  • Publication number: 20220295233
    Abstract: A location-aware electronic device is provided. The electronic device trains feature extraction layers, reconstruction layers, and classification layers. The training may be based on a reconstruction loss and/or a clustering loss. The electronic device processes a fingerprint to obtain an augmented fingerprint using randomization based on statistics of the fingerprint. The feature extraction layers provide feature data to both the reconstruction layers and the classification layers. The classification layers operate on the codes to obtain an estimated location label. An application processor operates on the estimated location label to provide a location-aware application result to a person.

  • Publication number: 20220277209
    Abstract: A system and a method are disclosed for a tool that generates a provider score corresponding to a predicted performance of a provider based on data of claims involving the provider. For a given claim, the tool provides the data as input into a supervised machine learning model and receives as output from the supervised machine learning model a predicted performance of the claim. The tool also inputs the data of the claim into an unsupervised machine learning model that is selected based on a stage of claim processing that the claim belongs to and receives as output from the unsupervised machine learning model an identification of a cluster of candidate claims to which the claim belongs. The tool combines the outputs of the supervised machine learning model and the unsupervised machine learning model to generate the provider score.

  • Publication number: 20220270871
    Abstract: Methods for pre-cleaning substrates having metal and dielectric surfaces are described. The substrate is exposed to a strong reductant to remove contaminants from the metal surface and damage the dielectric surface. The substrate is then exposed to an oxidation process to repair the damage to the dielectric surface and oxidize the metal surface. The substrate is then exposed to a weak reductant to reduce the metal oxide to a pure metal surface without substantially affecting the dielectric surface. Processing tools and computer readable media for practicing the method are also described.

  • Publication number: 20220263130
    Abstract: An improved gel composite electrolyte membrane and a method of its manufacture are provided. The method includes mixing polymer precursors, a lithium salt, and a ceramic filler in a vessel to form a mixture. The mixture is cast on a preheated substrate and cured to form a crosslinked composite electrolyte membrane. The composite electrolyte membrane is plasticized by immersing the composite electrolyte in a plasticizer to obtain a gel composite electrolyte membrane. The addition of a plasticizer and a ceramic filler synergistically and simultaneously act to improve the Li+ transference number and Li+ conductivity of the resulting composite electrolyte, exhibiting high ionic conductivity and mechanical stability as well improved cycling performance. The gel composite electrolyte membrane is particularly suitable for, but not limited to, lithium metal batteries.
