Abstract: A multifunctional device, such as a multifunction printer, enabling dynamic configurations of the icons on a graphical user interface. In some embodiments, the dynamic configurations create context specific icon layouts. Additionally, in some embodiments, a single icon button can be dynamically configured to represent a particular workflow operation conventionally requiring several inputs by a user at the graphical user interface. Specifically, the display of some embodiments can dynamically change to reflect the “next step” context within a workflow operation. Also, the display of some embodiments can dynamically change to reflect a unique user-context on the graphical user interface.

Abstract: An automatic depth adjusting control system and method for controlling the vertical position of a pair of corn detasseling devices adjustably mounted on a farm implement for removing tassels from two adjacent rows of corn plants. The control system includes a parallel link system for supporting the corn detasseling devices, a hydraulic cylinder connected to the parallel link system for controlling the vertical movement thereof to raise and lower the pair of corn detasseling devices, and a crop sensing unit positioned forwardly of each of the detasseling devices for detecting the height of the corn plants in a corresponding corn row. Each crop sensing unit provides for the transmission of either a raise signal or a lower signal, in response to the height of the corn plants in an associated row, to electrical circuitry and then hydraulic circuitry for actuating the hydraulic cylinder.

Abstract: A crop height sensing assembly for use in a control system that automatically adjusts the depth or vertical elevation of a mechanical corn detasseling device in response to the height of a corn plant having a tassel with adjacent leaf portions. The detasseling device is adjustably carried on a portable frame for movement along a corn plant row, and the control system includes a hydraulic cylinder assembly for raising and lowering the detasseling device, and circuitry for actuating the cylinder assembly. The crop sensing assembly includes a rock shaft extended tranversely of the portable frame, a support for the sensing assembly carried on the frame forwardly of the detasseling device for movement therewith, a plurality of dependent sensor rods axially spaced on the rock shaft and rockable therewith in response to contact with the corn plant leaf portions, and a signal assembly responsive to the rockable movement of the shaft to produce a sensing signal for operating the actuating circuitry.
