Abstract: A control device for selectively controlling a power supply from a power source via at least one of a first output and a second output. The control device including at least one processor and at least one memory storing at least one portion of computer program code, the processor being configured to cause the control device to obtain an indication of at least the following parameters: a charge level of the power source, power need from the first output, a power need from the second output; and selectively adjust the power supply via the first output and via the second output from the power source in dependence of the parameters. A power supply arrangement includes the control device.

Abstract: Disclosed is a method for operating an arrangement of a mobile communication device that includes an audio processor communicatively coupled to an accessory device that includes an audio transducer is provided, the method including adjusting at least one operating parameter in one or both of the audio processor and the audio transducer, the adjusting including obtaining, via the communicative coupling from the accessory device, an accessory type identification assigned for the accessory device, obtaining a device type identification assigned for the mobile communication device, selecting a respective predefined value for each of the at least one operating parameter in dependence of the obtained accessory type identifier and the device type identifier, and setting each of the at least one operating parameter into respective selected values for subsequent operation of the arrangement.
