Sigma-K Corporation proposes to develop a Hermetic Textile Closure Hardware System to be used for Chemical Biological (CB) protective clothing and Collective Protection (COLPRO) portable shelter systems. Our Hermetic Textile Closure Hardware System design will allow the user to easily don and doff… More

We at Sigma-K Corporation will develop an angular valve displacement measurement system that will meet the Phase II measurement specification requirements during the course of the Phase I Work Plan. These specifications will include the following (1)measurement of the angular displacement of a… More

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… More

Carbon Nanotubes have great potential of adding strength in composite materials. In order for carbon nanotubes to be used in prepregging, fibers with diameters in the 7-10 micron range are needed. The carbon nanotubes need to be bundled and twisted to form appropriate size fiber tows. Current… More

Currently, there are over 10,000 MRI scanners used in the US alone. US citizens today are mobile and many times medical treatments may require MRI scans from several different facilities. Images from MRI scanners can also drift over time. There is a tremendous need for all medical imaging scanners… More

Magnetic Resonance Imaging data needs to be calibrated using a universal standard. NIST and the ISMRM SQRM committee have developed the NIST/NIST MR phantom. The group had two phantoms manufactured to their specifications and these phantoms have been imaged at numerous imaging facilities. Sigma-K… More
