How Soon Will Autonomous Vehicle Fleets Take the Streets?
Automated vehicles – fleets of them – may soon change the way we travel through cities. "How soon?" asks a reader.

A new valve concept consists of a solid piston floating in a medium to control a flowstream. Although the conical shape of the seat is a prominent feature of the valve, especially when the concept was...

Variable-Camber Compliant Wing

In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in...

Resistance welding with direct current (DC) using inverter technology reduces costs by improving quality, reducing maintenance, and increasing productivity. Switching from...

Today's crop breeders are trying to boost yields while preparing plants to withstand severe weather and changing climates. To succeed, they must locate the genes for high-yielding, hardy traits in crop...

Hydraulic-Based Spherical Robot

Current spherical robots rely upon rotating mechanical weights inside the sphere to change the center of gravity of the sphere, causing the robot to roll. The use of rotating mechanical weights is not optimal due to the reliance upon moving parts, which can present burdensome maintenance issues. It would be...

Water-Based Battery Stores Solar and Wind Energy

Wind and solar energy generation creates challenges, since the Sun only shines by day, and sometimes the wind doesn't blow. Another variability is surges of demand on the grid. On a hot day when air conditioning is in use, utilities must have load-balancing strategies to meet peak demand. A...

Researchers at NASA's Marshall Space Flight Center have devised a method for the creation of crystal-free non-oxide optical fiber preforms. Non-oxide fiber optics are extensively used in...

Power Outlet Analyzes Electrical Current Usage

Electrical interruptions, or “nuisance trips,” occur when a detector installed behind the wall trips an outlet's electrical circuit when it senses something that could be an arc-fault — a potentially dangerous spark in the electric line. The problem with today's arc-fault detectors is that...

This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. To learn more about each technology, see the contact information provided for that...

Marine-grade stainless steel is valued for its performance under corrosive environments, and for its high ductility — the ability to bend without breaking under stress. But conventional...

When Navy SEALs carry out dives in Arctic waters, or when rescue teams are diving under ice-covered rivers or ponds, the survival time even in the best wetsuits is very limited — as...

Thermally Conductive Crystals Dissipate Electronics Heat

The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze, or shut down. To address this issue, researchers have optimized the crystal-growing process of boron arsenide — a material that has...

Microcontroller Altimeter (uCA)

Traditional altitude switch designs for harsh environments are mechanical in nature and operate by means of an inflatable bladder or bellows that mechanically depresses a pushbutton switch. The altitude trip point is set by mechanically adjusting the distance of the switch to the bellows. The mechanical action of...
