Abstract: Battery-operated device, in particular a display device, comprising a first communication stage for wireless communication, in particular radio communication, with a data processing facility, and a second communication stage which is designed to wirelessly query with an initiator device, which differs from the data processing facility, whether there is a need for communication between the device and the data processing facility via the first communication stage, and wherein the battery-operated device is designed to establish communication with the data processing facility with the aid of the first communication stage if the need exists.

Abstract: Electronic display device (7), which comprises a display module (8) for the visualisation of price and/or product information, which can be received in the course of radio communication with an access point (3A-3D), and which comprises an acceleration sensor (10), which is designed to detect an acceleration of the display device (7), and to provide a detection signal (ED) representing the detected acceleration, and which comprises a communication module (9), which is designed for radio communication with a previously established first access point (3A), characterised in that, the communication module (9) is designed to identify the occurrence of at least two mutually distinguishable patterns over the time profile of the detection signal (ED) provided, and, depending on the pattern identified, either to verify the communication availability of the previously established first access point (3A) for further radio communication, or to determine a second access point (3B) for further radio communication.

Abstract: A tool holder (12) for an indexable cutting insert (13) is disclosed, comprising a tool holder base body (15), having a receiving pocket (20) for receiving an indexable cutting insert (13) and a fastening pin (17). The fastening pin (17) can assume a mounting position and a clamping position. In the mounting position, the fastening pin (17) can be positioned in a fastening opening (14) of an indexable cutting insert (13). In the clamping position, an indexable cutting insert (13) can be fixed in the receiving pocket (20) by means of the fastening pin (17). The fastening pin (17) is arranged on a fastening slide (16), displaceably arranged in the tool holder base body (15). Furthermore, a cutting tool (10) is disclosed, having a tool holder (12) and an indexable cutting insert (13).
