Abstract: A harvester is provided for harvesting a plant similar to or like sorghum having a stalk and a grain head. The harvester includes a combine vehicle, a lower row crop cutter mechanism, and an upper grain cutter mechanism. The lower row crop cutter mechanism is mounted to a connecting portion of the combine vehicle for cutting plant stalks at a lower end of the plant. The upper grain cutter mechanism is coupled to a lower section of the combine vehicle and is vertically displaced from the lower row crop cutter mechanism for cutting the grain head at upper end of the plant simultaneously with the cutting of the plant stalk by the lower row crop cutter mechanism.

Abstract: Methods and systems are provided for indicating whether an aircraft is below a designated minimum safe altitude level for an altitude sector. A method comprises displaying a graphical representation of a first sector on a display device associated with the aircraft. The first sector corresponds to a geographic area having a first minimum altitude criterion. If a current altitude of the aircraft is below the first minimum altitude criterion, the method continues by displaying the graphical representation of the first sector using a first visually distinguishing characteristic chosen to indicate that the aircraft is below the designated altitude level for the first sector.

Abstract: Methods and system are provided for alerting an aircraft crew member of a potential conflict between a first aircraft and a second aircraft on a first taxiway. Real-time positioning data related to the first aircraft on the first taxiway is monitored. Data related to real-time positioning of the second aircraft is monitored. A prediction is made as to whether the second aircraft will enter the first taxiway, based on the monitored data related to real-time positioning of the second aircraft. The potential conflict is indicated on the first taxiway, if a prediction is made that the second aircraft will enter the first taxiway.
