MEMS Based Chemicapacitor Sensor for Detection of Low Vapor Pressure Chemicals

Seacoast Science will continue Phase I efforts and fabricate a system for detection and identification of Low Vapor Pressure (LVP) Toxic Industrial Chemicals (TICS). The proposed system will include a microelectromechanical system (MEMS) chemical sensor array, sampling pump and a MEMS preconcentrator optimized for the selective and sensitive detection of a variety of high risk TICS that pose a threat to homeland security. Because of the diverse nature of these compounds we have designed a flexible system that allows for multiple modes of operation. The system will accommodate wall mounted or handheld operation and samples can be introduced from ambient air or by direct input from a swipe. Ultimately this program will yield a small, rugged, lightweight, low-power detection system. In Phase I we began optimization of our MEMS chemicapacitor sensors for some LVPs including a pesticide, explosive and mercury. In a Phase II design reviews we will expand the list of LVP TICS to include other high priority TICs. Our proposed MEMS preconcentrator provides high throughput and high collection efficiency while using minimum power. In Phase II we propose to integrate our sensors, a preconcentrator and a sampling system and to evaluate the system by exposures to LVP TICS.

Continuous Immunoassay for the Accurate Detection of Low Vapor Pressure TICs

Accidental spills or intentional releases of toxic industrial compounds (TICs) are significant threats to human life. Early detection and warning of the presence and distribution of these hazardous materials in the environment is very important in the prevention of injury and loss of human life. However, the monitoring for low vapor pressure TICS (LVTICs) in the atmosphere is problematic because these materials can be present in different forms that are not easily detected by conventional instruments. As part of a successful Phase I development effort, Intelligent Optical Systems (IOS) has demonstrated the feasibility of developing a system to sample and concentrate all forms of LVTICs in the atmosphere, and to continuously assay and detect LVTICs sampled from the atmosphere using a highly sensitive immunoassay technique. The goal of the Phase II work is to formalize and refine the design of the Phase I system to produce a tested and validated prototype capable of demonstrating the detection of LVTICs under conditions reflecting realistic monitoring and detection scenarios. In Phase II, displacement immunoassay protocols will be developed for additional classes of LVTICs, and a means to simultaneously monitor multiple classes of LVTICs will be constructed. A prototype bench level instrument, including an improved innovative air sampler, will be designed and fabricated to demonstrate the monitoring of LVTICs. At the end of Phase II, IOS will be prepared to market the monitor system to potential customers and to design the manufacturing processes needed to produce LVTIC monitors for sale to military and civilian markets.

Marine Asset Tag Tracking System

Advanced Marine Asset Tag Tracking System

iControl Incorporated
3235 Kifer Road
Suite 260
Santa Clara, CA 95051-0815


iControl`s Phase II effort completes the design of a prototype Maritime Asset Tag Tracking System (MATTS). The fully functional system includes shipboard satellite gateways, container TAGs, and secure Internet Data Center. The container TAG is a miniature sensor, data logging computer, radio transceiver, and inertial assisted GPS tracking system integrated into a compact inexpensive package. A TAG`s inertial estimator accurately resolves container locations even when sporadic or multi-path reflections corrupt GPS signals. The principal benefit of inertial corrected GPS, is an instrumented port or ship is not required to record container location. An iControl container TAG can store its location history with no supporting infrastructure. The container location (and its history) are reported when the TAG is in range (up to 2 km) of an Internet gateway equipped ship or dock. To implement the reporting network, self contained, low cost satellite gateways will be installed on each container ship. Ports will be equipped with low cost Internet linked gateways to provide real-time container tracking for inventory management. Phase II will include tests and integration of the system at an overseas port. Containers will be instrumented and tracked during loading, trans-pacific crossing, and unloading.

Handheld Lobster Eye X-Ray Inspection Device

To address the U.S. Coast Guard (USCG) boarding teams' need for a safe and noninvasive handheld inspection instrument that can accurately analyze and visualize materials aboard ships hidden from view behind walls, Physical Optics Corporation (POC) proposes to develop a safe, compact, handheld Lobster Eye X-ray Inspection Device (LEXID) capable of through-the-wall real-time imaging of hidden objects. LEXID is based on POC's hard X-ray imaging technology, and will efficiently collect hard X-ray Compton backscattering photons from a hidden object irradiated by a full cone beam from a low-power X-ray source. The lightweight handheld LEXID can be used aboard small ships without danger to personnel, at an irradiation dose <10 microsievert per hour of continuous inspection. In Phase I POC experimentally proved the LEXID concept by fabricating a bench-top prototype and demonstrating its performance. In Phase II a handheld working prototype will be designed, assembled, and tested in the laboratory and at USCG testing facilities. The prototype will be robust in marine environments, will penetrate 75 mil metal walls while drawing just 10 W of battery power, and will deliver real-time through-the-wall imaging of illegal cargo with resolution better than 1 mm and an SNR>30. POC`s LEXID technology will find many applications in noninvasive container inspection for security screening in airports and at marine terminals and border checkpoints, and for nondestructive evaluation of product quality by X-ray screening. LEXID will also have a variety of military applications, including through-wall observation of hidden compartments, and mine and bomb detection.

Improved Security Information Management for SCADA Systems

Expert Microsystems, Inc.

Orangevale, CA 95662-2120


Expert Microsystems will increase the scope of its cyber-security surveillance solution beyond intrusion detection systems to include other intelligence sources-firewalls, routers, server logs, and packet sniffers for performing dynamic packet filtering of the SCADA protocols themselves. We will develop a software solution that eliminates 99.9%+ of false positives generated by today's surveillance solutions, identifying true threats and breaches with greatly improved accuracy, and increasing the efficiency of limited cyber-security personnel. An extensible product will be developed that enables future plug-ins for additional SCADA protocols and security enhancements. The solution will be applied to power transmission and distribution, and municipal water applications. Wide deployment within these industries will be assured by developing two product versions-a full-featured version for entities with sophisticated cyber-security resources, and a simplified version for organizations with limited or constrained resources. Ease-of-use, total cost of ownership, and customer input will be priorities during all work tasks-successful commercialization and wide deployment is given the highest priority. Our Phase II customers will be DOE's Western Area Power Administration (manages power grid for fifteen states), San Juan Water District (community services district in Northern California), and EPRI (pending funding approval) who represents our nation's electric utilities.
