The present invention recognizes that traditional holiday customs or beliefs and items can be used as the basis of electronic customs. The end walls are inwardly positioned by use of an inwardly offset score design which permits the optimization of the dimensions of the tray. The network node device connects the packet-oriented network to an external device based on a point-to-point protocol and performs an address conversion of the address of a network element, said address being allocated within the packet-oriented network, into an address valid for the external device. The retainer plate is fastened to the housing body at a position axially outward from the bearing to retain the bearing in the housing body. Such processing involves fitting a function, preferably a straight line, to parameters obtained from the read signal without having to perform a differentiation step. The first graphene layer is either planar or non-planar.
