    摘要： The present disclosure relates to systems, devices, and methods for calibrating a light field projection system. One example system includes a projection unit operable to project a scanning sequence toward a screen having convex reflective elements. The scanning sequence is modulated according to a baseline intensity profile. The system also includes a calibration device disposed such that a portion of the scanning sequence is intercepted by the calibration device. The calibration device includes a first light detector arranged to detect an intercepted intensity profile. The calibration device also includes a second light detector arranged to detect a reflected portion of the scanning sequence as a measured intensity profile. The system further includes a control system. The control system is configured to determine an expected intensity profile and to modify operation of the light field projection system based on a comparison of the measured intensity profile to the expected intensity profile.

    摘要： Systems and methods relating to variable pressure turbines are disclosed. A power generation system may include a closed cycle system configured to generate power, a combustor, and a control system. The closed cycle system may include a working fluid circulating in a closed cycle path. The combustor may provide thermal energy to the working fluid. Further, the control system may be configured to determine to increase an amount of power generated by the closed cycle system, and in response to the determination to increase the amount of power generated by the closed cycle system, cause an increase in pressure of the working fluid in the closed cycle path.

    摘要： The present disclosure relates to methods for calibrating a light field projection system that includes a screen having convex reflective elements. One example method for calibrating a light field projection system includes scanning the plurality of convex reflective elements with light modulated according to a baseline intensity profile. The method also includes detecting a light intensity profile of the scanned light using a light detector at a first perspective. The method further includes comparing the detected light intensity profile to an expected light intensity profile and modifying operation of a control system that determines light field modulation schemes for projecting light fields to account for any differences between the detected intensity profile and the expected intensity profile. The detector may be moved to a second perspective and the previously steps of the method may be repeated from the second perspective of the light detector.

    摘要： Example methods and systems for determining failure modes of balloons within a balloon network are described. One example method includes: (a) determining at least one cohort balloon of a first balloon, where the first balloon is operating as part of a balloon network and where each cohort balloon shares at least one property with the first balloon, (b) determining at least one expected failure mode based at least in part on at least one failure of at least one cohort balloon, (c) determining a predicted failure mode of the first balloon based at least in part on the at least one expected failure mode, and (d) causing the first balloon to operate within the balloon network based at least in part on the predicted failure mode of the first balloon.
