High-frequency acoustic modems are required to provide undersea communication networks to support covert surveillance operations. These modems can also be used as platforms for compact, low power surveillance sensors and processing. A natural first step would be to integrate a capability for passive acoustic detection of ships and submarines. A multi-phase effort is proposed for integrating passiv ...

In this Phase I DHS STTR proposal submitted in response to Topic H-SB06.2-007, Aymont Technology, Inc. and University of Virginia will develop gallium phosphide (GaP) avalanche photodiodes (APD) with high quantum efficiency (QE>50% at 360 nm in Phase I), high gain (>100000), and high speed (2 GHz bandwidth). This Phase I effort will build upon previous work in the Campbell group that demonstrated ...

To address the needs of emergency responders and incident commanders, a 4-D Emergency Response Tracking System (ERTS) is being developed to provide dynamic situational awareness in locating first responders and assets within building structures in urban environments. The proof-of-concept presentation will demonstrate how 3-D intelligent, interactive visual models of building infrastructure can be ...

To address the significant challenges being created by the rapidly expanding deployment of multi-spectrum sensors in large distributed surveillance operations, the feasibility, architecture design and interface standards are being investigated for a 4D Landscape Automated Situation Awareness(ASA) System. The proof-of-concept presentation will demonstrate how such a system can effectively manage la ...

One of the greatest challenges facing UGS networks is the availability of power to run critical processes. Most current technologies employ off-the-shelf batteries which require replacement every 6mnths or so. Battery replacement in a UGS deployment for border security is not only costly, but in some terrains nearly impossible. Ideally, UGS field components would harness power from the environment ...

There is an acute need for a networked chemical sensor that is inexpensive enough to allow it to be treated as a disposable item - deployed and left in-place until the end of its useful life, or until operations move out of communications range. Electrochemical microarray sensors can be fabricated at low enough unit cost to make the development of a disposable sensor node feasible. These sensors ...

Sample preparation has been recognized as the single most important challenge to be faced in the development of detect-to-warn (DTW) systems (NRC, 2005). Available commercial sample preparation technologies are expensive, slow (30 min to 2 hours) and require trained laboratory technicians for operation. Addressing this need, we propose to design, fabricate, demonstrate, and validate a novel integr ...

Current bioaerosol monitoring and evaluation systems are largely based on collection of airborne pathogens in a liquid medium, followed by the detection of the targets of interest. While available aerosol collection technologies employ large collection volumes, biosensors are capable of processing only a small fraction of the collection volume. Our overall objective is to design and demonstrate a ...

Our solution to the automated feature extraction problem will leverage the material properties that can be inferred from combining multispectral imagery with high resolution elevation data or LIDAR data using a trainable knowledge base. Multiple imaging bands provide a more complete picture of the material involved than ordinary RGB. This can help distinguish between a green grass lawn and a gre ...

This effort proposes to analyze and develop a design for the Secure Inter-organizational Network Boundary Assurance Device (SINBAD). SINBAD will leverage capabilities and leverage lessons from guard technology to yield an enhanced boundary control and inspection capability suitable for Homeland Security organizations exchanging inter-organizational email with attachments. It will 1) prevent improp ...
