In current transmitting methods, an instantaneous interruption of a transmission data may occur at the time of switching a system. Also described herein is a carrier medium carrying computer readable code configured to cause one or more processors of a processing system to implement the computer implemented method of determining a power planfrequency plan combination. Automated operation is enabled by a non-contact occupancy sensor and a flush sensor, both preferably built into a flush handle of the toilet. Once the connector body is fully seated, the locking cam cooperates with a locking tang on the retainer ring to hold the connector assembly together. An opposing set of brushes extends from the interior of the lower end into the chamber.
