A system and method of managing power in a hybrid vehicle are provided. The package is defined by a unitary package piece that is divided into a set of sections, and each of the set of sections is capable of having printed data thereon. The apparatus comprises a system, suitable for performing the method, that is capable of reproducing a wide variety of different audio programmes that comprises several phases, the content of each phase not being predictable in advance. The reducing may be used after an oxygen vacancy filling step that causes at least some of the dopant to increase in its oxidation state. The apparatus still further includes at least two offset transmission lines disposed at ends of the carrier amplifier and the peaking amplifier and configured to regulate a load impedance.
