A calla lily plant particularly distinguished by yellow spathes, medium density maculation of the leaves that is visible from both sides of the leaf and produces 2 to 4 inflorescences per 3-cm tuber, is described. A riser measurement instrument module is connected adjacent a selected portion of the riser provides dynamic orientation data for the selected portion of the riser. A plurality of pulsed laser bursts of a pulsed laser beam is applied to the battery substrate, the pulsed laser bursts having sufficient power and duration to cut through the battery substrate and the overlying protective multilayer coating.
