  • Patent number: 12346903
    Abstract: Embodiments are directed to the generation of a token associated with a status. The status of the token may affect how the token is treated and the types of restrictions placed on the token. The status of the token may indicate that the token is generated based on verification of secure user data. Alternatively, the status of the token may indicate that the token is generated based on insufficient user data and, as such, restrictions may be imposed on the token. The token requestor may be a mobile application, such as a merchant mobile application provisioned on a user device. In response to a token request from the merchant, the token provider issues tokens with varying status based on a confidence level. The status of the token may be indicated in terms of token assurance level.

  • Publication number: 20250133425
    Abstract: A system receives the log messages including data regarding one or more cell site performance issues of a cell site. Based on the log messages, the system determines whether there is a time-based correlation between a cell site router (CSR) of the cell site experiencing a cold start and the one or more cellular site performance issues. Then, based on the determination whether there is a time-based correlation between the CSR experiencing a cold start and the one or more cell site performance issues, the system electronically generates an action item associated with addressing the one or more cell site performance issues.

  • Publication number: 20240417752
    Abstract: Disclosed are data pipelines for string extraction, clustering, and comparison. A method may include extracting, from each plasmid genome sequence sequenced from genomes of plasmids, based on the presence of fixed flanking sequence markers (FFSMs) in the plasmid genome sequence, sequence regions. Each sequence region is within the FFSMs and includes a candidate inverted terminal repeat (ITR) sequence. The example method further includes clustering, based on perfect sequence identity, two or more sequence regions of the sequence regions to generate a clusters, merging, based on an alignment between their corresponding sequence regions, two or more clusters of the clusters; when a single cluster remains, identifying, based on a local alignment, a genotype of a candidate ITR sequence of the single cluster, and manufacturing, based on the genotype of the candidate ITR sequence, a plurality of AAV vectors using plasmids having ITR sequences with the genotype of the candidate ITR sequence.

  • Publication number: 20240274538
    Abstract: Methods for forming microelectronic devices include forming a staircase structure in a stack structure having a vertically alternating sequence of insulative and conductive materials arranged in tiers. Steps are at lateral ends of the tiers. Contact openings of different aspect ratios are formed in fill material adjacent the staircase structure, with some openings terminating in the fill material and others exposing portions of the conductive material of upper tiers of the stack structure. Additional conductive material is selectively formed on the exposed portions of the conductive material. The contact openings initially terminating in the fill material are extended to expose portions of the conductive material of lower elevations. Contacts are formed, with some extending to the additional conductive material and others extending to conductive material of the tiers of the lower elevations. Microelectronic devices and systems incorporating such staircase structures and contacts are also disclosed.

  • Publication number: 20230201945
    Abstract: Compositions and methods for coupling metals to aluminum surfaces are provided. The compositions are prepared as aqueous solutions or suspensions, and can be applied to the aluminum surface using conventional printing techniques. Rheology of the printable composition can be adjusted to provide a gel or a cream. Curing steps, if necessary, are performed at low temperatures that are compatible with plastic/polymer components of mass produced devices, such as aluminum RFID antennae.

  • Publication number: 20200232098
    Abstract: Methods of patterning electroless metals on a substrate are presented. The substrate is covered by a blocking reagent. After formation of a catalyst blocking layer on the substrate, portions of the catalyst blocking layer are removed to form a circuit pattern. A catalyst is placed the surfaces of both the catalyst blocking layer and the exposed substrate. The catalyst blocking layer prevents or reduces catalytic activity of the catalyst. Electroless metal plating is performed to plate a metal at the active portions of the catalyst.

  • Publication number: 20200190670
    Abstract: Devices, systems, and methods are contemplated for depositing metals to the surface of a substrate. A first precursor ink including a metal is applied to a surface of the substrate, and the precursor ink is reduced to deposit the metal to the substrate, preferably by thermal reduction, forming a first metal layer. A second precursor ink having a second metal is then applied to the substrate, at least partially over the first metal layer. The second precursor ink is then reduced, typically by chemical reduction, depositing the second metal over the first metal layer in a globular fashion. Precursor inks are also disclosed having an alkyl metal carboxylate, a cyclic amine, and at least one of an ester, a hydrocarbon, or an ether.
