Abstract: A non-volatile memory disposed within electrically powered medical equipment is described. The non-volatile memory may be preprogrammed to store utilization limits and parametric data for the equipment. An external control module may be programmed to store the utilization history for the equipment in the non-volatile memory on an on-going basis. The control module compares the utilization limits and utilization history during each use, and disables the equipment if a utilization limit is exceeded. The control module may also use the parametric data stored in the non-volatile memory to regulate the power supplied to the equipment.
