Abstract: A utilization detector detects when equipment undergoes at least one of a sudden motion or a slowly changing motion. In response to detecting sudden or slowly changing motion of the equipment, the utilization detector causes a production hour meter to accumulate time over which such motion is occurring. In response to detecting an absence of sudden or slowly changing motion of the equipment, the utilization detector causes an idle hour meter to accumulate time over which motion is not occurring. The utilization detector includes an off delay timer for maintaining the production hour meter accumulating time for a predetermined interval after the utilization detector detects the termination of sudden or slowly changing motion. When the production hour meter is accumulating time, the idle hour meter is not accumulating time and vice versa.

Abstract: Disclosed is a utilization detector that detects when equipment undergoes at least one of a sudden motion or a slowly changing motion. In response to detecting sudden or slowly changing motion of the equipment, the utilization detector causes an hour meter or the like to accumulate time. The utilization detector includes an off delay timer for maintaining the hour meter accumulating time for a predetermined interval after the utilization detector detects the termination of sudden or slowly changing motion.
