A system and method in a network of devices, which ascertains the user’s context to suggest the most preferred task for the user to perform. The developing device includes a housing having an opening opposite the photoreceptor, a developing sleeve disposed inside the housing, a magnetic body disposed in a central portion of the developing sleeve and not in no-magnet portions thereof at both sides of the central portion, and seal members supported by the housing. The support structure may further comprise a worker platform to support a worker above the rig floor. The memory locations occupied by the one or more control blocks are determined and the contents of the memory locations are then copied to a target destination. The connection wires are arranged to overlap the bus bars and intersect the bus bars in the axial direction. The compliant handle is configured to frictionally engage a manipulation probe.
