Subsampling of data is performed at a high subsampling rate in an image sensing device such as a CCD. The mobile device uses a first timer and a second timer to monitor its internal operations. A second intake valve controls air flow from a second intake port to the piston cylinder, where the second intake valve has a second lift profile different than the first lift profile. The controller rotates the display unit to a third position where the display surface is oriented toward a front passenger seat, when an occupant is seated solely in the front passenger seat. A modified executable binary code for the runtime application is then generated by replacing the function code for the function with the corresponding modified function code. Afterwards, the data recorded in the register is programmed back to the second cell when the program verifying operation performed on the second cell fails.
