches have me ...
