Abstract: An operator interface for a control system for a bulk material baler includes interface means such as a touch screen or keyboard for an operator to enter process parameters into a control system memory. A display shows process parameter fields into which an operator may enter desired control parameters. The display also displays data feedback from baler process sensors. The baler control system then controls baling parameters as the operator directs including: strap feed position, strap feed speed, strap feed torque, strap release tension, tying cylinder position, tying cylinder speed and tying cylinder torque. The operator may also control carriage movement, alarm limits, shut off limits and monitor on the display baler processing data both currently and historically. Other aspects of automated baling may be optionally monitored or controlled through the operator interface of the present invention.

Abstract: A lumbar support device includes a flexible grid that can be bowed to provide additional curvature and axially moved on a track. The flexible grid is bowed and moved by brackets on the track in combination with cables and actuators. For bowing the flexible grid, a cable segment pulls a pair of brackets together which bow the flexible grid. The segment is wrapped around one of the brackets and is attached at its ends to the other bracket and an actuator, thereby providing a mechanical advantage to the bowing resistance of the flexible grid. For axially moving the flexible grid, a cable in a fixed bracket directly pulls on the pair of brackets and the flexible grid moves with the pair of brackets; a compression spring is used to provide resistance to the cable and movement in an opposite direction. In another embodiment, a lumbar support device includes a flexible grid that is bowed without any change in axial position.
