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.

Abstract: Systems, methods and apparatus are provided through which the presence of a portable detector in a parking mechanism of mobile digital radiography system is used to change the operating mode of the portable detector and a mobile X-Ray system. An existing mobile digital X-Ray imaging system may be retrofitted with parking sensor mechanism for determining the proximity of the portable detector to the mobile digital radiography system. Also provided is a method for controlling a mobile digital imaging system having a mobile X-Ray base and having a parking mechanism for holding a detachable detector. Upon detecting the presence of the detachable detector in the parking mechanism a control signal is generated to alter the speed of the mobile unit and the power consumption status of the detachable detector.
