Water-Repellent Nanotextures Possess Anti-Fogging Capability
Some insect bodies have evolved the ability to repel water and oil, adhere to different surfaces, and eliminate light reflections. Scientists have been studying the physical mechanisms underlying these properties found in nature and mimicking them to design materials for use in everyday...
Briefs: Transportation
Polymer membrane separators play a crucial function in many energy and water technologies including energy storage, hydrogen generation through water electrolysis, and...
Briefs: Transportation
Technological advancements in materials, sensors, and computing have driven demand for higher-performance satellites. Satellites need to be much more capable in a much smaller size with a longer...
Briefs: Imaging
A driverless car is making its way through a winding neighborhood street, about to make a sharp turn onto a road where a child’s ball has just rolled. Although no person in the car can see that ball, the car...
Briefs: Motion Control
Technology was developed that not only allows wheels to “know” when and how to rotate, but also enables them to work together in interactive teams. The new technology can be used wherever there is a need for...
Briefs: Propulsion
Innovators at NASA’s Glenn Research Center have developed a simple, lightweight, inline, two-speed drive that can be used either as an overall transmission, or as a supplemental add-on input...
Briefs: Transportation
Power electronics used for routing, control, and conversion of electrical power traditionally utilize silicon semiconductors. These systems tend to be bulky, require active cooling, and are inadequate for...

Automated Announcements of Approaching Emergency Vehicles
Street intersections that are equipped with traffic lights would also be equipped with means for generating audible announcements of approaching emergency vehicles, according to a proposal. The means to generate the announcements would be implemented in the intersection-based subsystems of...
Briefs: Electronics & Computers
The purpose of this article is to describe, in more detail, the transponder installed in each vehicle that participates in the emergency traffic-light-preemption system described in the...
Briefs: Electronics & Computers
Strobe-enhanced traffic signals have been developed to aid in the preemption of road intersections for emergency vehicles. The strobe-enhanced traffic signals can be incorporated into...
Briefs: Electronics & Computers
Two electronic communication-and- control systems have been proposed as means of modifying the switching of traffic lights to give priority to emergency vehicles. Both...
