  • Publication number: 20220327537
    Abstract: A customer interfacing with a credential manager may be enabled to request and obtain securely from the credential manager additional details related to a service transaction previously effected between the customer and a service provider using a customer transaction credential managed by the credential manager. To obtain such a detailed customer receipt for presentation to a customer, the credential manager may provide an authenticatable customer receipt request to the service provider that may include certain information indicative of an active session between the credential manager and an authenticated customer and/or certain information indicative of a trusted relationship between the credential manager and service provider. When a request is authenticated, the service provider may provide a detailed customer receipt to the credential manager in a format that may be presented to the customer but that may not be used by the credential manager to easily access details conveyed by the receipt.

  • Publication number: 20190392441
    Abstract: Systems, methods, and computer-readable media are provided for customizing an authorization request schedule. In some embodiments, application of one or more statistical or rule-based models may be combined with the use of one or more learning-based models to provide a hybrid model approach to customizing an authorization request schedule that may allow for the personalization and flexibility of a learning model as well as the fine tunability of a statistical model.

  • Publication number: 20020003006
    Abstract: The present invention is directed to an alloy for a high-performance rare earth permanent magnet. This alloy has a metallographic structure of approximately two phases that comprises a Nd2Fe14B phase (1) consisting of hard magnetic crystal grains and an &agr;-Fe phase (2) consisting of soft magnetic crystal grains. The metallographic structure has an ultra-thin film (3) that contains a large amount of nonmagnetic metallic elements that have an atomic radius of between the atomic radius of Fe and the atomic radius of Nd at each of the crystal grain boundaries between the phases (1, 2) and that will not form solid solutions with either Fe or Nd. The nonmagnetic metallic elements consist of one or two or more elements selected from among Nb, Zr, Ta and Hf, the thickness of each ultra-thin film is 10 to 20 angstroms, and the sizes of the crystal grains in each of the phases (1, 2) are in the range 5 to 100 nm, preferably 10 to 40 nm.
