A method of reducing pollutants exhausted into the atmosphere from the combustion of fossil fuels. Methods of manufacturing such handles are also provided. The system also includes one or more optical paths positioned to image entire plate arrays in tilted andor untilted configurations. These cutoff frequencies and trigger thresholds are adapted to the rollover scenarios to be detected. The aqueous polymer compositions of the invention are useful as deflocculants, rheology modifiers and water retention agents for paper coating compositions. Other related embodiments are disclosed.
