Abstract: The present disclosure is directed to an audio delivery system including an audio source, an audio conversion device, a wireless transmitter, and mobile devices. The audio source is configured to deliver raw audio output in a first format to the audio conversion device. The audio conversion device is configured to receive the raw audio output, parse the raw audio output into data packets, transmit the data packets to a network location for conversion into a second format, receive the converted data packets from the network location, and transmit the converted data packets over a wireless network. The wireless transmitter is configured to generate a wireless network in a localized area for transmission of the converted data packets to the mobile devices. The mobile devices are configured to receive instructions from a user, receive the converted data packets, and present the converted data packets to the user in the second format based on the user instructions.

Abstract: The invention relates to a method for maintaining and/or repairing the spout area (1) of a metallurgical vessel, wherein a substantially hollow-cylindrical sleeve (3) in a perforated brick (2) of the metallurgical vessel is removed. In order to allow the sleeve to be replaced quickly and simply in the event of wear, the method according to the invention has the following steps: a) introducing at least one radially extending slit (4) into the sleeve (3), whereby the sleeve (3) is interrupted at at least one circumferential point (5); b) reaching behind the sleeve (3) or segments (3?, 3?) thereof with a pulling tool (6); c) pulling the sleeve (3) or segments (3, 3?) thereof out of the perforated brick (2), and d) inserting a new sleeve (3) or a new brick material into the perforated brick (2).

Abstract: In the case of a robot interaction system comprising a robot (1) having a robot controller with types of operation and operating modes which influence an associated man-robot interface, the aim is to provide a solution which allows flexible matching of a robot or robot system to different degrees of a man-robot interaction. This is achieved in that the robot controller is equipped with types of operation and operating modes which influence an associated man-robot interface and are designed to be matched and/or to be capable of being matched to different automation degrees of the robot (1) and/or to different time and/or physical positions of the man and robot as interaction partners in a working area.
