    摘要: A method of installing a releasable shade membrane to a shade system is presented. The method comprises installing a tension release system within a structural component of the shade system. The tension release system comprises a threaded member configured to, when actuated, cause a coupling mechanism to move along an axis defined by the threaded member. The method also comprises coupling a shade membrane to the coupling mechanism. The method also comprises actuating the threaded member in a first direction, such that the coupling mechanism moves along the axis in a tensioning direction. The tension release system is configured to release applied tension upon actuation of the threaded member in a second direction, causing the coupling mechanism to move along the axis in a release direction. The release direction is substantially the reverse direction of the tensioning direction.

    摘要: A mobile work machine includes a frame and a ground engaging element movably supported by the frame and driven by an engine to drive movement of the mobile work machine. The mobile work machine includes a movable element movably supported by the frame to move relative to the frame and an actuator coupled to the movable element to controllably drive movement of the movable element. The mobile work machine includes a sensor that detects an operation characteristic and generates a sensor signal, indicative of the operation characteristic and a grade control system that receives the sensor signal from the sensor and determines a spillage metric, based on the sensor signal. The mobile work machine also includes a control system that generates an actuator control signal based on the spillage metric. The control signal is indicative of a commanded movement of the actuator. The control system controls the actuator to perform the commanded movement.

    摘要: A colorimetric analyzer includes a reaction chamber configured to receive a sample and at least one reagent. A measurement cell is operably coupled to the reaction chamber. The measurement cell has an illumination source and an illumination detector spaced from the illumination source such that illumination from the illumination source passes through the measurement cell to the illumination detector. A controller is coupled to the illumination source and the illumination detector. The controller is configured to determine an absorbance of a reducing reagent and store the determined reagent absorbance in the analyzer. The controller is configured to use the determined reagent absorbance to compensate at least one subsequent colorimetric sample measurement.
