Abstract: Described herein is a system for enabling a user to perform complex goals using multiple skills/applications of an intelligent assistant device. Skills may register as consumers of an action or providers of an action, and the consumer skills may be configured to invoke provider skills to perform actions. The system receives a request to perform an action from a skill along with some action data. The system validates the action data, selects another skill to perform the action, and forwards the request to the selected skill to perform the action.

Abstract: A storage node of a database replica group may distribute different portions of data in local storage and external storage, where local storage and external storage are organized using different types of index structures. Responsive to receiving an access request for a database, a storage node may determine that an item of the database to be accessed by the request does not reside within a first portion of the database stored locally at the storage node. Responsive to this determination, the storage node may obtain from an external storage service a second portion of the database, the second portion including a plurality of items including the item, and the second portion organized according to a structure different from the first portion. The storage node may then store the plurality of obtained items in the first portion and process the request using the first portion of the database.

Abstract: A rack for a datacenter or other environment may define an internal width configured to receive rack-mounted units of a predetermined width. An adapter may enable operation with a computing appliance having a maximum width smaller than the predetermined width. The adapter can include a tray with a footprint having the predetermined width and a mount for supporting the computing appliance within the footprint of the tray. The tray may support a power inverter that receives from a direct current power supply and provides alternating current to the computing appliance. The tray may also support a patch panel having a network port accessible from a front of the tray. The patch panel can be communicatively coupled with the computing appliance to provide networking communication with the computing appliance through the second network port.

Abstract: Secure operations can be performed using security module instances offered as a web service through a resource provider environment. State data and cryptographic material can be loaded and unloaded from the instance as needed, such that the instance can be reused for operations of different customers. The material and data can be stored as a bundle encrypted using a key specific to the hardware security module and a key specific to the resource provider, such that the bundle can only be decrypted in an instance of that type of security module from the associated manufacturer and operated by that particular resource provider. The customer is then only responsible for the allocation of that instance during the respective cryptographic operation(s).

Abstract: Techniques for performing audio-based device location determinations are described. A system may send, to a first device, a command to output audio requesting a location of the first device be determined. A second device may receive the audio and send, to the system, data representing the second device received the audio, where the received data includes spectral energy data representing a spectral energy of the audio as received by the second device. The system may, using the spectral energy data, determine attenuation data representing an attenuation experienced by the audio as it traveled from the first device to the second device. The system may generate, based on the attenuation data, spatial relationship data representing a spatial relationship between the first device and the second device, where the spatial relationship data is usable to determine a device for outputting a response to a subsequently received user input.

Abstract: Described are systems and methods directed to generation and subsequent update of a dimensionally accurate body model of a body, such as a human body, based on two-dimensional (“2D”) images of at least a portion of that body and/or face images of a face of the body. A user may use a 2D camera, such as a digital camera typically included in many of today's portable devices (e.g., cell phones, tablets, laptops, etc.) to produce body images that are used to generate a body model of the body of the user. Subsequently, the body model may be updated based on a face image of the face of the user, without requiring the user to provide another body image.

Abstract: A metadata catalog may store metadata about data sources. The metadata may define table, column, partition and/or data formats, as well as title information, textual descriptions, modification information, data schemas and access information, such as location and connection information. A metadata catalog service may provide a shared, persistent, central repository for the metadata. The metadata of the catalog may be published via multiple access mechanisms and programmatically obtained and processed by other programs via the metadata catalog service. Metadata consumers may utilize the metadata catalog service to perform various metadata tasks, such as metadata retrieval, creation, addition, modification and/or deletion. The metadata catalog service may be directly integrated into existing data analytic tools as a persistent and durable metadata store allowing users to utilize the broad set of data processing tools.

Abstract: Technologies for mesh path selection are described. One method of operating a first wireless mesh device includes determining, using first client information about a first link, a first metric representing airtime usage on the link, and a second metric representing a first amount of data on a second link, the second link using the first frequency band. The method determines a third metric on a third link, the third link using a second frequency band. The method determines, using the metrics, a first throughput associated with a first path with the second link and a second throughput associated with a second path. The method determines that the third link results in better throughput and sends or receives first data on the third link.

Abstract: A softAP bridge is created to support a mesh network that also works seamlessly with any home Wi-Fi AP routers by using Layer-3 techniques to simulate a Layer-2 bridge. With this softAP bridge, Wi-Fi chipsets with integrated special Wi-Fi MAC Layer-2 mesh network support (e.g., 802.11s), or external gateway hubs, are not required. To accomplish this solution, one of the wireless devices may be designated as a relay device for communicating IPv6 data packets between a home AP router and the remaining wireless devices designated as client devices.

