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: Methods and apparatus, including computer program products, for interpolating low frame rate transmissions in lighting systems. A method (100) includes, in a microcontroller (22) of a light fixture (14), receiving (102) input data frames at a low frame rate from a light controller (12) over a data bus (16), generating (104) output data frames from any two adjacent input data frames according to a scaling scaling in a lookup table (LUT), and transmitting (106) the output data frames at a frame rate greater than the frame rate of the received input data frames to control a lighting effect of a light-emitting unit (24).

Abstract: A device (220) implements a method (600) of controlling dimming of a light emitting diode (LED) light source (230) by: receiving a phase-cut dimming signal (105) produced from an AC line voltage (15), ascertaining the peak voltage level (109) of the AC line voltage (15); ascertaining the present value of a phase-cut duty cycle of the phase-cut dimming signal, employing the peak voltage level of the AC line voltage to ascertain the maximum phase-cut duty cycle for the phase-cut dimming signal, ascertaining the phase-cut angle (107) of the phase-cut dimming signal from the present value of the phase-cut duty cycle of the phase-cut dimming signal and the maximum phase-cut duty cycle for the phase-cut dimming signal; and controlling the dimming of the LED light source in response to the phase-cut angle.

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.
