Abstract: A bulkhead fitting device configured to sealingly link a conduit and a wall traversed by the conduit. This bulkhead fitting device includes a first ring sealingly linked to the conduit, a second ring having a flat, ring-shaped sealing face configured to be pressed against a contact face of the wall or of an intermediate part linked to the wall, an elastically deformable intermediate annular portion sealingly linking the first and second rings, a holding system configured to press the sealing face against the contact face. This bulkhead fitting device guarantees an optimum seal while enabling the absorption of forces and slight relative movements between the conduit and the wall. The device also helps to limit the propagation of vibration.

Abstract: This control system takes into account the thermomechanical aspects of materials to quickly and easily determine optimal cutting conditions and to automatically control machining to preserve the integrity of the workpiece. This system includes an acquisition module configured to acquire values of a set of input parameters relating to cutting conditions and material properties of the piece, and a microprocessor configured for determining at least one operating cutting parameter representative of a cutting signal from the machining apparatus using a set of output parameters of an integrity model previously constructed during a learning phase. The integrity model connects the set of input parameters to the set of output parameters comprising specific cutting coefficients representative of the material integrity of the piece, and establishes at least one fatigue threshold of the at least one cutting operating parameter. The fatigue threshold allows control of the progress of cutting operations.

Abstract: A regular expression matching hardware implementation comprises two tightly coupled hardware engines. A regex engine performs state transitions and accepts (as matching) or rejects (as not matching) an input string. The regex engine takes also care of the logic of the operators and deals with the complexity of the state machine. A lookup engine reads characters from an input (e.g., tape, memory, network packets, or the like), and provides them to the regex engine. A preprocessing procedure transforms a regular expression into a regex state transition table and a lookup table, for use by the regex engine and lookup engine, respectively. The two hardware engines are synchronized by a global state machine. The regex engine advances the state machine, and the lookup engine reads it.

Abstract: A fire extinguisher device for aircraft has a hanger structure and a reservoir of extinguishing agent, the aforementioned reservoir being hung beneath the aforementioned hanger structure by metal fittings held by fasteners to the aforementioned hanger structure. The aforementioned extinguisher wherein the reservoir has means of suspension and the hanger structure has carriers complementary to the means of suspension, the aforementioned means of suspension and the aforementioned carriers being such that when the fasteners are withdrawn, the reservoir is in a position called the “intermediate position,” in which the metal fittings are free and the reservoir is suspended by interaction of the means of suspension and the carriers. The disclosed embodiments also relate to a method for fastening such an extinguishing device.

Abstract: A method and communication node for providing secure communications and services in a High Availability (HA) cluster. The communication node comprises an Operating System (OS) that detects an unavailability of a first service application process and switches a second service application process from the first state to the second state, the second service application being selected for taking over service currently provided from the first service application process, the first state and the second state each being associated to a set of rights in the cluster. The OS generates a private key for the second service application process based on its second state. The set of rights associated to the second state allows the OS to replace the first service application process with the second service application process for providing secure communications between the second service application and other service application processes in the HA cluster.

Abstract: Software, systems and methods are described which provide cache management capabilities. The number of cache sets to be used in each partition of the cache memory space is based on a number of cache pages in each partition and an associativity level associated with the set associative cache. The cache sets can be numbered based on the partition number, a total number of partitions and a cache page index. Cache management according to these exemplary embodiments reduces problems associated with cache trashing in multiprocessor environments sharing common data structures in set associative caches.

Abstract: Method and nodes are provided for propagating between the nodes information about processing capacity of peer nodes. Two types of signals are sent from propagating nodes towards their peer nodes. A propagating node sends first signal type at a constant rate and a second signal type at a variable rate. A ratio of the rates calculated at a peer node represents the processing capacity available a propagating node. Sequence numbers may be added to signals of the first and second type in order to assist peer nodes in detecting capacity issues.

Abstract: A fire extinguisher device for aircraft has a hanger structure (4) and a reservoir (3) of extinguishing agent, said reservoir being hung beneath said hanger structure by metal fittings (300, 301a, 301b) held by fasteners to said hanger structure. Said extinguisher is characterized in that the reservoir (3) has means of suspension (31) and the hanger structure (4) has carriers (41) complementary to the means of suspension (31), said means of suspension and said carriers being such that when the fasteners are withdrawn, the reservoir (3) is in a position called the “intermediate position,” in which the metal fittings (300, 301a, 301b) are free and the reservoir (3) is suspended by interaction of the means of suspension (31) and the carriers (41).

Abstract: Methods, a data source and a router are provided to fragment packets that are to be sent in multicast mode towards a plurality of destinations comprised in a multicast group. Each router along a path leading from the data source towards some of the destinations sends its maximum transmission unit value in an uplink direction. Each router directly connected to the data source calculates a lowest maximum transmission unit based on various maximum transmission unit values received from downstream routers. The data source receives from each of the directly connected routers a maximum transmission unit value, which is certain to be acceptable to all routers and destinations of the multicast group downstream of that directly connected router. The data source selects a lowest one of the received maximum transmission unit values and fragments data contents accordingly.

If a requested service is, e.g., banned due to regulatory policies in a geographic region associated with a particular access network, then the requested service shall be denied even if the user has a valid subscription to such requested service via another access network.

Abstract: A method for maintaining a current view of a cluster's membership comprising the steps of maintaining a list of member nodes and updating the list when a modification thereto is noticed by a first node by receiving a first update message from the first node in a second node, thereafter, sending a second update message from the second node to a third node to propagate the modification and sending to the first node a first confirm message from the second or the third node. A node member of a cluster capable of maintaining a first list of neighboring nodes, maintaining a second list of neighboring nodes sharing a current view therewith and ensuring that the first list matches the second by exchanging messages with neighboring nodes, wherein each message comprises topology information. Upon confirmation that both lists match, the node being capable of sending a confirmation message toward neighboring nodes.
