  • Publication number: 20230019624
    Abstract: An information handling system includes a memory to store data associated with metrics of an individual and gaming performance metrics, and a processor. The processor correlates the metrics of an individual with the gaming performance metrics. Based on the correlation, the processor creates a gaming performance score. The processor determines changes to implement based on the gaming performance score. When the changes are implemented, the changes improve the gaming performance score. The processor provides the changes to the individual in a non-intrusive manner.

  • Patent number: 11468867
    Abstract: A system and method for providing acoustic output is disclosed, the system comprising a communication device, a processor coupled to the communication device, and a memory coupled to the processor. The processor receives multimedia data associated with a multimedia output stream, extracts audio data based on the multimedia data, and generates a rhythmic data set including time-series acoustic characteristic data based on the extracted audio data. A sequence of visual elements is generated based on the time-series acoustic characteristic data and associated with the respective visual elements in the sequence of visual elements with the multimedia data. The multimedia data for visually displaying the acoustic characteristic data concurrently with the multimedia stream is transmitted to a multimedia output device.

  • Patent number: 11368155
    Abstract: Embodiments of the disclosure provide an input output (IO) structure in which complimentary nodes of a level shifter are utilized to logically block the output of the IO structure from switching until both power supplies to the IO structure are powered up. An illustrative level shifter includes: a cross-coupled pair of PFETs configured to output complimentary voltage values at a first node and a second node; a control circuit configured to select which of the complementary voltage values are output to the first node and second node; a logic inverter having an input coupled to the first node and an output coupled to a third node; and a NAND gate having inputs coupled to the second node and third node and that generates a level shifted output.

  • Publication number: 20210355099
    Abstract: A highly efficient, Z-selective ring-closing metathesis system for the formation of macrocycles using a stereoretentive, ruthenium-based catalyst supported by a dithiolate ligand is reported. This catalyst is demonstrated to be remarkably active as observed in initiation experiments showing complete catalyst initiation at ?20° C. within 10 min. Using easily accessible diene starting materials bearing a Z-olefin moiety, macrocyclization reactions generated products with significantly higher Z-selectivity in appreciably shorter reaction times, in higher yield, and with much lower catalyst loadings than in previously reported systems. Macrocyclic lactones ranging in size from twelve-membered to seventeen-membered rings are synthesized in moderate to high yields (68-79% yield) with excellent Z-selectivity (95%-99% Z).

  • Patent number: 10884914
    Abstract: A technique for garbage collection in a storage system includes generating regrouping metadata for one or more pages of at least two logical erase blocks (LEB). The regrouping metadata indicates an associated stream for each of the pages.
