Patent number: 11647685Abstract: An automated implement control system includes one or more distance sensors configured for coupling with an agricultural implement. The one or more distance sensors are configured to measure a ground distance and a canopy distance from the one or more sensors to the ground and crop canopy, respectively. An implement control module is in communication with the one or more distance sensors. The implement control module controls movement of the agricultural implement. The implement control module includes a confidence module configured to determine a ground confidence value based on the measured ground distance and a canopy confidence value based on the measured canopy distance. A target selection module of the implement control module is configured to select one of the measured ground or canopy distances as a control basis for controlling movement of the agricultural implement based on the comparison of confidence values.Type: GrantFiled: October 13, 2022Date of Patent: May 16, 2023Assignee: Raven Industries, Inc.Inventors: Alex Weidenbach, John D.

Patent number: 11602142Abstract: A semi-active suspension system includes a suspension element having a damping coefficient range. The suspension element optionally includes an implement end and a chassis end. The semi-active suspension system includes a suspension control circuit in communication with the suspension element. The suspension control circuit optionally includes a kinematic assessment circuit in communication with one or more sensors. The kinematic assessment circuit is configured to measure or determine kinematic characteristics of one or more of the agricultural implement and the chassis. The suspension control circuit optionally includes a damping control circuit, and the damping control circuit generates a specified damping characteristic based on the measured or determined kinematic characteristics. The damping control circuit optionally directs the suspension element to operate within the damping coefficient range based on the specified damping characteristic.Type: GrantFiled: July 12, 2019Date of Patent: March 14, 2023Assignee: Raven Industries, Inc.Inventors: Alex Weidenbach, Jesse Lee Wagers, John D.
