A method of operating a lighting fixture comprising a plurality of discrete illumination sources of distinguishably different color coordinates comprises determining target color coordinates and luminous flux at which to operate the lighting fixture, determining input electrical power values for each of the plurality of discrete illumination sources that substantially produce the target color coordinates and luminous flux by referencing a calibration data lookup table having calibration data based on measurements of the plurality of discrete illumination sources, determining a color mixing zone defined by three distinguishably different color coordinates of the plurality of discrete illumination sources within which the target color coordinates lie according to the calibration data, determining luminous flux ratios for each of the plurality of discrete illumination sources having one of the three distinguishably different color coordinates defining the color mixing zone that substantially produces the target color coordinates, and determining input electrical power levels for each of the plurality of discrete illumination sources that generate the determined luminous flux ratios.

There is disclosed a process and apparatus for reading electrical current of electrodes on a microarray of electrodes. Those electrodes having binding events are detected by a difference in electrical current flow. Enzymes on targets catalyze the conversion of substrate to product, which is detectable by electrochemical reduction at each electrode on the microarray of electrodes. The apparatus has an integration circuit that provides a voltage output that is measured and recorded over time and used to calculate an average current flow. A potentiometer equalizes voltage at electrodes undergoing measurement compared to grounded electrodes.

Systems and methods for the transmission of auxiliary data via a modulated carrier signal superimposed on a primary data communication signal between terminals of a free-space optical communication system are disclosed. The carrier signal is modulated with an auxiliary data signal via phase-shift keying, amplitude-shift keying, frequency-shift keying, or other suitable modulation technique, and superimposed on the primary data communication signal prior to transmission as an optical signal by a transmitting free-space optical terminal. The primary data communication signal is received by at least one photo detector coupled to a receiving free-space optical terminal that demodulates the primary data communication signal to reconstruct the auxiliary data.
