Patent number: 11790539Abstract: Methods, apparatus, and systems for sensing or tracking relative position between objects or locations. A digital camera or imager captures one or more fiducials in its field of view. By calibration and processing, the imaged fiducials can be identified and distinguished from other objects and background in camera space, and position of imaged fiducials in camera space relative to a reference can be translated to position of the actual fiducials in physical space. In one example, the fiducials are IR LEDs.Type: GrantFiled: March 24, 2022Date of Patent: October 17, 2023Assignee: Ag Leader Technology, Inc.Inventor: Trenton Anagnostopoulos

Patent number: 10123472Abstract: Systems, apparatus, and methods for informing an on-tractor navigation system of position of a towed implement. In one aspect, a non-GNSS sensor mounted on the implement provides heading information to the navigation system. Knowledge of the geometry of the implement along with navigation coordinate frame position information from the navigation system, allows a relatively economical and flexible way to derive implement position information without the expense of a GNSS receiver on the implement Adding inertial sensors on the implement can allow position determination of any point on the implement relative to the ground. This can be advantageously used for swath and rate control for implements.Type: GrantFiled: July 1, 2016Date of Patent: November 13, 2018Assignee: Ag Leader Technology, Inc.Inventor: Michael Schneider

Patent number: 10024459Abstract: Methods, apparatus, and systems providing enhanced feed rate control of tubing and conduit feeds by a powered feeder to an in-ground placement device moved across the ground by a steerable vehicle. In one aspect, ground speed of the vehicle is sensed. Feed motor speed is correlated to length of tubing or conduit estimated to be fed per feed wheel revolution by the feed motor. A controller adjusts feed motor speed to match ground speed to feed rate. In another aspect, instead of estimating feed rate by feed wheel rotation, actual speed of movement of the tubing or conduit is sensed. Feed motor speed is automatically and dynamically adjusted to match ground speed to tubing or conduit speed. In either embodiment, sensing of ground speed can be used to sense starting and stopping of the vehicle. This can be used to turn the feed motor on or off. In either embodiment, integration with a precision agriculture intelligent controller can allow operator control right from the precision ag display.Type: GrantFiled: April 4, 2016Date of Patent: July 17, 2018Assignee: Ag Leader Technology, Inc.Inventors: Aaron Friedlein, Ronald L. Farrington, Corey Weddle

Patent number: 9756774Abstract: A system, method, and apparatus for automatically gathering seed-specific data for an agricultural crop. Simulated seeds with contactless machine-readable data are co-mingled with actual seeds. Whether in stored form prior to planting, during planting, or after planting with the actual seed in the ground, appropriate readers can quickly and accurately read the seed-specific data for a variety of purposes. That can include simply confirming that the actual seed at least in proximity to a simulated seed is of a particular hybrid or variety. It could also include other seed-specific data such as time and date of planning, seed production company, seed-specific usage restrictions, etc. The data can be utilized by other systems. One example would be a precision agricultural system.Type: GrantFiled: January 15, 2016Date of Patent: September 12, 2017Assignee: Ag Leader Technology, Inc.Inventor: David Wilson
