Abstract: A multi-loop voltage regulator with load tracking compensation includes a first closed-loop feedback network configured to receive a supply voltage from a power supply and drive an output voltage that is smaller than the supply voltage to a load. The multi-loop voltage regulator includes a second closed-loop feedback network connected to the first closed-loop feedback network and configured to regulate the output voltage between a first supply voltage rail and a second supply voltage rail for a given load current, in which the second closed-loop feedback network produces a gain that is greater than that of the first closed-loop feedback network. The multi-loop voltage regulator also includes a load tracking compensation circuit configured to detect a load current, and to increase the gain of the second closed-loop feedback network based on a dominant pole in the second closed-loop feedback network being a function of the detected load current.

Abstract: A system can configure a luminaire for providing illumination of a selected color temperature, a selected lumen output, or a selected photometric distribution. The luminaire can comprise at least two light sources that have different illumination characteristics, for example different color temperatures, different lumen outputs, or different photometric distributions. The system can configure the luminaire to operate a first of the two light sources, a second of the two light sources, or both of the light sources based on an input. When the luminaire is configured to operate both of the light sources, the luminaire can produce illumination having a color temperature, a lumen output, or a photometric distribution that is different than either of the two light sources.

Abstract: The present disclosure relates to multiplex production and phenotyping of genetically engineered cells using RNA-guided nucleases and genomic barcoding. In particular, high-throughput multiplex genome editing is achieved utilizing a system that facilitates precise genome editing at desired target chromosomal loci by homology directed repair. Integration of guide RNA and donor DNA sequences as a genomic barcode at a separate chromosomal locus allows identification, isolation, and massively-parallel validation of individual variants from a pool of transformants. Strains can be arrayed according to their precise genetic modifications, as specified by donor DNA incorporation in heterologous or native genes.
