AccelerometerNoiseRootPsdSource

public class AccelerationTriadStaticIntervalDetector
extends TriadStaticIntervalDetector<com.irurueta.units.AccelerationUnit,com.irurueta.units.Acceleration,AccelerationTriad,AccelerationTriadStaticIntervalDetector,AccelerationTriadStaticIntervalDetectorListener>
implements AccelerometerNoiseRootPsdSource

This detector is in charge of determining when a static period of acceleration measurements starts and finishes. Static periods are periods of time where the device is considered to remain static (no movement applied to it).
