A delay locked loop circuit that includes a delay line having a plurality of delay elements. A first position includes a standby position wherein the enclosure and the damper arrangement block access to the interior volume. A second telescope has a third sightline substantially parallel to one of the first and second sightlines. A pair of minors is coupled to the frame. Moreover, the method preferably includes switching back to the first one of the proactive and reactive route discovery and the associated processes when predicted route stability reaches a second transition parameter. In one embodiment, a method involves determining a steady state average torque and a torque during acceleration or deceleration of the vehicle traveling over an underlying surface.
