When an operation of a fuel cell system is stopped, a flow of cathode off-gas into a circulation passage is stopped. An energy reduction device receives high voltage electrical power from a utility. A signal is exchanged between the line termination equipment and attached network termination equipment, passing through the crosstalk canceller which acts as a multiline simulator. The discharge tube has mercury and metal halides enclosed therein. The systems are analyzed using one or more anonymous proxy accounts. Controller determines an object time interval corresponding to the time the object is within the danger zone and when the source vehicle time interval corresponds with the target vehicle time interval.
