Abstract: A translation buffer is provided in parallel to a translation lookaside buffer (TLB) to cache translations between intermediate physical addresses (IPAs) and pointers for entries in the TLB corresponding to the IPAs. The pointers can be used to identify and invalidate only certain entries in the TLB as compared to invalidating the whole TLB.

Abstract: A method includes receiving video data from an A/V recording and communication device (A/V device) having a camera, the video data representing an object in a field of view (FOV) of the camera. The method further includes receiving, from the A/V device, identifying information for a wireless device proximate the object in the FOV of the camera (the FOV identifying information). The method further includes, after receiving the FOV identifying information, storing the video data and the FOV identifying information in a memory. The method further includes receiving identifying information for one or more wireless devices associated with activity of interest (the identifying information of interest). The method further includes determining that the FOV identifying information matches the identifying information of interest.

Abstract: A device in a home security system may detect a disconnect from a network and enter automatic setup mode based on trigger conditions. The trigger conditions are used to determine that the disconnect is based on changes to network configuration settings. The trigger conditions may include failing multiple attempts to access the network using a saved network password, or determining that an access point signal with a saved service set identifier has not been detected for at least a threshold time. Based on one or more trigger conditions being met, the device may enter automatic setup mode to receive updated configuration settings from a client device.

Abstract: A computer-implemented failure monitoring system and method are used with at least one server and with a plurality of resource servers. The system includes a computer storage device that stores one or more failure parameters indicative of one or more failure conditions. The system further includes one or more computer processors that include a monitoring component, an analysis component, and a throttling component. The monitoring component obtains information regarding service requests transmitted by the at least one server for which corresponding responses have not been timely received. The analysis component compares the information to the one or more failure parameters and determines whether at least one failure condition exists. The throttling component selectively inhibits transmission of service requests corresponding to the at least one failure condition while the at least one failure condition exists.

Abstract: Disclosed are systems and methods for reducing the amount of messaging between aerial vehicles and between controllers of aerial vehicles and simplifying aerial vehicle traffic management. In one implementation, a large service area, such as the United States, may be separated into a series of hierarchal regions. Rather than sending notifications to all agents (e.g., aerial vehicles, controllers) in the service area, each agent may subscribe to one or more regions of the hierarchal regions and only receive messages intended for the subscribed regions. In one example, as discussed below, messages for a particular region are only sent to agents subscribed to that region. Other agents within the larger service area do not receive the messages as they may not be relevant to those agents.

Abstract: Techniques for managing notifications may be described. In an example, the notifications may relate to an item and may be provided to a user device. An active device may be associated with the item. The active device may store a token for communication with a local area network associated with a location. Based on the communication, a determination may be made that the item may be in proximity to the location. Corresponding notifications may be sent to the user device.

Abstract: Systems and methods for improving the efficiency of order fulfillment are disclosed. When fulfilling an order in which substitutions are required, due to unavailability of particular products, the process of contacting the customer and receiving a selection from the customer can be separated from the picking process. The picker can continue to fulfill the order, while an automated system offers alternatives and receives selections from the customer. If appropriate, the substitution can be appended to the picker's list. If the picker has completed the remainder of the order, on the other hand, a new order with the substitution can be created, which can later be aggregated with the original order. A variety of methods can be used to efficiently present substitutions to the customer and receive choices from the customer, including use of imagery of substitute items.

Abstract: A system for providing dynamic code deployment and versioning is provided. The system may be configured to receive a first request to execute a newer program code on a virtual compute system, determine, based on the first request, that the newer program code is a newer version of an older program code loaded onto an existing container on a virtual machine instance on the virtual compute system, initiate a download of the newer program code onto a second container on the same virtual machine instance, and causing the first request to be processed with the older program code in the existing container.

Abstract: Techniques are described that enable a two-dimensional (2D) representation of three-dimensional (3D) virtual reality content to be generated and encoded. These techniques include modifying non-display pixels within the 2D representation to soften the transitions between display pixels and non-display pixels.

Abstract: A query optimizer may receive a query block that includes a hint. The hint may include a unique object identifier to specify an object to which the hint applies. In some instances, the object may correspond to a nested query block. A query optimization plan may be determined based, at least in part, on the hint. The query execution plan may then be executed to query a data store.

Abstract: Techniques are described for automatically identifying and inhibiting suspect electronic communications between users, such as for electronic communications that may reflect fraudulent activities by one or more of the users or that are otherwise inappropriate for one or more reasons. In some situations, the communications may relate to transactions in which the users are involved, such as for users that are buyers and sellers of items interacting via one or more electronic marketplaces. The communications may occur via a communication mechanism provided by an electronic marketplace that acts as an intermediary between the sender of a communication and the one or more intended recipients of the communication. The automatic identification of suspect communications that may be inappropriate includes automatically assessing the communications in one or more ways, and identified suspect communications and any associated inappropriate user activities may be inhibited in various ways.

