Briefs: Mechanical & Fluid Systems
Self-Lubrication Improves Standard Braking Systems

By mixing carbon fibers into polymer-based brakes, researchers designed brakes that are self-lubricating. These new and improved brakes can prevent wear-and-tear and have better frictional...

Making electric cars lighter also involves reducing the weight of the motor. One way to do that is by constructing it from fiber-reinforced polymer materials. A new cooling concept...

Briefs: Manufacturing & Prototyping
Synthesizing Renewable Oils for Use in Lubricants

Industrial machinery, agricultural equipment, transportation vessels, and home applications depend on lubricants; however, they leave a heavy environmental footprint. Common lubricants, oils,...

Growing demand for electric vehicles and more sustainable forms of transport means finding new forms of energy storage such as batteries, supercapacitors, and fuel cells. Currently, a major...

The first mass-produced electric vehicles (EVs) hit the road late in 2010 with the introduction of the Nissan Leaf, which remains the world’s top-selling,...

Facility Focus: Battelle Memorial Institute

Battelle Memorial Institute was founded in the early part of the 20th century as a charitable trust focused on research in metallurgy and allied industries. Founder Gordon Battelle studied...

Briefs: RF & Microwave Electronics
System Enables Direct Data Transmission Between Underwater and Airborne Devices

Today, underwater sensors cannot share data with those on land, as both use different wireless signals that only work in their respective mediums. Radio signals that travel through air die very rapidly in water. Acoustic signals, or sonar, sent by underwater devices...

Automotive Manufacturing - April 2019

Factories are getting smarter thanks to advances in robotics, analytics, simulation, metrology and more. To help you keep pace with the latest developments, we present this compendium of recent articles...

Question of the Week: Materials
Will Carbon Fibers Find a New Place in Vehicles?

In a Tech Briefs article last week, Virginia Tech professor Greg Liu spoke about his team’s newly developed porous carbon fibers, and how the material may someday change how vehicles are built and powered.

Application Briefs: Imaging
Driverless Forklifts

Although driverless forklifts have been around for about 30 years, it's only in the last 10 or so that they've been free to maneuver anywhere around their environment. In the early days, the machines followed a current...

Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...

Briefs: Automotive
Precision Low-Speed Motor Controller

Innovators at NASA Johnson Space Center have developed a method for controlling precise motion of a brushless DC (BLDC) motor using relatively inexpensive components. Precision motors are usually quite expensive and inefficient when operating at slow speeds. Current motors are only capable of operating at...

Future Unmanned Aerial Systems (UAS) and air taxis will require advanced onboard autonomy to operate safely within complex and dynamic urban environments. Urban landscapes...

The Create the Future Design Contest, launched in 2002 by the publishers of Tech Briefs magazine, helps stimulate and reward engineering innovation. The annual event has...

Briefs: Aerospace
Effects of Reynolds and Mach Numbers in Large Eddy Simulation of Supersonic Round Jets

Rockets/landers arrive on the Moon with supersonic speed and impact lunar regolith. There is no reliable software to computationally simulate in an effective way the supersonic plumes escaping from these rockets/devices. A Large Eddy Simulation (LES) model and...

Connected Commercial Vehicles - March 2019

Trucks and other commercial vehicles are becoming smarter and more connected, moving rapidly on the road to autonomy. To help you keep pace with the latest developments, we present this compendium...

With self-driving vehicles poised to take the road, how can today’s engineers prepare themselves to support an autonomous future?
Tesla uses batteries to store energy underneath the car seats. What if we could store energy everywhere on the vehicle?
How do you regulate a system that, in effect, is learning as it goes?

RTM370 imide resin was developed to address the limitations of conventional imide resins, which are generated from commercially available symmetrical biphenyl...

Different types of motion encountered in dynamic environments require designers to specify connectors for boards, wiring, and devices that can meet significant g-forces,...

Special Reports: Transportation
Powertrain - February 2019

The latest powertrain innovations for cars and commercial vehicles are featured in this Special Report, a compendium of recent articles from the editors of Automotive Engineering and Truck & Off-Highway...
