  • Patent number: 10893091
    Abstract: Features are provided for the asynchronous transmission of media files that are part of, or otherwise associated with, user-created content posts. The media file transmissions are asynchronous in nature because the media files are transmitted in parallel background processes while users continue creating content posts or performing other computing tasks. The client devices on which the media file transmissions are initiated can manage the establishment of connections to a network-accessible content management system, and also manage the continued transmission of the media files to the content management system while the users perform other tasks using the client devices.

  • Publication number: 20210006442
    Abstract: Devices, systems and methods generate a packet including a first preamble and a narrow band packet. Embodiments assign a first frequency band to the first preamble and assign a second frequency band to the narrow band packet. The second frequency band is a first sub-band of the first frequency band. Embodiments transmit the packet by transmitting the first preamble across the first frequency band and transmitting the narrow band packet across the second frequency band. The narrow band packet includes a second preamble and narrow band packet data.

  • Publication number: 20200396625
    Abstract: Disclosed are methods and systems for delaying packet transmissions over a wireless communication channel until a more favorable channel condition is detected. A device may measure a channel metric when it receives periodic beacon signals. The device may compare the channel metric against a programmed metric threshold. If the channel metric is less than the metric threshold, the device may delay the transmission of a packet until a later transmission window or transmit opportunity (TXOP) when the channel metric rises above the metric threshold, indicating the presence of a more favorable condition for transmission, or until a preconfigured timeout period elapses before the more favorable condition is found.

  • Patent number: 10846110
    Abstract: Disclosed herein are system, method, and computer program product embodiments for measuring graphical user interface (GUI) usage, generating visual depictions of the GUI usage, and providing GUI modification recommendations based on the GUI usage. A user interface (UI) usage measurement system may monitor user interactions with an application from one or more user devices. The UI usage measurement system may data such as button clicks or other icon interactions on a GUI. After aggregating this information, the UI usage measurement system may apply machine learning techniques to determine a GUI object recommendation. The recommendation may include the movement of one or more GUI objects to different locations so that the user may more quickly access GUI objects that are more heavily utilized. In this manner, the UI usage measurement system may modify the GUI used by a particular user to access elements of an application.

  • Patent number: 10783151
    Abstract: Features are provided for proactively grouping content for personalized content feeds based on the expected relevance of the content to groups or classes of users. Such proactive grouping can allow personalized (or semi-personalized) content feeds to be delivered with low user-perceived latency. The proactive grouping may be used in conjunction with a more computationally-intensive and higher-latency process for generating personalized feeds. A user's content feed may be provided using a two-phase delivery process in which an initial set of content for the feed is provided from the proactively grouped content collection with which the user is associated. While the user is viewing the initial set of content, the second phase of the delivery process may be performed in which additional content is selected specifically for the user.

  • Patent number: 10728291
    Abstract: Features are provided for the use of persistent connections and efficient content synchronization in content delivery environments. A content management system may provide content feeds to user devices using a persistent duplex connection over which the content management system and user devices may communicate asynchronously. By using a persistent duplex connection to asynchronously communicate with user devices, the content management system can provide content for the content feeds while, in parallel, receiving requests and commands from the user devices, responding to the requests and commands, and transmitting other requests and commands to the user devices. In addition, the content management system and a particular user device can exchange information regarding the content items that the user device has or should have already received.
