Abstract: A computer-implemented method includes receiving, at a microphone of a voice-controlled device, a speech input, generating an electrical signal having a first gain level that is below a gain threshold for audible detection by a user, transmitting the electrical signal to the speaker and detecting, by the microphone, an audio signal that includes a combination of ambient noise and a probe audio signal, wherein the probe audio signal is output by the speaker based on the electrical signal. The method further includes determining a power level of the probe audio signal and determining a state of the display based on the power level of the probe audio signal.

Abstract: Techniques described and suggested herein include systems and methods for updating, adding, deleting, managing, and otherwise manipulating instance data across multiple virtual instances in an addressable fashion. For example, a customer may control or otherwise be associated with a fleet of virtual instances running on one or more hosts of a computing resource service provider. The described techniques enable customers, or other entities, to update instance data related to arbitrarily defined groups of the fleet using, e.g., tags or other common identifiers, so as to, e.g., alter operational characteristics of some or all of a given fleet of virtual instances without necessitating individual alteration of each instance.

Abstract: This disclosure describes RFID tags configured to fracture when heated, such as when exposed to threshold levels of electromagnetic energy. In some instances, the RFID tags include materials that expand when heated for the purpose of stressing metal antenna traces of the RFID tags. When under stress from these expansion materials that bond to the antennas (e.g., thermoplastics), these antennas may fracture, thus lessening the risk that the dangerous arcing will occur from the electromagnetic energy, such as when an item and corresponding tag are placed in a microwave oven.

Abstract: Methods, systems, and computer-readable media for replication event ordering using an external data store are disclosed. Events are received for a key in a source data store, including a deletion event and modification events. In an external data store, a record of the deletion event is stored that includes a sequence identifier of the deletion event in a sequence. Sequence identifiers are assigned to the modification events. Some of the sequence identifiers are earlier than the deletion event in the sequence, and others of the sequence identifiers are later than the deletion event in the sequence and are assigned based at least in part on the record of the deletion event in the external data store. Individual events are replicated or not replicated to the destination data store based at least in part on their sequence identifiers.

Abstract: Techniques for a secure and flexible distributed job processing between a transaction network of a service provider and a processing endpoint of an entity are described. In an example, a transaction instrument may be used for a transaction and may be registered with the processing endpoint based on a transaction account. The transaction network may store an ownership object associating a token corresponding to the transaction instrument, a user identifier unique to a user account, and a provider identifier unique to the transaction account. The transaction network may identify a membership status of the user account and may customize the transaction based on this status. The transaction, as customized, may be completed by sending the provider identifier and data about the customization to the processing endpoint.

Abstract: Techniques for enabling a device to send to a speech processing server further input audio data following a completed utterance dialog to prevent the need for subsequent keywords to be spoken to invoke subsequent commands are described. A system receives input audio data corresponding to an utterance from a device upon the device detecting speech corresponding to a keyword. The system performs speech processing on the input audio data to determine a command. The system determines output data responsive to the command and sends same to the device, thus completing operations regarding the utterance. The system may also send an instruction to the device to: send to the system further input audio data corresponding to further input audio without the device first detecting a wake command.

Abstract: Methods, systems, and computer-readable media for customizable event-triggered computation at edge locations are disclosed. A request for content is received at an edge server from a client device. The content is sought from a content cache at the edge server or from an origin server coupled to the edge server. Processing of the request is initiated, comprising encountering an event. The event is associated with a function specified by a customer. The function associated with the event is executed at the edge server using process isolation. The content is generated based at least in part on execution of the function. The content is sent from the edge server to the client device.

Abstract: An actuator for a suction-cup end effector bends or deforms in response to air pressure within bladders in the actuator. Air bladders of the actuator apply bending moments to rigid flange structures, which transmit the moments to a base layer of the actuator. Grasping elements may be used.

Abstract: Customer interactions with one or more pages associated with an online marketplace may be aggregated into historical navigational patterns, which may be associated with one or more items available for purchase at the online marketplace. Where a series or sequence of customer interactions is subsequently received from a customer, such interactions may also be aggregated into a pattern, which may be compared to one or more of the historical navigational patterns. An item recommendation may be identified for the customer based at least in part on the comparison of the received navigational pattern to one or more of the historical navigational patterns. The item recommendation may include an item previously purchased following one of the historical navigational patterns, or an item related to one or more such items.

Abstract: A hub device or edge device implements adaptive data compression. The model training service analyzes the received data. A machine learning model of the hub device receives time-series data from one or more data sources and classifies respective portions of the time-series data as respective patterns. A data compressor at the hub device generates compressed data by applying different compression techniques to the respective portions of the time-series data according to a mapping of the compression techniques to the respective patterns. The hub device then transmits the compressed data to an endpoint for processing (e.g., another device that uses the compressed data). The hub device receives feedback for the compressed data. In response to the feedback, the hub device changes one or more of the compression techniques that are mapped to the respective patterns.

Abstract: A power distribution grid for a facility, such as a data center, is located within the facility. The power distribution grid includes a plurality of power transport elements arranged in a grid pattern and nodes located at intersections of the grid pattern. Electrical loads are supplied power via respective nodes of the power distribution grid. Also, each node is supplied power from more than two transport elements, such that one or more transport elements can fail and electrical loads connected to a particular node associated with the failed transport elements continue to receive electrical power supplied to the particular node from at least two different transport elements.

Abstract: At a data management service, a child template associated with a parent group of one or more cells of a first data sheet is stored. In response to detecting that a parent cell has been added to the parent group, a particular child data sheet is instantiated automatically in accordance with the template. In response to a change to a value in a first cell of the child data sheet, a corresponding value of a cell of the first data sheet is modified.

Abstract: Methods, systems, and computer-readable media for safe deployment of configurations to server fleets are disclosed. A host processes requests to a service according to a control versions of a first configuration and a second configuration. After receiving an experimental version of the first configuration, a host processes some requests to the service according to the control versions of the first configuration and the second configuration, and other requests according to the experimental version of the first configuration and the control version of the second configuration. The experimental version of the first configuration is approved or rejected based at least in part on performance of the service. The host then processes some requests to the service according to the experimental version of the first configuration and the control version of the second configuration, and other requests according to the experimental versions of the first configuration and the second configuration.

Abstract: This application describes techniques for determining a constituency and a layout of a group of devices within an environment. By determining the devices that form the group, as well as the positions of these devices relative to one another, the group of devices may be used to more intelligently output content within the environment.

Abstract: Systems, methods, and devices for establishing communications sessions with contacts are disclosed. In some embodiments, a first request may be received from a first device. The first request may be to communicate with a contact name. A user account associated with the first device may then be identified, and a contact list associated with the user account may be accessed to determine contacts associated with the contact name. Based on the contact list, a first contact and a second contact associated with the contact name may be identified. It may be determined, from memory, that the first contact is a first preferred contact. However, based on an intervening event, the second contact, rather than the preferred contact, may be selected for communicating with the contact.
