A zero emissions fuel system includes a fuel tank fluidly interconnected with a fuel vapor containment and absorption canister. The inner reference curve is preferably selected such that it lies in the vicinity of the neutral colors. The precise values of the components in the RLC circuit are selected according to the attenuation and distortion characteristics of the coaxial cable connecting the drive electronics assembly from the imager assembly. The temperature sensor conducts a load current that heats-up the temperature sensor when a first temperature threshold is crossed and a supply potential is in being supplied.
