Q&A: Catching Up with Automotive Cybersecurity Researcher (and Jeep Hacker) Chris Valasek

Once only fantasy, autonomous vehicles are becoming reality thanks to advances in laser technology and photodetection. However, fully autonomous vehicles require an array of sensory systems to provide information about the vehicle’s surroundings. LiDAR is one of the leading systems for empowering...

Regulators and consumers demand increasingly lower levels of harmful volatile emissions in motor vehicle passenger cabins, pushing manufacturers toward more comprehensive testing – from component level to finished vehicles – to ensure conformance and avoid costly tear-out. This...

A Tech Briefs TV video demonstrates NASA’s rotary-wing “air taxi” concept. The vehicles, in theory, have the capacity for vertical take-off and landing, eliminating the need for long runways.

NASA hopes the air taxi will support Urban Air Mobility, a system that combines onboard/ground-piloted...

In the race to make the most efficient electric vehicle, the design of power electronics converters plays a vital role. Power losses, breakdown voltage, switching times, and thermal conductivity of semiconductor devices are critical factors when designing power electronics converters.

When it comes to reliable RF/Microwave signal transmission, the military aerospace industry has reached a MISSION CRITICAL juncture where the specification requirements no longer meet the demands and increase in technology to ensure a system’s functionality is...

An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases.

This 60-minute Webinar on energy harvesting is part of the Technical Webinar Series from the editors of Tech Briefs Media. Three experts will look at the latest technologies related to this important subject area.

MIT has built the first-ever plane with no moving parts. Instead of turbine blades, propellers, and fans, the aircraft relies on an “ionic wind” — a silent but strong flow of ions, produced onboard, which generates enough thrust to propel the plane over a sustained, steady flight.

“This has...

Professor Shahsavari and graduate student Sung Hoon have demonstrated a process for producing a cement that is stronger, lighter, and more durable than the traditional Portland cement.

Glenn's revolutionary Shape Memory Alloy Rock Splitters (SMARS) device is fabricated from nickel-titanium-halfnium (NiTiHf), nickel-titanium-zirconium compositions, or a combination. These compositions contain a secondary, nanometer-sized precipitate phase that is produced through processes of...

Conventional night vision goggles all use image intensification (I2) tube technology that multiplies ambient, visible, and near-infrared light several thousands of times, allowing a user to see and operate in very-low-light conditions. One shortcoming of I2 tube night vision devices is that they...

One significant area of research in fuel cell technology includes systems in which a fuel cell is combined with another power generation device (a turbine, for example) to create a hybrid system that combines the advantages of the two standalone systems, resulting in a high fuel-to-electricity...

A real-time ion mobility sensor developed to detect contaminants and explosives is reliable, sensitive, robust, and inexpensive. The technology improves sensitivity and reduces false alarms for threat agents, and can identify chemicals with a sensitivity of five parts per billion.
