With a steady rise in fuel prices and increasing restrictions on emissions, automakers face difficult challenges as they are forced to find ways of making their cars lighter and more fuel-efficient. One way to achieve this goal is to incorporate strong, lightweight, and durable composite materials to replace...

When NASA launches the Ice, Cloud and land Elevation Satellite-2, or ICESat-2, in 2017, it will measure Earth’s elevation by sending out pulses of green laser light and timing how long it takes individual photons to bounce off Earth’s surface and return. The number and patterns of...

A new discovery will make it possible to create pixels just a few hundred nanometers across. The "nano-pixels" could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such as 'smart' glasses, synthetic retinas, and foldable screens.Oxford University...

Researchers at MIT and Cornell University will provide photographers with squadrons of small, light-equipped autonomous robots that automatically assume the right positions for photographic lighting. With the new system, the photographer indicates the direction from which the rim light should...

Graduate students from the University of Colorado Boulder are designing robots to work in a deep-space habitat, tending gardens and growing food for astronaut explorers.The team's entry in the eXploration HABitat (X-Hab) Academic Innovation Challenge is called "Plants Anywhere: Plants Growing in Free...

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...

The goal of this work was to model lunar surface systems using a declarative planning system (ASPEN — Activity Scheduling/Planning Environment), provide a parameterizable Excel document to aid in the model generation, and deliver both Mac and PC versions. An adaptation of Microsoft Excel and...

“Portable Distributed Scripts” (PoDS) is a Python application that allows users to execute serial independent tasks concurrently across nodes on multicore clusters. The package consists of a set of scripts working together through a simple text-based interface. A user only needs to provide minimal information...

In order to demodulate an optical PPM signal, the receiver must align its slot clock to that of the received waveform to count the number of arrivals within each slot. The large bandwidth expansion factor of PPM, M/log2(M) requires a prohibitively large sample rate when a fixed sample clock N times greater than...

The detection of distant objects in an image is relevant to applications in defense, security, and robotics. Successfully detecting objects of interest has been a common problem with respect to intelligent computer vision. Automatic target recognition (ATR) systems have been formulated and...

DBD Innovations Iontophoresis is a well-researched technique for delivering medicines and cosmetic agents through the skin. Current techniques, however, are inefficient, and existing devices are often expensive, bulky, and awkward. A Dielectric Barrier Discharge Iontophoresis (DBDI) solution enhances...

Researchers from North Carolina State University and the University of Eastern Finland have developed new “sensing skin” technology designed to serve as an early warning system for concrete structures, allowing authorities to respond quickly to damage in everything from nuclear facilities to...

Researchers from the USC Viterbi School of Engineering have developed a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with other thin film transistors. The hybrid could take the place of silicon as the traditional transistor material used in...

Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.
