摘要： A method includes receiving a measurement associated with a cloud point of a biofuel being produced in a refining system. The method also includes determining how to adjust the refining system based on a desired cloud point of the biofuel and the measurement associated with the cloud point. The method further includes outputting a control signal to adjust the refining system based on the determination. Determining how to adjust the refining system could include determining how to adjust an inlet temperature of a reactor in the refining system. The reactor could represent an isomerization reactor, and a heater could heat material entering the isomerization reactor. Determining how to adjust the inlet temperature of the reactor could include determining how to adjust operation of the heater. A model predictive control (MPC) technique could be used to determine how to adjust the inlet temperature of the isomerization reactor.

摘要： A spectroscopic sensor for measuring flat sheet product is disclosed. The disclosed sensor uses a combination of spectrometers and single-channel detectors and filters together with a broadband source of illumination to optimally measure multiple properties of a flat sheet product. A spectrometer is used to measure over a spectral range where an easily configurable set of wavelength channels is needed and where the signal-to-noise ratios and spectral resolutions of the channels are consistent with the spectral range and number of pixels of the spectrometer; while one or more single channel detector and filter combinations are used to measure, with high signal-to-noise ratio, at specific wavelengths within or outside the spectral range of the spectrometer(s). Therefore, the single channel detectors can be used to complement the information provided by a spectrometer or to extend the working range of a spectrometer by providing single wavelength measurements anywhere in the visible, near-IR or mid-IR spectral regions.

摘要： A method includes receiving at least one measurement of a dissolved carbon dioxide concentration of a mixture of fluid containing an autotrophic organism. The method also includes determining an adjustment to one or more manipulated variables using the at least one measurement. The method further includes generating one or more signals to modify the one or more manipulated variables based on the determined adjustment. The one or more manipulated variables could include a carbon dioxide flow rate, an air flow rate, a water temperature, and an agitation level for the mixture. At least one model relates the dissolved carbon dioxide concentration to one or more manipulated variables, and the adjustment could be determined by using the at least one model to drive the dissolved carbon dioxide concentration to at least one target that optimize a goal function. The goal function could be to optimize biomass growth rate, nutrient removal and/or lipid production.

摘要： A method includes measuring a caliper of a sheet of material using a caliper sensor having first and second sensor modules. The method also includes adjusting the caliper measurement based on a transverse displacement between a first sensor component in the first sensor module and a second sensor component in the second sensor module to generate a corrected caliper measurement. Adjusting the caliper measurement can include applying a corrector function that adjusts the caliper measurement based on the measured transverse displacement. The corrector function can be identified by repeatedly creating misalignment between the first and second sensor components, measuring a known distance using the caliper sensor, and identifying an error between the measurement of the known distance and the known distance.
