We barely notice them, but they're one of the most important features buried in the everyday smartphone experience. Accelerometers are devices that can measure acceleration (the rate of change in ...

Quantifying the vibration of industrial machinery and using that information for condition monitoring (CM) has long been an ambitious goal, but also one with significant technical and implementation ...
