The present invention is directed to sulfine control agents for synthesizing polymers via controlled free radical polymerization and to the polymers resulting therefrom. The method determines characteristics of the wireless transmissions used to communicate sensor andor actuator data to the control unit. At least one of the first version information and the second version information is used to determine a backward compatibility with respect to reading or writing of the recording medium. A conduit fluidly connects one pair of recessed seats to the tool exterior so as to port annulus pressure to the pressure-activated triggering mechanisms of the samplers. Meanwhile, when the need arises in the one of the sub-processors for a second image process related to the second task, the one of the sub-processor saves second rendering data for the second image process in a main memory.
