Abstract: An improvement to conventional ATM network paradigms involves the distribution of ATM switching functions across a large number of ATM switching units, each of which may typically provide a limited number of available ports, and by establishing multiple connections between the larger number of ATM switching units in a partially redundant "chained" configuration analogous to various ring type topologies. A plurality of "XNODES" each comprising a packet segmentation/reassembly circuit and an ATM switching circuit may be interconnected in various ways to form redundant ATM paths without the need to replicate large and expensive ATM switches.

Abstract: An infrared optical gas-measuring system with two infrared radiation sources (1, 2) and with at least one multispectral sensor (5). The system is suitable for determining the concentrations of different components of a gas flow. The two infrared radiation sources (1, 2) radiate in different spectral ranges with two different cycle frequencies f.sub.1, f.sub.2. The rays emitted are first passed through a radiation coupler (3), after which they pass through the gas flow to be measured, which is limited by windows (8), at right angles to the direction of flow. The rays finally enter a multispectral sensor (5), of which there is at least one, for measuring the intensity.

Abstract: A system using a public access medium to establish asymmetric full-duplex circuits connecting a premises device and a central device. The premises device converts a standard Ethernet interface into the asymmetric full-duplex link. The central device aggregates traffic from a plurality of asymmetric links into one or more local ethernet connection. The premises device is attached to any network node (such as a personal computer, LAN bridge/router, terminal server, etc.) which offers an ethernet interface. The device thereby emulates an Ethernet LAN so that the network node's operation is transparent. Such an Ethernet to asymmetric converter is provided at one end of the asymmetric full-duplex link. The central device aggregates traffic from several asymmetric links into one or more Ethernet connection. This device inspects Ethernet packets as they are transferred in order to determine which physical ports should receive a packet. This device resembles or is provided as a local area network bridge.
