Abstract: The present invention provides a circuit arrangement comprising a clock conductor (230-3) coupled to a number of circuit components (210-c, 210-d, 210-e), each said circuit component being coupled to the clock conductor with a respective filter (240-1, 240-2), wherein at least one of the filters is arranged to pass a clock signal having a first frequency and at least one of the other filters is arranged to pass a clock signal having a second frequency.

Abstract: A communications device (100) and method (200) for automatically personalizing user interface parameters of an accessory (120,140) operatively coupled to the communications device (100). The communications device (100) and the method (200) provide for reading (260) a pre-defined user interface setting stored in a memory of the accessory, the reading being performed by the communications device (100) and the pre-defined user interface settings being pre-selected by a user of the accessory (120,140). Thereafter, the communications device (100) and the method (200) effect a controlling (270) of a user interface parameter of the accessory (120,140), the controlling being effected in response to the reading (260) of the pre-defined user interface setting.

Abstract: A communications device (100) and method (200) for automatically selecting features of accessories (120,140) operatively coupled to the communications device (100). In use the method (100) includes detecting operative coupling (220) of accessories (120,140) to the communications device (100) and then determining (240) a common feature supported by the accessories (120,140). Thereafter, the method (200) provides for selecting (250) one of the accessories (120,140) to provide the common feature the selecting (250) being determined by a sequence of the operative coupling.
