  • Publication number: 20170330492
    Abstract: An illuminated sign comprises a source of blue light; a quantum dot-containing film that produces green light when illuminated by the source of blue light; and, a patterned blue cutoff filter in optical communication with the quantum dot-containing film configured to allow a mixture of excess blue light from the source of blue light and green light from the quantum dot-containing film to pass through the pattern. The mixture of blue light and green light produces a pseudo white light. The illuminated sign may thus comprise pseudo white letters and/or graphics on a luminous green background.

  • Patent number: 9795016
    Abstract: The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices.

  • Publication number: 20170233690
    Abstract: Quantum dot (QD) LEDs useful for plant, algael and photosynthetic bacterial growth applications. The QD LEDs utilizes a solid state LED (typically emitting blue or UV light) as the primary light source and one or more QD elements as a secondary light source that down-converts the primary light. The emission profile of the QD LED can be tuned to correspond to the absorbance spectrum of one or more photosynthetic pigments of the organism.

  • Patent number: 9699856
    Abstract: A lighting fixture includes an outer frame, a solid-state light source, a lens, and a sensor module connector. Driver circuitry is coupled to the outer frame and provides one or more drive signals for powering the light source. The lens is supported by and attached to the outer frame. The solid-state light source is mounted to the outer frame and at least partially surrounded by the lens, such that at least a portion of the light provided by the solid-state light source is transmitted through the lens towards an area of interest. The sensor module connector is mounted to the outer frame and configured to accept a connector from a sensor module such that when the sensor module is installed in the lighting fixture, a surface of the sensor module faces the area of interest towards which light from the solid-state light source is provided.

  • Publication number: 20170173558
    Abstract: A method, device, article of manufacture and apparatus are disclosed for binding successive layers of a “guest specie” such as an atom, cation, anion, organic molecule, and/or pathogen to a substrate or multiple different substrates. Possible substrates include materials with a porous nature; macro, micro and nano porous materials are all candidates. The adsorbent capacity of a substrate is extended by coordinating a layer of bi- or multi-functional ligand (L) to an adsorbed atom or ion or molecule or pathogen, which is then coordinate to a second layer of adsorbed atom or ion or molecule or pathogen.

  • Patent number: 9670818
    Abstract: A reductant dosing system is disclosed as having a pump, and suction, discharge, and return passages. The system may also have a return valve, an air passage, and an air valve. The system may additionally have an air passage pressure sensor, a discharge passage pressure sensor, and a controller. The controller may be configured to calculate a first average pressure inside the discharge passage while the pump is off, the air valve is open, and the return valve is closed; and calculate a second average pressure inside the discharge passage while the pump is off, the air valve is open, and the return valve is open. The controller may also be configured to determine a pressure drop inside the discharge passage based on the first and second average pressures, and to determine that priming is successful based on the pressure drop and pressures of the discharge and air passages.
