First and second attachment portions 6, 8 are formed integrally with a main body 4 and extend along the longitudinal direction of the main body 4. The endless belt conveying surface is supported by the frame. In a second aspect, the controller performs soft decoding using the generated soft-decision metrics. The operations can further include determining a selection purpose for the selection, determining transference instructions for an item representation of the selectable object, and transferring the item representation to a second area of the gaming display that is under control of a second application module. With the clutch in the \u201con\u201d position and with the bail system closed, the rotor assembly can only be rotated in the line retrieving direction. A first controller for the first inverter uses a dc link voltage demand signal indicative of a desired dc link voltage to control the first inverter switches to achieve a desired dc link voltage level.
