In this NASA Phase I STTR effort, the feasibility of fabricating isolated ridge waveguides in 5% magnesium-doped lithium niobate (5% MgO:LN) will be established. Ridge waveguides in MgO:LN will significantly improve the power handling and conversion efficiency, increase photonic component integration, and be well suited to space based applications. The key innovation in this effort is to combine ...

This SBIR Phase I effort proposes to establish the feasibility of developing a compact, high performance laser source for integration into the next generation seed laser system for high stability, multi-wavelength lidar applications such as NASA Langley's HSRL program. Combination of the high performance laser source together with ADVR's integrated Planar Lightwave Circuit (PLC) technology will p ...

This Small Business Innovation Research Phase I project will develop a compact, rugged, rapidly and widely tunable laser based on a quantum cascade diode laser at mid-infrared wavelengths. The key innovation in this effort is the use of an engineered electro-optic tuning element in an external cavity laser to provide control of the laser wavelength through an applied voltage. AdvR has previously ...

The overall goal of this multi-phase project is the development of a system that will help individuals orient themselves and safely navigate in vocational environments. The system will also be designed to assist individuals in finding and identifying items and objects. Various strategies and technologies have been introduced to provide navigation assistance, including devices that support audio ...

The three primary drive systems for power wheelchairs-front, middle and rear wheel drives-have a wide range of advantages and disadvantages. Users select the drive system based on their individual needs. Currently, no power wheelchair has a variable position drive system that the power wheelchair user can automatically move fore/aft through a range that will provide the benefits of rear, middle ...

The proposed innovative insulation would greatly enhance the usability of, and reduce the inherent losses associated with, cryogenic fuel delivery and storage apparatus. The proposed insulation has been tested to yield a thermal conductivity value of 0.019w/mK @ one inch format @ an areal density

A recent breakthrough in combustion stability analysis (UCDS) offers the means to accurately predict the combustion stability of a scramjet. This capability is very important due to the extreme scramjet operational environment, which makes cut-and-try development approaches impractical. With UCDS, it is now possible to accurately predict the scramjet pressure oscillation amplitudes, along with c ...

In recent years, there has been a tendency to use ever-higher gas turbine inlet temperatures, resulting in ever-higher heat loads necessitating efficient cooling. Internal cooling designs have evolved from the use of simple curved ducts in early designs to very complex geometries. Similar complexities govern film cooling as well, leading to complex fluid-structure interactions and turbulence physi ...

Focusing on a reduced-dimension problem of a hypersonic orbital/lunar reentry capsule, an algorithm will be built which combines the stochastic Monte Carlo method for treatment of radiation transport in optically thin to moderate domains, with a single-term modified differential approximation (MP1) for use in optically thick domains. This numerical method will be verified against a known benchmar ...

The proposed innovation is a "Microfluidic Multichannel Flow Cytometer." Several novel concepts are integrated to produce the final design, which is compatible with on-orbit operation from the standpoint of gravity-independence, low mass, low power requirement and automated operation. The unique design features of the Microfluidic Multichannel Flow Cytometer include compact optics based on diode ...
