High-Efficiency, Dual-Mode Air Sampler

Research International, Inc

Monroe, WA 98272-1034


A compact aerosol sampler is proposed that uses novel centripetal virtual impactor principles to segregate the collected particulates into large (>10 microns) and respirable (0.5 - 10 microns) 'bins'. The approach integrates the key components into a single, monolithic, injection-molded structure that is low in cost and easily scaleable from the baseline 100 LPM sampling rate. The flow rates of the two secondary channels are only 5% of the primary airflow. The segregated and concentrated particulates from each channel may be captured into either a dry (filter) matrix or a wet (aqueous) matrix. System modeling indicates the device will only consume about 5 watts and the project manufacturing cost is $500. Such an air sampler is needed for the detection and identification of biological materials in a number of arenas. Foremost is the need to protect infrastructure and populations from bioterrorism. Additional markets are air quality monitoring of public spaces, hospitals, 'sick building' syndrome and agricultural facilities such as brooder houses.

Micro-Machined Aerodynamic Lens Aerosol Concentrator for Particulate Sampling

Enertechnix, Inc.
P.O. Box 469
Maple Valley, WA 98038-0469


The proposed project will develop a novel aerosol concentrator based on aerodynamic lens technology capable of achieving very high concentration factors in a compact device, fabricated using micro-fabrication methods to achieve low cost, compact size, high reliability, high throughput, and extremely high precision and repeatability. In this project we will develop Computational Fluid Dynamic (CFD) models of fluid flow and particle trajectories. We will fabricate prototype lenses, arrays, and complete aerosol concentrators using micro-fabrication techniques; we will test those lenses using inert aerosols and simulant bio-aerosols to determine device performance and effects on organism viability; and we will make detailed comparisons between CFD modeling predictions and the experimental results. We will develop collaborative arrangements with one or more BAND contractors and will design and fabricate a commercial prototype aerosol concentrator and interface it to one or more BAND analyzers. For the commercial prototype we will utilize a fabrication method suited to mass production at very low cost per device. In conjunction with the BAND contractor, we will test our commercial prototype aerosol concentrator and document its performance. Our device will be applicable to a wide range of particulate sampling markets including security, environmental monitoring, military, and industrial pollution control.

Advanced Bioaerosol Sampler for Continuous Surveillance

Many integrated biodetection systems require an aqueous sample, with the notable exception being those based on mass spectrometry which frequently uses a dry sample (MALDI or pyrolysis). The proposed air sampling system (BioXC) to be developed is amenable to dry or nearly dry sample collection, but can deliver a final sample in an aqueous format autonomously. The automated system will filter out particles larger than 10 microns, concentrate and collect particles between 1 and 10 microns, and elute the sample to a small volume of liquid (<1 ml). Furthermore, the proposed system offers significant operating and cost advantages relative to more conventional wet-walled cyclones in use today for homeland security and military applications. Another common sampling technique in use today is dry filtering, but this approach is not amenable to fully-autonomous operation. Several subsystems will be optimized and developed to provide pre-filtration, concentration, collection, and elution. These subsystems will be integrated into an autonomous system which performs dry collection of aerosols with automated elution of the sample for analysis. This integrated system will result in a sampler that can be integrated with a broad range of advanced bio-detection technologies including mass spectrometry, microchip arrays, PCR and immunoassays.

A Novel Method to Produce Very Low Cost Basic B AIS Transponders

Shine Micro, Inc.

Suite A
Port Ludlow, WA 98365-8269


The MTSA of November 2002 recognized the urgent need for AIS (Automatic Identification System) in the US. AIS is needed to track vessels for surveillance, safety of navigation, and collision avoidance. Class A AIS is a step in the right direction, but falls far short of what is needed. For AIS to be truly effective it must track all or at least a large percentage of vessels. Class A AIS costs too much to be widely deployed on small and pleasure vessels. In Phase I of this project Shine Micro, Inc. designed and built 10 Alpha prototype Basic B AIS units. They are lower in cost than any other AIS. In Phase II of this project we propose to finish the Basic B AIS design, prepare for production, perform field-testing to prove the performance of CS-TDMA technology in an SOTDMA environment, and continue to participate in the IEC AIS standards process.

Wide-area Toxic Industrial Chemical Decontamination

Isotron Corporation
1443 N Northlake Way
Seattle, WA 98103-8994


The purpose of this SBIR effort is the demonstration of concept and deployment of a novel method of large-scale decontamination of Toxic Industrial Chemicals (TICs). The Phase I effort demonstrated both neutralization and removal techniques for dealing with decontamination. The decontamination system couples a Strippable Vapor Encapsulation Coating ("ISOLOCK-VC") with a hybrid inorganic/organic decontamination sol-gel. In some cases, a two step decontamination process while in others, decontamination could be affected in one step. The Phase I effort successfully demonstrated Proof-of-Concept. This Phase II activity will advance the technology to field scale trials and pilot-scale production and will deliver at least two TIC neutralization protocols for wide-scale use.

Phase II: The BioSonics UnderWater ACoustic Sentinel (UWACS), a Low Cost Underwater Threat Detection System

BioSonics, Inc.
4027 Leary Way NW
Seattle, WA 98107-5045


The purpose of this Phase II project is to develop, build and test a fully functional, multi-node UnderWater ACoustic Sentinel (UWACS) production prototype system for homeland security applications. The UWACS system is intended to detect and classify divers (and other human intruders) underwater and on the surface in harbors, ports, and other waterside sites susceptible to such intrusion. BioSonics has been an industry leader in the field of sonar for fisheries and underwater habitat assessment for 28 years. In Phase I, BioSonics succeeded in developing, building and field testing a research prototype UWACS active acoustic system, capable of detecting, locating and tracking underwater swimmers and surface craft at ranges greater than 300 meters in complex, shallow, saltwater environments. In Phase II, the UWACS research prototype system will be enhanced to support multiple networked scanning acoustic nodes, simultaneously providing data to the master control unit to allow adaptive wide sector coverage. BioSonics will develop a user friendly Graphic User Interface (GUI) to enable complete system configuration capability, surveillance sector visualization, target assessment and localization. System data output protocols will be industry compatible. The commercialization potential of the BioSonics UWACS system for homeland security, defense, public and private sector markets is tremendous.

Trace Explosives Sampling for Vehicle Borne Improvised Explosives Device (VBIED) Detection

HSHQDC09C00131 0812009
(FY08.1 Phase II)

Enertechnix, Inc.
P.O. Box 469
Maple Valley, WA 98038-0469


Enertechnix proposes to develop a sampling system for trace explosive particles and vapors for vehicle-borne improvised explosive device (VBIED) detection and related applications. Our approach combines forced air jets for dislodging particles and vapors from the vehicle surfaces, with concentration and collection of dislodged particles and scavenging of explosive vapors on artificially introduced aerosol particles with mesoporous surfaces (possibly containing selectively adsorbent polymers tuned to the molecular characteristics of explosives). These particles will be concentrated using a micro-aerodynamic lens (uADL) and collected on the walls of a micro-channel collector (uCC) where the explosive vapors will be desorbed and delivered to a detector of choice at the flow rate required by that detector. All functions: particle removal, vapor scavenging, particle concentration and collection will be implemented in a compact, modular, low-power, low-cost device. The proposed sampler can be part of an array or used as a stand-alone, possibly hand-held, unit; it can serve as the front-end for a broad range of explosives analyzers, significantly improving their sensitivity and reducing detection times.
