Abstract: An apparatus and method for the efficient generation of a wiring map of the connectivity between two sets of terminals at different locations which have established communication links between respective terminals at the two locations. A single at a first location uniquely identifies each of the terminals, by code, frequency, sequence of connection or the like, and is transmitted to a respective termimal at the second location via a respective communication link. The terminals at the second location are sampled and the presence of the transmitted signal correlated to the identity of the first terminal. The correlation may be direct, as by unique terminal identifier, or by a comparision of data bases stored by computers. First and second data bases, each relating the terminal locations to the transmitted information, respectively, are correlated to create a third data base used to generate a map of the linked terminals.

Abstract: A communication system has a first node which transmits on a data bus messages each having a preamble having a predetermined format including a message type and the message length, and a plurality of second nodes receiving messages from the data bus and including elements which can determine that the preamble in each message has the predetermined format. The preamble is particularly useful for allowing the second nodes to quickly detect messages not directed to those nodes of which the elements form a part, allowing the node to ignore the remainder of the message. This allows the individual nodes to exclude the message interpretation for detecting message directed to them, from their processing tasks thereby improving the effective processing speed of the network.

Abstract: A method for simultaneously transferring useful signals between connection points distributed between modules of an electronic assembly. Each signal is transmitted at least substantially continuously between a transmitting connection point and at least one receiving connection point. The method includes the steps of providing a double transfer line common to the assembly of modules, the double transfer line being formed by a group of physical conductors comprising a linking line with at least one linking conductor to which all the modules are connected and a connection line comprising several connection conductors connectible selectively to each of the connection points for transferring useful signals. An identification code is attributed to each connection point and to each connection conductor. Interconnection reconfiguration commands are disseminated by at least one of the modules directly to each of the modules.

Abstract: A slow-wave circuit for a TWT has periodic transverse plates extending across the axial by extending vacuum envelope. An opposed pair of apertures 24, 26 in each plate 20 couple adjacent cavities 28 between plates 20. Coupling apertures 24 in alternate plates 20 are rotated transverse to apertures 26 in the other plates to provide coupling only between adjacent cavities 28. Each plate 20 has transverse ridges 30 enclosing its axial beam aperture 22. The ridges 30 are orthogonal to the coupling apertures 24, 26 to increase beam coupling and decrease capacitance for wider bandwidth and higher impedance.

A deflection core forms a magnetic path for a magnetic flux generated from both deflection coils. An auxiliary coil is arranged at least a one position in a vertical deflection direction outside the deflection core. A horizontal deflection current is supplied to this auxiliary coil. A magnetic field, generated from the auxiliary coil, reduces an intensity of externally leaking magnetic field which radiates outside the deflection core when a horizontal deflection current is supplied to the horizontal deflection coils.
