  • Patent number: 12007963
    Abstract: Systems, computer program products, and methods are described herein for processing resources and associated metadata in the metaverse using knowledge graphs. The invention relates to a method for processing and converting documents from a digital data source, involving the following steps: receiving one or more documents from the data source; storing the documents in a network attached storage using a file transfer protocol; converting the documents into an extensible markup language (XML) format; storing the converted documents in an API-accessible document database; generating a downstream process API for accessing the document database; creating an abstract document delineation for the converted documents based on data extracted via the downstream process API; and finally, transforming the abstract document delineation and associated metadata into a semantic, immersive, actionable ontological modeling language, facilitating enhanced document representation and interaction.

  • Patent number: 10207699
    Abstract: A vehicle propulsion system includes a combustion engine configured to output a propulsion torque to satisfy a propulsion demand, and a traction electric machine to generate a supplemental torque to selectively supplement the propulsion torque. The propulsion system also includes a controller programmed to forecast an acceleration demand based on at least one estimation model. The controller is also programmed to issue a command indicative of a required axle torque corresponding to the acceleration demand. The controller is further programmed to engage at least one fuel conservation action in response to the required axle torque being within a first predetermined torque threshold range.

  • Patent number: 7925421
    Abstract: A fuel control system of an engine includes a simulation module and a control module. The simulation module generates a simulated pre-catalyst exhaust gas oxygen (EGO) sensor signal based on a simulated oxygen concentration of an exhaust gas. The simulation module determines a simulated pre-catalyst equivalence ratio (EQR) for the exhaust gas based on the simulated pre-catalyst EGO sensor signal. The control module generates a desired pre-catalyst EGO sensor signal based on a desired oxygen concentration of the exhaust gas. The control module determines a desired pre-catalyst EQR based on the desired pre-catalyst EGO sensor signal. The control module determines a cost function based on the simulated pre-catalyst EQR and the desired pre-catalyst EQR. The fuel control system is calibrated based on the cost function.
