Air-Lock, Incorporated proposes to design an Enhanced Shoulder Mobility Joint Assembly (ESMJA) that increases dynamic mobility and static sizing capabilities for spacesuited crewmembers (CM) employing a Hard Upper Torso (HUT). The proposed shoulder joint will allow historically fixed Hard Upper Torsos to be sized in-situ by crewmembers of varying anthropometries. The Shoulders will also increase ...

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 lead-lag motions of rotor blades in a helicopter require damping to stabilize them. In practice, this has necessitated the use of external hydraulic dampers which suffer from a high maintenance cost. This high operational cost has prompted the rotorcraft industry to use elastomeric lead-lag dampers that result in ``dry'' rotors. However, complex behavior of elastomers provides challenges for t ...

In a rotorcraft, optimized camber change not only reduces vibratory hub loads and noise but also increases available thrust and improved flight control augmentation. Therefore, the ability to dynamically change airfoil camber is a significant technology advancement leading to improved overall rotorcraft performance. Research efforts in recent years have led to the application of active material ac ...

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 ...

The recent advances in data collection and storage capabilities have led to information overload in many applications, including on-line monitoring of spacecraft operations with time series data. Such datasets present new challenges in data analysis, especially for implementation in memory-constrained DECUs. Also, the traditional statistical methods break down partly because of the increase in th ...

This project develops a social networking system that: (1) brings real world skills andsettings into the home and school using video modeling, (2) is safe and cost effective, and (3) creates atrusted network for parent and professional resource sharing.

Classroom teachers need formative assessment tools that give them easy and accurate information on student perfomance. Large scale assessments provide accountability data useful in evaluating progress across states and within school districts, but are not designed to directly impact classroom practice. Research shows us that student performance on standardized test can be impacted by test anxiet ...

Non-incremental improvements are necessary in lithium-ion batteries order to meet future space applications demands such as NASA's call for lithium-ion battery cathodes with specific capacity values exceeding 240mAh/g at C/2 discharge rate and 25ºC. Novel concepts for lithium-ion battery chemistry and/or design are therefore desired. Yardney Technical Products, Inc. proposes a development of an a ...
