Abstract: A multi-tank spray system includes a first tank, a second tank, a pump, and a plurality of valves including a first valve, a second valve, and an equalizing valve. A first end of the first valve is in fluid communication with the first tank, a second end of the first valve is in fluid communication with (i) a first end of the equalizing valve and (ii) an inlet of the pump. A first end of the second value is in fluid communication with the second tank. A second end of the second valve is in fluid communication with a second end of the equalizing valve. A tank module is configured to receive a spray mode, receive a measurement from at least one sensor of a plurality sensors, and control operation of the plurality of valves and the pump based on (i) the received spray mode and (ii) the received measurement.

Abstract: A spray boom of a spray boom assembly includes a boom frame and a spray section coupled to the boom frame. The spray section includes an elongated spray pipe configured to be fluidly coupled to a fluid source and a nozzle coupled to the spray pipe. An actuator is coupled at one end to the boom frame and at an opposite end to the spray section. The actuator controllably extends and retracts to move the spray pipe and nozzle between a raised position and a lowered position.

Abstract: A feed control system for a spreader includes a section configuration module configured to output a section configuration and a section control module configured to receive the section configuration, determine a first actuator position based on the section configuration, and determine a second actuator position based on the section configuration. The feed control system also includes a belt speed module configured to receive the section configuration, receive a commanded belt speed, and determine a target belt speed based on (i) the section configuration and (ii) the commanded belt speed.

Abstract: An agricultural sprayer includes at least one nozzle configure to receive a fluid and direct atomized fluid to an agricultural surface in a dispersal area. A radio-frequency (RF) transmitter is disposed to generate an RF signal that passes through the dispersal area. The RF signal is detectably changed when interacting with droplets of the atomized fluid. A first RF receiver is disposed to receive the RF signal after the RF signal passes through the dispersal area and provides an output indicative of the RF signal. A controller is coupled to the first RF receiver and is configured to detect plugging of the at least one nozzle based on the output of the first RF receiver.

Abstract: An agricultural spreader includes at least one delivery conduit that carries material to be spread from a bin to an exit end of the delivery conduit under the influence of air blown through the delivery conduit by a fan. A deflector is mounted proximate the exit end of the delivery pipe and deflects the material onto agricultural field in a dispersal area. A radio frequency (RF) transmitter is disposed to generate an RF signal that passes through the dispersal area. The RF signal is detectably changed when interacting with the material passing through the dispersal area. An RF receiver is disposed to receive the RF signal after the RF signal passes through the dispersal area and provides an output indicative of the RF signal. A controller is coupled to RF receiver and detects plugging of the delivery conduit based on the output of the RF receiver.

Abstract: A mobile machine includes a sensor that generates a sensor signal indicative of ozone gas concentration. A power cable proximate the mobile machine, is identified based on the sensor signal. An avoidance action, is identified in response to determining that the power cable is proximate the mobile machine, and a control signal is generated based on the identified avoidance action.

Abstract: Wind speed, wind direction, and field boundary information are detected and used to identify a monitor area indicative of a likely overspray condition. Control signals are generated to obtain information from a sprayed substance sensor, in the monitor area. When an overspray condition is detected, an overspraying signal from the sprayed substance sensor indicating the detected overspray condition is received and overspray processing is performed, based upon the received overspray signal.

Abstract: An agricultural sprayer includes at least one nozzle configured to receive a liquid and direct atomized liquid to an agricultural field in a dispersal area. A thermal imager is operably coupled to the agricultural sprayer and has a field of view behind the agricultural sprayer. The thermal imager is configured to provide an indication of a thermal reaction of the agricultural field in response to application of the atomized liquid. An output of the thermal imager is used to characterize operation of the at least one nozzle.

Abstract: Wind speed, wind direction, and field boundary information are detected and used to identify a monitor area indicative of a likely overspray condition. Control signals are generated to deploy an unmanned aerial vehicle (UAV), with a sprayed substance sensor, to the monitor area. The UAV is controlled to reposition it, as a spraying machine moves through the field being sprayed. When an overspray condition is detected, an overspraying signal from the UAV indicating the detected overspray condition is received and overspray processing is performed, based upon the received overspray signal.
