  • Publication number: 20240137355
    Abstract: A system and method for providing secure access to an organization's internal resources by an application running on an external network. An agent accepts queries from the application which are passed to a relay with a dynamic filter. The relay establishes a secure connection with a connector through the organization's firewall and passes requests from the application to an authentication service running on the internal network to confirm that a user of the application is authorized and issue an authentication ticket which is returned to the application. The application then sends a request to access a specific internal resource based on the authentication ticket, which is passed to a ticket granting service running on the internal network, to verify that said user is authorized to access the specific internal resource, and, if so, issue a service ticket to grant access the application for that resource.

  • Publication number: 20240023985
    Abstract: Described herein are methods using mechanical inverting tube apparatuses to remove clot (e.g., thrombectomy), the apparatuses including an inversion support catheter having an expandable funnel-shaped distal end, and a flexible tube that can be continuously rolled over the funnel-shaped distal end and invert into the inner lumen of the inversion support catheter.

  • Publication number: 20220387053
    Abstract: Inverting tube apparatuses having an inverting tube (e.g., a knitted tube) that is configured to roll into an inversion support catheter and capture material from within a body lumen such as a blood vessel, in which the knitted tube is configured to prevent locking down onto the outside of the inversion support catheter. The inversion support catheter may include an expandable funnel at the distal end thereof having an interior profile that is adapted to capture and break apart hard material captured by the tractor so that it may be pulled into the inversion support catheter for removal.

  • Publication number: 20070033652
    Abstract: The present automatic update mechanism provides a method for periodically checking for updates to support a trusted environment. During the periodic check, an indication from an update service is received if there is a recommended update. Upon receiving the indication, a new revocation list is downloaded from the update service and saved as a pending revocation list. The pending revocation list is then available for on-demand update when protected content requests a higher level of protection on a computing device than the protection provided by a current level of protection on the computing device.

  • Publication number: 20070033420
    Abstract: The present automatic update mechanism provides a method for determining whether computer-readable components loaded within a memory device are at a level of protection specified for protected content that a media application is attempting to process. If a current level of protection provides lower protection that the level specified, a file is updated to achieve at least the level of protection specified by the protected content. Updating the file to achieve the level of protection is performed in a manner that minimizes rebooting of a computing device.

  • Publication number: 20060242080
    Abstract: To communicate requirements for a digital license from a receiver of corresponding digital content to a computing device upon which the digital content is to be rendered, the receiver tunes the content and locates within the content information relating to the requirements for the license, constructs the requirements from the located information, and sends such constructed requirements to the computing device. The computing device upon receiving the sent requirements constructs the license based on such received requirements, stores such constructed license in a license store of such computing device, and thereafter renders the content only in accordance with the license. Thus, the receiver need not communicate the license itself to the computing device.

  • Publication number: 20060184646
    Abstract: An enterprise network architecture has a trust link established between two autonomous network systems that enables transitive resource access between network domains of the two network systems. The trust link is defined by data structures maintained by each of the respective network systems. The first network system maintains namespaces that correspond to the second network system and a domain controller in the first network system, or a first network system administrator, indicates whether to trust individual namespaces. An account managed by a domain in the second network system can request authentication via a domain controller in the first network system. The first network system determines from the trust link to communicate the authentication request to the second network system. The first network system also determines from the trust link where to communicate authorization requests when administrators manage group memberships and access control lists.

  • Publication number: 20050235361
