  • Publication number: 20230345855
    Abstract: System and methods for generating a work plan for a headland of an agricultural field (e.g., the portion of the agricultural field that is used by an agricultural machine to perform edge turns while working a main work partition of the field). A field boundary polygon indicative of a workable area of the agricultural field is segmented into multiple segments including a headland polygon and a work partition polygon. A seed track is generated based on a shape of a portion of the boundary of the headland polygon that is shared in common with the boundary of the field boundary polygon. The work plan is generated by replicating the seed track at a defined spacing throughout the headland polygon. In some implementations, the agricultural machine is operated autonomously or semi-autonomously to work the headland area based on the defined work plan.

  • Patent number: 11493426
    Abstract: 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.

  • Patent number: 11470766
    Abstract: 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.

  • Patent number: 11175254
    Abstract: A sensing system for obtaining a gradient of soil properties in real-time as a function of soil depth is disclosed herein. The sensing system includes a support structure coupled to an agricultural implement and which is rotatable about a rotational axis relative to a frame of the agricultural implement. A sensor is arranged on a surface of the support structure and configured to generate an output signal indicative of the measured soil property based on a sensed a capacitance change corresponding to a change in a dielectric property of a measured soil sample with which the sensor interacts. A measuring unit is coupled to the at least one sensor and processes the output signal generated by the at least one sensor to generate a gradient profile of the soil properties in real-time as a function of one or more depths for display on a user interface.

  • Patent number: 10670763
    Abstract: A sensor for determining soil properties is disclosed herein. The sensor includes a ground engaging structure adapted for coupling to an agricultural implement and to penetrate soil at a predetermined depth. An electrode assembly is disposed on a sensing surface of the ground engaging structure that includes a plurality of electrode sensing units. The plurality of electrode sensing units are configured to selectively generate a series of electric fields that project outwardly into the surrounding soil in response to receipt of an excitation signal and sense changes in the electric field corresponding to a change in a measured electrical output signal that is used to determine one or more soil properties during movement of the agricultural implement in a field.

    Abstract: A soil characteristic sensor is mounted on a soil engaging element of a planting machine. It can be mounted, for instance, on an element that engages the soil before a trench is opened, or after a trench is opened, but before it is closed. It can be mounted on an element that engages the soil in a region of the soil trench, but after the trench is closed. It can be mounted on a scraping element that scrapes a disc, and it can be mounted on wedges or other items that run through the soil, and are carried by shanks.
