Abstract: A wireless IO-link communication network has a main master and at least one device which have a bidirectional wireless communication between the main master and the at least one device, as well as a backup master which is connected to the main master and the at least one device and is configured to control the at least one device. In a method for operating the IOLW communication network with such a backup master, the backup master controls the at least one device instead of the main master.

Abstract: A method is provided for operating an electrical device (14) which has an operating mode and a sleep mode, in which method an oscillator apparatus (20) provides a first analog signal (f(t)) with a first frequency and second analog signal (f?(t)) with a second frequency, wherein the second analog signal (f?(t)) is different from the first analog signal (f(t)), a comparator apparatus (28) compares the first analog signal (f(t)) and/or second analog signal (f?(t)) with at least one reference value (Uref) or a reference value range, and an interrupt signal for transferring from the sleep mode into the operating mode is produced if a certain comparison result is detected.

Abstract: A method for the activation of an electrical device (50), which comprises at least one electrical component (30) whose values are mechanically variable by rotating or displacing is characterized by the following steps: at least one first and one second threshold value are predetermined, which are adjustable by rotating, touching, displacing or other manipulations; a time window starts after reaching the first threshold value by manipulation of the electrical component (30); if the second threshold value is reached by manipulation of the electrical component (30) within the time window, an activation signal is output; and if the second threshold value is not reached within the predeterminable time window by manipulation of the electrical component (30), the activation process is terminated.

Abstract: A loudspeaker system includes a loudspeaker housing comprising at least one opening for accommodating a loudspeaker, wherein a guide element and an electrical connecting element on the housing side is associated with each opening. The system includes at least one loudspeaker unit, comprising a loudspeaker and frame with a corresponding guide element and an electrical connection element on the loudspeaker side of the frame.
