InnovaTek proposes to develop an advanced, low cost aerosol collector/concentrator that utilizes electrostatic precipitation and cyclonic impingement with a virtual impactor pre-concentrator that will have >90% collection efficiency while operating at 1000 LPM using less than 50 watts of power. Technology will be designed on the basis of first principles and computational fluid dynamics modeling. Components will be fabricated using 3-dimensional CAD drawings based on models and calculations. During Phase I several mini-collector prototypes will be designed and fabricated to test our theories and establish feasibility of the scaled-up system. Variables to be examined include electric field intensity, central electrode diameter, deposition cylinder diameter and length, cyclone inlet size, and liquid impingement methodology. System efficiency will be determined using aerosolized particles and microorganisms. Power requirements and ease of manufacturing will also be considered. Final component geometries and operating parameters will be selected on the basis of performance and estimated manufacturing costs. At the end of Phase I a scaled-up design, to be fabricated and tested during Phase II will be delivered.

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. This device will be fabricated in silicon using micro-fabrication methods resulting in 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 the fluid flow and particle trajectories inside aerodynamic lenses. We will fabricate lenses on silicon wafers using standard wafer micro-fabrication methods, and we will test the performance of those lenses using carefully prepared aerosols. Finally, we will make detailed comparisons between the predictions of our CFD models and the experimental results. At the end of phase I, we will have developed a reliable CFD modeling capability that can be used in phase II to design more complex structures and we will have demonstrated the feasibility of fabricating these lenses in silicon using standard micro-machining techniques. We will also have developed a battery of diagnostic methods to assess the performance of these devices which will be used in phase II to assess the performance of 2-dimensional arrays of aerodynamic lens aerosol concentrators.

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 two proposed air sampling technologies to be developed are amenable to dry or nearly dry sample collection, but yet both can deliver a final sample in an aqueous format autonomously. Furthermore, both offer 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. The technologies to be developed by the proposed effort will result in samplers that can be integrated with a broad range of advanced biodetection technologies including mass spectrometry, microchip arrays, PCR and immunoassays.

A compact, low power and low cost air sampler is proposed that utilizes a novel topology and two-stage design to concentrate respirable particulates. The proposed hardware and collection strategy minimizes problems associated with freezing conditions and provides a high air-to-liquid concentration ratio.

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.

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.

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 is presented to produce very low cost Basic B AIS transponders. The result will be a very small, minimal cost product with a maximum of functionsality that can be easily installed in a few minutes. Because of its very low power consumption, it is also suitable for handheld, portable and solar powered use.

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.
