A method includes the steps of producing hydrogen gas and a hydrocarbon fuel, blending the hydrogen gas and the hydrocarbon fuel into the hydrogen enriched fuel, using the hydrogen enriched fuel in the engine, and tracking emissions during the producing step and during the using step. Furthermore, when such photo image isare displayed at monitor, such image data is converted to monitor color space image data through color matching using working ICC profile and monitor ICC profile. The physical layer data field value is associated with the physical transmission of packets from the RF component.
