摘要:
A gateway (70, 70(2), 70(3)) of a telecommunications network (20) is arranged for performing protocol signaling conversion for communicating call setup signaling to an IP Multimedia Subsystem (IMS) (40), and upon completion of call setup is arranged to route user traffic between local mobile stations (22) involved in a connection without routing the user traffic to the IP Multimedia Subsystem (IMS) (40). In an example implementation, the signaling protocol is suitable for use over an interface between a circuit switch domain core network node and a radio access network includes GSM 24.008 signaling and the signaling protocol for a IP Multimedia Subsystem (IMS) is Session Initiation Protocol (SIP) signaling. The gateway can be situated in any of several locations such as, for example, at a mobile switching center (MSC) node (60), at a base station controller node (50) of the radio access network (RAN) (24), or at a node distinct from a mobile switching center node (MSC) and a base station controller (BSC) node, e.g., at a dedicated gateway node.
摘要:
A telecommunications network comprises a base station node (28) which provides plural sets of radio transmission resources (52) for communicating with mobile stations (30) in a cell (40). At least one set (521) of radio transmission resources of the cell is a non-hopping set of radio transmission resources including a resource which may carry the BCCH, and other sets (521-52n) of radio transmission resources of the cell are hopping sets of radio transmission resources. A base station controller (26) node schedules calls comprising voice over internet protocol packet flows on the non-hopping sets of radio transmission resources in accordance with capacity of the non-hopping set of radio transmission resources. When the non-hopping set of radio transmission resources lacks capacity for a further call with a mobile station, the base station controller (26) node requests that the call be changed from a voice over internet protocol packet flow to a circuit switched connection.

A combustion engine with compression-initiated combustion comprises at least one cylinder in which a piston is movable axially between a lower dead center point and an upper dead center point, with a dead volume between the cylinder and the piston at the upper dead center point. The dead volume comprises at least two substantially separate spaces in the piston and/or the cylinder at the upper dead center point which are designed to ensure that combustion is initiated at different times.

A method for fuel injection in a four-stroke combustion engine (1) of piston-and-cylinder type with compression ignition, whereby a specified fuel quantity is supplied to a combustion chamber (2) for each working cycle, and whereby EGR gases are led back to the combustion chamber (2). At least a first portion of said fuel quantity is combined with hot EGR gases for supply to the combustion chamber (2). The invention also relates to a combustion engine working according to the method.

In a method for shielding electronics, a plurality of components to be shielded are arranged on a part of an assembly base to be shielded, each of the plurality of components having a first side including a first contact surface connectable to a common earth connection of the assembly base, each of the plurality of components further having a second contact surface, the plurality of components being arranged such that, for each of the plurality of components, the first side with the first contact surface faces out toward a periphery of the part of the assembly base. For each of the plurality of components, the first contact surface is connected to the earth connection. The plurality of components are shielded with a shielding device. For each of the plurality of components, the first contact surface is closer to the shielding device than the second contact surface.

A inventory information system having an inventory station having an array of unique locations defined thereon; a plurality of indicators, each of the indicators being associated with each of the locations; a plurality of tags, each of the tags having an identifier associated therewith; at least one detector operable to obtain identifier associated with one of the tags when the tag is positioned at one of the locations; and a processor operatively coupled to the at least one detector and the plurality of indicators. The processor is configured to receive the identifier and to determine an inventory status of at least one product associated with the identifier, and operate the indicator associated the location where the tag based upon the inventory status to provide information about the inventory status.
摘要:
The invention relates to a process for making porous cross-linked charged cellulosic polymeric membranes capable of binding to a target molecule. The invention provides methods for separating target molecules from other components in a solution comprising use of membranes obtainable by the process of the invention. The method has particular utility in separating proteins and nucleic acids from cell lysates and cultures.
摘要:
A life consumption of a component in a machine may be predicted. Load data may be received from a load session of said machine. A plurality of parameter sets may be accessed, each associated with a critical point of said component, which point is considered to have critical life consumption. For each critical point, life consumption may be calculated using a life consumption calculation model receiving said load data and said parameter sets as input. By selecting a plurality of critical points on the component, a more complete view is presented of how the different parts of the component are affected by the load session.
摘要:
A pump system that includes a pump, an injector and a regulator with a calculation unit. The regulator controls the pump to pump a liquid through a hose to the injector which opens and closes in response to an injector control signal, the time for an opening and closing cycle being called injector cycle and designated Ts, and the injector's open period being designated γ. The injector has a pressure sensor to measure the pressure of the liquid in the injector and to deliver to the calculation unit a pressure sensor signal representing the pressure amplitude in the injector. The calculation unit calculates the hose's rigidity B as a function of measured pressured amplitudes A in the injector, the injector cycle Ts and the injector's open period γ, and the regulator determines the basis of B the control signal to the pump.
