Abstract: Methods, systems, devices and apparatus for implementing a custom color transition effect on at least one light-emitting fixture device are disclosed. In accordance with exemplary embodiments, a color step for implementing the color transition effect is computed (304) based on a frame rate of the light-emitting fixture device(s) so that pixels are updated on each frame according to the frame rate of the device(s). Computing and employing a color step in this way can be effective in lessening or eliminating perceptible discontinuities between pixels during a display of the color transition effect.

Abstract: An optical apparatus for measurement of industrial chemical processes. The analyzer uses Raman scattering and performs measurement of chemical concentrations in continuous or batch processes. The analyzer operates at a standoff distance from the analyte (or analytes) and can measure concentrations through an optical port, facilitating continuous, non-destructive, and non-invasive analysis without extracting the analyte or analytes from the process. The analyzer can measure one or several solid, liquid, or gaseous analytes, or a mixture thereof.
