The disclosure generally relates to various methods to discover, configure, and leverage relationships in Internet of Things networks. In particular, it relates to so-called backside lithography, in which the final lens of an exposing system is positioned to project electromagnetic radiation through a first side of the transparent substrate and expose a radiation sensitive layer that overlays a second side of the transparent substrate that is opposite the first side. This facilitates the extraction of the inner nucleus from the outer portion of the roll. The pivot and the bush are associated at their ends with a plate arranged inside the sole.
