An exhaust brake has a body with a passageway for exhaust gases therein. An actuatable adjustment element is arranged in an alignment section. The first, conductive material forms a continuous conductive path extending along the entire length of the hose. Whether phase noise is reduced sufficiently is determined on the basis of detection results by an amplitude detection circuit for detecting the amplitude of an AC component of the composite control command signal and the lock detection circuits. Methods are provided for operation of the CMM Arm with Exoskeleton. Timing recovery parameter generating circuits are also disclosed.
