A system for scheduling cleaning of an ink jet print head loaded in an ink jet printer. The electronic building system controller extracts information from the static visual code and reconfigures internal programming responsive to extracting the information. This process alleviates a problem with simpler approaches which merely require operator authorization to associate auxiliary RFID wristbands with primary RFID wristbands. The longitudinal axes can be oriented by movement of the linkage arm about the first lateral axis andor the second lateral axis. The elastomeric body includes a main seal lip configured to engage the outer running surface of the inner wear sleeve and a plurality of thrust pads extending axially from the rim for engagement with the flange. Among the MOS FETs included in the logic circuit, those other than a MOS FET for supplying electric charges via an output terminal have threshold voltage values lower than the threshold voltage value of the MOS FET for supplying electric charges.
