Abstract: Stator for an electric machine, having a stator core with two axial end sides, a stator winding which extends through the stator core in the axial direction and is formed from a plurality of conductor segments, and covers of a first and a second type. The conductor segments have, at one of the end sides, end sections which are electrically conductively and mechanically connected to one another in pairs to form end section arrangements. The covers of the first type each cover at least two end section arrangements at their free end, and the covers of the second type each cover at least one end section arrangement at their free end.

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.

Abstract: A fluid servo actuator control/damping mechanism and method which utilize and combine the functions of an electro-mechanically driven servo valve to achieve ram or actuator fluid flow and load control even after loss of fluid power as well as the main ram position control function under normal operating conditions.
