A system and method for allowing more rapid takeover of a failed filer by a clustered takeover partner filer in the presence of a coredump procedure (e.g. a transfer of the failed filer's working memory) is provided. To save time, the coredump is allowed to occur contemporaneously with the takeover of the failed filer's regular, active file service disks by the partner so that the takeover need not await completion of the coredump to begin.

An improved device and method for performing automatic capture/threshold determination that is particularly useful in an implantable cardiac stimulation device. While conventional devices use a fixed shortening of the AV/PV delays during automatic capture/threshold determinations, any shortening can unnecessarily cause discomfort to patients with heart blocks and unnecessarily diminish the atrial kick for other patients. Accordingly, embodiments of the present invention periodically measure the AR/PR conduction times and tabulate and/or otherwise process this data. Preferably, these measured conduction times are also correlated with the current heart rate. Finally, when an automatic capture/threshold determination occurs, this measured conduction data, which corresponds to this patient, is used to adjust the AV/PV delays while minimizing patient discomfort and adverse hemodynamic effects. Alternatively, the AV/PV delays may be manually programmable by a medical practitioner.

That is, an efficient automatic monitoring of the manufacturing environment may be accomplished with reduced probability of missing respective disturbance situations, since the large number of electrical parameters may be condensed into the predicted quality distribution.
