Researchers at NASA’s Marshall Space Flight Center have developed a system that reduces the entrapment risks associated with a pool or spa’s recirculation drain. The technology prevents hazards caused by suction forces on the body, hair, clothing, or other articles. Employing a novel configuration of...

The demands for high-sensitivity and high-resolution radiometry have recently led the science community to examine the use of large deployable mesh reflectors, which have heretofore only been used in telecommunications applications.

The Intermediate Palomar Transient Factory (iPTF) is a visible-spectrum astronomy survey aimed at detecting “transient” events such as supernovae. Every night, a telescope at the Palomar observatory collects images of various regions of the sky and compares them to a set of reference...

This application serves as Web-based management of the Systems Engi - neering Education and Development (SEED) program, and enables the SEED Program Manager to track and manage the applications and assignments. In the past, the handling of the applications and assignments was...

NASA’s Langley Research Center has developed new software that enables users of critical inspection systems to validate the capability of the inspection system. Traditionally, inspection systems are validated using various methodologies to...

Lithium-ion (Li-ion) cells are increasingly used in high-voltage and high-capacity modules. The Li-ion chemistry has the highest energy density of all rechargeable battery chemistries, but associated with that energy is the issue of catastrophic thermal runaway with a fire. With...

The X-Plane Connect Toolbox is an open-source research tool used to interact with the commercial flight simulator software X-Plane. XPC allows users to control aircraft and receive real-time state information from aircraft simulated in X-Plane using functions written in C, C++, Java, MathWorks’ MATLAB, or...

NASA’s Langley Research Center has developed a synthetic 3D visualization flight display that presents flight data information in an intuitive way using 3D computer graphic capabilities. The flight crew can preview and...

NASA’s Langley Research Center has developed a technology at the forefront of a new generation of computer and video game environments that trains valuable mental skills, beyond eye-hand coordination, for the personal improvement, not just the diversion, of the user.

This work was conducted to create a means of simulating and visualizing the behavior of a self-stabilizing distributed clock synchronization protocol developed at LaRC (Langley Research Center). The protocol has many applications including projects that directly...

The focus of this research was the design, optimization, and measurement of a monotonically profiled, smooth-walled scalar feedhorn with a diffraction-limited ~14° FWHM (full width at half maximum). It is an easier-to-manufacture, smooth-walled feed that...

There is an association between High-Intensity Long-Duration Continuous AE (HILDCAA) activity intervals and the acceleration of relativistic >1 MeV electrons in the magnetosphere. All of the HILDCAAs that occurred in solar cycle 23 (SC23) from 1995 to 2008 led to the acceleration of...

libSPRITE is a set of software libraries used in the development of software applications. The libraries provide components for encoding engineering units, math functions, a task scheduler built on top of pthreads, a publish/subscribe data distribution system, and a Lua scripting language interface.

The Space Station Research Explorer provides current information on International Space Station (ISS) experiments, facilities, and research results through video, photos, interactive media, and in-depth descriptions on iOS and Android devices.

The objective of this innovation was to develop a methodology of fabricating thermopile detectors using standard semiconductor fabrication techniques. The goal was to develop a fabrication process that minimized the roughening of the Si legs during patterning of the metallic couples, and to...

Experiments that take into account the impact of convective weather on airspace operations, future concepts, and flight deck tools require a source of weather data that is readily available, of predictable quality, and tailorable to experimental objectives. Real-world weather data is sparse, highly random, and disorganized....

The software package BALFIT was developed for both the processing of wind tunnel strain-gage balance data and the analysis of more general multivariate experimental data sets. The software uses automatically generated regression models for the analysis....
