  • Patent number: 10138618
    Abstract: An excavator comprises a control architecture having one or more linkage assembly actuators and one or more controllers. The one or more controllers are programmed to execute instructions. The instructions determine if there is a request to operate the excavator boom and the excavating implement in automatics mode. The instructions also receive target design surface data representing a target design surface of an excavating operation. The instructions further receive an implement position representing a position of the excavating implement relative to the target design surface. The instructions still further receive an implement angle representing an operating angle of the excavating implement relative to the target design surface.

    Abstract: The seed distribution tower of an air seeder splits a single, primary stream of conveying air and seeds into a plurality of secondary streams for delivery to openers that deposit the seeds into the ground as the seeder advances. As seeds enter the head of the tower in an upward vertical direction through an inlet at the bottom of the head, they are scattered 360° in a horizontal direction by an inverted, overhead distribution cone. The inlet through which the seeds enter the distribution head has an eased configuration to reduce turbulence and promote laminar flow within the head during the dramatic transition from vertical to horizontal movement. Sensitive components such as tram line valves, solenoid actuators, and blockage sensors are protectively housed within the interior of the distribution head to avoid exposure to hostile environmental elements.

  • Patent number: 7525443
    Abstract: A method for determining a steady state operating condition of a machine includes determining whether a current machine speed of the machine is within a defined range of operation, determining whether a step change in output power of the machine has occurred, determining a first duration of time elapsed since the machine speed was last outside of the defined range of operation, and determining a second duration of time elapsed since a most recent detected step change in output power of the machine. The machine is deemed to be in a steady state condition whenever the current machine speed of the machine is within said defined range of operation, and the first and second durations of time exceed respective minimum values defined therefor.

  • Patent number: 7450019
    Abstract: An output monitoring system and method for an air transport material delivery system that directs dry material entrained in pressurized air out of delivery tubes and against an inner surface of deflectors for even distribution. The output monitoring system has a plurality of sensors respectively affixed to the deflectors on the outer side thereof so as not to be directly contacted by the stream of air and dry material impacting the inner side. Each sensor generates a voltage which is indicative of the flowing or clogged condition of its corresponding delivery tube. This status information is dynamically provided to a display unit where it can be readily monitored by the operator of the air transport material delivery system during operation thereof to ensure that the delivery tubes are not blocked or, if a blockage occurs, that operation of the air transport material delivery system is suspended until the blockage is removed.

  • Patent number: 7391338
    Abstract: Apparatus and method is provided for using low cost, passive RF sensor technology such as RFID tags, to determine whether containers or other objects are in a right-side-up orientation. A useful embodiment of the invention is directed to sensor apparatus for use in detecting an improper orientation of a conventional box or container with respect to a substantially horizontal surface. The apparatus includes a structure having two sides formed of plastic in spaced apart relationship, to define an enclosed space within the structure. Selected shielding material attached to the structure shields a specified region of the enclosed space against RF signals, the shielded region being located in the lowest portion of the enclosed space when the structure is in a reference orientation with respect to the horizontal surface. An RFID tag embedded in a disk is positioned in the enclosed space, the disk being sized to move freely within the space.

  • Patent number: 7295895
    Abstract: A method of measuring the quantity of wrap remaining on a round baler supply roll uses the existing wrap measuring apparatus of a round baler. An on-board microprocessor is programmed to calculate the minimum amount of wrap required for each bale, subtract the amount of wrap used to wrap a bale from the amount of wrap on the supply roll before wrapping the bale, and signal the operator if the amount on the roll is insufficient to wrap a bale. The microprocessor can also be programmed to signal the operator if the amount of wrap on the roll is insufficient to wrap a number of bales specified by the operator.

  • Patent number: 7154385
    Abstract: A vehicle-trailer back-up control system that employs an active front steer sub-system. The system includes a smart hitch controller that receives a vehicle speed signal and a hand-wheel angle signal, and calculates a hitch angle command signal. The system further includes a hitch angle sensor that measures the hitch angle between the vehicle and the trailer that is compared to the hitch angle command signal to generate a hitch angle error signal. A PID control unit receives the hitch angle error signal, and generates a corrected road wheel angle signal based on proportional and derivative gains. The corrected road wheel angle signal is used to generate a motor angle signal that is applied to a steering actuator to be combined with the steering angle signal to generate the front wheel steering signal during a back-up maneuver.

  • Patent number: 7034666
    Abstract: A communication device is provided which is intended to aid farm workers in the coordination of harvesting and hauling vehicles in the field during crop harvesting operations. This communication device consists of a transmitter and receiver which are mounted at convenient points within the harvesting vehicle and produce hauling truck respectively. The receiver contains four lighted directional arrows representing directional changes of forwards, backwards, left, and right. The transmitter contains four buttons that correspond in location and function to the directional arrows on the receiver. Thus, when a button on the transmitter is depressed by the harvester operator, the corresponding directional arrow on the receiver will light up signaling the truck driver to make a change in the position of his truck relative to the harvester.
