Disclosed is an electronic system for use on vehicles. More specifically, the present invention provides a unified data analysis and processing scheme to break down and review entity profile data. The task of building a geometric model begins by establishing a set of entities that are of interest in the environment. The reference voltage is used as a reference voltage for voltage generating circuits 11-31. The energy source for the evaporation of the combustion gas andor oxidant is the heat generated by the coil temperature of an electric motor used to transport the gas.