Abstract: Digital content such as eBooks, music, video, personal files, and so forth stored in cloud storage resources are selectively transferred to an onboard storage device of a conveyance such as an aircraft, train, motorcoach, and so forth. Travelers may access the content from the onboard storage as if the cloud were still accessible.

Abstract: Described is a multiple-camera system and process for re-identifying an agent located in a materials handling facility based on anterior views of agents. An anterior view of a newly detected agent may be partitioned and color signatures generated for each partition. Likewise, stored anterior views of agents (candidate agents) that may potentially be the newly detected agent are partitioned and color signatures generated for each partition. Based on the color signatures, a similarity between the anterior view of the newly detected agent and the candidate agents is determined. The similarity may be used to either determine that the newly detected agent is one of the candidate agents or reduce the set of candidate agents that are considered during a manual review.

Abstract: An asset storage server is provided herein that assigns related files to an asset name and assigns permissions to the asset name such that related files with unrelated names can be assigned permissions independent of the file naming convention and without requiring a user to individually set the permissions of each file. The asset storage server may also generate modified versions of original file names and index a distributed object store based on the modified versions such that related files with related names are not listed in the same partition of the distributed object store. Indexing the distributed object store based on the modified versions of the original file names may reduce data retrieval latency.

Abstract: Systems and methods for providing access to a remote network via an external endpoint are provided. A client establishes a secure connection between an external endpoint and a remote network. Transmissions from clients to the external endpoint are supplemented with additional information regarding handling within the remote network, and then transmitted to an internal endpoint within the remote network. The internal endpoint processes the transmission based on the supplemental information and returns a response to the external endpoint. A response is then returned to the client. Access policies may be created by authorized users to establish processing of client transmissions. These policies may be stored and enforced by the internal endpoint or the external endpoint.

Abstract: A multilayered index is implemented for data stored in a data storage system. The multilayered index may include a granular index that specifies the location of specific files or abstractions within the data storage system, while a skip table specifies segments of the abstractions, and may point to both the granular index and the data storage devices of the data storage system. In redundancy coded systems, the use of multilayered indices may enable asynchronous retrieval of data during normal or adverse operation (such as during periods of varying data availability).

Abstract: A socket service may be used to implement client-defined function mappings (e.g., custom protocols) for sockets hosted by the socket service so that when a particular socket is opened for a particular client device, the socket operates according to a particular client-defined function mapping requested by the particular client device. To establish a particular client-defined function mapping, a socket manager may receive request from a user that specifies a particular endpoint (e.g., a client-registered function). When a client device requests a socket to be opened, the client device requests the particular client-defined function mapping to be associated with the socket. When the socket is opened, the endpoint is invoked. The particular client-defined function mapping may also specify one or more receive criteria for data received at the socket. If the one or more receive criteria is met, the endpoint is invoked by sending the data to the endpoint.

Abstract: Techniques are described for providing media presentations that include content originating from multiple sources in ways that are effectively transparent to end user devices. Manifest data provided to an end user device include a key encoded in the URL for each of the content fragments. The key encodes one or more interstitial periods of secondary content within the overall presentation of primary content. When a media server receives a content request from the end user device, the media server determines from the key encoded in the URL and the range of content requested whether the request corresponds to the primary content or the secondary content.

Abstract: Systems and methods provide a notification of a connectivity problem of a video doorbell to a smartphone. A first communication link between the video doorbell and a backend server is determined unavailable, such as when a password used by the video doorbell to access a local area network (LAN) is not accepted by the LAN. A Bluetooth transceiver of the video doorbell is activated and a Bluetooth signal transmitted from the smartphone is detected. A second communication link between the video doorbell and the smartphone via the Bluetooth transceiver is established and a message is sent to the smartphone, via the Bluetooth transceiver, indicating that the password used by the video doorbell to access the LAN is not accepted by the LAN. The message causes an application running on the smartphone to display a notification on a display of the smartphone indicating the communication problem.

Abstract: A hardware cipher module to cipher a packet. The cipher module includes a key scheduling engine and a ciphering engine. The key scheduling engine is configured to receive a compact key and iteratively generate a set of round keys, including a first round key, based on the compact key and determine, based upon a cipher mode indication and a type of ciphering whether to generate a key-scheduling-done indication after the first round key is generated and before all of the set of round keys are generated or to generate the key-scheduling-done indication after all of the set of round keys is generated. The ciphering engine is configured to begin to cipher the packet with one of the set of round keys as a result of receiving the key schedule done indication.
