  • Patent number: 11759805
    Abstract: The invention relates to an active substance supply system for an agricultural sprayer, having a main liquid circuit which comprises a reservoir for a main liquid and permits circulation of the main liquid, where the main liquid circuit comprises one or more distribution sections which are each configured to distribute to several dispensing elements a spray liquid to be dispensed, and a feed system which is connected to the main liquid circuit and in which the main liquid is mixed with at least one separately supplied active substance to form a liquid active substance mixture, where the active substance supply system is configured to introduce the active substance mixture into the one or more distribution sections at several places.
    Type: Grant

  • Patent number: 11235345
    Abstract: A system and method for dispersing fluids from an agricultural vehicle includes a sprayer that dispenses the fluids and a controller cooperative with a plurality of sensors to sense vehicle travel speed, vehicle travel direction, wind speed, wind direction, and the heights of first and second nozzles from the ground surface. The controller includes a memory storing a look-up table having fan angles of the first and second nozzles, and a processor that computes first and second spray pattern on the ground surface based on the fluid dispensed through the respective first and second nozzles. The processor determines an overlap region between the first and second spray patterns, compares the determined overlap region with a pre-determined overlap, and takes corrective action automatically by changing travel speed of the vehicle or changing a duration of time the fluids are dispensed from the first and second nozzles.

  • Patent number: 10241209
    Abstract: An arrangement for detecting the position of a handset comprises a vehicle having a positioning signal receiver for receiving signals of the satellites of a positioning system and an electronic processor. The processor generates a local correction signal to improve the accuracy of a position determined by the signals of a positioning signal receiver. A portable handset is equipped with a positioning signal receiver for receiving signals of the satellites of the positioning system and an electronic processor which, in operation, receives position signals from the positioning signal receiver of the handset, derives from these signals raw position data of the handset and uses these raw position data for determining the position of the handset. The raw position data of the handset are corrected by the local correction signal provided by the processor of the vehicle.
