The cleanroom-compatible touch display, integrated into the stainless steel housing, shows a range of critical parameters ...

A sensor has been developed that can detect structural defects in real-time even in challenging environments such as high-temperature pipes in nuclear power plants, hazardous chemical storage tanks, ...

According to the National Safety Council (NSC), as many as 40,000 people died in motor vehicle crashes in the U.S. in 2016, the highest total in more than a decade. Among the main causes were speeding ...

WASHINGTON, June 29 -- Fingerprint sensor technology currently used in smartphones like the iPhone 6 produces a two-dimensional image of a finger's surface, which can be spoofed fairly easily with a ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...
