A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a display unit including a touch screen; and a controller configured to enter the touch screen into a locked state, to display a lock screen and an application program icon for executing an application program on the lock screen when entering the locked state. The method comprises: measuring a successive approximation register conversion time; comparing the successive approximation register conversion time with a desired conversion time; and if necessary, performing a closed loop adjustment of at least one of the supply andor comparator common mode voltage. The accessory support may comprise part of the interior rearview mirror assembly or may include a mirror mounting element with the interior rearview mirror assembly adapted for mounting to the mirror mounting element of the accessory support. Further, a second conductive contact is located over the front surface and is electrically connected to the second conductive structure. When the wedge is moved yet axially further relative to the transition member, the driveshaft tube is further deformed in a controlled and consistent, thereby absorbing energy from the collision.
