A Computer based on a dual processing structure, with a main processing subsystem associated to an alternate processing subsystem. Each machine unit has a work spindle which is supported displaceably in the axial direction of the spindle in a carrier of crankshaft-like design. When a vehicle is within a specified distance of an automatic fueling service terminal, known as the zone of proximity detection, the vehicle identification code and service terminal identification code are both continuously determined and passed to a multi-port station controller, for authentication of service transactions and secure service processes, including automatically fueling the vehicle. In a truly distributed realization, adjacent receiving nodes or base stations exchange soft complex signal information with each other, thus forming at least partially overlapping groups for distributed collection of information, detection and subsequent decoding in each base station. The amplifier assembly further optionally includes an out-of-band second stage LNA. The plating system includes instrumentation and method for installation thereof.
