+*  will be continued after pulse, if there is still time remaining for it. Each client
+*  has own service and this service keeps track of overlapping vibrations within service.
+*  However, one client may interrupt another client's vibration and that is why there
+*  must be common place to keep track of overlapping vibrations.
