This NIST Phase 1 SBIR effort will demonstrate the feasibility of low noise single photon up conversion using KTiOPO4 (KTP) or LiNbO3 (LN) or Stoichiometric LiTaO3 (SLT) periodically poled waveguides and an 1800nm pump for a high efficiency single photon detector. The key innovation is using low noise periodically poled waveguides with a long wavelength (1800nm) pump leading to higher efficiency s ...

This SBIR deals with developing a commercial AC Resistance-Ratio Bridge based on research work done by R. D. Cutkosky at NIST during the 1980's. His initial work will be extended by this Phase 1 project to allow for a new state-of-the-art product design and development. The product, the Model 8686 Precision Resistance-Ratio Bridge, will have an operating current range from 0.1mA to 10mA user selec ...

This project researches, develops, and demonstrates the technical merit and feasibility of awearable device which (1) detects the direction of a sound source or motion, and (2) alerts the user viavibration, images, and captions to the direction of this sound source or movement relative to the currentposition of the individual. This provides the user with a sense of independence and personal safety ...

Existing cognitive performance test batteries consist of synthetic tasks that, while they may probe isolated cognitive functions, provide an incomplete and unconvincing picture of an individual's true cognitive capacity within the total context of space missions. In essence, they are 'laboratory' measures that appear unrelated to the real-world environment. This leads to user non-compliance or re ...

NASA aerocapture missions require an accurate evaluation of radiative thermal transport in order to simulate the aerothermal environment around space vehicles. However, present day computation of radiative transport in this complex multi-dimensional environment is frequently done using simple one-dimensional tangent-slab approximations or optically-thick approximations which compromise the accura ...

The purity of hydrogen fuel is important in engine testing at SSC. The hydrogen may become contaminated with nitrogen, argon, or oxygen. The hydrogen from the fuel tanks or feed lines is analyzed beforehand. Therefore, there is a need for a non-intrusive, on-line, near real-time monitor for H2. The analytical technique should measure various impurities (molecular and atomic) simultaneously and be ...

Most science educators agree that inquiry based learning is an important part of science education. As such, this project is developing the Electronic Chemistry Laboratory Workbook with tactile controls and interface hardware that can be used to carry out experimental simulations. ECLW will be an integrated learning tool that offers a realistic hands on feeling for simulated lab experiments includ ...

The ability to store large amounts of cryogenic fluids for long durations has a profound effect on the success of many future space programs using these fluids for propellants, reactants, and life support systems. The high cost of delivering payload mass to orbit will require storage systems capable of limiting cryogenic losses due to boil-off to less than two percent per year for mission duratio ...

Innovative approaches for broadband multi-function antennas that conserve vehicle weight and reduce drag are welcome solutions for all airborne platforms including suborbital vehicles, where less total weight translates to longer mission times, less expensive payloads, and more acrobatic flight control. The Spectra Research team proposes an innovative approach to accomplishing the program objectiv ...

This SBIR technology transfer program offers the opportunity to produce a new generation of advanced large area and monolithic pryoelectric detector arrays that fully exploit the benefits of domain engineering and "smart-cut" technologies. SRICO will Investigate domain-engineering patterns to reduce acoustic noise as well as techniques to optimize a thin film absorber to enhance the detector absor ...
