The GHz-rate phase-stabilized fiber-laser frequency comb system is proposed to be used as a light source for coherent Fourier transform spectroscopy. The system will be developed based on our proprietary glass/fiber technology, which features a low-cost, robust, highly stable, mid-infrared light source that enables the development of a robust portable c-FTIR spectrometer for absorption measurement ...

We propose to develop a commercially adequate, robust and perfomant OWL-based Integrity Constraint (IC) validation system with several innovations, including novel debugging and explanation support for data integrity errors; incremental and optimized validation of data integrity; and a unified system for validating structured, semi-structured, and semantic data. A rigorous and formal specification ...

This is an SBIR Phase II proposal to develop a tactile refreshable computer display prototype (TRCD) that will support multiple tactile alphabets (e.g. ELIA, braille, and Roman), multiple lines of text, and graphics to benefit the more than 1.8 million blind Americans. Commercially available TRCDs are expensive (~$12,000, or $19 per actuator), provide only one line of text (with 640 actuators) and ...

Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort laser pulses and optical fibers. These light sources have high brightness and are spatially coherent. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated. SC wavelength ranges are constrained by the transmission and dispersion properties of the fibers. Previously, ou ...

Southwest Sciences¿ Phase 2 SBIR project will lead to development of residential fire sensing systems based on recently developed, low cost temperature and optical imaging sensors combined with newly introduced highly miniaturized, micropower CO sensors. Sensor modules will be part of a low power wireless network. Each module will be about ½ the size of a business card, a few mm thick, and w ...

A low-cost superconducting transition edge sensor (TES) microcalorimeter spectrometer is described for high energy and high spatial resolution X-ray energy dispersive spectroscopy and microanalysis. The proposed microcalorimeter instrument offers an energy resolution that is comparable to and potentially even better than wavelength dispersive spectrometers, thereby enabling the resolution of inter ...

A key factor of international efforts to identify and suppress the supply of and demand for nuclear materials, and thereby to deter potential traffickers, is the ability to accurately identify contradicted material and ultimately to trace it back to its origin. Alpha particle spectroscopy is widely used in nuclear forensics to assay trace quantities of sensitive nuclear materials, but the limited ...

The technical objective of this project is to develop a prototype of a face recognition application in a cloud computing environment utilizing MBARK as the middleware. The application will have a client piece that will run on a mobile device such as a laptop and a server piece that will run on a higher-performance computing cluster. The specific objectives of this development project can be enumer ...

Sepax Technologies, Inc. has identified a new type of anoin-exchange resin which separates single-wall carbon nanotubes (SWCNTs) with >80% recovery yield and resolves in a single pass the chiral tubes of (6,5) well from commercial SWCNT starting materials by Chromatography. Improvement and scale up of the targeted resin production will facilitate the separation of chiral nanotubes for the academic ...

X-ray fluorescence spectroscopy is a widely used and extremely sensitive analytical technique for qualitative and quantitative chemical analysis. Superconducting Transition Edge Sensor (TES) microcalorimeter detectors have now been developed that achieve an energy resolution of 2 eV for 1.5 keV X-rays, which is sufficient to enable the measurement of the small shift of the X-ray line position that ...
