  • Patent number: 9210768
    Abstract: Illumination techniques and related devices are disclosed. In some cases, a lighting device configured as described herein may include a front luminaire configured to emit white light and a back luminaire configured to emit colored light. The lighting device can be operatively coupled with controller circuitry programmed or otherwise configured, for example, with one or more algorithms which control the light output of the front and/or back luminaire so as to provide tunability. In some cases, device output may be controlled so as to: (1) simulate lighting conditions/patterns corresponding to the daytime/nighttime on Earth; (2) support/alter physiological processes; and/or (3) provide a specific ambient lighting for a given space. In some instances, a system of multiple such lighting devices can be provided, and in some cases, communication between constituent lighting devices may be provided. In some instances, the lighting device may be mountable as a sconce or other lighting fixture.

  • Patent number: 7715215
    Abstract: Control of an AC-to-DC power supply assembly fed by a three-phase AC source is provided by: determining whether the power supply assembly includes greater than three single-phase power regulators feeding a common load, with multiple regulators being connected in parallel across a common phase of the AC source, and if so, summing currents provided by the regulators to the common load; and ascertaining whether the summed current is less than a predefined threshold, and if yes, operating the power supply assembly in a line balance mode to maintain power drawn on the phases of the AC source in balance, and if greater than the predefined threshold, operating the power supply assembly in a maximize power mode wherein power is provided to the common load without maintaining power drawn on the phases of the AC source in balance.
