Award Data

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 ...

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 ...

A nonhazardous urine pretreatment system prototype is proposed that will stabilize urine against biological growth or chemical instabilities without using hazardous chemicals. Untreated urine fosters biological growth, ammonia off-gassing, creation of bio-solids, and inorganic precipitates, which foul water and air reclamation hardware. The current Russian system employs hexavalent chromium, a s ...

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 ...

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 ...

SETI proposes to develop GaN and Si based multicolor FIR/THz cameras with detector elements and readout, signal processing electronics integrated on a single chip. The active detector elements will be submicron gated channels with 2 dimensional electron gas (2DEG). The devices with gated 2DEG (commonly known as field-effect transistors) respond to the incoming FIR radiation due to the rectificat ...

The Innovation Laboratory, Inc. builds a control system which controls the topology of an air traffic flow network and the network flow properties which enables Air Traffic Management (ATM) to adapt to hazardous weather constraints and provide high capacity flows in the National Airspace System (NAS). The Network Flow Organizer automatically adjusts the flows of air traffic with respect to weather ...

Effective methods are needed to control pervasive Lunar Dust within spacecraft and surface habitations. Once inside, airborne transmission is the primary mode of dispersion. Inhalation of this fine powder may pose a serious health risk. Lunar dust may cause degradation of materials, interfere with proper operation of instrumentation & controls, and may prevent formation of adequate seals. To solv ...
