Data Acquisition

This software provides the processing for a non-contact system that remotely estimates the heart rate and respiration rate of individuals as they carry on daily activities, and also enables detection of heart and respiration rate through walls.

Functional connections within the brain can be revealed through functional magnetic resonance imaging (fMRI), which shows simultaneous activations of blood flow in the brain during response tests. However, fMRI specialists currently do not have a tool for visualizing the complex data that comes from fMRI scans....

Viewpoints software allows interactive visualization of multi-variate data using a variety of standard techniques. The software is built exclusively from high-performance, cross-platform, open-source, standards-compliant languages, libraries, and components. The techniques included are:

When adapting GPS sensor technology from an aviation environment to a space environment, the search window for a satellite’s frequency and code phase is greatly increased. This problem is also magnified when multiple antennas are used. A new algorithm...

Insulation systems usually do not operate on their own; they must work together with a structural system that is designed to support the article being insulated. Typically this structure penetrates the insulation, degrading it in some manner, and gives a pathway for...

Large axial load forces and extreme temperature ranges are typical for scientific balloon missions. Therefore, a durable, flexible, and thermally stable sensor material is needed. In this innovation, sensors have been designed to be integrated onto...

A miniature, low-power, solid-state detector for ionizing radiation was developed for use in more locations, and requiring less space and lower power than current technology. An accepted way of counting high-energy charged particles common in space radiation is to detect the light...

The UAVSAR (Uninhabited Aerial Vehicle Synthetic Aperture Radar) ground data processing infrastructure facilitates a wide range of mission operational processes through a centralized database, Web-enabled interfaces, and background automation. By...

The guarded flat plate insulation test cryostat (Cryostat-500) is a boil-off calorimeter comprising a flat-bottom test apparatus for measuring the absolute thermal performance of an insulation test article. Typical dimensions allow accepting test specimens 200 mm in diameter by up to 30 mm thick. The test...

The Inductive Monitoring System (IMS) software tool uses data mining techniques to automatically characterize nominal system operation by analyzing archived system data. These nominal characterizations are then used to perform near-real-time system health monitoring or to analyze...

The determination of local geodetic parameters for VLBI (very-long-baseline interferometry) antennas is traditionally done by conventional surveying techniques. These techniques are laborious and error-prone. The objective here was to develop a space geodesy method of measuring the parameters to make it easy to...

When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either incomplete information, is telling only part of the truth, or is fabricating a false answer, or a combination of all three. When the person is habitually making...

Knowledge of a patient’s cardiac age, or “heart age,” could prove useful to both patients and physicians for encouraging lifestyle changes that are potentially beneficial for cardiovascular health. This may be particularly true for patients who exhibit symptoms, but who test negative for cardiac...

A new program has been written that utilizes advanced numerical methods to perform high-precision, sub-pixel volume measurements of samples that are processed containerlessly. The volume measurements are essential for the measurement of density and thermal...

Lunar Mapper (LM) is a Web-based software that allows visualization of lunar spatial data layers acquired from lunar missions and other sources. The data includes imagery, digital elevation models, resource maps, and model output. LM is accessed using standard Web browsers and uses open-source tools and libraries. The data is stored on...

Software has been developed that provides an integrated and automated test environment for the Space Telecommunications Radio System (STRS). This software package is Linux based and provides interactive and scripted control to test the JPL Software Defined Radio (SDR)...
