Embodiments may provide an exhaust gas management arrangement for an engine. Additionally including an output memory comprising a multiplicity of output queues, wherein each of the output queues in output memory is associated with one of the queues in said local memory, and a burst writer which writes N descriptors simultaneously from the mini-queue in the local memory to its associated output queue in output memory. Further, the control section calculates, based on the current values detected by the semiconductor relays, load electric power consumption of the loads, and estimated electric power consumption of the loads when the semiconductor relays are continuously ON, and allows a display section to display, as a value indicative of an energy-saving effect, an electric power amount difference i. In another embodiment, the invention is a dimensionally stable and growth controlled inflatable member comprising longitudinal zones of crosslinked material symmetrically spaced about the circumference of the inflatable member and a uniform working diameter. Registration geometry may be added and positioned to further allow interface with weapon geometry and prevent rotation of the fitting during use.
