摘要： A control system is provided for efficiently regulating the discharge of material from a mobile material distribution device having a product tank or bin, a boom with at least one boom section, a plurality of outlet ducts (e.g., nozzles and/or distribution ports) associated with each boom section, shut-off valves for selectively enabling each boom section, and a selectively-movable control valve for regulating the flow of material to the boom sections. The control system includes a boom sensing input for monitoring whether the shut-off valves are open or closed (i.e., whether the associated boom sections are enabled or disabled), and a processing system for maintaining a substantially stable pressure level between the control valve and each shutoff valve by positionally locking the control valve at its last controlled position upon receiving a signal from the boom sensing input indicating the shut-off valves are closed. Based information received from the boom sensing input, other feedback sensors, and/or manually entered by the user, the processing system selectively regulates the control valve of the material distribution device so as to precisely regulate the material dispersal rate through the enabled boom sections and to provide the material distribution device with certain useful functions including loading, unloading, and agitation features.

摘要： A selective spraying weed control system utilizes weed detectors that identify weeds in a field of view and releases herbicide from individual nozzles. The timing of the release of herbicide from each nozzle is controlled to correspond to the actual ground speed of each nozzle. Such actual ground speed is extrapolated from direct measurements of ground speed taken from two separate locations in the weed spraying apparatus, and from the location of each nozzle within the apparatus.

摘要： A granular and liquid material spreading system mounted on a vehicle. Granular material is moved from a hopper to a delivery system using hydraulic pumps and motors. The hydraulic system also drives a liquid delivery system. A control system including a material computer is provided to control the amount of granular material and liquid material applied to a surface. The feed rate of liquid delivery is controlled electronically by programming the material computer as a function of the feed rate of the granular material. The liquid feed rate may be changed within a predetermined range. The level of liquid may be sensed to disengaged the liquid delivery system. Initiation of liquid delivery reduces the feed rate of granular material by a variably selected percentage.

摘要： A control system for providing uniform spraying of plants and for spraying only areas containing plants. A plurality of plant sensors each detect the presence or absence of plants in a narrow field of view and cause spray nozzles to provide a spray solution to only areas containing plants. A ground speed sensor causes the volume of spray solution to be adjusted to provide a predetermined density of coverage of plants irrespective of the ground speed of a sprayer.

摘要： A windshield washer control for a vehicle is responsive to vehicle speed to vary the speed of an electric motor driven pump so as to vary the pump pressure with vehicle speed and thus counteract the downward dislocating effect, increasing with vehicle speed, of air rushing over the windshield, whereby the cleaning fluid is applied to a predetermined target area of the windshield regardless of varying vehicle speed. In addition, the pump may be activated for a time varying inversely with vehicle speed to counteract the variation of volume flow with varying pump pressure and thus cause a substantially constant volume of cleaning fluid to be applied to the windshield for each activation of the pump.

摘要： A fluid delivery system (10) is provided for delivering at least one chemical (26) onto a field in a desired concentration. A carrier fluid (67) is provided for diluting the farm chemical (26). The mixture is pumped through a spray boom (18) onto the field by a main fluid pump (74). The chemical (26) is delivered to the inlet port (76) of the main fluid pump (74) by a chemical pump (54). The chemical pump (54) is operated by a variable speed stepping motor (56). The speed of the stepping motor (56) is controlled by a speed sensing wheel (88) to provide a uniform concentration of chemical on the field independent of vehicle speed. The motor speed is also controlled by a thumbwheel switch (116) to deliver a desired concentration on the field compensating for drive vehicle wheel slippage. The motor speed is also adjusted to calibrate the delivery concentration to the nozzle pattern through calibration switches.

摘要： A spray unit and process for controlled droplet atomization in which a tangential vortex type fan with wide mouth passes operation from low-to-medium pressures at high volume, passes air through a throat in which controlled droplet atomization of spray material is being achieved prior to emission from the fan in a plane generally parallel to the flow of air. The flow of air sweeps the droplets into a parallel orientation in substantial avoidance of contact of the spray material on the fan parts, throat or mouth thereof and the airflow confines the continuous core of controlled droplets and projects the protected spray toward a target. The spray units are arranged to permit plural end-to-end adjacent articulated mounting with directional adjustment and flexible conduits for power at the individual units, including spray material delivery and power to lineal actuators and are carriage mounted on wheels for easy movement in the target area.
