A method for detecting unmanaged nodes within a system is described. An acoustic safing sensor is operative to sense acoustic waves of the vehicle during a vehicle crash event and provide a safing signal having a characteristic indicative of the sensed acoustic waves. Then, the register of better quality retiming, as determined by the fractional phase detector decision, is selected to provide the retimed output. A fixture is coupled to the first end of the rotator for securing the workpiece to the first end of the rotator. Layered on the top surface of the adhesive layer is an indicator layer that is in turn covered with a floodcoat layer.
