Portable, optical brain imaging for concussion was evaluated by researchers at the University of Pittsburgh Schools of the Health Sciences. They say this is the first step toward demonstrating its use on patients.

This method mitigates the motion blur introduced when a display, and/or the operator reading it, is undergoing vibration (e.g. during the launch phase of spaceflight). If both the operator and the display are undergoing vibration, their respective impulses need not be in phase. This mitigation...

Image processing techniques for determining dust optical density in Apollo videos have been developed. The software generates histograms, and calculates the mean and standard deviation, which are then used to match dusty and clear images for the purpose of estimating an effective optical...

Safe spacecraft landing on planetary and small body surfaces is of primary concern. Estimation of landing risk is a critical task when evaluating and certifying potential landing sites. Such analyses require the detection and mapping of all potential landing hazards such as rocks and boulders, craters,...

A new JPL project requires that the center of the images of a rising or setting Sun be determined with certain accuracy — for example, within 1 km — when the Sun is observed from the International Space Station (ISS). This center-finding technique...

This report presents the design, construction, and test results of a novel multitone, multi-band, high-frequency synthesizer for application in a space-borne (including a CubeSat) beacon transmitter for radio wave atmospheric...

Most of today’s automotive electronic systems are composed of two major mechanical elements: an equipment chassis or enclosure, and a printed circuit board (PCB) assembly. The PCB is composed of laminated copper and FR-4 glass epoxy. These systems often operate in severe...

The Arduino platform was used to develop an interface between two otherwise incompatible commercial devices in order to drive the ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer) rover over long distances. The Portable Operations Terminal consists of three distinct parts: a robot-mounted...

A quick and cost-effective evaluation/screening technique for new battery chemistries was developed that integrates the individual advanced cell component in a full-cell format to identify the critical issues, such as cell component interaction and compatibility before proceeding...

Recently, one-dimensional (1-D) nanostructures, such as nanowires and nanotubes, have become the focal point of research in nanotechnology due to their fascinating properties. These properties are intrinsically associated with low dimensionality and small diameters, which may lead to...
