DHS and the military have an urgent need for sensitive detectors of harmful materials such as toxic industrial chemicals, explosives, and chemical and biological warfare agents. Handheld instruments must be sensitive, able to detect a wide variety of target compounds in a matter of seconds, reliably discriminate between innocuous and harmful compounds, and be relatively inexpensive. A technology with great promise for addressing all of these requirements is miniature ion trap mass spectrometry (MIT-MS). These relatively simple devices are capable of detecting, identifying, and quantitating target compounds with great sensitivity and high levels of confidence. Mass spectrometry, nearly unique among analytical instrumental methods, combines high sensitivity with generality, i.e., applicability towards all compound classes, thus offering the high molecular information necessary for confident identification. One of the biggest factors preventing the development of truly low-cost and portable MIT-MS is the cost and size of the high vacuum system required for its operation. Creare proposes to address this by developing an innovative, miniature, rugged, vacuum system.

Hand-held gamma ray spectrometers are a vital tool for detecting and identifying nuclear materials to counter the threat of radiological and nuclear terrorism. The HPGe crystals in these detectors must operate at cryogenic temperatures to achieve good energy resolution. We propose to develop an innovative, miniature cryogenic cooling system that will be ideal for hand-held detectors. High efficiency will enable long battery life, and low vibration will improve the detector sensitivity. In addition, the system will be lightweight and inexpensive to produce. In Phase I, we will prove the feasibility of our approach by building and demonstrating critical components and producing a conceptual design for a prototype cryocooler. In Phase II, we will build and demonstrate a complete prototype system. Homeland security applications include nuclear materials interdiction, safeguards inspection, and emergency response. The cooler can also be used to cool portable x-ray detectors and infrared sensors used in military targeting and guidance systems. The commercial nuclear industry can use the cooler/detector for in-situ waste assay measurements, nuclear reactor maintenance, and health physics.

A low cost Swimmer Detection Sonar Network (SDSN) is now being developed under an ONR Phase 2 SBIR and as a joint project between the USA and Singapore. The SDSN is a network of inexpensive sonar nodes where narrow sonar beams are formed using air-backed parabolic reflectors. The feasibility of the system has been proven through trials conducted in Singapore harbor and full development is well underway. Currently each parabolic reflector has a single transducer at the focal point and is used for both transmission and reception. There is one parabolic reflector for each beam, with up to 10 beams per node. A substantially less complex, cheaper, and smaller node might be realized using a single wide-beam transmitter and a multi-beam air-backed spherical reflector receiver. Initial modeling shows promise. The Phase 1 effort would include more thorough modeling, testing of a multi-beam air-backed spherical reflector receiver, and design of a complete node. In Phase 2 we would build up 3 nodes and evaluate their performance against the current design. If successful this SBIR would make the SDSN even more cost effective, allowing for its use in a much broader range of applications, along with significantly increasing the commercial potential.

A laser-based acoustic emission (AE) detection device is proposed for structural stability assessment of buildings in order to provide warning of structural instability or pending collapse. It will help to reduce injuries and fatalities during emergency mitigation operations. This new device will take advantage of innovations in laser ultrasonics, artificial intelligence (AI) and advanced acoustic emission technology to provide the user with a unique instant real-time stability assessment of the building structures in-situ, which was not attainable in the past. The research will also result in a unique non-contact AE monitoring device, which will be very useful in many areas of application. The primary objective of the Phase I research is to demonstrate and evaluate under laboratory conditions the concept of the laser device for stability assessment, and to construct a prototype setup for further development and optimization in the subsequent Phase II research. In contrast to conventional visual inspection, the proposed development, if successful, will provide an instantaneous, more accurate and reliable objective assessment for building stability based on scientific parameters detected in-situ. A huge market will be developed in the emergency mitigation and management sector once the product demonstrates its superior function over the visual inspections.

Surveillance systems record spatially and time-referenced sensor data, such as video imagery. With a growing need to monitor larger regions for longer intervals, there is a corresponding geometric growth in the size of the four-dimensional time-space surveillance recording. Tools that allow efficient exploration of this time-space are key to extracting value from the surveillance data. The critical problem is to preserve spatial context and causal time correlation while providing timely access to vast amounts of distributed data. We propose an innovative solution that extends 3-D map viewers such as Google Earth to add a 4th time dimension. These 3-D maps are a recent innovation of their own-they access geospatial data on demand from a vast, distributed database. Our innovation adds on-demand time-history distributed surveillance imagery to 3-D maps, and enables the capability to "fly through" a seamless 4-D time-space world. The end user implementation is easy and intuitive to use-a simple "time throttle" is added to the existing spatial navigation controls of the map viewer. The proposed scalable time-space surveillance technology will greatly improve the efficiency with which meaningful data from large distributed surveillance systems can be acquired, monitored, and reviewed. We thus enable more efficient use of limited resources, and quicker response in time-critical situations. The benefits to safety would have applications in homeland security, military and industrial facility monitoring, and home security systems.

Surveillance of remote border areas is a significant problem. Detection of walking or running subjects is currently performed using multi-modal unattended ground sensors that measure seismic, acoustic, passive infrared (PIR), and magnetic activity. Current systems rely primarily on the seismic and PIR sensors as they provide the greatest detection range. However, these sensors are prone to false alarms as they can not effectively distinguish between human and animal activity. These false alarms are particularly problematic in remote areas due to the manpower required to investigate each alarm and the abundance of wildlife. During the course of this project, Creare will continue to develop and refine our novel feature-based intruder detection and discrimination algorithms. These algorithms, designed for use in unattended ground sensors, have already shown promising results when used to discriminate between human and animal data.
