Multi-colored electronic displays that are dynamically reconfigurable require substantial electrical power and are limited in the amount of fine detail provided by the physical size of the light sources. For example, where phosphor elements are used, as in a television screen or computer monitor, the...

Fluid flow systems often require orifices to control pressure drop or flow rate. These orifices are often retained in bolted housings that require seals and introduce potential leak points into the system.

A hybrid mechanical/electrostatic force actuator has been developed for use in deformable mirror applications. Some deformable mirrors, designed to correct errors in optical systems, use electrostatic forces between the flexible mirror surface and a backplane to control the shape of...

Multiple Spacecraft Per Antenna (MSPA) techniques have been used for well over a decade to increase the efficient utilization of ground network assets while decreasing the antenna fees allocated to the missions. In the Deep Space Network’s traditional MSPA service, two missions...

This invention relates to the devices and methods for the measurement and/or for the specification of the perceptual intensity of a visual image, or the perceptual distance between a pair of images. Grayscale test and reference images are processed to produce test and reference luminance images. A luminance filter function...

A modified oxidation catalyst material can be used to build a carbon-monoxide-sensing electrode for amperometric sensors to overcome the typical cross-sensitivity of these sensors toward hydrogen. The technology will have applications in the emerging hydrogen fuel cell economy...

The NASA Experiment Designer (NED) is a client-server application that enables end-to-end support for driving long-running scientific computer simulations such as climate and weather models. The tool provides a friendly, single point of entry for configuring parameters associated...

This software was designed to automate delivery of tasking requests to a central queue, enabling integrated observation scenarios across multiple assets. It is a JAVA code application that enables machine-to-machine access between a client platform and the Campaign Manager application program interface (API) to...

The Simple Subset Wizard (SSW) was developed for the Earth Observing System Data and Information System (EOSDIS) to simplify the myriad ways of ordering or obtaining subsets of satellite data from EOSDIS’ different data centers. It provides a simple, coherent interface to a variety of subsetters at ten of the centers. The SSW...

This library provides an abstraction layer that an end user can access, interpolate, and perform fieldline integration for space weather simulation data. Normally, accessing and interpolating space weather simulation data requires knowledge of...

Lossless data compression has been employed in space to reduce communication bandwidth requirements for onboard storage for more than 15 years. A widely used space compression standard is the recommendation published by the Consultative Committee on Space Data Systems (CCSDS). The standard describes a simple,...

This software implements the protocols described in the Consultative Committee for Space Data Systems (CCSDS) publication CCSDS 735.1-B-1. The purpose of the protocols is to enable the exchange of messages among a group of applications. The protocols provide several mechanisms for message...

Advanced remote-sensing instruments in recent years often employ multiple wavelengths for maximal science return. Many of them comprise hundreds to over a thousand spectral bands. These instruments multiply the data volume and stress the communication bandwidth. With previously deployed space...

This innovation consists of the Traffic Aware Strategic Aircrew Request (TASAR) concept and the associated Traffic Aware Planner (TAP) software. TASAR is intended to enable pilots to discover trajectory improvement opportunities while en route that will result in...

Module::Build::Database was developed as part of the Atmospheric Composition Processing System, which works with the Science Investigator-Led Processing System for the Ozone Monitoring Instrument. The technology allows the user to distribute changes to the schema in a database alongside software that relies on the database.

Different types of information are used to help aircraft maintain separation standards. At the lowest level, information is needed to indicate if separation standards will be violated in the near future, called a conflict. Once a conflict is detected, then conflict resolution information may be used...

A data-dependent algorithm was developed for estimating symbol signal-to-noise ratio (SNR) with a non-integral number of samples per symbol. The classical split symbol SNR estimator algorithm was adapted to incorporate the whole symbol by removing the data polarity.

A document discusses a puncture self-healing polymer for space exploration that is capable of puncture healing upon impact. Puncture healing occurs instantaneously, providing mechanical property retention in lightweight structures.

A paper describes a process for imposing safety constraints on a spacecraft trajectory design. The conventional process has the ACS (Attitude Control System) team define geometric constraints, then the NAV (Navigation) team produces a compliant thrust direction...

A document describes a design optimization method for determining optimal shapes for vehicles with mid-range lift-to-drag ratios that are entering or re-entering planetary atmospheres. The design space includes consideration of hypersonic aerothermodynamic properties (for minimizing heating)...
