  • Patent number: 12056072
    Abstract: Techniques to reduce the latency of data transfer notifications in a computing system are disclosed. The techniques can include receiving, at a memory, a first access request of a set of access requests associated with a data transfer. The first access request has a token and an access count indicating the number of access requests in the set of access requests. A counter is initiated to count the number of received access requests having the token. When additional access requests belonging to the set of access requests are received, the counter is incremented for each of the additional access requests being received. A notification is transmitted to an integrated circuit component in response to receiving the last access request of the set of access requests having the token to notify the integrated circuit component that the memory is ready for access.

  • Patent number: 12058176
    Abstract: A connection-based service impersonates request-based security for requests from clients that do not include credentials for the requests (e.g., data plane requests made via a connection-oriented security). A connection between a client and a connection-based service is established based on connection credentials that are based on security credentials from a request-based security service. The credentials are sent by a security component of the service to a local agent of the remote security service to be authenticated by the security service. An impersonation token is returned by the security service and cached by the local agent. Requests from the client to perform operations do not include credentials. For each request, the service passes an identifier for the client and the operation to a local authorization component that calls the agent for authorization of the requested operation. The agent uses the impersonation token to obtain authorization for the requested operation.

  • Patent number: 12056640
    Abstract: This disclosure describes a system for determining an estimated user departure time from a materials handling facility. For example, a user may enter a materials handling facility to pick one or more items from the materials handling facility. Those items may be provided to an agent for processing, such as packing, while the user picks other items within the materials handling facility. To ensure that the items are processed in a timely manner and made available to the user when the user is ready to depart from the materials handling facility, the implementations discussed determine an anticipated user departure time and compare that time with an estimated processing time needed to process the items.

  • Patent number: 12056158
    Abstract: Systems and methods are provided to implement a fast recovery process in a partitioned replicated data store. In some embodiments, the data store is configured to store an object in a plurality of partitions and replicate data in each partition in a group of replica nodes to satisfy a durability model. In response to a replica failure, the data store performs a split operation to create a plurality of new partitions. The partition's data is split into subsets corresponding to the new partitions. The subsets are transmitted, in parallel, from the surviving replica nodes of the partition to new replica nodes in the new partitions. The new partitions then replicate respective subsets of data in their respective replication groups using a chained replication technique. The recovery process allows the data store to return into compliance with the durability model more quickly, by parallelizing the copying of data.

  • Patent number: 12058509
    Abstract: A system configured to create a flexible home theater group using a variety of different devices. To enable the home theater group to generate synchronized audio, the system performs device localization to generate map data, which represents locations of devices in a device map. The map data may include a listening position and/or television, such that the map data is centered on the listening position with the television along a vertical axis. To generate the map data, the system selects a primary device that determines calibration data indicating a sequence when each of the individual devices generates playback audio. The primary device sends the calibration data to secondary devices and each device generates playback audio at a designated time in the sequence, enabling other devices to capture the output audio and determine a relative position of the playback device (for example using angle of arrival and distance information).
