  • Publication number: 20230144503
    Abstract: Systems and methods for indexing and searching health data are disclosed herein. In some embodiments, a method for querying patient records includes receiving a search input that specifies a plurality of events, one or more temporal relationships between the events, and inclusion and/or exclusion criteria. An index query is constructed based at least in part on the plurality of events within the search input. The index query is then executed against an inverted index to identify matching patient records. One or more temporal constraints can be solved against the identified patient records. Finally, patient records satisfying the constraint(s) are returned.

  • Patent number: 10708374
    Abstract: Techniques for enabling notification from a network resource are described. In at least some embodiments, a user subscribes to receive notifications from a network resource, such as a website, a web-based resource, and so forth. The network resource can provide notifications to a client device of the user, such as a push notification indicating that content is available from the network resource. Based on the push notification, content from the network resource can be presented on the client device, such as in a notification indicator presented on the client device and associated with the network resource.

  • Patent number: 10075520
    Abstract: In one embodiment, a metric collection system may collect application metrics across multiple data centers in specific time intervals. A local collection point 108 may establish an absolute reference time for a local data center 102. The local collection point 108 may determine a source reporting interval for an application 106 based on the absolute reference time. The local collection point 108 may receive a source metric report 300 for the application 106 based on the source reporting interval.

  • Patent number: 9973589
    Abstract: Techniques for enabling a push notification from a website are described. In at least some embodiments, a push notification generally represents a way for a website to push information to a client device. For instance, a push notification may include content (e.g., text, images, video, audio, and so forth) that a website pushes to a client device. The content can be output via the client device, e.g., independently of an output of the website itself. According to one or more embodiments, a push notification channel is generated that enables notifications to be pushed from a website to a client device. Generally, a push notification channel represents a set of attributes and procedures that enable notifications to be securely and accurately pushed from a website to a client device.

  • Patent number: 9225538
    Abstract: Stateless application notifications are described that enable third parties to provide messages to client applications. A communication channel can be established between a notification service and an application. Upon request, the notification service can generate obfuscated routing data for the channel, which can be in the form of a channel handle or token. The routing data can be encrypted and digitally signed to obscure the content and format of the routing data from third parties. An application service possessing the obfuscated routing data can package a notification with the data and send the package to the notification service for delivery. The application service does so without knowing the channel particulars encoded by the obfuscated routing data. The notification service that produces the obfuscated routing data can decrypt and interpret the data, and deliver the notification on the channel to an appropriate endpoint application on behalf of the application service.

  • Patent number: 8782145
    Abstract: A content item hosted by a content item source (such as a weblog post of a weblog) may receive updates (e.g., comments submitted by users), and may be discussed among users in a chat group of a chat service. The content item source and the chat service may coordinate to notify users of updates to the content item, and to share content regarding the content item. When a user requests to subscribe to updates of the content item, the content item source may invite the user to join a chat group of the chat service created for discussion of the content item. Additionally, updates to the content item received by the content item source may be automatically posted as messages in the chat group, and messages posted in the chat group regarding the content item may be automatically posted as updates to the content item at the content item source.

  • Patent number: 8379525
    Abstract: Techniques to manage large numbers of subscribers to real-time events are described. Embodiments may filter subscribers dynamically into buckets where publications are distributed only to subscribers in the same bucket as the publisher. Buckets may be dynamically created and removed to lower or raise the publication rate for subscribers to an acceptable level. Embodiments may use a two-level bucketing algorithm for filtering that is memory and CPU efficient, and scales with large numbers of subscriptions. The techniques may also reduce the context loss for a subscriber when a new bucket has to be created and subscribers distributed between buckets. Embodiments may be scaled out to multiple servers, to accommodate very large numbers of subscribers and publications. Other embodiments are described and claimed.
