Systems and methods for mapping the distribution of residue material in an environment in which one or more agricultural machines are operable. A sensing arrangement having one or more sensors mounted or otherwise coupled to an agricultural machine operating within the environment is used to obtain sensor data indicative of residue material spread by a spreader tool of the agricultural machine. From this a local distribution of residue material associated with the spreader tool is determined which is used to update a map of a global distribution of the residue material across the environment. The map comprises a grid-based map having a plurality of cells corresponding to sub-regions within the environment, wherein a value associated with each cell is representative of a measure of the residue material present within the corresponding sub-region.

One apparatus for providing high-resolution CSI feedback includes a processor and a radio transceiver. The processor computes sets of amplitude and phase parameters for one or more channel compression matrices. Here, each channel compression matrix corresponds to one transmission layer of a multiple-layer transmission, where each channel compression matrix is comprised of one or more column vectors. The radio transceiver sends indications of the sets of amplitude and phase parameters to one or more network entities is a mobile communication network.

A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.

A field shape identification unit in a server control unit identifies, on the basis of position information about a work vehicle, the shape of a work field through which the work vehicle has traveled while working. A degree-of-overlap determination unit in the server control unit compares the shape of the work field identified by the field shape identification unit to the shape of a reference field and determines whether the degree of overlap between the work field and the reference field is greater than or equal to a prescribed degree. When the degree-of-overlap determination unit determines that the degree of overlap between the work field and the reference field is equal to or greater than a prescribed degree, an information management unit associates work-related information pertaining to the work in the work field with the reference field and manages the same.

Systems, methods, and apparatuses for emitting light from a header reel are disclosed. More particularly, systems, methods, and apparatuses for emitting light at one or more locations along a bat tube of a header reel are disclosed. In some instances, a light source may be provided on the bat tube between adjacent reel fingers coupled to the bat tube. In some instances, the light source may be provided at an aperture formed in the bat tube. The emitted light provides for illumination and operator visualization during, for example, agricultural operations performed at night or during low ambient light conditions.

Systems, methods, and apparatuses for emitting light from a header reel are disclosed. More particularly, systems, methods, and apparatuses for selectively emitting light from different portions of a reel header are disclosed. In some implementations, light is selectively emitted from different parts of a reel header based on a position of the reel header. For example, light may be emitted based on a position of the portion of the reel header as the reel header is rotated. The emitted light provides for illumination and operator visualization during, for example, agricultural operations performed at night or during low ambient light conditions.
