M4 Engineering, Inc. and Sandia National Laboratories propose to create a unique bonded joint analysis and design software tool. Surrogate traction-separation models will be created that efficiently capture the behavior that occurs for real bonded joints. Mixed mode loading, including compressive normal tractions and relative displacements will be captured and used in an extended cohesive zone ele ...

In this proposal, we present Motion Imagery Exploitation with Compressive Sensing (MIECS), a system for improving the flow and exploitation of data gathered from wide-area surveillance. The proposed system exploits techniques from the recently developed field of compressive sensing compressive sensing for solving this problem. The system exploits significant temporal redundancy in captured data in ...

With the increased threat of shipboard fires, due to the use of composite structures, automated 3D fire control has become an important requirement. These sensors must provide fire detection and 3D localization that can trigger an automated firefighting response. Advanced Scientific Concept's (ASC) eye-safe 3D Flash LIDAR cameras provide a unique 3D imaging solution for fire suppression syste ...

The objective of the proposal is to demonstrate the feasibility of a generic package that provides high vacuum, temperature control and vibration isolation for a wide range of high performance (tactical and navigation grade) micromachined inertial sensors. Inertial sensors (accelerometers and gyroscopes) are now widely used in consumer and industrial applications. However, for high performance nav ...

Virtual EM is proposing a platform coupling technique for improving efficiency of electrically small antennas on ground, sea and air vehicles. The the proposed approach, a portion of the platform becomes the extension of the antenna and hence result in higher performance. Technique has been demonstrated already with the commercial automotive applications and a revised approach is proposed here.

OEwaves Inc. and AMO Physics Center of JILA propose to develop a novel monolithic ultra-stable portable whispering gallery mode resonator suitable for operation in a wide range of environmental conditions. The resonator will deliver the same performance as the best existing high-end laboratory Fabry-Perot resonatorswhich are large, expensive, and fragile table-mounted instrumentsbut in a robust 10 ...

We describe our efforts towards compact ultrahigh-Q 698-nm microcavity stabilization at 1e10-15 frequency instability at 1 second and chip-scale integration for portable precision optical lattice clocks. This advancement is based on state-of-the-art measurements and preliminary results by our team, enabled by the highest quality factor optical resonators (Q f 2e1010) measured to-date. The resonat ...

Continuous monitoring of body chemistries for metabolic monitoring, monitoring concentration of biothreats, early detection of sickness, and stress monitoring has the potential to enhance warrior performance. Currently available sensors are inaccurate and have short lifetimes, primarily due to the body"s foreign body response (FBR) to implanted materials. PROFUSA"s tissue-integrating sensor platfo ...

This proposal is to develop a new system for Adaptive Visualization of Social Networks (ADVIS). Numerous social network visualization systems have been produced in recent years. But even in the few top systems cognitive science and design principles have been applied in an ad hoc and non-systemic manner. Accordingly, each visualization system is a one-of, which may be fine-tuned to a particular ...

To address DARPA need to overcome the growing problems of co-site interference encountered in the modern military communications systems, RST Scientific Research, Inc. ("RST") proposes to develop a new low size, low cost low power closed-loop controlled high-Q frequency agile filter-bank assembly with RF channel select capability from 20 MHz to 30 GHz. The new filter-bank design to be inserted in ...
