A method for curing a paint coating applied to a workpiece includes applying radiant light energy to cure the paint coating on surfaces of the workpiece within a line of sight of a radiant light energy source, and applying ambient air to the workpiece to cure the paint coating on surfaces of the workpiece not within the line of sight of the radiant light energy source. An inputoutput subsystem image is identified by an inputoutput subsystem image identifier, which is used by various programs to designate the particular inputoutput subsystem image for which an IO operation is to be performed. A visor is attached to the crown and includes a visor cover disposed over a unitary visor body. The polynomial is adjusted as necessary so that the selected ray is deflected at the extrapolated optical line to a desired target point.
