Abstract: A method adapts a representation of musical contents. The method includes generating a musical content representation centered on a first musical content and playing the musical content on which the representation is centered. The musical content on which the representation is centered is played so long as no action is undertaken by the user. The method also includes playing a new track when an action ending the play of the musical content is undertaken by the user, continuing the play of the musical content when an action not ending the play of the musical content is undertaken and the action is taken into account, playing new musical content when the play of the musical content on which the representation is centered is finished, and modifying the representation with each new play of a musical content so as to be centered on the new musical content played.

Abstract: A device balancing overall levels of electrical charge in plural blocks of cells in a battery. The blocks can be connected in a circuit during a charging phase of the cells accumulating charge, and during a discharging phase of the cells giving back charge. The device includes one series switch and one parallel switch. The series switch can, when closed and the parallel switch is open, connect a block to the circuit, in series with the other blocks, so that the block is connected during the charging and discharging phases. The parallel switch can, when closed and the series switch is open, disconnect the block from the circuit, so that the block is disconnected if discharging disconnection conditions are met during the discharging phase or if charging disconnection conditions are met during the charging phase. The block includes a mechanism locally balancing charge levels of its cells when disconnected.
