A piston valve assembly for a shock absorber is disclosed. These limits are superimposed on the typical gain dependent signal strength limits. The one or more ablation elements may be associated with a catheter member that slides within the catheter sheath. The method comprises determining that an errored instruction is being processed by an out-of-order execution unit of a processor and continuing to process to completion instructions earlier in-order from the errored instruction until the completion of the errored instruction. Then, the system can generate a logic data structure for the active window to describe the position of the active window in the window stack.
