A medical assembly includes an implant and an envelope at least partially enclosing a portion of the implant. The truck comprises an arm mechanism for lifting a recycling container from a baseline, a self-dumping hopper for holding the recycling materials, and an on-board module controlling a movement of the arm mechanism. The memory jumping operation may jump locations within the file corresponding to a predetermined memory jumping operation timeframe, and in order to account for the variability in the recording bit rate and therefore the playing of the instance of content, the jump locations in the memory jumping operation may be dynamically adjusted based on recording bit rates. Thereby, even when the responsiveness of the variable valve timing controller is varied due to an increase in the fuel diluting quantity, it can be avoided that the computer determines that the variable valve timing controller has a defect.
