Abstract: The invention relates to a drive module for a vehicle, wherein the drive module is adapted to be releasably connected to a functional module for forming an assembled vehicle, the drive module comprising: at least a pair of wheels; at least one propulsion unit connected to the pair of wheels; at least one energy storage unit for providing the propulsion unit with energy; a control device configured to operate the drive module as an independently driven unit; and at least two interfaces for releasable connection with a functional module, each interface being arranged on different sides of the drive module. The invention also relates to a vehicle assembled from a set of modules.

Abstract: The invention relates to a method performed by a first control device for controlling assembly of a vehicle from a set of modules, the set of modules comprising: at least one drive module and at least one functional module, wherein the at least one drive module comprises a pair of wheels and is configured to be autonomously operated, and wherein each module in the set of modules comprises at least one interface releasably connectable to a corresponding interface on the other module, the method comprising: commanding a second control device of the at least one drive module to physically connect the at least one drive module with the at least one functional module to assemble a vehicle; and receiving, from at least one of the modules of the assembled vehicle, a verification of the connection between the modules.

Abstract: A network status measuring system comprising a processor; a display circuitry configured to display a schematic overview of the network; a data traffic measuring circuitry configured to measure bit rate and latency on links of the network; and a graphic generating circuitry configured to generate a graphical representation of a bit rate and a latency measured on a particular link of the network by generating objects to be displayed at the particular link of the network in connection with the schematic overview of the network. The processor is further configured to calculate a number of the objects to be displayed at the particular link of the schematic overview of the network based on the bit rate measured on the particular link of the network. The display circuitry is further configured to display the generated objects at the particular link of the schematic overview of the network.

Abstract: A method for requesting and receiving a media stream within a networked system is provided. The networked system includes a client, a media service register (MSR) and a media service manager (MSM), arranged to communicate within a data network including networked computing devices. The method includes: the client sending to the MSR a media request for the media stream, the MSR including a register of identifiers and an address for accessing each active media stream generating services (MSGS); the MSR checking if the media request matches an active MSGS generating the requested media stream; when the media request does not match an active MSGS, sending an activation request to the MSR for a MSGS generating the requested media stream; the MSM sending an instruction to install the requested MSGS at at least one of the networked computing devices; and the client receiving the media stream generated by the installed MSGS.

Abstract: A packet radio data network and methods have been disclosed, the network comprising at least a gateway node (GGSN), at least one serving node (SGSN) connected to the gateway node, a plurality of radio access nodes (RAN) connected to the serving node (SGSN), the packet radio network transporting packet data from an external packet data network, comprising an Internet Service Provider (ISP), to mobile stations (MS) wirelessly attached to radio access nodes (RAN). The gateway node, subsequent to a PDP multipoint context activation procedure, establishes at least a first multicast tunnel (GTPT1 GTPT4, GTPT10 GTP35) between the gateway node and at least one serving node, the multicast tunnel carrying IP streams pertaining to at least two mobile stations belonging to a common multicast group.
