A positive displacement piston unit is provided that utilizes a magnetorheological or electrorheological fluid as the transmission fluid. Typically, three or four RBE values at three or four corresponding spacially-dispersed intervals along the beam line are calculated. The controller module determines whether an emergency service is ongoing and initiates a detachment request message of the non-emergency service to the service network via the cellular station, only when no emergency service is ongoing. These interconnect materials include doped polysilicon, polycides, and tungsten metal.
