Abstract: A content retrieval system may receive a query associated with a plurality of content items in a repository. For each content item of the plurality of content items: a respective first and second similarity score may be generated based on a similarity between embeddings indicative of a first and second data type generated from the query and for the content item; and a respective normalized similarity score may be generated based on a combination of the respective first and second similarity scores. A set of content items with respective normalized similarity scores that satisfy a similarity score threshold may be identified. An exact-match (lexical) search may yield respective mapping scores for content items that may also be ranked. An output indicative of content items that are identified in the set of content items with high-ranking similarity scores and identified in the set of content items with high-ranking mapping scores.

The method may include randomized emission of data bits over a plurality of frequency ranges to allow temporal and frequency voting.

The audio signal may be then demodulated using a unique confidence score based on the power of all the frequencies emitted to find the data transmitted.

Abstract: A data storage interface layer provides access management and transformation of data stored in various backend storage clusters. The data storage interface can serve as a point of access for data accessors to access stored data via a consistent data access protocol, even when a data storage cluster on which requested data is stored may use a different protocol. The data storage interface can also provide in-line transformation of requested data and/or control of access to requested data.

Abstract: A method of traffic forwarding and disambiguation through the use of local proxies and addresses. The technique leverages DNS to on-ramp traffic to a local proxy. The local proxy runs on the end user's device. According to a first embodiment, DNS is used to remap what would normally be a wide range of IP addresses to localhost based on 127.0.0.0/8 listening sockets, where the system can then listen for connections and data. In a second embodiment, a localhost proxy based on a TUN/TAP interface (or other packet interception method) with a user-defined CIDR range to which the local DNS server drives traffic is used. Requests on that local proxy are annotated (by adding data to the upstream connection).
