  • Patent number: 7429354
    Abstract: A microfluidic device that comprises several microchannel structures in which there are an inlet port, an outlet port and therebetween a substructure comprising a fluidic function. The device has an axis of symmetry around which the microchannel structures are arranged as two or more concentric annular zones. for an inlet port and an outlet port of the same microchannel structure the inlet port is typically closer to the axis of symmetry than the outlet port. Each microchannel structure comprises a substructure that can retain liquid while the disc is spun around the axis and/or the inlet ports are positioned separate from the paths waste liquid leaving open waste outlet ports will follow across the surface of the disc when it is spun. For the microchannel structures of an annular zones the corresponding substructures are at essentially at the same radial distance while corresponding substructures in microchannel structures of different annular zones are at different radial distances.

  • Publication number: 20080201403
    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.

    Abstract: A pipe line for a turbocharger system for an internal combustion engine has at least one exhaust line for the evacuation of exhaust gases from the combustion chamber of the engine to the turbocharger system and at least one inlet line for the supply of air to the combustion chamber. The turbocharger system includes at least one turbine, which cooperates with at least one compressor to extract energy from the exhaust flow of the engine and pressurize the inlet air of the engine. To allow a compact installation with low pressure losses, the inlet line connects with a curved line section of an outlet from the compressor, at least a part-section of the curved line section having a non-circular cross section. A diffuser is placed less than five pipe diameters downstream of the curved line section.

  • Publication number: 20070291772
    Abstract: A node member of a cluster in a network comprising a plurality of nodes and a method related to the capabilities of the node, which is capable of maintaining a stable view of the cluster's membership, maintaining a list of neighboring nodes sharing a same updated view of the cluster's membership and receiving a confirmation message from a second node confirming that a new view received therein should replace the stable view and become a new stable view. The node is further capable of verifying that the new view is up to date in comparison to the same view and, if the new view is not up to date, discarding the confirmation message.
