  • Patent number: 10273407
    Abstract: Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape).

  • Publication number: 20190072976
    Abstract: A cooperative vehicle-highway communication system allows vehicles and pedestrians to determine their location by sensing selected coatings on roadways, sidewalks, and other paved surfaces in both indoor and outdoor environments. The systems recognize intelligent materials under sensors to determine geo-location. The intelligent materials are incorporated into paints on the roadway surface to mark key locations. Additionally, vehicles recognize highway paint/markings and signs with intelligent paint that provide specialized message content to support driver information and control applications. The intelligent paint materials include a coating that absorbs light while converting the absorbed light to electromagnetic energy. This electromagnetic energy is read by sensors to recognize the materials.

  • Patent number: 7409833
    Abstract: An apparatus and method for compressing gas refrigerant using two different compressors operated alternatively in a series or parallel mode for obtaining two different compression ratios and thereby provide efficient operation for both a relatively lower suction pressure and a relatively higher suction pressure. This system avoids an unbalanced mass flow rate when the compressors are operated in series by unloading a downstream one of the compressors. When operated in the series mode, refrigerant is bypassed back to a suction inlet of the downstream compressor during a portion of a compression stroke of the downstream compressor for equalizing the mass flow rate through the two compressors.
