Literally and practically — it is a device. It records physical movement using a three-axis accelerometer, sum-of-squares calculations. These calculations are time-stamped and churned through a simple algorithm to accumulate the readings over time, and record them at set intervals. The settings are easily modified through a terminal interface that allows you to see the data, adjust recording intervals and thresholds, calibrate the device, set the time and date, and a bunch of other diagnostic and configuration sorts of things. These are version 7.
