Abstract: Fluids such as air, liquid or gaseous fuels are stored within a passage of a helically wound flexible hose sandwiched within a peripheral portion of a tubular enclosure of a transport vehicle between an outer shell and an inner support layer of such tubular enclosure, within which equipment and personnel are transported through an environment such as seawater, atmospheric aerospace or outer space. The foregoing structural arrangement provides for highly efficient performance of fluid storing tankage and vehicle envelope support functions.

Abstract: A long term average and a short term value of the strength of a received signal is used to determine a trigger condition in a mobile communications system to perform such functions as control channel or traffic channel reselect. The long term average removes the effects of short term fades in the short term signal that otherwise may cause a premature trigger decision. The short term value offsets historical bias that may be built into long term average. The actual trigger is only realized when both the long term average and the short term value exceed predetermined thresholds in a positive or negative direction.
