Abstract: The present disclosure provides systems for generating tunable white light. The systems include a plurality of LED strings that generate light with color points that fall within red, blue, and green color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output. The systems can include an additional LED string configured for functional applications that includes a type of LED selected from 380-420 nm violet saturated LEDs, 200-280 nm UVC saturated LEDs, 850-940 nm near-IR saturated LEDs, 580-620 nm amber-orange/red saturated LEDs, and 460-490 nm long-blue saturated LEDs.

Abstract: A kit for joining together at least a pair of light fixture segments at a joint interface therebetween to form a light fixture assembly, comprises at least a pair of complementary coupling units, each coupling unit configured to be located in an operative position in one of said light fixture segments to join the other coupling unit at the joint interface defined by complementary abutment surfaces on said light fixture segments, at least one of the complementary coupling units being configured to be adjustably located in the operative position to displace another of the coupling units along a designated travel path toward a limit position, wherein the joining of the light fixture segments at the joint interface occurs in advance of the other coupling unit reaching the limit position.

Abstract: Methods are provided for the automated detection of assay-positive assay areas in a microfluidic device. When assays are performed in a microfluidic device, the configuration of the microfluidic circuit and its constituent circuit elements can determine where the reagents/analytes used in the assay can be located within the microfluidic circuit. Methods are provided for automatic identification of the size and shape of the assay areas based on a number of parameters which may include type of assay involved, shape and dimensions of microfluidic circuit elements, velocity and physical characteristics of the fluidic medium within the microfluidic circuit, physical/chemical properties of the analytes/reagents, and/or the number of cells being assayed.
