Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...

Apple is looking to add Apple AR technology to the Measure app on iPhone, making it more accurate and automatically annotating objects with their measurements. The Measure app on iPhone became useful, ...

U-tube: the glass tube and piezoelectric speaker that were used to create the new mass sensor. (Courtesy: William Grover) A $12 device that can measure the mass of microgram-sized objects in fluid has ...

The ISL29501 overcomes the shortcomings of traditional amplitude-based proximity sensors and other ToF solutions that perform poorly in lighting conditions above 2,000 lux, or cannot provide distance ...

With the introduction of ARKit in iOS 11, Apple put a stake in the ground in the mobile Augmented Reality race. Some of the best early AR apps used your phone to measure linear distances—a digital ...
