Abstract: A method of performing network handover between wireless local area network devices for a mobile device connected to a voice service via a secure data tunnel to a packet data gateway of a cellular network including determining that a quality of a connection to a current wireless local area network is below a threshold value; determining that a handover target network is available; establishing connectivity with the target handover network; suppressing a connection to a base station of the cellular network; sending a new network address of the mobile device to the packet gateway using a set of credentials relating to the secure data tunnel so as to change an endpoint of the secure data tunnel to the new network address.

Abstract: Device for tensioning a threaded rod comprising an actuator able to exert an axial tensile force on the threaded rod with respect to a structure to be tensioned, the said tension device comprising a cylinder, a piston, a tubular skirt in contact with the cylinder and a surface of the said structure to be tensioned, and a tie for transmitting the axial tensile force of the actuator towards an end of the threaded rod. The tie and the tubular skirt each comprise at least two semicylindrical parts each having two substantially planar axial surfaces, the two axial surfaces of one semicylindrical part being joined radially respectively with one of the two axial surfaces of the other semicylindrical part, so as to form a part of revolution.

Abstract: The invention relates to a device for tensioning a threaded rod (1). The inventive device comprises: an actuator (5) which can exert an axial force; and a tie rod (6) which transmits the axial force from the actuator (5) towards a threaded end (1b) of the rod (1b), said tie rod (6) comprising at least two jaws (31) which can move radially between a closed position, in which the tie rod (6) is engaged with a threaded end (1b) of the rod (1), and an open position in which the jaws (31) are disengaged from the threaded rod (1b). Moreover, said device comprises a locking element (45) which can move between a jaw (31) opening position and a jaw (31) closing position.
