A fastening element, which is used for fastening or fixing a display unit, preferably an electronic display unit, particularly preferably an electronic price- and/or product-information display unit, to a support device, which is preferably designed as a shelf edge strip, the fastening element comprising at least one locking element, which is retractable and extensible and preferably constructed as a pin, which is held in its extended position by a spring, which is provided in the fastening element, and can be moved counter to the force of the spring to a retracted position, characterized in that the fastening element is realized as a separate fastening module.

An electronic shelf label system, comprising a number of display devices to display content on its screen or its screens, each device comprises a memory stage to store content data, and a control stage to control the display of the content on its screen; wherein the screen is a video screen and realizes a shelf rail or covers a front of a shelf rail or a part of it to which it is attachable, and the content is a video and the memory stage stores the entire video data of the video, and the control stage is designed to define a display window for the video and to display only the video content within the display window on its screen.

An electronic display device, particularly product information and/or price information display device, which comprises a screen, and a housing or a housing casing, in which the screen is mounted, and a display device reinforcing structure, which is designed for reinforcing the display device with respect to external action of force.

A support device for supporting a module, wherein the support device comprises an alignment wall for aligning the module which is inserted into the support device and the alignment wall comprises a longitudinal extent and a transverse extent running normal thereto, wherein the support device is designed in such a manner that the module, which is inserted as intended into the support device, can be moved inside the support device in a manner corresponding to or along the transverse extent of the alignment wall between a removal position and a holding position, in which the module is aligned on the alignment wall, and that the shape or the cross section of the support device forms a removal opening at a distance from the alignment wall, through which removal opening the module can only be removed from the support device starting from the removal position.

A bus system, a shelf edge strip bus system in particular, which comprises a first line for determining an electric reference potential, a second line for providing a supply voltage with a desired value in relation to the reference potential, at least one third line, preferably a single third line, for communication of signals and/or data, a supply device, which is electrically conductively connected to the lines and is designed for electric power supply as well as for communication supply of electronic devices which can be connected to the bus system, wherein the supply device is designed to supply different device types both with electric power and with communication, particularly in a device-type-specific manner.

An electronic shelf label, which comprises: a display unit, which is designed for displaying image content, and a communication module, which is designed for wireless communication for the purpose of receiving image data, which represent the image content, and for transferring the image data to the display unit, wherein a detector unit is provided, which is designed for detecting an incorrect positioning, which differs from a desired positioning, of the electronic shelf label, and for outputting an action signal when the incorrect positioning is detected, wherein the detector unit comprises a photodiode, and wherein the electronic shelf label is designed to change the image content when the action signal is present.

Radio base station, having a first radio module for radio communication with first radio communication devices, and a connection for connecting an ESL radio module for radio communication with electronic display panels, wherein the radio base station has a first, in particular software-based, control stage for controlling the radio communication of the first radio module according to a first communication protocol, and a second, in particular software-based, control stage for controlling the radio communication of the ESL radio module connectable to the connection according to a second communication protocol, and a, in particular software-based, third control stage for predictively changing a time sequence, defined for a future period, of radio activities of the first radio module on the basis of radio activities of the ESL radio module that are defined for said future period.
