Abstract: Described herein is coated article comprising: (a) a substrate comprising a ceramic, a glass, or a glass ceramic, wherein the substrate comprises a surface, the surface comprising a continuous upper portion and a plurality of lower portions, wherein each lower portion is connected to the upper portion by at least one sidewall; and (b) a first layer comprising a material capable of physical vapor deposition, wherein the first layer is disposed on the continuous upper portion and at least a portion of each sidewall and wherein at least a portion of each lower portion is free of the first layer. Methods of making such coated articles are described herein, wherein the substrate is coating via angular physical vapor deposition.

Abstract: A local area network which is multi-path in nature and uses many small programmed nodes interconnected by low bandwidth cables with a typical data transfer rate of 9600 BPS. Connections between pairs of devices on the network are obtained by a flooding technique at the start of communications which is performed by a network control program resident in each node. Data transmitted between devices connected to the network is packetized and routed through the network via the nodes identified by the flooding operation. Packet transmission through node output ports is buffered and multiplexed so as to reduce degradation in response time by heavy traffic monopolizing a node output port.
