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 ...

Besides temperature, pH measurement is one of the most common controls used in the processing of aqueous media within various industries. One example is in chemical processing where titration is often used to drive the pH to a certain level, in order to initiate, maintain, optimize, or terminate reactions. Another instance involves the monitoring of cell growth bioreactors, where microbial and e ...

The reliability of wind turbine systems is greatly impacted by hidden defects. Therefore, an improved method of inspection is sought for the manufactured composite materials used in these systems. In addition, an inspection method is also needed in the field, to assure quality during and after installation. This project will develop a reliable, portable, instrumentation system that can be utili ...

Geologic carbon sequestration has been identified as a potential means of reducing the amount of carbon­dioxide emitted into our atmosphere, thereby reducing one of the major contributors to global warming and climate change. A major difficulty with carbon­dioxide sequestration is monitoring sequestration sites and pipelines for leakage, which may come from zones on the order of 1 meter in s ...

Electronic procedures are currently being used to document the steps in performing medical operations for the Space Shuttle and/or the International Space Station (ISS). Capturing the data electronically makes is easier to manage, modify and query the contents of the procedures. For the ISS, NASA is currently transitioning to electronic procedures based on the eXtensible Markup Language (XML) stan ...

NASA captures and distributes operational knowledge in the form of procedures. These procedures are created and accessed by a range of people performing many different jobs. These people have different needs for procedure data and different ways of interacting with procedures. We propose an Procedure Integrated Development Environment which will present different editing modes and different views ...

Determining the probability of specific medical events on a given space mission is difficult. Yet, it is important to have reasonable estimates of these probabilities in order to make informed decisions about managing the associated risks. NASA's mission is and always will be to push the envelope, to go where no historical record exists to give guidance. Consequently, it is necessary to conside ...
