Embodiments of the invention relate to performing a scan of a memory region associated with a virtual machine. Upon release, the structure can be configured to filter flow through the vessel. The thermistor measures the inlet air temperature of the dryer and cooperates with the controller to prevent the thermostat from reaching its trip temperature and turning off the heat source. The expandable members are connected to the host structure arrayed radially around the elongate axis. The cover layer can be coextensive with the base layer and secured to the base layer by a bonding agent.
