ABSTRACT:
Systems, processes and apparatus are described through which signals are received from a controller, where the signals include a power ON signal. A time measurement element is started responsive to the power ON signal to assess a current duration of operation of the system. An existing cumulative record of system operation is recalled from a non-volatile memory in the system and the existing cumulative record is combined with the current duration to provide a representation of a running elapsed time, which is recorded in the non-volatile memory and is compared to a threshold to provide an indication when the running elapsed time has traversed the threshold.
