  • Patent number: 10839017
    Abstract: An autonomous robotic system using an adaptive, interactive, and cognitive reasoner utilizing an advanced memory graph structure receives a natural language input. The natural language input is processed to identify components. At least a portion of the components of the natural language input is stored in a short-term artificial intelligence memory graph data structure. A long-term artificial intelligence memory graph data structure includes data that was previously stored in the short-term artificial intelligence memory graph data structure but is no longer stored in the short-term artificial intelligence memory graph data structure.

  • Patent number: 8501958
    Abstract: A compound for absorbing sunlight and converting the sunlight into electrical energy, which is formed by coupling a fullerene with at least one or more triarylamine derivatives. The fullerene is selected from among those having carbon numbers C60, C70, C78, C82 and C84, and the triarylamine derivatives are coupled with at least one or more aliphatic or aromatic hydrocarbons and are also coupled with a dopant. A method of manufacturing the compound includes steps of synthesizing a fullerene derivative, synthesizing fullerene-triarylamine, wherein a fullerene-triarylamine adduct is prepared by coupling the fullerene derivative with a triarylamine derivative, preparing an adduct solution by dissolving the fullerene-triarylamine adduct in an organic solvent, and conducting a doping reaction by adding an acid dropwise slowly to the adduct solution.
