An air conditioner for a vehicle having a passenger compartment has an electric-powered hot water pump in addition to a mechanical hot water pump driven by an engine mounted on the vehicle. Although the multi-path management software on an end-point device may operate independently, it may also cooperate with the local communication applications and the multi-path management software located on the access points or other network nodes to select one or more pathways for the local communication applications. The resulting single image data sets from the image analysis algorithms can then be stored. A circuit converts trimming information derived from the trimming information generation circuit to generate element selection information for selecting turn-off resistors to obtain combined resistance values from the resistor array.
