Title: Method and apparatus for unique address assignment, node self-identification and topology mapping for a directed acyclic graph
Inventor: OPRESCU FLORIN
IPC: H04L29/12
Filed: 1993-12-16
Abstract: A node identification system is described for use in a computer system in which the various components of the system an interconnected via nodes on a communications bus.     Once the topology of the nodes has been resolved into an acyclic directed graph, each node may be assigned a non-predetermined unique address. Each node having a plurality of ports has an apriori assigned priority for port selection. Each child node connected to a parent is allowed to respond in the predetermined sequence depending upon the port through which it is connected to its parent Each node in the graph will announce its presence according to its location in die graph. Each receives an address incremented from the previous addresses assigned, thereby insuring uniqueness. The same mechanism may be implemented to allow each node in turn to broadcast information on the bus concerning the parameters of its local host. Likewise, additional information may be conveyed from each node concerning connections to other nodes thereby allowing a host system to generate a map of the resolved topology including any information about disabled links which may be used for redundancy purposes.

Patent CA-2157262-A1 (CA)
Inventor: STANTON ROBERT
IPC: H01R24/48
Filed: 1995-08-30
Abstract: An  improved  surge  arrestor for RF devices  includes  a bifilar conductor pair wound around a ferrite core wherein one end of each conductor is grounded.  The energy of RF signals input to the surge arrestor from an RF transmission line is transferred from the primary windings to the secondary windings through the magnetic coupling.  When an electrical transient or fault causes a surge on the input or primary side of the surge arrestor,  the core becomes  saturated,  thereby limiting the amount of energy transferred to the secondary windings and the RF device.  This effectively isolates the secondary side of the surge arrestor from the damaging surge in voltage and prevents the  secondary side from conducting the surge to electronic components within the RF device.

Patent CA-2175878-A1 (CA)
Inventor: HOLTON DAVID B
IPC: B31B17/00
Filed: 1996-05-06
Abstract: A machine for forming a variety of different sturdy, stackable three-part fiberboard containers having a depth dimension greater than their width dimension, and which are suitable for holding bags filled with liquid. The machine includes a slidable, removable mandrel which cycles between a fiberboard hopper area and a container forming compression area. Each of two side bins provides a fiberboard end panel which comes into contact with independently slidable edge picks on the mandrel. Just before the mandrel cycles forward, slidable picks or suction cups remove two fiberboard end panels from their hoppers. The end panels are then bent by the action of two folding elements. Meanwhile, a fiberboard body matt is brought into position in front of the retracted mandrel from an overhead feed unit. Adhesive material is sprayed onto selected parts of the body matt as it is placed into position in front of the mandrel. The mandrel then cycles forward, bending the body matt over into a C-shape and pushing the nowfolded end panels into close association with the middle of the body matt. A set of guides and plows bends the body matt flaps over the end panels forming sturdy corners. The compression plates loosely surround the bent fiberboard pieces in order to avoid early adhesion until the mandrel is fully extended forward bringing the fiberboard pieces into proper position. Once positioned, the compression plates collapse around the fiberboard pieces forming a finished container. The finished container is then displaced as the machine cycles back to form another container.
