Sensors & Test

There exist many datasets that can be viewed as multivariate time series, such as the daily high temperature at a locality, sensor recordings in diagnostic systems and scientific data, and music and video recordings. These time series reside in large...

A simple method of controlling recording and display of imaging spectrometer data in (airborne) flight was needed. Existing commercial packages were overly complicated, and sometimes difficult to operate in a bouncing plane. The software also was required to keep up with...

A series of scripts stitch together existing open-source Python modules for the purpose of displaying, cleaning, and measuring photometric properties within public Kepler data. The intent of these tools is to provide convenience to the Kepler science community, and to increase cost efficiency for the project....

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...

The development of the self-diagnostic accelerometer (SDA) is important to both reducing the in-flight shutdowns (IFSD) rate — and hence reducing the rate at which this component failure type can put an aircraft in jeopardy — and also as a critical enabling technology for future...

Wide-temperature and extreme-environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme-environment electronics, by their inherent nature, allow...

This innovation is a tungsten-rhenium gauge that can be placed into an aft exit cone of a rocket motor. It will measure heat flux with time for the full duration of the RSRM (reusable solid rocket motor) nozzle environment with equal response time.

The magnetic sensitivity of a Ka-band isolator’s output phase is measured at 7 × 10–4 deg/G level. This high degree of precision is enabled by the sensitive phase measuring capabilities of a testbed built to mimic NASA’s Gravity Recovery and Interior Laboratory...

If selected for a NASA flight mission, the Ocean Radiometer for Carbon Assessment (ORCA) instrument will study microscopic phytoplankton, the tiny green plants that float in the upper layer of the ocean and make up the base of the marine food chain.
