  • Publication number: 20210216942
    Abstract: Aspects of the invention include a computer-implemented method including extracting, by a processor, a component of an identified competency from an underlying competency framework and creating, by the processor, a list of social networking elements associated with the extracted component of the identified competency. The method analyzes, by the processor, the created list of social networking elements of a social network of an individual using structural analysis and content analysis and combines, by the processor, the structural analysis and the content analysis in a model to determine a score for the individual for the component of the identified competency.

  • Patent number: 10985692
    Abstract: A system and method for heating a surface. The system can be a solar panel system and the surface can be a solar panel. The system includes a heat source and a processor. The processor determines an amount of heating energy for removing an accumulated material from the solar panel to obtain an unobstructed solar panel, determines an amount of energy production of the unobstructed solar panel, and controls the heat source to apply the determined amount of heating energy to the solar panel when the determined amount of energy production is greater than the amount of heating energy.

  • Publication number: 20190241459
    Abstract: A method of producing an optical fiber is provided that includes the steps of flowing a first gas into an optical fiber draw furnace. The first gas is passed through a heated section configured to contain and heat a glass source from which the optical fiber is drawn, passing the first gas through a muffle which defines a capture chamber. A portion of the first gas is removed through at least one reclaim port operatively coupled to the capture chamber. A second gas flows into a gas screen at a rate configured to substantially recover a pressure drop associated with removing the portion of the first gas.

  • Patent number: 10189479
    Abstract: Methods and apparatus are disclosed to monitor and evaluate vehicle operator behavior. An example method includes processing, using a particularly programmed processor, image data obtained with respect to a vehicle to identify an object in the image data. The example method includes measuring, using the mobile device, a geographic location of the vehicle. The example method includes determining, using the mobile device, an operating state of the vehicle. The example method includes analyzing the object in the image data, the geographic location, and the operating state of the vehicle to determine a behavior of the vehicle. The example method includes generating a score for a driver associated with the vehicle by comparing the behavior of the vehicle with a reference behavior, the reference behavior quantified by one or more driving metrics. The example method includes outputting the score.
