This invention provides a branched polycarbonate resin obtained from a dihydric phenol compound, a branching agent, monohydric phenols and phosgene by an interfacial polymerization reaction method in the presence of an alkali aqueous solution and an organic solvent, the branched polycarbonate resin having features that: the branching agent content thereof is over 0. The invention relates to the seeds of soybean cultivar SO22214, to the plants of soybean SO22214 and to methods for producing a soybean plant produced by crossing the cultivar SO22214 with itself or another soybean variety. The apparatus and method set a file name of a scanned document to identify the document without an additional input. The electrical waveform signal may be either a high frequency continuous waveform or high frequency burst packets. Other embodiments facilitate interconnection of the secure IO devices to a hardware security module or a personal computer while maintaining a high level of data security.
