  • Publication number: 20200396695
    Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer-readable media, for controlling transmission power in a network having multiple access points (APs). In one aspect, by enabling control of transmission power adjustment operations, APs can effectively delivery data to stations (STAs) within the basis service set (BSS) in a manner that minimizes co-channel interference between nearby APs in the network. The transmission power adjustment operations may be used to generate an interference reduction plan that accounts for some or all of the traffic patterns in the network, the capacities of the APs in the network and the service needs of all the STAs in the network. In this manner, APs are afforded a more lenient approach to adequately delivering data to STAs within the BSS, while mitigating interference with other APs or STAs operating in nearby wireless coverage areas.

  • Patent number: 10839028
    Abstract: A system for querying web pages to validate entity names is disclosed. The disclosed system receives a request for validating an entity name. The system identifies a search web link based on the information in the request. The system converts the request to a format appropriate for a search web page corresponding to the search web link. Then, the system sends the formatted request to the search web page via the search web link. The system receives a result web page and extracts a set of result entity names. The system then computes a hash value for the entity name in the request and each of the result entity names. Next, the system compares the hash value computed for the entity name in the request with hash values computed for each of the result entity names and determines a matching score for each of the result entity names based on the comparison of the hash values.

  • Patent number: 10599361
    Abstract: A backup agent for orchestrating backups of production hosts includes a persistent storage that stores backup policies and a backup manager that obtains a backup analysis request for a virtual machine hosted by the production hosts; generate a dependency graph based on: backups associated with the virtual machines, and the backup policies associated with the backups; and displays a graphical user interface, using the dependency graph, including user interactive markers based on the backups and dependency indicators interconnecting the user interactive markers. While the graphical user interface is displayed, the backup manager obtains a potential backup policy update based on a user interaction with one of the user interactive markers. After obtaining the potential backup policy update, the backup manager updates the graphical user interface to reflect the potential backup policy update. After updating the graphical user interface, the backup manager initiates generation of the backup.

  • Publication number: 20190300718
    Abstract: Provided herein are articles including repellent coatings, as well as methods of making as using these articles. The articles can comprise a substrate and a repellent coating disposed on a surface of the substrate. The repellant coating can comprise hydrophobic particles dispersed within a polymer binder. The hydrophobic particles can be aggregated within the polymer binder, thereby forming a multiplicity of re-entrant structures embedded within and protruding from the polymer binder. The repellent coatings, and by extension the articles described herein, can exhibit selective wetting properties (e.g., superhydrophilicty/super-oleophobicity, or super-hydrophobicity/superoleophilicity).

  • Publication number: 20190281608
    Abstract: This disclosure provides systems, methods and apparatuses for channel selection and channel selection planning in a network including a root AP (RAP) and a number of satellite APs (SAPs). The root AP may assign operating channels for one or more of the satellite APs in a manner that optimizes network performance by considering the impact that each of the satellite APs (as well as their respective client devices) may have on the network. In some implementations, the root AP may provide centralized channel selection planning for the network based a number of network parameters observed by one or more of the satellite APs. The network parameters may include, for example, channel conditions, traffic loads, traffic patterns, service needs of client devices, available channels, and other network utilization information observed by one or more of the satellite APs.
