Various radio frequency identification tags are described that dynamically vary their resonant frequency to reduce or eliminate the potential effects of electromagnetic \u201ctag-to-tag\u201d coupling. The support housing includes an adjustment mechanism, and the elastomer assembly includes an outer ring that encircles an elastomeric material, a central bushing embedded in the elastomeric material, and a plurality of shims embedded in the elastomeric material in a parallel planar fashion. The hot system includes a first heat exchanger configured to circulate a first vaporized stream of the working fluid from the heater in heat exchange relationship with a first condensed stream of the working fluid to heat the first condensed stream of the working fluid. An opening is formed in the internal circular area of the toroidal stator, to allow the entry and exit of the passengers of the vehicle. The counter-clockwise groove of the roller gives a second regulating force, which points toward the center position, to the magnetic tape.
