Offshore wind is an enormous potential resource for the United States - with strong, consistent winds located in the Atlantic, Pacific, the Great Lakes, and the Gulf of Mexico. As part of a planned six-year $180 million initiative, an initial $20 million will be available from the DOE this year as the first...

Each year, upwards of 1.5 million cases of traumatic brain injury (TBI) occur in the United States. Conventional imaging methods don't always provide physicians with as much detail as they would like when it comes to determining how the injury damaged the patient's brain tissue, predicting how the...

An impact model was developed to predict how three specific foam types would damage the Space Shuttle Orbiter insulating tiles. The inputs needed for the model are the foam type, the foam mass, the foam impact velocity, the foam impact incident angle, the type being impacted, and whether the tile is new or aged (has flown...

This document discusses a technique that provides a means for suspending large, awkward loads, instrument packages, components, and machinery in a stable, controlled, and precise manner. In the baseplate of the test machine, a pattern of grooves and...

A document describes a zeptobolometer for ultrasensitive, long-wavelength sensors. GSFC is developing pixels based on the zeptobolometer design that sense three THz wavelengths simultaneously.

A document describes a high-performance, modular, and state-of-the-art Command and Data Handling (C&DH) system developed for use on the Lunar Reconnaissance Orbiter (LRO) mission. This system implements a complete hardware C&DH subsystem in a single...

A document discusses an electro-optic sensor that consists of a collimator, attached to one segment, and a quad diode, attached to an adjacent segment. Relative segment-segment motion causes the beam from the collimator to move across the quad diode, thus generating a...

An inorganic, biodegradable silica gel fiber (SGF) acts as a physical scaffold to aid the growth of new cells and the collagen structure that supports them. As a scaffold, it can also be used to deliver drugs over a wide area to aid in healing. The material is integrated into the tissues and...

Energy-saving nozzles offer droplet sizes down to 25 microns, at operating pressures as low as 100 psi. Nozzle passages, including metering slots, spin chambers, and exit orifices, are designed to minimize pressure drop, resulting in conservation of pump energy up to the exit orifice.

A company wants to decrease the frequency and severity of respiratory illness in homes with adults, teens, and children. Affordable indoor air quality improvement solutions must be provided to consumers via an air purification device. The client seeks a third-party partner who can offer a currently commercialized/...

Many types of food spoilage are slowed when air and moisture are removed from around the food. Current removal solutions, however, are expensive, take up too much space, and require complicated processes. A new technology must remove air and moisture with the single push of a button. Any proposed...

Specialized mixed-signal (radio frequency and digital) hardware and processing techniques are employed to enable processing of the multi-GHz signal bandwidth, along with the instruction of an inter-symbol guard time (ISGT) to facilitate synchronization to the received pulse-position modulation (PPM) signal.

The Laser Interferometry Space Antenna’s (LISAs) scientific mission to detect gravity waves demands stringent noise limits on the system components, especially the large-area quad photoreceiver front end, for ultra-high-precision (≈10 pm/Hz1/2) distance...

Wavefront sensing is a process by which optical system errors are deduced from the aberrations in the image of an ideal source. The method has been used successfully in near-normal incidence, but not for grazing incidence systems. This innovation highlights the ability to examine...

RxGen is a prescription generator for JPL’s in-house optical modeling software package called MACOS (Modeling and Analysis for Controlled Optical Systems), which is an expert optical analysis software package focusing on modeling optics on dynamic structures, deformable optics, and controlled...