Abstract: Electrical faults pose a significant risk to people and property. A system is described that deploys instrument devices with sensors to detect faults within an alternating current (AC) electrical distribution system. These sensors may detect electrical, optical, thermal, acoustic, radio frequency, and other phenomena associated with a fault. Data from different sensors may also be used to distinguish fault and non-fault status. Users are notified if a fault status is detected. Mitigating actions may be automatically taken, such as de-energizing a branch circuit associated with the fault status. Information about non-fault status may also be used to mitigate nuisance circuit breaker interruptions. In some situations, a nuisance interruption of a breaker may be automatically reset if all instrument devices connected to the breaker reported non-fault status before the interruption.

Abstract: Some devices may perform processing using machine learning models trained at a centralized system and distributed to the device. The centralized system may update the machine learning model and distribute the update to the device (or devices). To reduce the size of an update, the centralized system may train a model update object, which may be smaller in size than the model itself and thus more suitable for sending to the device(s). A device may receive the model update object and use it to update the on-device machine learning model; for example, by changing some parameters of the model. Parameters left unchanged during the update may retain their previous value. Thus, using the model update object to update the on-device model may result in a more accurate updated model when compared to sending an updated model compressed to a size similar to that of the model update object.

Abstract: Reliability monitoring can be performed for compute instances in a cluster with auto-scaling capability. Such monitoring can analyze state information for various instances, such as spot instances, to determine when an interruption or termination is to occur. An impact assessor can determine the impact on performance due to any such interruption or termination, and if necessary to maintain at least a minimum level of performance then an action performer can obtain additional or alternate instances, which may be of a different type, to make up for lost capacity. Any tasks being performed can be migrated to the newly-allocated instances without any failures or significant impact on performance, and the previously-utilized instances can be released corresponding to the termination or interruption.

Abstract: A speech interface device is configured to receive response data from a remote speech processing system for responding to user speech. This response data may be enhanced with information such as a remote ASR result(s) and a remote NLU result(s). The response data from the remote speech processing system may include one or more cacheable status indicators associated with the NLU result(s) and/or remote directive data, which indicate whether the remote NLU result(s) and/or the remote directive data are individually cacheable. A caching component of the speech interface device allows for caching at least some of this cacheable remote speech processing information, and using the cached information locally on the speech interface device when responding to user speech in the future. This allows for responding to user speech, even when the speech interface device is unable to communicate with a remote speech processing system over a wide area network.

Abstract: Techniques for voice-based interactions are described. In an example, a device presents a user interface on a display. The device starts an operational mode of the device. The operational mode restricts voice-based interactions with the user interface to a set of commands. The set of commands is defined in a language model that is stored on the device. Further, the device receives, at a microphone of the device, audio data corresponding to a natural language utterance and generates, from the audio data, text data that corresponds to the natural language utterance. The device determines, based at least in part on the language model, that semantics of the text data correspond to a command from the set of commands and presents, on the display, an outcome of performing the command.

Abstract: Systems and methods for contextual device pairing are disclosed. For example, when certain user input indicating intent to cause a first device to transition to a pairing mode is received, the first device may broadcast a non-bondable signal with an identifier of the first device. When a second device receives the non-bondable signal, that second device may send response data, which may be received at the first device. The first device may analyze the response data to determine whether a context associated with the first device and/or the second device indicates desirability to transition to the pairing mode.

Abstract: Change data capture is performed asynchronously for direct transfer to a stream processor. When updates to a database as part of database transactions are performed, a transaction log is generated that describes the database transactions. The transaction log may be evaluated to determine indications of changes included in the database transactions. The indications of the changes may be stored in memory according to the database transactions that include the indications of the changes. When a database transaction is determined to be committed to the database, the change indications may be sent directly from the memory to the stream processor.

Abstract: An optical switch configuration is disclosed that gives the appearance of a logical cut in a fiber optic line. The inputs to the optical switch are redundant so that if a fiber event occurs on one input, the optical switch can switch to the other input. In the case where both paths of an optical fiber have fiber events, router convergence is delayed. One mechanism to mitigate a prolonged fiber degradation is to dampen the optical power on the output optical fiber of the optical switch, such that it creates a loss of light and appears as a clean cut of the optical fiber. Another solution uses optical switches to inject an alternate light source onto the output optical fiber, wherein the alternate light source is of a wavelength to be filtered out giving an appearance of a clean cut of the optical fiber.

Abstract: A system may use sensor data from a facility to generate tentative values associated with an event, such as the identification of an item removed from a shelf of the facility. A confidence value associated with each of the tentative values may be less than a confidence threshold. In response, inquiry data seeking confirmation of a tentative value from an associate is generated and sent to one or more associates in the facility. Responses from the associates are collected to determine a selection of one of the tentative values. The selected tentative value is designated as output data for the system. Thereafter, the output data and the original sensor data are designated as training data, which can then be used to train or update machine learning systems. Subsequent use of the updated machine learning systems can yield more accurate results.

The computer system sends the package decision to the workstation.

