An etch resistant liner covering sidewalls of a transistor gate stack and along a portion of the substrate at a base of the transistor gate stack. The method comprises the following steps: the step of detecting the presence of an identification member in a predefined perimeter around the vehicle; the step of authenticating that the identification member is associated with the vehicle; and, in the case of positive authentication, the step of placing the access system in a \u201cready to unlock\u201d state for all the opening members. A control unit of the scanning section includes a first image acquiring section that acquires first image data by making the scanning section execute scanning at a first subscanning resolution. The resistive mechanism further comprises a biasing mechanism that urges the movable interface member into engagement with the resistive surface when a rotational velocity of the rotatable member is below a threshold velocity, and allows separation of the interface member and the resistive surface when the rotational velocity of the rotatable member is above the threshold velocity. The cervical plating system includes an interlocking mechanism that integrated into each of the plates such that any two plates may cooperatively engage through the interlocking mechanism such that a new cervical plate can be interconnected with a pre-existing plate during revision surgery without removal of the pre-existing plate.
