The uncertainty principle states that we cannot know the state of a system with arbitrary precision. Now the uncertainty relation between angular momentum and position has been measured in an ...

I love 3D Touch, but FingerAngle, by Carnegie Mellon spin-off Qeexo, may have just upped the ante. The researchers behind FingerAngle, a new algorithm that allows smartphones to estimate the angular ...

Engineers use rotary encoders to measure the angular position of an attached device, such as a motor shaft, or to measure distance indirectly when used with a linear belt drive, for example. Rotary ...

Several applications require a through shaft which prevents from using the basic principle which is angular position measurement using variation of magnetic field amplitude induced by the displacement ...

In every Olympic event, officials try to keep things is as fair as possible. In track, this means making sure runners cover the same distance. Short distances make this easy---simply paint a ...
