The present invention is directed to electrochromic systems comprising an electrochromic glazing or insulated glazing unit, a photovoltaic module for supplying power to the electrochromic glazing or IGU, and an electronics module in communication either the electrochromic glazing andor photovoltaic module. In order to recognize and correct the drift in the amount of fuel injected over the service life of the injectors of the injection system of the internal combustion engine, multiple different corrective functions are used to establish corrected individual characteristics relative to nominal characteristics. An operator console extends from the end of the chassis opposite the wheels, with an operator platform extending beyond the base of the operator console. In yet another aspect, the remote terminal may wake up multiple times in a particular paging cycle if there are one or more candidates base station to which the remote terminal may be handed off.
