Equipment utilization detector
First Claim
1. A utilization detector attachable to equipment for determining the utilization of the equipment, the utilization detector comprising:
- a motion detector which generates an output signal upon a change of its position relative to a plane;
a motion analysis circuit responsive to the output signal from the motion detector and generating at least one of (i) a sudden motion output signal in response to a sudden motion detected by the motion detector, and (ii) a slow motion output signal in response to a slow motion detected by the motion detector; and
a time accumulator responsive to at least one of the slow motion output signal and the sudden motion output signal, wherein;
the time accumulator records at least one of a production interval and a idling interval;
the production interval corresponds to a duration that the motion analysis circuit generates the at least one of the slow motion output signal and the sudden motion output signal; and
the idling interval corresponds to a duration that the motion analysis circuit withholds the slow motion output signal and the sudden motion output signal.

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.
