The acceleration sensor (13) transmits the acceleration change information acquired to the acceleration processing module (12) for processing.

In use, the alarm is triggered by the controller when the acceleration change is larger than a preset acceleration threshold.

was therefore not subject to rate of change of acceleration.

It was therefore not subject to rate of change of acceleration.

The change of acceleration of user's hips during the exercise is measured by an activity meter (6).

If the change in acceleration is less than the inactivity threshold and, if a predetermined period of time has elapsed, then inactivity is detected.

So, Williams contended that before the trend in the price changes, the direction of momentum will change and that even before this, there will be an acceleration change in momentum.

The desired change in acceleration is computed based on the error signal (34) and a gain factor that is proportional to a desired response time of the control system.
