A connector is provided for coupling a member or a shelf to a support oriented in a substantially vertical direction. The terminal has means for receiving payment from a user, such as a check deposit module andor a cash receiving module. A compact climbing shrub growth habit is displayed. Thereby, it can be ensured that the pull-up node PU and the output terminal continue to be discharged, and thus the problem that the lifespan of the third thin-film transistor is affected by the frequent switching-on thereof can be solved. The analog subsystem calculates a difference signal and a sum signal based on the two RF signals. A sensor attached to either the fixed body, or to a hub spacer connected to the shank hub, automatically detects the presence of a user and activates the fluid dispensing system.
