Publication number: 20230345859Abstract: An agricultural machine may include a first plurality of sensors configured to measure characteristics of product stored on the machine for use during the machine's operation. The machine may also include a second plurality of sensors configured to measure characteristics associated with operation of the machine, in particular, in the form of feedback from ground engaging mechanisms of the machine, such as row units and wheel assemblies coupled to a frame of the machine. Based on the measured characteristics of the stored product and the measured characteristics associated with the machine's operation, a controller may adjust actuators coupled between adjacent sections of the frame to transfer weight of the stored product between certain sections of the frame, which in turn optimizes the machine's operational characteristics.Type: ApplicationFiled: April 28, 2022Publication date: November 2, 2023Inventors: Gerald E. Rains, Bin Shi, Kevin P. Cowles, Jason D. Walter, Shawn A. Kenny, Olaf J. Peterson

Patent number: 11493426Abstract: An object counting device adjusts a signal to account for noise to improve object counting accuracy. A controller receives an electromagnetic radiation (e.g., light) intensity signal from radiation detectors and determines that its value is within a voltage threshold, thereby indicating that no object is passing through the radiation. The controller determines a derivative of the signal and that the derivative is less than a derivative threshold level for at least a predefined time. The controller then updates a base noise floor value to be the value of the radiation intensity signal to account for particles within a path of the electromagnetic radiation to improve an object counting accuracy. In some embodiments, the processor can scale the received radiation intensity signal in accordance with the updated base noise floor value.Type: GrantFiled: July 31, 2020Date of Patent: November 8, 2022Assignee: DEERE & COMPANYInventors: Haifeng Zhang, Ryan J. King, Kevin P. Cowles, Jason A. Jelinek, Waylon R. Lindseth, Caleb A. Perkinson, Jeffrey S. Puhalla

Patent number: 11470766Abstract: An object detection system compensates for variations in transmission characteristics within an object passageway caused by, for example, dust or dirt. An object detection device includes a plurality of electromagnetic radiation emitters and detectors arranged in rows on opposite sides of a passageway. First lenses focus radiation from the emitters into a semi-columnated beams of radiation that together create a plane of semi-columnated electromagnetic radiation that spans substantially across a width of the passageway. Second lenses focus the received electromagnetic radiation onto corresponding ones of the plurality of radiation detectors. A controller receives a radiation intensity signal from the detectors, determines that its value is outside of a predetermined range, and adjusts an amount of electrical power supplied to the plurality of radiation emitters so that the value of the radiation intensity signal changes to become within the predetermined range.Type: GrantFiled: July 31, 2020Date of Patent: October 18, 2022Assignee: DEERE & COMPANYInventors: Ryan J. King, Kevin P. Cowles, Jason A. Jelinek, Waylon R. Lindseth, Haifeng Zhang, Caleb A. Perkinson, Jeffrey S. Puhalla

Patent number: 11029275Abstract: A first conductor is embedded in the first dielectric layer to a first wear depth, where the first wear depth is associated with a first threshold wear level. A second dielectric layer overlies the first dielectric layer to a second wear depth. The second wear depth is associated with a second threshold wear level greater than the first threshold wear level. A second conductor is embedded in the second dielectric layer and separate from the first conductor. An indicator is adapted to indicate whether the wear plate is the first threshold wear level or the second threshold wear level.Type: GrantFiled: October 19, 2018Date of Patent: June 8, 2021Assignee: DEERE & COMPANYInventors: Michael L.
