Accelerometers

Accelerometers measure linear acceleration. They can be also used for specific purposes such as inclination and vibration measurement. MEMS accelerometers embed several useful features for motion and acceleration detection, including free-fall, wakeup, single/double-tap recognition, activity/inactivity detection and 6D/4D orientation.

Accelerometer: Medical Alert Devices and other interesting

From the functionality of medical alert devices to measuring proper acceleration or g-force, one needs an accelerometer. However, this small device doesn't measure what most people think of as acceleration (an increase in speed). Instead, accelerometer's measure what scientists consider proper acceleration, or the acceleration of an object relative to inertia or free-fall.

What Is a 3-Axis Accelerometer? (with picture)

A 3-axis accelerometer is a device that is designed to measure acceleration along three axes in space — the forward and back X-axis, the left and right Y-axis, and the up and down Z-axis. Since an accelerometer measures acceleration as related to a state of free fall, where no forces are acting on it except for gravity, 3D acceleration is

Vibration : Measure Acceleration, Velocity or Displacement

Sep 05, 2011· 24 Comments. When using vibration data, especially in conjunction with modelling systems, the measured data is often needed as an acceleration, as a velocity and as a displacement. Sometimes different analysis groups require the measured signals in a different form. Clearly, it is impractical to measure all three at once even if we could.
