  • Patent number: 11902857
    Abstract: Systems and methods are provided for human activity analysis and localization using channel state information (CSI). A streamlined data processing and feature extraction approach that addresses concept drifts for time series data is provided. Data obtained from CSI or any other mechanism is used to estimate the wireless channel between two different wireless nodes (e.g., an access point (AP) and an associated station (STA)), and can be used to train a robust system capable of performing room level localization. A phase and magnitude augmented feature space along with a standardization technique that is little affected by drifts is also used.

  • Publication number: 20210192571
    Abstract: A content publisher incorporates a script into a web page. The script consumes an event raised in response a user submitting a query. The script captures the query and related information and sends the captured query and information to a search provider, either directly or through the content publisher. The search provider uses the query and information to identify both the content publisher and branding information associated with the content publisher. An iframe is assembled by the search provider that contains current results from the content publisher as well as web results. The iframe is branded with the content publisher branding information and returned to the user, either directly or through the content publisher. The resultant search experience appears as if it were provided by the content publisher.
