Abstract: An irrigation system broadly comprising a number of irrigation spans and a control system configured to operate single speed drive motors of the irrigation spans in a start-up mode, full speed mode, and wind-down mode. In the start-up mode, the motor controller gradually increases the drive motor speed from 0 rpms to a full speed by ramping a voltage applied to the drive motor from a starting voltage to a full speed voltage according to a start-up voltage profile over a start-up time interval. In the full speed mode, the motor controller operates the drive motor at a full speed voltage. In the wind-down mode, the motor controller gradually decreases the drive motor speed from full speed to 0 rpms by ramping the voltage applied to the drive motor from the full speed voltage to an ending voltage according to a wind-down voltage profile over a wind-down time interval.

Abstract: Implant inserters and related methods are disclosed herein, e.g., for delivering a fusion cage or other implant to a spinal disc space and for rotating or articulating the implant within the disc space. An exemplary instrument can include an inner member having opposed jaws for grasping the implant and holding the implant during insertion. The inner member can be slidably received within an outer member such that relative axial translation of the inner and outer members is effective to open or close the jaws. The jaws and/or the distal end of the outer member can have a low-profile geometry, which can advantageously facilitate certain surgical procedures. For example, the low-profile geometry can allow for a more medial approach to an intervertebral disc space in which the implant is to be inserted.

Abstract: A lateral move irrigation system more effectively irrigates a field by minimizing the portions of the field that receive no irrigation. The irrigation system includes a plurality of mobile towers, a plurality of elongated support structures attached to and extending between the towers, and a fluid delivery system. Each mobile tower has wheels and a motor for driving the wheels. A safety circuit stops the motors on all the mobile towers when any of the towers reaches an end-of-run position. Location determining components determine locations of the mobile towers as they traverse a field, and a control system stops or slows any of the towers before they trigger the safety circuit so that lagging mobile tower may catch up before the safety circuit shuts down or reverses all the motors.
