Abstract: The invention relates to a controlling arrangement for a music player application in a mobile communication device. To improve the control of the music player, a multifunctional soft button (100) with four switching positions (up, down left and right) and a mode switching arrangement (110) are provided on the keyboard layout (10). The application can be switched in two different modes with the switching arrangement and can be controlled with the multifunctional soft button, the latter having different functionality depending on the mode of the application. Combined functionality of the multifunctional soft button from the first and second mode is also possible. Additional symbols related to the music player functionality are printed in different colors on the multifunctional soft switch.

Abstract: The present invention relates to a mobile communication device having a keyboard and a method for controlling the operation of the keyboard of such a mobile communication device. The keyboard provides a QWERTY styled layout including a keypad similar to a ITU-T keypad. Applications executed on the mobile communication device are adapted to switch an operation mode of the keyboard such that in accordance with a certain expected information input, different assignments of the keys of the keyboard are active. The keyboard operation modes improve the usability of the keyboard and allow the number of total keys for operating the mobile communication device to be reduced resulting in lowered cost of manufacture.

Abstract: The invention describes a communication appliance (2) having an emergency battery (10) which can be inserted and which is provided with an electronically readable nominal coding; a read device (11) for identifying the nominal coding or a different coding; a signal generating device (11) for producing a new battery identification signal when the nominal coding is identified; and a write device (11, T) which, after the nominal coding has been identified, converts this coding into a different coding.

Abstract: An electronic communications device contains at least two modules (7, 8) which are connected to one another via an optical bus (4). In an energy-saving mode, each of the modules (7, 8) is switched to receive with a sampling period (P) which is the same for all modules (7, 8), and for a sampling time interval (T) which is short in comparison with the sampling period (P). One of these modules (7, 8) sends an interrupt signal (I) to the optical bus (4), whose duration is equal to or longer than the sampling period (P). At the latest on reception of the interrupt signal (I), the other module (7, 8) is switched to permanent receive in the next sampling time interval, so that data communication can then take place via the optical bus (4).
