A system in a moving surveillance vehicle operates in background mode to capture images of license plates of neighboring moving vehicles, which may occupy lanes other than the lane in which the surveillance vehicle is moving. The power plane includes a region to which a power voltage is applied and a region to which a ground voltage is applied. A first conductor located on the die surface connects to each component of the first set. The transimpedance amplifier has a transimpedance that is a function of temperature and process that is substantially the inverse of the function of temperature and fabrication process of the transconductance of the input transistor. signal C for sensing tractortrailer coupling, and processor means 28 operable to pass the signal C after a predetermined time delay TC, if said signal is stable, and which is also operable to maintain said stable signal C if the signal is interrupted for less than a predetermined time interval tc. Further, a compression seal shutoff valve will be secured during rough-in to the water outlet pipe within the box interior.
