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.

Abstract:
A plurality of networked devices on a communication network host services and instances of those services. These services and service instances are mapped onto destination addresses within a given address space. Thus, the destination addresses provide information about the location of the networked devices, as well as the functional topology of the network. Data packets may be routed to a desired service instance using these destination addresses.
Abstract:
In a magnetically-coupled liquid mixer (10) of the type having a drive mount (4) secured to and extending into a mixing vessel (2), an external first magnet array (26) adjacent to the drive mount, a stub shaft (16) extending from the drive mount into the vessel and having a first thrust bearing surface (18T)3 and a driven portion (12) rotatably-mounted on the stub shaft and having a second thrust bearing surface (20T) and a second magnet array, the improvement wherein the first and second arrays are positioned with respect to one another such that the first and second thrust bearing surfaces are spaced apart at least in the absence of above-threshold fluid dynamic thrust forces on the driven portion.
Abstract:
The present invention relates to microfluidic systems using rotating microfluidic disc platforms comprising microchannel structures. More specifically, the present invention relates to a method and an arrangement for controlling magnetic particles in microchannel structures of a microfluidic device. The invention is based on the counterbalancing of the magnetic force and the centrifugal force on the beads when rotating the microchannel structures at different speeds close to an array of magnets.
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.
Abstract:
A centrifugal based microfluidic device that comprises a microchannel structure in which there is a detection microcavity which in the upstream direction is attached to an inlet microconduit for transport of liquid (transport microconduit) to the detection microcavity and which is used for detecting the result of a reaction taking place in the detection microcavity or in a reaction microcavity positioned upstream of the detection microcavity. The detection microcavity comprises a detection microconduit having an inlet part and an outlet part and therebetween an upward or a downward meander.
Abstract:
A microfluidic device (1) comprising a hydrophilic microchannel structure (2) in which there is a functional unit that comprises a microconduit I (17) in which there is an inlet end (16), an outlet end (18), and a capillary stop function I (24) in the form of a local non-wettable surface area (44). The capillary stop function (24) defines a segment of microconduit I (17). Microconduit I (17) is within at least a part of this segment (46) divided into two or more microchannels (42). A part of the non-wettable surface area (44a,b) is associated with an inner wall of each of the microchannels (42).
Abstract:
A microfluidic device comprising a hydrophilic microchannel structure in which there is a functional unit that comprises a microconduit which a) is intended for the transportation of liquid aliquots, and b) has an inlet end and an outlet end between which there is a capillary valve I. Microconduit I comprises an upwardly directed section that extends over a part of or over the full length of microconduit I. Capillary valve I is preferably placed in this section.
Abstract:
A linear electromechanical actuator (10), for a steering system of the "center take-off" type in a motor vehicle comprises: two electric motors (20, 30) each having a stator (23, 33), and a rotor (23, 33), a screw mechanism (40) having an axially stationary innerscrew (42) coupled to the rotors (22, 23) of the motor for rotating about an axis (x), and an outer nut (43) rotationally fixed and axially translatable along the axis (x), a connection block (47), axially translatable with the nut (43), for connecting the nut to two tie rods (A, B) of the steering system.
