Abstract
A cordless machine operation detector including a vibration sensor, a location detector, a data logger, and a transceiver. The vibration sensor detects when a machine is operating by sensing the vibrations that are caused by the machine during operation. The location detector provides a geographical location and includes a time clock for providing time. The data logger uses time from the time clock and an operation indication from the vibration sensor for logging the time for operation of the machine. The data logger also logs a geographical location associated with the machine operation. The transceiver communicates the times and locations of the operation of the machine through an interchange to a tracking monitor. The machine operation detector, the interchange, or the tracking monitor includes an engine time monitor and an alarm sensor. The engine time monitor tracks an accumulated time of operation of the machine. The alarm sensor provides alarms when pre-defined limits of engine time or location are exceeded.
