  • Patent number: 11088948
    Abstract: Systems and methods are provided to add flow identification information to packets of network traffic. Each packet can have flow identification information added based on the packet being sent to a full-proxy mode appliance. A stateful network routing service may intercept packets and determine the packets are to be sent to a full-proxy mode appliance. Based on this determination, the stateful network routing service may obtain or generate flow identification information to identify the packet. The stateful network routing service may add the information to the packet and transmit the enriched packet to a full-proxy mode network appliance. The stateful network routing service may receive a second enriched packet from the network appliance. The stateful network routing service can parse the second enriched packet for flow identification information and identify the second enriched packet based on the flow identification information.

  • Patent number: 11029170
    Abstract: An online system provides navigation information customized using travel preferences of users. The online system receives actions performed by users that may indicate their geographical locations of interest. The online system may use a model to predict a user's level of interest in destination geographical locations. The online system generates navigation information or travel information that describes routes from origin geographical locations of users to destination geographical locations to which the users are likely to travel. The online system transmits the navigation information to client devices for presentation as personalized or dynamically-created content items to users. The online system may generate navigation information using catalogs describing routes between geographical locations. For instance, the catalog indicates a vehicle for navigation along a route, as well as origin and destination geographical locations.

  • Patent number: 9976203
    Abstract: A cold rolled, annealed TRIP steel sheet which has a composition including (in wt. %): C: 0.1-0.3; Mn: 4-10, Al: 0.05-5, Si: 0.05-5; and Nb: 0.008-0.1, the remainder being iron and inevitable residuals. The cold rolled sheet has an ultimate tensile strength of at least 1000 MPa, and a total elongation of at least 15%. The cold rolled sheet may have at least 20% retained austenite in its microstructure and may have greater than 50% lath-type annealed ferrite structure. The cold rolled sheet may have an ultra fine grain size of less than 5 micron for the retained austenite and ferrite.
