NASA has patented a new technology called the Vision Chip, an implantable device that has the potential to restore or supplement visual function in a diseased or damaged retina. This technology could benefit millions of people in the US and globally who suffer from degenerative diseases of the eye’s...

This technology is an offshoot of LaRC-developed technologies using physiological measures for assessing pilot stress, sustained attention, engagement, and awareness in a laboratory flight simulation environment. The technology allows modulation of player inputs to a video game or simulation from a user interface...

The Integrated Trending and Plotting System (ITPS) is a comprehensive tool for storage, extraction, analysis, and plots of spacecraft housekeeping telemetry data (GMSEC R3.0 — Goddard Mission Services Evolution Center). ITPS reports information to...

The proposed concept uses sensors to detect high-temperature plasma ingestion during entry through a breach in the thermal protection system (TPS) caused by a micrometeoroid orbital debris (MMOD) impact. It uses consumables usually available on human-rated spacecraft such as...

Two vacuum chambers were used in tandem to perform a launch depressurization test. The test article was mounted in a 10-ft (≈3 m) Vertical Vacuum Chamber (Chamber 248-10). The 25-ft (≈7.6-m) Space Simulator (Chamber 150-25) was rough-pumped and...

This simulation environment of Contact Graph Routing that uses the QualNet network simulator leverages the previously developed space communication models. This software models the Contact Graph Routing (CGR) system proposed for future NASA missions and used in DINETl and DINET2...

In the context of systems health management, simulations serve many uses. For one, the underlying physical models can be used by model-based health management tools to develop diagnostic and prognostic models. These simulations should incorporate both nominal and faulty behavior with the ability to inject various faults into the system....

Monitoring colon health and transformation into a diseased tissue, including inflammation and cancer, is difficult using conventional techniques, as individuals are required to undergo invasive procedures. However, by using exfoliated cells, it is...

Human subjects are unsuitable for objective performance testing of victim detection radar because their heart and respiration rates are not controllable or repeatable. There are limitations on human targets from a safety standpoint as well. It is difficult to relate the ground truth to...

This invention is a process by which carbon nanotubes can be chemically functionalized according to their precise electronic structure. The process involves an exploitation of charge transfer stability at the nanotube sidewall to direct selective reaction of certain electronic structures over others....

NASA Visualization Explorer (NASA Viz) is an intuitive, interactive iOS application (app) that delivers science stories with multimedia content linking high-quality explorable images, descriptive text, visualizations, videos, and interviews with a fresh look and feel. NASA Viz aims to excite a wide audience about...

In many fields of spectroscopy, classification of the measured multivariate response is not always a straightforward process. Accurate classification is limited by many factors that are highly dependent upon the spectroscopy method being utilized. In all cases, however,...

A suite of software tools was developed that enables powerful and efficient processing of time history data. These tools can be used together or independently, offering a variety of capabilities including comparison of time history data files to validate pre-processing activities, conversion...

Cryptography and molecular biology share certain aspects and operations that allow for a set of unified principles to be applied to problems in either venue. A DNA-inspired hash code system is presented that utilizes concepts from molecular biology. It is a keyed-Hash Message...

This IRAD (Internal Research and Development) project was conceived as an aircraft instrument and designed with specifications that are closely aligned with the science requirements of the Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission. The work has been used to both advance the technology...
