A component composite, in particular for motor vehicle applications, include a first component having a first contact surface and at least one second component having a second contact surface, which presses against the first contact surface, the first contact surface having a surface structure, which is produced using electromagnetic radiation. The surface structure has a microstructure overlaid by a nanostructure.
摘要:
The invention relates to a method for generating at least one through-hole (3, 4) in a wall of a workpiece (2) bounding a hollow space (12) of the workpiece (2), said method using a laser beam (7) directed onto the wall (9) from the exterior. A paste-like protective agent (13) is thereby introduced into the hollow space of the workpiece (2). The paste-like protective agent (13) is applied in an extension (10) of the laser beam (7) guided through the through-hole (3) in front of a rear wall bounding the hollow space (12). Reliable protection of the rear wall (11) during laser drilling of the through-hole (3) is thereby ensured.
摘要:
A device having at least one semiconductor component, which is covered by a protective material on its outer surface. The invention provides for the outer surface to be provided with a surface structure so as to enlarge the heat transfer area to the protective material. The invention furthermore relates to a manufacturing method.

The present document relates to media players, such as portable electronic devices, vehicle audio systems, home stereo systems, etc. In particular, it relates to the management of the sound pressure level generated by portable electronic devices. A method and system for controlling the cumulated audio dose of a user of a media player is described. The method comprises the steps of determining the audio dose already consumed by the user and of selecting one or more media tracks for play back on the media player based on the audio dose of the media track and the already consumed audio dose of the user.

The present disclosure relates to media players, such as portable electronic devices, vehicle audio systems, home stereo systems, etc. In particular, it relates to the management of the sound pressure level generated by portable electronic devices. A method and system for controlling the consumed audio dose of a user of a media player is described. The method comprises the steps of selecting a first frequency range from the total frequency range relevant for the human ear; of determining the audio dose already consumed by the user within the first frequency range; of evaluating the audio dose of a media track within the first frequency range and the already consumed audio dose of the user within the first frequency range; and of controlling the audio dose generated by the media player based on the evaluating step.
