The disclosure provides a method for orderly connection of a bluetooth headset controlled by a terminal. The structures project from the cylindrical shape of the drum cover that is mounted in the laundry drum. The transmission is operable to provide at least one reverse speed ratio and a plurality of forward speed ratios between the input member and the output member. Alternatively, the imaging transducer may be disposed within a removable transducer core adapted to fit within the tubular member.
