Additionally, in some cases, the bandwidth estimation techniques disclosed herein may, for example, capture cross traffic and its effects on bandwidth. Furthermore, in some cases, the bandwidth estimation techniques disclosed herein may, for example, employ dynamic self-correcting techniques for more reliable estimates.

Abstract: Systems and methods for routing pages to cellular phones (UE) not connected to a cellular network, but connected to a wireless local area network (I-WLAN), are disclosed. The system can route cellular pages to disconnected cellular devices using 3GPP AAA components, such as a Third Generation Partnership Project authentication, authorization, and accounting (3GPP AAA) server. The system can route pages via a home location register (HLR) connected to the I-WLAN or a mobile switching center (MSC) connected to the I-WLAN. The system can determine an appropriate MSC based on proximity of the MSC to the last known location of the UE, for example, or based on the MSC with the lowest utilization rates. The system can send a page to the UE via the I-WLAN instructing the UE to reconnect to the cellular network. The system can then send cellular data to the UE using the cellular network.

Abstract: Systems and associated processes for generating user attribute interest data and using that data to present and/or develop reviews of items are described herein. These systems and processes can dynamically collect data on a user's interest in specific item attributes from the user's interaction with an electronic catalog and can store this data in association with the user. This data may be used to provide users with a personalized set of reviews which will provide the user with information relevant to interesting item attributes. Further, this data may be used to display a set of dynamically generated statements and/or questions that prompt users to write an item review on specific item attributes. Accordingly, user attribute interest data can potentially both present and elicit more thorough and useful feedback than existing review systems in some embodiments.

The message envelope comprises a plurality of field names and one or more field values formatted using an envelope schema. A different message is generated comprising a different message envelope and the different event. The different message envelope comprises the field names and one or more different field values formatted using the envelope schema. The message is filtered based at least in part on the message envelope, and the different message is filtered based at least in part on the different message envelope.

Abstract: A database system may include a database service and a separate distributed storage service. The database service (or a database engine head node thereof) may be responsible for query parsing, optimization, and execution, transactionality, and consistency, while the storage service may be responsible for generating data pages from redo log records and for durability of those data pages. For example, in response to a write request directed to a particular data page, the database engine head node may generate a redo log record and send it, but not the data page, to a storage service node. The storage service node may store the redo log record and return a write acknowledgement to the database service prior to applying the redo log record. The server node may apply the redo log record and other redo log records to a previously stored version of the data page to create a current version.

Abstract: A computing system that provides virtual computing services may generate and manage remote computing sessions between client computing devices and virtual desktop instances hosted on the service provider's network. A computing resource instance manager may monitor connections to and disconnections from a virtual desktop instance during particular time periods, and may apply a resource management policy to determine whether and when to shut down an underlying virtualized computing resource instance following a disconnection (e.g., immediately, after some period of time, or only between certain hours). A storage volume for the virtual desktop instance may be detached during a shutdown. In response to a reconnection request, the virtualized computing resource instance (or another such instance) may be restarted and the storage volume may be reattached. The computing resource instance manager may develop a model for predicting when to shut down or restart an instance based on historical data or machine learning.

Abstract: A connection request from a client is received at an access subsystem node of a distributed storage service. The connection request includes an attempt count parameter indicative of a number of times an establishment of a connection on behalf of the client has been attempted. A workload threshold level based on the attempt count parameter is identified for use in an acceptance decision for the connection request. In response to a determination that a local workload metric of the access subsystem node is below the workload threshold level, the connection is accepted.

Abstract: An inventory system can include radio frequency identification (RFID) tags and RFID tuners that can be brought into interacting proximity with one another to provide input or other information about the location or other condition of movable elements within the inventory system. A wearable accessory that is wearable by a human operator can include RFID tuners thereon for interacting with RFID tags on other elements of the inventory system in order to communicate details about the elements and facilitate functions of the inventory system.

Abstract: Partitions of a hosted computing service may be maintained on a computing node. Processing of requests to access the partition may be limited to constrain capacity utilization to a provisioned amount of capacity reserved for the partition. A second, additional amount of capacity may be associated with the partition and may reflect potential future changes to the provisioned amount of capacity. A sum of provisioned and additional capacities associated with partitions on a computing node may be calculated. The computing node may be ranked, relative to other computing nodes, for maintaining new or relocated partitions based on the sum.

Abstract: This disclosure is directed to a single blade propeller and systems, devices, and techniques pertaining to assisting in critical stages of flight (e.g., takeoff, landing, emergency situations, etc.) in vertical takeoff and landing (VTOL) aircraft. The single blade propeller may be incorporated into fixed and rotary wing VTOL aircraft as part of a first propulsion system. The first propulsion system may include one or more single blade propellers driven by electric motors, combustion engines, and/or hybrid engines. Each of the single blade propellers may include a lift-producing blade and a counterweight opposite the lift-producing blade. As each of the single blade propellers spins, it may produce lift in a direction approximately perpendicular to the horizon to effect vertical flight.

It is determined whether the network traffic complies with a rule established by the organization. An action is implemented in response to determining that the network traffic does not comply with the rule.

Abstract: Features are disclosed for using a neural network to tag sequential input without using an internal representation of the neural network generated when scoring previous positions in the sequence. A predicted or determined label (e.g., the highest scoring or otherwise most probable label) for input at a given position in the sequence can be used when scoring input corresponding to the next position the sequence. Additional features are disclosed for training a neural network for use in tagging sequential input without using an internal representation of the neural network generated when scoring previous positions the sequence.

Abstract: An audio-based system may perform echo cancellation using first and second adaptive filters. An adaptation controller may be configured to control whether and/or how the filter coefficients of the first adaptive filter are updated, based on detected filter divergence, echo path changes, and/or presence of near-end user voice. The parameters of the second adaptive filter may be copied from the first adaptive filter under certain conditions that indicate whether copying the parameters would be likely to improve echo suppression.
