  • Publication number: 20230095578
    Abstract: Computer systems and methods of spatially-indexing agricultural content involve inputting agricultural content comprising spatial data and spatially-indexing the agricultural content by: identifying from the spatial data a set of geospatial boundaries for the agricultural content, indexing the agricultural content to the identified geospatial boundaries, cross-referencing the indexed agricultural data with a plurality of sets of geospatial boundaries for a plurality of fields, and indexing the agricultural content to one or more of the plurality of fields when the cross-referencing identifies an overlap between the geospatial boundaries of the indexed agricultural data and one or more of the geospatial boundaries of the plurality of fields.

  • Patent number: 11544296
    Abstract: Computer systems and methods of spatially-indexing agricultural content involve inputting agricultural content comprising spatial data and spatially-indexing the agricultural are disclosed herein. In an example, the computer systems and methods involve identifying from the spatial data a set of geospatial boundaries for the agricultural content. The computer systems and methods also involve indexing the agricultural content to the identified geospatial boundaries. The computer systems and methods further involve cross-referencing the indexed agricultural data with a plurality of sets of geospatial boundaries for a plurality of fields. The computer systems and methods additionally involve indexing the agricultural content to one or more of the plurality of fields when the cross-referencing identifies an overlap between the geospatial boundaries of the indexed agricultural data and one or more of the geospatial boundaries of the plurality of fields.

  • Patent number: 7885746
    Abstract: A transmission control system for a vehicle includes a first module that generates a first modified signal based on a first position of a driver input device and a second module that receives the first modified signal from the first module. The second module generates a second modified signal based on a second position of the driver input device and regulates operation of a transmission of the vehicle based on the first and second modified signals.

  • Patent number: 7600161
    Abstract: A method of verifying the integrity of an arithmetic logic unit (ALU) of a control module includes inputting a first test value into one of a plurality of registers of the ALU and inputting a second test value into remaining registers of the plurality of registers. A first set of operations is performed between the one of the plurality of registers and each of the remaining registers to produce a first set of results. A fault is indicated when one of the first set of results varies from a first predetermined result.

  • Patent number: 7343241
    Abstract: An engine start security control system for a vehicle having a transmission that is driven by an engine includes a first module that generates a first engine start flag based on an internal mode switch (IMS) signal and a second module that generates a second engine start flag based on a modified IMS signal. A third module selectively generates an engine start allow signal based on the first and second engine start flags.

  • Patent number: 6721643
    Abstract: A method is provided for controlling an output/input speed ratio of a continuously variable transmission (CVT) plant including primary and secondary pulleys actuated by primary and secondary pressures (Pp,Ps,), respectively, which generate forces to move the pulleys and adjust a corresponding belt, thereby adjusting the output/input ratio. The method includes calculating a desired force ratio for the CVT plant. Desired primary and secondary pressures (PP,PS) are then determined based, in part, upon the calculated desired force ratio, and the desired PS and PP signals are sent to the CVT plant to control operation of the CVT plant. An actual speed ratio is calculated based on measurements of input and output speed from the CVT plant.
