A method and an apparatus for wireless communications comprising determining that a first handover from a source cell to a target cell has failed; and performing a second handover from the source cell to a first neighbor cell different from the source cell and from the target cell. , the present invention relates to a sound synthesizer system for use in a vehicle having an internal combustion engine. The drive subsystem includes a reciprocating motor-driven block engaging the carrier and moving the carrier back and forth in a predetermined longitudinal path extending along a longitudinal axis from an entrance station to a plurality of processing stations in the sample testing machine. That is, when depositing metal in complex ions on the fuel cell separator by an electrodeposition process, the metal is adhered not only to a power generation region but also to a portion where the surface is exposed by the defects of the resin coat, thereby forming the metal coat on the defects.
