An apparatus for weighing a stent includes a buffer for storing a stent support with a stent mounted thereon, a stent mounting and dismounting assembly that mounts and dismounts the stent from the stent support, a robotic arm for moving the stent support with the stent between the buffer and the stent mounting and dismounting assembly, and a scale assembly for weighing the stent. The piston includes a shallow bowl extending from adjacent an edge of the piston head to an inner side slightly beyond a peak. The method further includes determining if there are any modifications in the set of data contained in the simulated data storage device after termination of the malware detection experiment. The presented application windows are visually grouped into one or more clusters, at least one cluster including a set of application windows, and at least a first of the application windows in the set of application windows visually overlaps a second application window in the set of application windows. 05 to about 50% of silicone by weight of the composition. The system includes an implantable cardiac stimulation device, including a conductive enclosure, ventricular arrhythmia termination pulse generator, and an atrial arrhythmia termination pulse generator.
