  • Publication number: 20230341761
    Abstract: An anti-reflective article includes a substrate including a surface and a bulk, and an arrangement of anti-reflective nanostructures along the surface of the substrate, each anti-reflective nanostructure of the arrangement of anti-reflective nanostructures being supported by the bulk of the substrate, each anti-reflective nanostructure of the arrangement of anti-reflective nanostructure tapering from the bulk of the substrate to define a respective peak. At least some of the anti-reflective nanostructures of the arrangement of anti-reflective nanostructures are linked with an adjacent anti-reflective nanostructure of the arrangement of anti-reflective nanostructures via a respective interconnection. The respective interconnections are in addition to the bulk of the substrate supporting the anti-reflective nanostructures. The respective interconnections are disposed at or above a midpoint between the peaks of the anti-reflective nanostructures and the bulk of the substrate.

  • Patent number: 11720706
    Abstract: A system, method, and computer-readable media for providing inline data loss prevention (DLP) within a group-based communication system. A DLP engine is included to apply an organization-specific DLP policy to a user input to determine whether the user input should be displayed in a group-based communication channel of the group-based communication system. Multiple organizations sharing a channel may each have their own respective organization-specific DLP policies applied to incoming and outgoing messages for that organization.

  • Publication number: 20160109883
    Abstract: There is provided a method and apparatus for offboard navigation of a 5 robotic device. The method comprising defining a threshold value of a positional accuracy of the robotic device, calculating latency of a network through which the robotic device and a server communicate, the latency of the network being a difference between sending sensor data from the robotic device to the server and receiving processed data corresponding to the 10 sent sensor data by the robotic device from the server, and determining speed of the robotic device based on the threshold value of the positional accuracy of the robotic device and the latency of the network.

  • Patent number: 9298837
    Abstract: Techniques are provided for a metasearch infrastructure. The metasearch infrastructure supports one or more of the following: hotel matching, backend support of user queries, frontend support for user queries, a cache layer that groups or organizes cached data in storage based on hotel location, scoring and ranking on the client side, experiments and rankers, duplicate booking prevention, blacklisting hotels, and indexing that utilizes a document-independent data structure to store index values.

  • Publication number: 20050289153
    Abstract: A method, system, and computer accessible medium for maintaining and sharing identity information for identities. Multiple types of identity information, including communication-related information, for multiple identities may be aggregated, stored in, and accessed through, a corresponding shared identity objects. Aggregated identity information for an identity may be stored in a corresponding shared identity object. Aggregated identity information may be accessed by applications through shared identity objects. Communication-related information may include indications of communication mechanisms. Communication with an identity may be initiated through a corresponding shared identity object using the communication mechanisms. The communication related information may also include an indication of the reach-ability of the identity through each of the communication mechanisms and may be requested and received form remote system associated with the identity.
