The present invention relates to a processing system and to pieces of software for one or more communication networks. The carrier block includes an inclined side and a carrier side. In a first embodiment, the rendering process produces a minimally enclosing bounding box surrounding all rendered objects. The closure unit moreover includes a hood attached onto the connection body for receipt of a head of a person lying with the body in the body receiving space. An offset anchoring system for use with the mooring system is also disclosed. Moreover, the internal impedance may be implemented using a passive component, an active component or both.
