An electrode on a semiconductor substrate includes a polysilicon layer, a silicon-implanted layer on the polysilicon layer, a tungsten nitride layer on the silicon-implanted layer, a tungsten nitride layer on the silicon-implanted layer, and a tungsten layer on the tungsten nitride layer. A corresponding relation is established between the privilege authentication and the identity authentication so that the privilege management can be performed accurately and reliably. At least one of the first data port and a second data port deactivate electronic circuitry of at least one of the first and second data ports upon detection of the lack of data. The automotive wiring harness comprises the wire bundle. Monitoring of environmental conditions and facility operations of the facility, also in substantially real time and time correlated with the energy monitoring, is performed to further enhance the management and reporting of the energy performance of the facility. In addition, the detected engine speed is smoothed and a gain for determining the convergence speed of the adaptive controller is determined appropriately.
