A positive electrode active material and a nonaqueous electrolyte secondary battery containing a lithium-containing composite metal oxide having a composition represented by: Li1+yM1\u2212y\u2212zM1zPO4 where M is at least one of Co and Ni, and M1 is at least one of Mg, Zr and Al, the molar ratio y is larger than 0 and smaller than 0. The driving assembly has an input axle and at least one driving gear. At these peaks the phases are rotated using the phase vocoder algorithm. The theft prevent device further includes further includes a trigger switch linked to the security module for sending a trigger event signal instructing the security module when an individual leaves the vehicle or when an individual returns to the vehicle. A recovery channel is positioned to recover liquid from between the heat sink and the chip, and an exhaust member is provided to carry liquid from said recovery channel to the exterior of the heat sink.
