This Phase 1 SBIR project aims to develop a frequency stabilized laser diode system suitable for application in optical metrology and in displacement measurement. The compact design of the semiconductor laser lends itself to many applications where a coherent light source is required, but space is at a premium. Some fields, such as precision optical metrology require a coherent light source whose ...

There is a need for a simple, portable, quantitative method to monitor the presence of Harmful Algal Blooms. Electrochemical detection offers some advantages for analysis, but traditional sensors are not practical for routine field use. Adapting colorimetric immunoassays on porous, flow-through electrodes can provide a means for rapid, low-cost, portable quantitative environmental analysis. Thi ...

A DNA sequencer for biometric applications will be developed. The system will enable rapid and low-cost identification of individuals and kinship verification using a self-contained and portable device. All process steps from DNA extraction to DNA sequencing will be automatically performed within the disposable single-use cartridge. This high-level of functional integration is made possible by Adv ...

The recent emergence of the Silicon Drift detector (SDD), for use in energy dispersive x-ray spectrometry (EDS), has made possible x-ray event streams with count rates as high as 1-10 Mcps. A problem with existing digital signal processing, as applied to SDDs, is the significant presence of coincidence peaks above the x-ray background. These coincidence peaks occur with amplitudes comparable to lo ...

First responders operate in challenging acoustic environments where noise, alarms, engines, radio communications, and communications to others in the environment make voice communications with hands-free, voice operated switch (VOX) operation difficult. Broad Digital will use a combination of passive acoustic design, noise suppression and subtraction, signal separation, and equalization to provide ...

The vertical water vapor profile into the atmosphere is measured around the world using balloon-borne radiosondes that take measurements twice a day when the balloons are launched. The objective of this proposal is to establish the feasibility of measuring the amount of water vapor vertically, in the atmosphere as a function of altitude using a Light Detection and Ranging (lidar) operating in the ...

Role-based workflow (RBW) is a NIST invention that used RBAC technology to implement workflow, with the goal of making workflow easier to maintain and more secure. At this time, Virtual Global has completed a Phase I SBIR effort, in which computer software was created to automate the invention in the form of web services. The Phase I effort was successful in proving the feasibility of the inventio ...
