Abstract: A device and method for creating an arteriovenous (AV) fistula includes a proximal base having a distal diagonal end surface and a distal tip connected to the proximal base and movable relative to the proximal base. The distal tip has a proximal diagonal end surface. A heating assembly, including an energized heating element, is disposed one of the distal diagonal end surface and the proximal diagonal end surface. A passive heating assembly is disposed on the mating diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface are adapted to contact opposing sides of a tissue portion to create a fistula. The angle of the proximal diagonal end surface matches the angle of the distal diagonal end surface, so that the two surfaces match one another during deployment.

Abstract: An electromagnetic pole (17) for a rotary electric machine is disclosed. The pole has a tooth (18) comprising a tooth body (19), the tooth (18) being radially oriented and the tooth (18) comprising a recess (21), a coil (16) comprising a plurality of wire turns (20) wound around the tooth (18) between a first radial end (28) and a second radial end (29), the wire turns (20) which are the most distant from the tooth body (19) between the first radial end (28) and the second radial end (29), forming an outer wire layer (22), the coil (16) comprising a bracing wire (14), the bracing wire (14) being wound on the outer wire layer (22) from the first radial end (28) to the second radial end (29) in less than one turn around the tooth (18) so as to hold in position the outer wire layer (22).

A field coil is wound around each tooth of the plurality of teeth. At least one tooth of the plurality of teeth includes at least one weld seam on a lateral face of the corresponding tooth, the lateral face extending radially and axially along the axis of rotation.

Abstract: Method for producing an active part (1) for a rotating electric machine (101), comprising the following steps: providing a core (2) for the active part (1) and shaped conductors (6) which are inserted into the core (2), joining in each case two of the end faces (9) to one another; and welding a respective pair (10) of the end faces (9) by means of a laser beam which is guided along a pattern having a trajectory (15).

Abstract: A method for producing an active part (1) for a rotary electric machine (101), comprising the following steps: providing a core (2) for the active part (1) and shaped conductors (6) inserted into the core; joining together, in each case, two of the end areas (9) so that the two end areas (9) form a pair (10); and welding each pair (10) of the end areas (9) by means of a laser beam which is guided on the end areas (9) of the pair (10) along a first trajectory (13).

Abstract: A rotor (3a . . . 3c) for an electrical machine (1) is described which comprises several rotor segments (10a . . . 10c, 10a?, 10a?, 10 . . . 10??) which are arranged successively along the rotational axis (x) of the rotor (3a . . . 3c) and each comprise a rotor plate (11) or several rotor plates (11). Magnetic poles (A . . . D) of two adjacent rotor segments (10a . . . 10c, 10a?, 10a?, 10 . . . 10??) are twisted relative to one another around the rotational axis (x) of the rotor (3a . . . 3c) by a staggering angle (?), wherein the staggering angle (?) is smaller than a polar angle (?) lying between two magnetic poles (A . . . D) of a rotor segment (10a . . . 10c, 10a?, 10a?, 10 . . . 10??). The rotor (3a . . . 3c) comprises at least two first cutouts (12) which are arranged on a first hole circle (L1) around the rotational axis (x) of the rotor (3a . . . 3c) and are each twisted relative to one another by an angle (?) which corresponds to the polar angle (?) minus or plus the staggering angle (?).

Abstract: A method for excluding a participant from a group of multiple participants, in which certificates are used for an authorized communication of the participants among each other, a withdrawal request being received by one participant of the group, the withdrawal request making an identification of the participant to be excluded possible by the participant to be excluded itself, and the authorized communication being terminated by the participant when it is identifiable as the participant to be excluded based on the withdrawal request, as well as a communication system for carrying it out.

Abstract: For communication of a first participant with at least one additional participant in a communication system via multiple protocols, the protocols using at least two different certificate formats, the first participant uses different certificates with the respective certificate formats for the communication via the different protocols, the different certificates being based on a shared public key. The first participant holds a shared associated private key for the different certificates. Provision of the certificates for the first participant includes generating the public key and the associated private key, signing the public key for provision of the first certificate, and signing the public key for provision of the second certificate.

Abstract: A telecommunication network, an authentication node, and a method for commissioning an electronically controllable vehicle component of a telecommunication network. For commissioning, the vehicle component requires a verification of authentication data that are to be acquired. For this purpose, the following is carried out: positioning a mobile data carrier in the authentication node of the traffic network, in particular in a vehicle; reading in authentication data of the mobile data carrier within the authentication node; verifying the read-in authentication data and, if verification is successful: producing a verification signal; triggering a verified commissioning of the component if the verification signal is acquired at the vehicle component or at a control device of the node at which the component is situated.
