  • Patent number: 11922284
    Abstract: There is a need for solutions that generates a temporally dynamic prediction for a particular prediction input. This need can be addressed by, for example, processing the prediction input using each of a plurality of temporally trained machine learning models to generate a corresponding model-specific prediction inference of a plurality of model-specific prediction inferences and processing the plurality of model-specific prediction inferences using an ensemble model to generate the temporally dynamic prediction for the prediction input.

  • Patent number: 11121279
    Abstract: An electrically controllable and tunable electromagnetic-field absorber/thermal emitter is invented using graphene/two-dimensional materials based multilayer nanostructures that have the absorption efficiency of unity at mid-infrared wavelengths. Alternating layers of graphene and hexagonal boron nitride are deposited between support materials and grown on a substrate. Tungsten may be used as the substrate, and silicon carbide as the support material; or, silicon may be used as the substrate and tungsten disulfide as the support material depending on the operating frequencies and ambient temperature. The invention demonstrates a selectable, tunable and switchable electromagnetic-field absorption or thermal emission by changing a DC bias that alters the chemical potential of the graphene layers and thereby the optical response of the multilayer nanostructures.

  • Publication number: 20090217977
    Abstract: A photonic-crystal based frequency- and angle-selective absorber for solar TPV systems is provided. The solar radiation absorber includes at least one photonic crystal with absorptivity over a broad range of frequencies, improved absorptivity within a selected solid angle, and reduced absorptivity outside the selected solid angle.

  • Patent number: 6630290
    Abstract: A system of etching using quantum entangled particles to get shorter interference fringes. An interferometer is used to obtain an interference fringe. N entangled photons are input to the interferometer. This reduces the distance between interference fringes by n, where again n is the number of entangled photons.
