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 ...

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 ...

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 ...

We propose an alternative to using Microsoft Word for representing medical procedures that will make the procedures easier to construct and maintain, particularly when there are changes to the hardware or changes to the resulting format of the procedure. We call this alternative an "electronic procedure". Rather than a text-based document, this content-based document separates the text from the fo ...

Piezoelectric motors operate on the principal of high frequency oscillation of high force precision ceramic elements. The high power oscillations are converted to rotary motion through a novel conversion mechanism to produce high torque precision motion when compared with traditional electromagnetic motors. Dynamic Structures and Materials (DSM) proposes to focus the Phase I innovation on the de ...

The majority of students and educators would probably agree that students are better able to grasp scientific concepts from the use of hands-on activities and other inquiry-based educational practices than from typical lecture problem solving methods. Anasphere, Inc is working to make inquiry based tools and materials for weather and climate education more readily available for students and educat ...

TO INTERPRET, EVALUATE, AND ANALYZE DATA FROM REMOTE-SENSING, MULTISPECTRAL INSTRUMENTATION IN REAL OR NEAR-REAL TIME IS THE GOAL OF THIS PROJECT. THIS SYSTEM WILL BE ADAPTIVE BY LEARNING TO INTERPRET APPLICATION-SPECIFIC FEATURES. BASED ON NEURAL-NETWORK TECHNOLOGY, IT WILL FOCUS ON PATTERNS FOUND IN THE DATA REGARDLESS OF THE IRRELEVANT VARIATIONS OF INTENSITY, MAGNIFICATION, CLUTTER, OR NOISE. ...
