Melt-Film Fibrillation (MFF) technology produces a facing for acoustic batts for vehicle sound insulation that offers equivalent or superior sound-deadening performance at reduced weight and cost. Equivalent weights of MFF fibers produce substantially enhanced sound insulation over...

This dual-membrane technology provides apparel with a high degree of comfort, passing air and water vapor easily. The garment (or survival enclosure) can instantly be made impervious with the flip of a switch on the belt-mounted power pack. The garment can be toggled between high comfort and high...

A company seeks a sensor that is sensitive and quantitative for ethane from 5 ppm to 5,000 ppm, and for methane from 5 ppm to 7,000 ppm. The sensor(s) should work in or near oil. While the location of the sensor heads should primarily be positioned in the headspace above the oil, ability to...

A firm seeks to identify spectral filter technologies to operate within a demanding optical environment. The technology solution will enable the suppression of out-of-band wavelengths above 100 nm, while exhibiting minimal loss to wavelengths of the order of 10 nm. The solution can be manufactured...

Wind and Temperature Spectrometry (WATS) is a new approach to measure the full wind vector, temperature, and relative densities of major neutral species in the Earth’s thermosphere. The method uses an energy-angle spectrometer moving through the tenuous upper atmosphere...

Health Manager can detect “Bad Health” prior to a failure occurring by periodically monitoring the application software by looking for code corruption errors, and sanity-checking each critical data value prior to use. A processor’s memory can fail and corrupt the software,...

This software provides a programming interface for automating data collection with a PhaseCam interferometer from 4D Technology, and distributing the image-processing algorithm across a cluster of general-purpose computers.

Oscillation or instability is a situation that must be avoided for reliable hybrid DC/DC converters. A real-time electronics measurement technique was developed to detect catastrophic oscillations at early stages for hybrid DC/DC converters. It is capable of identifying low-level...

Work was conducted to validate the use of the rover external flexible coaxial cabling for space under the extreme environments to be encountered during the Mars Science Laboratory (MSL) mission. The antennas must survive all ground operations plus the nominal 670-Martian-day mission that includes summer and winter...

High Q resonators are a critical component of stable, low-noise communication systems, radar, and precise timing applications such as atomic clocks. In electronic resonators based on Si integrated circuits, resistive losses increase as a result of the continued...

A technique has been devised to enable creation of a dynamic set of test points in an embedded digital electronic system. As a result, electronics contained in an application specific circuit [e.g., gate array, field programmable gate array (FPGA)] can be internally “probed,” even when...

The ultracapacitor-based uninterrupted power supply (UPS) system enhances system reliability; reduces life-of-system, maintenance, and downtime costs; and greatly reduces environmental impact when compared to conventional UPS energy storage systems. This design provides power when required and...

This software provides capabilities for autonomous cross-cueing and coordinated observations between multiple orbital and landed assets. Previous work has been done in re-tasking a single Earth orbiter or a Mars rover in response to that craft detecting a science event. This...

This software is an improvement on Version 2, which was described in “EOS MLS Level 1B Data Processing, Version 2.2,” NASA Tech Briefs, Vol. 33, No. 5 (May 2009), p. 34. It accepts the EOS MLS Level 0 science/engineering data, and the EOS Aura spacecraft ephemeris/attitude data, and produces...
