  • Patent number: 7724776
    Abstract: 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.

  • Publication number: 20100106142
    Abstract: A partial-length catheter, or an extendable tube or sleeve member of the catheter, is selectively movable within the prostatic urethra to open a urine drainage passageway through and obstructed portion of the prostatic urethra or to open the external urinary sphincter muscle and thereby discharge urine from the bladder. A control element is manipulated at a position exterior of the urinary canal to selectively move the catheter or the extendable tube or sleeve member, thereby selectively controlling urine discharge.

  • Patent number: 7574862
    Abstract: A turbocharger unit for a multicylinder internal combustion engine has at least two exhaust lines for the evacuation of exhaust gases from the combustion chamber of the engine and at least one inlet line for the supply of air to the combustion chamber. The turbocharger unit 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. The turbine is provided with a worm-shaped housing having at least two flow paths which are defined by guide tongues in the housing and which conduct mutually separate exhaust flows via stator blades to at least one turbine wheel. In order to maintain the kinetic energy in the separate exhaust flows, each respective guide tongue meets a stator blade extending toward the tongue.
