  • Patent number: 11251974
    Abstract: A method of provisioning a first digital certificate and a second digital certificate based on an existing digital certificate includes receiving information related to the existing digital certificate. The existing digital certificate includes a first name listed in a Subject field and a second name listed in a SubjectAltName extension. The method also includes receiving an indication from a user to split the existing digital certificate and extracting the first name from the Subject field and the second name from the SubjectAltName extension of the existing digital certificate. The method further includes extracting the public key from the existing digital certificate, provisioning the first digital certificate with the first name listed in a Subject field of the first digital certificate and the public key, and provisioning the second digital certificate with the second name listed in a Subject field of the second digital certificate and the public key.

  • Patent number: 10183287
    Abstract: A method of coating a substrate includes distributing a first catalyst slurry having a first catalytic composition and a first initial viscosity within the substrate to form a first catalyst layer within the substrate; adjusting the viscosity of the first catalyst layer such that the first catalyst layer is made to have a first adjusted viscosity that is greater than the first initial viscosity of the first catalyst slurry; distributing a second catalyst slurry having a second catalytic composition and a second initial viscosity within the substrate to form a second catalyst layer within the substrate, the second initial viscosity being made to be less than the first adjusted viscosity; the second catalyst slurry being distributed within the substrate while the first catalyst layer is in a wet state such that the second catalyst layer is formed as a wet-on-wet coating that at least partially overlaps the first catalyst layer.

  • Patent number: 9055059
    Abstract: A method of combining digital certificates at a prescheduled time is provided. The method includes receiving, by a processor, data from a first certificate and data from a second certificate and determining a certificate combination date. The certificate combination date directs a combining of the first certificate and the second certificate to form a combined certificate. The method further includes detecting the occurrence of the certificate combination date and combining the first certificate and the second certificate to form the combined certificate in response to detecting the occurrence of the certificate combination date.

  • Publication number: 20090291748
    Abstract: A game piece management system comprising a piece sales system for allowing players to purchase pieces operable for playing at least one game, an account management system for maintaining player accounts, each player account identifying pieces owned by a player, and, a game interface for providing the player with access to a game session of an online game, the game interface allowing the player to select at least one piece from the player's account for use as an active piece in the game session. The player's active piece interacts with another player's active piece in the game session under control of the player, such that if the player's active piece neutralizes the other player's active piece, the other player's neutralized active piece becomes available to be obtained by the player.

  • Patent number: 6906619
    Abstract: A vehicle (30), such as an automobile, has an indicia controller (31) that can determine, via one or more direction-of-visual-attention sensors (32) a likely direction of visual attention for a given occupant of the vehicle such as, for example, the driver or another passenger. When a predetermined condition is sensed by one or more condition sensors (34, 35) (such as, for example, a predetermined hazard or other unsafe operating condition), the indicia controller can determine whether the monitored person is likely looking in a direction that likely includes the condition of concern. A particular condition indicia (36) as corresponds to the detected condition can then be provided as a function, at least in part, of whether the driver or other monitored person is already likely looking at, and is hence aware of, the detecting condition.
