Abstract: A feedthrough includes: a main body including at least one passage opening running through the main body, the main body including titanium or a titanium alloy; an insulation material accommodated in the at least one passage opening running through the main body, the insulation material including glass, the insulation material having a contact angle of less than 90 degrees at least in a plurality of regions of the insulation material with respect to the main body; and at least one electrical conductor extending through the insulation material accommodated in the at least one passage opening.

Abstract: A method of assessing a log-file is described. A log-file to be assessed is received. A data storage is accessed that includes several log-files. A group of log-files from the several log-files stored in the data storage is identified. The group of log-files includes log-files that are nearest to the log-file to be assessed. The identified group of log-files is returned to a user for further analysis. Further, a method of grouping several log-files as well as a system for processing at least one log-file are described.

Abstract: A measuring device serves the purpose of performing measurements of a measuring signal generated by a device under test. The measuring signal uses carrier aggregation of at least a first carrier and a second carrier. The measuring device comprises a high-frequency unit adapted to receive the measuring signal comprising the first carrier and the second carrier and a control unit. The control unit comprises a measuring unit adapted to perform measurements on the received measuring signal. While performing these measurements, it is assumed that an alignment of a power of the first carrier and a power of the second carrier is present. Moreover, the control unit comprises a power alignment determination unit adapted to determine, based upon results of the measurements of the measuring unit, whether the power of the first carrier and the power of the second carrier are in alignment.
