Patent number: 11946747Abstract: One or more maps are obtained by an agricultural work machine. The one or more maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.Type: GrantFiled: October 9, 2020Date of Patent: April 2, 2024Assignee: Deere & CompanyInventors: Nathan R Vandike, Noel W. Anderson, Bhanu Kiran Reddy Palla, Nathan Greuel, Alexander B. Lassers

Patent number: 11653596Abstract: A dynamic event detection system detects dynamic events, based on a sensor signal, on a mobile harvester. A dynamic event correction system identifies a correction magnitude, corresponding to the detected dynamic event, and a correction timing. The dynamic event correction system applies a correction, using the correction magnitude and correction timing, to a performance metric value generated from a performance metric sensor.Type: GrantFiled: December 18, 2019Date of Patent: May 23, 2023Assignee: Deere & CompanyInventors: Michael S. Garton, Alexander B. Lassers

Patent number: 11553648Abstract: A row unit assembly for use with a corn harvester includes a first drive having an output shaft, a stalk roll that extends along a first axis and rotates about the first axis via the output shaft of the first drive. A second drive rotates a first drive member about a second axis that is substantially perpendicular to the first axis. A first conveyor extends around the first drive member and moves about the first drive member in response to rotation of the first drive member. A third drive rotates a second drive member about a third axis that is substantially parallel to the second axis. A second conveyor extends around the second drive member and moves about the second drive member in response to rotation of the second drive member.Type: GrantFiled: April 29, 2019Date of Patent: January 17, 2023Assignee: Deere and CompanyInventors: Nathan E. Krehbiel, Nathaniel R. Bernklau, Nathan R. Vandike, Austin M. Laugen, Alexander B. Lassers

Publication number: 20220132736Abstract: Embodiments of a kernel-level grain monitoring system include a grain camera positioned to capture bulk grain sample images of a currently-harvested grain taken into and processed by a combine harvester, a moisture sensor, and a display device. A controller architecture is coupled to the grain camera, to the moisture sensor, and to the display device. The controller architecture is configured to: (i) analyze the bulk grain sample images, as received from the grain camera, to determine an average per kernel (APK) volume representing an estimated volume of a single average kernel of the currently-harvested grain; (ii) repeatedly calculate one or more topline harvesting parameters based, at least in part, on the determined APK volume and the moisture sensor data; and (iii) selectively present the topline harvesting parameters on the display device for viewing by an operator of the combine harvester.Type: ApplicationFiled: November 3, 2020Publication date: May 5, 2022Inventors: Zachary A. Meyers, Stephen R. Corban, Jeremiah K. Johnson, Alexander B. Lassers

Patent number: 11160208Abstract: A sensing system and method is provided for crop material in a harvester. The sensing system includes a conveyor auger device oriented in a substantially vertical direction and having an entrance aperture, an exit aperture located upwardly above a radially oriented sensing aperture disposed therebetween. The conveyor auger device includes a conveyor auger having a flight for moving crop material upwardly, wherein the flight has a reduced radial extension adjacent the sensing aperture. A sensor disposed at or adjacent the sensing aperture senses the essentially continuously upwardly moving crop material for determining a property thereof.Type: GrantFiled: April 29, 2019Date of Patent: November 2, 2021Assignee: DEERE & COMPANYInventors: Douglas G. Temple, Alexander B. Lassers, Nithin Choudary

Publication number: 20210321568Abstract: A belt load characterization system receives a belt slip detector signal indicative of belt slip, and identifies, in near real-time, a severity level and impact of the belt load characteristics. A notification system generates an operator interface mechanism control signal to surface a notification to the operator indicative of the belt load characteristics, and the severity level and impact of those characteristics. The machine can be controlled based on the belt load as well.Type: ApplicationFiled: April 16, 2020Publication date: October 21, 2021Inventors: Michael S. Garton, Alexander B. Lassers
