In the planetary skew rolling blooms to form seamless metal tubing or pipe the internal tool is retracted at the leading andor trailing end of the tubular bloom to allow the rolls to seal the end or ends and prevent coolant from entering the rolled tubing or bloom. In this approach, a light source generates a probe beam which is directed to the sample. Other embodiments of the module are provided along with related methods and components thereof. An optimization algorithm determines the level of protection which should be assigned to each element in each slot, subject to transmission bandwidth constraints. An upshift point represents a second engine speed at which the gearbox effects an upshift.
