Abstract: An agricultural machine system, includes: an agricultural machine; a control system operatively coupled with the agricultural machine, the control system including: a sensor configured for: sensing a cut stubble of a plant material; outputting a cut stubble signal corresponding to the cut stubble; a controller system operatively coupled with the sensor and configured for: receiving the cut stubble signal; determining a cut stubble characteristic based at least in part on the cut stubble signal; outputting an output signal based at least in part on the cut stubble characteristic.

Abstract: Temporarily limiting access to a storage device, including: determining that a storage device of a plurality of storage devices in a storage system is operating outside of a defined performance range; determining that the storage device operating outside of the defined performance range may be caused by a rehabilitative action performed on the storage device; and modifying a storage operation issuance policy for one or more storage devices of the plurality of storage devices until a determination that the storage device is operating within the defined performance range.

Abstract: An engine has a controller for causing an EGR system to disallow EGR while concurrently executing a strategy for evaluating calibration of a mass airflow sensor in an intake system by operating the engine at each of different combinations of engine speed and engine load, and for each combination of engine speed and engine load, recording a corresponding output signal of the sensor and also calculating mass flow passing through an intake manifold as a function of intake manifold pressure, intake manifold temperature, speed of the engine, and volumetric efficiency of the engine. The output signal of the MAF sensor and the calculated mass flow passing through the intake manifold at least one combination of engine speed and engine load are used to evaluate the calibration the MAF sensor.
