Abstract: In local data distribution network configuration a plurality of bidirectional data distribution busses 110 are each connected to a bus master control circuit 129 at a terminal end of the bus. Connected to each of the data distribution busses are a plurality of passive outlets 161 to which intelligent connectors or stations 160 may be connected. Each station has a unique address and is utilized for individually coupling data processing devices 120 to the bus. Grouped pluralities of the bus master control circuits are included within a bus termination hub facility 130. Data from any of the bus master control circuits may be transferred by the bus termination hub via a data trunk 111 as part of a star type configuration, to a central switching circuit 150 such as a virtual circuit switch. Direction of data flow on each of the bidirectional busses and periodic temporary synchronization of the stations is controlled in response to signals transmitted to the bus by the bus master control circuitry associated with that bus. A bus termination hub switching facility cooperates with the included group of bus master control circuits to interconnect data processing stations on the various busses with the virtual circuit switch via the trunk line and with each other. 
     The bus termination hub facility further includes bus monitoring, status polling and maintenance facilities. A faulty bus will be disconnected if a fault is discovered during monitoring intervals. It will remain disconnected until the fault is corrected.

Abstract: In a twin spool gas turbine engine the electronic engine control modulates the open area of the compressor bleed valves during engine transients as a function of a ratio of the actual rate of change of the compressor speed to a maximum scheduled rate of change such that the bleeds are opened more as the actual rate of change approaches the scheduled maximum rate. This continuous modulation provides smooth thrust transition from one steady state condition to another while maintaining a proper safety margin relative to the engine surge line.
