An engine ECU calculates a rotational variation based on a required rotation time when a complete misfire occurs in a cylinder, a required rotation time when complete combustion occurs in the cylinder, and a required rotation time during the current combustion stroke, and integrates the calculated rotational variation. When new program information is detected, a CN value is observed. A nucleic acid sequence encoding p27 protein is disclosed, as well as a method for producing p27 in cultured cells. Narrowing of the conductive elastomer overmold allows ground tracksrunners to be used on a substrate which are narrower in width than the shield frame width thereby providing increased area for component placement. Parameter other than brightness may also or instead be used.
