  • Patent number: 12032079
    Abstract: An optical detector system provides positioning data to facilitate tracking in optical communications. The system provides first and second path lengths to direct light onto an array of photodetectors. Incoming first light with a first polarization is reflected by a polarizing beam splitter (PBS) to the array, resulting in a first path length and a relatively wide field of view (FOV). Incoming second light with a second polarization passes through the PBS, interacts with a first quarter wave retarder (QWR) and a convex mirror, is reflected by the PBS, passes through a second QWR and is reflected by a flat mirror to pass through the PBS again and onto the array. The second light experiences a second path length greater than the first path length, exhibiting a relatively narrow FOV. The resulting spots of light on the array provide information about a position of the incoming beam.

  • Patent number: 12033631
    Abstract: A system configured to perform self-trigger prevention to avoid a device waking itself up when a wakeword is output by the device's own output audio. For example, during active playback the device may perform double-talk detection and suppress wakewords or other device-directed utterances when near-end speech is not present. To detect whether near-end speech is present, an Audio Front End (AFE) of the device may perform echo cancellation and generate correlation data indicating an amount of correlation between an output of the echo canceller and an estimated reference signal. When the correlation is high in certain frequency ranges, near-end speech is not present and the device may suppress the utterance. When the correlation is low, indicating that near-end speech could be present, the device does not suppress the utterance and sends the utterance to a remote system for speech processing.

  • Patent number: 12033618
    Abstract: Techniques for determining and storing relevant context information for a user input, such as a spoken input, are described. In some embodiments, context information is determined to be relevant on an audio frame basis. Context scores for different types of context data (e.g., prior dialog turn data, user profile data, device information, etc.) are determined for individual audio frames corresponding to a spoken input. Based on the corresponding context scores, the most relevant context is stored in a local context cache. The local context cache is updated as subsequent audio frames, of the user input, are processed. The data stored in the context cache is provided to downstream components to perform tasks such as ASR, NLU and SLU.

  • Patent number: 12026718
    Abstract: Anomalies can be detected and related mitigation actions can be executed. For example, a computing device receives, from a first source, first data associated with a first process of a payment service in support of transactions of a first plurality of users. The computing device generates first aggregated metrics based on the first data. The computing device determines, by using the first aggregated metrics as first input to a machine learning engine, an anomaly associated with the execution of the first process. The computing device determines, based on the anomaly and a history of anomalies associated with the execution of the first process, an indication of an outage associated with the first process. The computing device causes an execution of a mitigation action based on the indication of the outage. The execution of the mitigation action is in support of transactions of a second plurality of users.

  • Patent number: 12028362
    Abstract: Techniques for enabling the identification of anomalous events associated with an object storage service of a cloud provider network using a variational autoencoder model including a pre-trained embedding for selected features of events are described. A variational autoencoder, for example, encodes data into a latent space and reconstructs approximations of the data from an encoding in the latent space. In this context, for example, anomalous events of interest might represent unauthorized or abusive behavior associated with storage resources provided by an object storage service (or in association with other types of computing resources provided by other services of a cloud provider network). Legitimate (or benign) access patterns to an object storage service can be modeled by utilizing observed data plane events stored by an account activity monitoring service. Once trained, the model can be used to identify anomalous events.

  • Patent number: 12028549
    Abstract: Methods of video streaming are generally described. In some examples, a camera device periodically captures an image, communicates encoded frame data representing that image to a server, and decodes and stores the previously encoded frame data as a background picture. The server receives the encoded frame data, decodes it, and stores the decoded frame in a buffer for future use. Subsequently, upon initiation of a streaming session, the camera device captures another image and encodes a predicted key frame based on differences between the captured image and the background picture. The camera device sends the predicted key frame to the server, which receives it and reconstructs a facsimile of the captured image utilizing the previously decoded frame stored in the buffer. Methods of acknowledging successfully decoded frames for use in selecting background pictures is also described.

  • Patent number: 12028268
    Abstract: Techniques implemented by a cloud computing system for providing fallback capacity providers to ensure that infrastructure capacity required to run containerized services is available despite primary capacity providers experiencing a failure. Cloud providers offer container-management services that automate the management and scaling of containerized services of users. The container-management services are supported by capacity providers that manage the computing infrastructure on which the containerized services run (e.g., servers, VMs, etc.). However, there are times when a capacity provider is unable to provision capacity for containerized services, such as due to a large scale failure. Rather than leaving capacity requests unserved, the container-management service designates a fallback capacity provider that acts as a failover for provisioning requested infrastructure capacity.

  • Patent number: 12028461
    Abstract: A request to add tags (e.g., labels, key-value pairs, or metadata) to resources can be digitally signed by the entity making the request, such that the source can be verified and an authorization determination made for each tag. For a request involving multiple services (or entities) that can each add tags, any tag added by a service can be included in the request and digitally signed by that service. Each service processing the request can also digitally sign the request before forwarding, so that each service signs a version of the request, which includes elements signed by other services earlier in the request chain. When the request is received to a tagging service, the service ensures that every tag was digitally signed by the appropriate authorized entity or service, and validates the signatures to ensure that no data was modified or omitted, before adding the tags to the designated resource(s).
