Abstract: An apparatus (10) configured to be connectable to a first electronic device (12) and a second electronic device (14). The apparatus comprises: a memory (16); a rechargeable battery (18); a real time clock (20); and engagement means. The engagement means is configured to releasably hold the apparatus in engagement with the first electronic device (12) to establish a first physical communication link between the apparatus (10) and the first electronic device (12). The engagement means is configured to releasably hold the apparatus in engagement with the second electronic device (14) to establish a second physical communication link between the apparatus (10) and the second electronic device (14). When held in engagement with the second electronic device (14) the apparatus (10) is configured to receive current time data from the second electronic device via the second physical communication link for storage in the real time clock (20), and recharge the rechargeable battery by the second electronic device (14).

Abstract: A method comprises converting an audio frequency domain signal into one or more voltage signals. Then the characteristics of the one or more voltage signals are determined. Afterwards the characteristics of the one or more voltage signals are compared with one or more characteristics of an audio trigger command. Activation of an audio user interface is then activated on the basis of the comparison.
