Abstract: The invention relates to a broadband high power amplifier that comprises a signal input adapted to receive an input signal, at least one amplifier stage adapted to amplify the received input signal, a signal output adapted to output the signal amplified by the at least one amplifier stage as an output signal, a monitoring unit adapted to monitor signal characteristics of the input signal and the output signal and a control unit adapted to operate the at least one amplifier stage at an optimal operating point depending on the current signal characteristics monitored by said monitoring unit.

Abstract: A system for machining materials by means of laser beam includes a deflection device for deflecting the laser beam and a wobble device configured to superimpose a wobble movement of the laser beam with a wobble figure and a wobble frequency onto a feed movement of the laser beam corresponding to a machining path by controlling the deflection device. The wobble device is configured, for carrying out the wobble movement, to control the deflection device according to a compensated wobble movement. Control values for a deflection of the laser beam along the wobble figure are adapted as a function of the wobble frequency and/or a path speed of the wobble movement that varies along the wobble figure is adapted as a function of a position of the laser beam in the wobble figure and as a function of the wobble frequency.

Abstract: Systems and methods for structuring metadata associated with digital media content such as images and videos are disclosed. Use of an existing hierarchical taxonomy provides a set of structured metadata to organize unstructured data stored in an electronic media archive. As digital media content is submitted to the archive, metadata keywords are user-selected from the existing taxonomy to identify and describe the digital media content, and to position the content within the hierarchical structure. The selected metadata keywords can then be automatically associated with synonyms and related terms to build an ontological network that facilitates efficient retrieval of the content when searching the electronic media archive. Each node in the taxonomy is then linked to its foreign language counterparts, allowing the content to be located in an international search.

Abstract: A first privacy setting notification is provided to a user. Events are monitored to determine satisfaction of a privacy trigger condition based at least in part on the first privacy setting notification. A second privacy setting notification is provided to the user in response to the satisfaction of the privacy trigger condition.

Abstract: In a machining method for machining a curved workpiece surface (210) of a workpiece (200), a roll-embossing operation is carried out. At least one rolling element (180A, 180B, 180C) of a machining tool (100) is rolled here under a contact pressure against a section (198) to be machined of the curved workpiece surface. An external surface of the rolling element has a rough surface structure in at least one working section (190A, 190B, 190C) intended for rolling contact with the workpiece surface. The contact pressure is set in such a manner that, during the rolling, a rough roll-embossed structure is produced by local deformation of workpiece material without removing material in the machined region of the workpiece surface. The machining method can be used, for example, for machining the internal surface of a bore in a workpiece, in particular for roughening the workpiece surface for a subsequent coating.
