  • Patent number: 7148476
    Abstract: The present invention relates to a method for presenting an analyte of a liquid sample as an MS-analyte to a mass spectrometer. More particularly, the method comprises the steps of applying a liquid sample containing the analyte to a sample inlet port of a microchannel structure of a microfluidic device, said structure also comprising an outlet port (MS-port) that is capable of being interfaced with a mass spectrometer, passing the analyte to the MS-port thereby transforming it to an MS-analyte, and presenting the MS-analyte to mass spectrometer via the MS-port.

  • Patent number: 7104517
    Abstract: The invention relates to a method of controlling flow of liquids in a micro channel structure. It comprises providing in said micro channel structure plugs (34) of polymer material in said structure, said polymer material in a first state blocking said channel from liquid flow, and in a second state providing a free path-way (32) for liquid flow. Energy is selectively applied so as to cause said polymer to enter a desired one of said first or second states. It also relates to a micro channel valve system, comprising a plurality of such plugs (34). Additionally it comprises a chemical reactor, comprising a plurality of micro chambers interconnected by micro channels, having a valve system according to the invention.

  • Publication number: 20060179013
    Abstract: A method and a distributor are provided for ensuring efficient and expandable distribution of signals in a network. Distribution rules are defined by configuration in a distributor. A rule comprises one or more patterns used to attempt finding a match with a signal content. A result of a match attempt in a rule may lead to a destination for the signal content or to another rule. Rules are assembled hierarchically to form a decision tree. A network of distributors may be used instead of a single distributor. Functional units use distributors to exchange signals content. A configuration of the decision tree can be modified without impacting ongoing signal distribution. Functional units can be added, split or otherwise reorganized without having to cater for signal distribution modifications.

  • Publication number: 20060123787
    Abstract: A turbocharger system for an internal combustion engine having at least one exhaust line (15, 16) for evacuating exhaust gases from the combustion chamber of the engine and at least on inlet line for supplying air to the combustion chamber. A high-pressure turbine (17) interacts with a high-pressure compressor (19) and a low-pressure turbine (21) interacts with a low-pressure compressor (23) in order to extract energy from the exhaust flow of the engine and pressurize the inlet air of the engine. Both compressor stages are of the radial type and are provided with compressor wheels having backswept blades, in which a blade angle between an imaginary extension of the blade along the centerline between root section and tip section in the direction of the outlet tangent and a line connecting the center axis of the compressor wheel to the outer point of the blade, is at least about 40 degrees.

  • Publication number: 20060123786
    Abstract: A turbocharger system for an internal combustion engine (10) having at least one exhaust line (15, 16) for evacuating exhaust gases from the combustion chamber (11) of the engine and at least one inlet line (12) for supplying air to the combustion chamber. A high-pressure turbine (17) interacts with a high-pressure compressor (19) and hereupon forms a high-pressure turbo unit (18) with a common rotation axis. A low-pressure turbine (21) interacts with a low-pressure compressor (23) and hereupon forms a low-pressure turbo unit (22) with a common rotation axis, for extracting energy from the exhaust flow of the engine and pressurizing the inlet air of the engine. The low-pressure turbine (21) is of the axial type.

  • Publication number: 20060123785
    Abstract: A turbocharger unit (18) for an internal combustion engine (10) with at least one exhaust line (15, 16) for conducting exhaust gases away from the combustion chamber (11) of the engine and at least one inlet line (12) for supplying air to the combustion chamber. The turbocharger unit includes a turbine (17) which interacts with a compressor (19) for extracting energy from the exhaust gas flow of the engine and pressurizing the inlet air of the engine. The compressor (19) is of radial type and provided with an impeller with backswept blades (35) where the blade angle (?b2) between an imaginary extension of the center line of the blade between root section and tip section in the direction of the outlet tangent and a line (36) which connects the center axis of the impeller to the outer tip of the blade is at least roughly 45°. The turbine (17) which drives the compressor (19) is of radial type.

  • Publication number: 20060111691
    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. The catheter may also be used to diagnose urinary retention problems caused by a weak bladder or a prostatic obstruction.

  • Publication number: 20060031369
    Abstract: A method, system and Edge Multimedia Messaging Service (MMS) Relay/Server for handling MMS messages in an MMS system, wherein incoming MMS messages are received at the Edge MMS Relay/Server from User Agents (UAs). The former determines criteria associated with the MMS messages and based on the criteria, selectively forwards the MMS messages to the proper MMS Relay/Server of a second stage of the MMS system, where the MMS messages are handled based on their type, and further delivered to the MMS recipients. Such criteria may include the retrieval time of the messages, the type of subscription of the user (prepaid vs postpaid), the need for transcoding the MMS message, and immediate vs future delivery time.
