20110120427 | TWIN TURBO ASSEMBLY AND METHOD FOR OPERATING A TWIN TURBO ASSEMBLY - A twin turbo assembly is provided for an automotive vehicle that includes, but is not limited to a first air intake for sucking in ambient air, a first turbo charger that includes, but is not limited to a first compressor connected to the first air intake, a first intake duct connecting the first turbo charger to a combustion engine, a second air intake for sucking in ambient air, a second turbo charger that includes, but is not limited to a second compressor connected to the second air intake, and a second intake duct connecting the second turbo charger to the combustion engine. The first intake duct is connected to the second intake duct, and a first bypass valve is provided to connect the first air intake to the first intake duct bypassing the first compressor and/or a second bypass valve is provided to connect the second air intake to the second intake duct bypassing the second compressor. Due to the bypass valve, an overpressure inside the intake ducts can be discharged to a volume between the air filter and the respective compressor. The released pressure prevents or at least reduces the risk that compressed air inside the intake ducts may flow against compressing direction of the first compressor and/or the second compressor, so that the noise emission associated with this backflow is reduced or even prevented. | 05-26-2011 |

20080201403 | Maintaning a View of a Cluster's Membership - 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. | 08-21-2008 |
20090106436 | METHODS AND SYSTEMS FOR OFFLOAD PROCESSING - Communication nodes, systems and methods are described which provide offload processing capabilities. Tasks can be offloaded from a host element to an offload processing element. Incoming data streams can have their associated Layer 3/Layer transportation protocol stacks terminated. Data can be repackaged and routed using an internal, offload protocol which also preserves L3 and/or L4 information. | 04-23-2009 |
20090110003 | HANDLING IP DATAGRAM FRAGMENTS - Problems caused by Internet Protocol datagram fragmentation are solved by creating a session context for the datagram fragments without actually reassembling the datagram from its fragments. The session context enables treatment of the datagram without actually reassembling it. Processing fragments can be followed by forwarding the processed fragments to another node that can further fragment the IP datagram. | 04-30-2009 |
