Many believe the greatest threat to our troops and homeland security are attacks using biological weapons. Recent developments of biological warfare agents parallel advances in microbiology, viruses and bacteria can be rendered more lethal through genetic engineering, and many toxins can be mass-produced. However, detecting biological agents is difficult and time consuming because there are thousa ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...

This Small Business Innovation Research (SBIR) Phase II project will build a first-release Web-based system for content authoring and delivery that supports multiple approaches to pedagogical practice and provides efficient, easy to use methodologies with which course designers can employ system capabilities. Specifically, this project will continue the work started and demonstrated to be feasibl ...

This Small Business Innovation Research (SBIR) Phase II project will fabricate a prototype betavoltaic battery in a form factor the size of a quarter coin. The goal will be to generate approximately 100 microwatts of electrical power in a volume less than half a cubic centimeter from a tritiated energy source. Research conducted for the Phase I portion of this project established the feasibility o ...

This Small Business Innovation Research (SBIR) Phase II project will investigate applications of Combinatorial Morse Theory in Reverse Engineering, a field that focuses on converting physical objects into a digital representation suitable for CAD, CAM, and CAE. The biggest challenge in this field is to automate the conversion process while producing a model that meets all the requirements of downs ...

This Small Business Innovation Research Phase II project will optimize Performance and demonstrate reliability of temperature insensitive silica-based arrayed waveguide grating (AWG) multiplexers developed under SBIR Phase I award. In Phase I we have successfully demonstrated that the temperature sensitivity of silica-based AWGs can be eliminated by a combination of a reflective device with a uniq ...

This Small Business Innovation Research (SBIR) Phase II project will result in a novel question-answering technology. The features of this technology are as follows: (1) Automatic filtering of questions. During Phase I, Language Computer Corporation (LCC) developed a system that decomposes high-level questions into low-level, fact-seeking questions. Some of these questions, however, turn out t ...

This Small Business Innovation Research Phase II Project proposes to develop a commercially viable monolithic Wavelength Division Multiplexed (WDM) two-wavelength Grating-Outcoupled Surface-Emitting semiconductor (GSE) laser emitting near 1310 nm. Phase I demonstrated the concept of WDM GSE lasers in a cross-grating configuration emitting two wavelengths separated by 9 nm from a common two-dim ...

This Small Business Innovation Research (SBIR) Phase II project will create a Dynamic Tactile Display (DTD) prototype with the look, feel, and functionality of the real-world product, and it will demonstrate that the DTD makes it easier to learn and use computers than existing screen reader technology. An in-home trial study will allow a group of users to have the DTD over an extended period of ...

This Small Business Innovation Research (SBIR) Phase II project integrates the imaging system developed in Phase I with a smart-sensor injection system that can inject or sample from the cavity underlying the early chicken embryo with high levels of accuracy accompanied with improved hatch when compared to manual methods. The Phase I work showed that it was possible to image and detect the blasto ...
