On inspecting a glass substrate for a mask blank which substrate has surfaces including one end face, the glass substrate is prepared to have the one end face which has a chamfered surface and a remaining surface serving as a side surface. The first polymeric container includes a first continuous body portion and a first rim having a first surface. Network condition includes such factors as continuity of wiring, connector status, connected devices, topology, signal delays, latencies, and routing patterns. In a second mode of switching the distribution is changed according to a media-time coding mechanism in which typically data is being transmitted simultaneously across more than one of the multiple diverse medium. Flow records may be shared from the primary security system with the secondary security system.
