Nonconjugated conductive polymers, which are all polymers that have a ratio of double bonds to total bonds of less than \xbd are doped with iodine to produce compositions with unexpected characteristics in this invention. The system notifies a mobile user that his portable terminal is within an area where it can be provided with local fast wireless communication service such as a hot-spot service versus using a low speed, but wide coverage wireless access network. The reference time mark indicates the beginning of the circadian chronobiological cycle and initializes a running time. A perimeter and depth of the single perforation can be configured to reduce a susceptibility of the acoustic resonator to process-induced variations in resonant frequency relative to an otherwise equivalent resonator that omits the single perforation. Said air valve is of a barrel valve type while said throttle valve is of a butterfly valve type.
