  • Publication number: 20240135296
    Abstract: In some examples, an environment evaluation system accesses interaction data recording interactions by users with an online platform hosted by a host system and computes, based on the interaction data, interface experience metrics. The interface experience metrics includes an individual experience metric for each user and a transition experience metric for each transition in the interactions by the users with the online platform. The environment evaluation system identifies a user with the individual experience metric below a pre-determined threshold, identifies a transition performed by the user that has a transition experience metric below a second threshold, and analyzes the transition to determine users who have performed the transition. The environment evaluation system updates the host system with the individual experience metrics and the transition metrics, based on which the host system can perform modifications of interface elements of the online platform to improve the experience.

  • Publication number: 20220285316
    Abstract: A memory device includes a substrate, a controller die, a flip chip die, first and second silicon dies, and bond wires. The controller and flip chip dies are attached to the substrate using connection balls and in electrical communication with each other. The first and second silicon dies include respective first and second contact pad surfaces. The bond wires electrically connect the contact pad surfaces to the substrate so the first and second silicon dies communicate with the controller die. The flip chip die and first and second silicon dies are NAND dies, the flip chip die is configured as SLC memory, and the silicon dies are configured as one of MLC memory, TLC memory, or QLC memory.

  • Patent number: 10199649
    Abstract: Set forth herein are positive electrode active material compositions, e.g., lithium-rich nickel manganese cobalt oxides. The lithium-rich nickel manganese cobalt oxides set forth herein are characterized, in some examples, by an expanded unit cell which maximizes the uniform distribution of transition metals in the crystalline oxide. Also set forth herein are positive electrode thin films including lithium-rich nickel manganese cobalt oxide materials. Disclosed herein are novel and inventive methods of making and using lithium-rich nickel manganese cobalt oxide materials for lithium rechargeable batteries. Also disclosed herein are novel electrochemical devices which incorporate these materials.
