  • Patent number: 12170666
    Abstract: A system receives an authentication request from a requestor system for a token to access one or more computing resources associated with a computing resource service provider. The system analyzes information included with the authentication request and, based on the information included with the authentication request, selects an authentication provider from a plurality of authentication providers without additional input from the requestor system. The requestor system is redirected to the selected authentication provider such that the token is provided in response to the authentication request. The requestor system then presents the token to obtain an identity assertion that can be used to access the one or more computing resources.

  • Patent number: 11945585
    Abstract: An aircraft includes a main body having an empennage, a main rotor assembly mounted on the main body, and a movable control surface assembly supported on the empennage. The movable control surface assembly includes a tube extending from the empennage along a tube axis to a free end, the tube being supported for rotation about the tube axis with respect to the empennage, and a movable control surface mounted on the tube for rotation therewith. The movable control surface is supported on the tube by a connection element that couples the movable control surface to the free end of the tube to rotatably fix the movable control surface with respect to the tube.

  • Patent number: 10992670
    Abstract: This disclosure describes techniques for utilizing strong authentication of device identities and/or user identities to establish secure network tunnels between client devices and a virtual private network (VPN) server of a service provider network. The service provider network may generate routes from the VPN server to services to establish a connection for the client device to access the services. The service provider network may receive posture data from the client device that indicates a state of the client device, and determine, using a security policy, with which services the client device is permitted to interact or utilize. Further, the techniques described herein include receiving requests from the services to provide cryptographic assertion(s) that were used by the VPN server to authenticate the device identities and/or user identities. In this way, the services may be able to perform strong authentication of the client devices that are attempting to utilize the services.

  • Publication number: 20200044885
    Abstract: A node forms a network by scanning for an existing network. If an existing network is not found, the node operates as a network controller node of the first network and admits at least one client node to the first network. As a network controller node, the node designates one of the client nodes as a scout node. The scout node removes itself from the first network and scans for a second network. If the scout node does not return to the first network after a predetermined time, it is assumed that the scout node has found a second network. The network controller node of the first network then designates the remaining client nodes as scout nodes, and then joins the second network as a client node. Therefore, multiple networks are avoided.

  • Publication number: 20180251221
    Abstract: A system and method to release a subject device includes a passage associated with the subject device, the passage having a first end and a second end, at least one hinged door associated with the second end of the passage, and at least one urging member to urge the at least one hinged door closed and to selectively open the at least one hinged door in response to the subject device contacting the at least one hinged door.

  • Patent number: 8996680
    Abstract: A non-transitory computer readable media having instructions stored thereon that, when executed by a processor, cause the processor to optimize a network that is formed from a plurality of nodes. The instructions cause the processor to execute an order that the plurality of nodes perform a probing operation. The order is typically round robin. The processor receives a request from a client that identifies a next node to perform the probing operation. Based on the request, the processor changes the order so that the next node performs the probing operation after the current node that is performing the probing operation has completed the operation.

  • Patent number: 8849969
    Abstract: A method is disclosed for optimizing a network that is formed from a plurality of nodes. The NC node of the network compiles an order that the plurality of nodes perform a probing operation. The order is typically round robin. The NC node receives a request from a client that identifies a next node to perform the probing operation. Based on the request, the NC node changes the order so that the next node performs the probing operation after the current node that is performing the probing operation has completed the operation.