Abstract: Network devices, such as load balancers may be configured to forward client metadata to back-end nodes using defined fields of a security protocol. For example, client metadata may be inserted into an extension field or certificate defined by a security protocol that is used for a secure connection between the load balancer and the back-end node. In some instances, a source IP address based on a received request may be inserted into the extension field or certificate defined by the security protocol before the request is forwarded to the back-end node. The back-end node may extract the client metadata and use the client metadata for any of a number of processes (e.g., billing, tracking, security, logging, etc.).

Abstract: A coherent connection and a non-coherent connection are provided between system-on-chips (SoCs). The coherent connection can be coupled to coherent interconnects on the SoCs, and the non-coherent connection can be coupled to non-coherent interconnects on the SoCs.

Abstract: Updates to projected data subsets may be ordered using conditional operations. When updates to a data set are received, a determination is made according to a schema for a projected subset of the data set as to whether the update is to be propagated to the projected subset of the data set. If the update is to be propagated, a comparison of a version identifier for the update may be made with a version identifier for the subset to determine whether performance of the update is consistent with an ordering of updates performed to the first data set. If the comparison indicates the performance of the update is consistent, then the update may be performed to the projected subset. If not, then the update may not be performed.

Abstract: An IoT service of a provider network may be used to provision edge devices with duplicate device identifiers for edge devices that use a radio communication protocol (e.g., LoRaWAN). This may allow a service provider to accept legitimate registration requests from edge devices instead of automatically rejecting them. When the IoT service receives a registration request, the service determines whether there are other devices registered with the same device ID. If so, then the service determines whether to accept or reject the request. For example, the service may determine whether the number of duplicate device IDs being used for registered devices will remain within a predefined threshold if the device is registered. If so, then the service registers the device. Otherwise, the service rejects the request.

Abstract: Recent location and control information received from “lead” vehicles that traveled over a segment of land, sea, or air is captured to inform, via aggregated data, subsequent “trailing” vehicles that travel over that same segment of land, sea, or air. The aggregated data may provide the trailing vehicles with annotated road information that identifies obstacles. In some embodiments, at least some sensor control data may be provided to the subsequent vehicles to assist those vehicles in identifying the obstacles and/or performing other tasks. Besides, obstacles, the location and control information may enable determining areas traveled by vehicles that are not included in conventional maps, as well as vehicle actions associated with particular locations, such as places where vehicles park or make other maneuvers.

Abstract: This disclosure describes systems and techniques for detecting events, determining a result of each respective event using a first hypothesis source, and calculating a likelihood that a second (and/or additional) hypothesis source would determine the same result of the respective event.

Upon completion of an account creation procedure or an account configuration procedure at a service provider network, a system may automatically (e.g., absent additional manual inputs) integrate the new account and/or the account configuration with the third-party application, for instance, such that the new account and/or the account configuration is replicated across multiple cloud accounts managed by the third-party application. The service provider network may comprise an organization account creator, an account configurer, an event monitor for detecting an account-related event (e.g.

Abstract: First video data representing performance of an activity by a first user is acquired. Poses of the first user are determined from the first video data. Second video data is generated based on the determined poses and based on appearance data that represents a second user, such as a model, paid performer, and so forth, in various poses. The resulting second video data depicts the second user performing the same poses as the first user. The second video data may then be sent to a recipient. For example, a participant in an exercise class may send a video to an instructor that depicts what appears to be the paid performer performing the poses, instead of the participant. As a result, video data showing the participant is not shared, protecting the privacy of the participant while still allowing them to participate and interact.

Abstract: A wearable device has a housing containing electronics and a band that retains the wearable device on a user's arm. Each end of the housing has an open receptacle. The band has protrusions made from an elastomeric material and includes a rigid member arranged at least partially within. The protrusions are inserted into the receptacle to attach the band to the housing. A lower portion of the housing comprises two pieces that, when assembled, provide optical baffles between adjacent optical devices such as a heart rate monitor, and windows for the optical devices to operate. A thermal conductor is retained between the two pieces and facilitates operation of a temperature sensor in the device. An antenna carrier facilitates installation of an antenna without impairing fixation of an upper portion of the housing. A compact charger clips to the housing to supply power to recharge a battery in the wearable device.

Abstract: Fair queuing of request tasks spawned by requests to execute generative operations such as, for example, graph query language requests to execute a graph query language query, mutation, or subscription operations. Queuing techniques are used to prevent a heavy generative operation from dominating usage of computing resources of a host that executes many generative operations concurrently including a mix of heavy and normal generative operations. Generative operations are analyzed and classified as heavy or normal as the request tasks they spawn are being executed. If a generative operation is classified as heavy, then subsequent request tasks spawned by the heavy generative operation are added to an overload queue while request tasks spawned by concurrently executing normal generative operations as added to a main queue. For fairness, request tasks are polled from the main queue for execution at greater frequency than request tasks in the overload queue.
