Abstract: A misplaced user device deactivates processors and other resources so as to conserve residual battery power, while a radio frequency (RF) circuit remains active. The RF circuit transmits a beacon signal at time intervals to aid a user in locating and recovery of the misplaced user device by way of another user device operating in search mode. Information regarding the identity or other characteristics of the misplaced user device may be encoded in the beacon signal to assist in the search. The misplaced user device may modify the beacon signaling RF power, time intervals, information, or other parameters in response to an acknowledgement signal received from the searching user device.

Abstract: A data center can include an inflatable enclosure in which rack computer systems can be installed and can provide computing capacity. The inflatable enclosure includes an inflatable structure which is at least partially inflated based on cooling air discharged into the inflatable enclosure by one or more cooling modules. A cooling module can include a cooling system and a cooling air vent, where the cooling system adjustably induces a stream of cooling air and the cooling air vent adjustably directs the cooling air stream into a particular space enclosed by an inflatable structure. The inflatable enclosure can be established by separate modules positioned on opposite sides of a space and an inflatable structure which extends across the space between the modules. The inflatable structure can be extended over additional spaces to expand the inflatable enclosure, thereby providing additional space to install rack computer systems.

Abstract: Methods and apparatus for connection redistribution in load-balanced systems that include multiple load balancers each serving multiple nodes. In the connection redistribution method, each node estimates a connection close rate, which may be based on an estimation of the percentage of the overall client traffic received by the respective load balancer that is being handled by the node. The node generates close requests for connections between the respective load balancer and clients according to the connection close rate. The node sends the close requests to its load balancer, which forwards the close requests to the appropriate clients. Upon receiving a close request, a client may close the connection(s) indicated by the request, obtain a public IP address for a load balancer, and initiate new connection(s) to the respective load balancer via the public IP address.

Abstract: Pattern information may be associated with an item in an inventory to facilitate identification of the item from among other items in the inventory. The pattern information may represent a feature extrinsic to the physical appearance of the item and may be assigned to the item deterministically, randomly, or pseudo-randomly. An indicator of the pattern information, such as a tag or sticker, may be applied to the item or to its packaging to provide a visual aid to distinguish the item from other items in the same inventory or the item may be enclosed in additional packaging comprising an indicator of the assigned pattern information. Pattern information assigned to the item may comprise a single color, shape, pattern, or other attribute and may include other secondary pattern information. Different amounts of pattern information may be associated with different items or with the same item when co-located with other different items.

Abstract: A user who is authenticated to a system or service across a network can receive a token that includes a device fingerprint. The fingerprint can include information that is obtained from the client device through which the user supplied authentication credentials. The client device can be configured to include that token with subsequent requests. When a request is received, the information in the fingerprint can be extracted from the token and compared to information obtained from the device submitting that request. If the information matches within at least an allowable match threshold, for example, the request can be processed. If the information in the fingerprint does not match the current values of the device from which the request was received, the request can be denied or a remedial action performed.

Abstract: This disclosure describes, in part, systems, devices, and techniques to encrypt address resolution protocol (ARP) messages to prevent a rogue device from accessing information about a local network. In certain embodiments described herein, networked devices are preconfigured with security credentials that allow the devices, possibly via network interface controllers (NICs), to encrypt outgoing ARP messages and decrypt incoming ARP messages. The NICs may listen for encrypted messages that are recognized as being ARP messages. These encrypted messages may include a designator that indicates that the message is an encrypted ARP message. When a NIC receives a message that is indicated as an encrypted ARP message, then the NIC will decrypt the message using secure credentials to obtain the true ARP message. The device will then process the message in accordance standard procedures.

Abstract: Various types of content can be displayed through an interface of a computing device. Portions of this content, such as words or alphanumeric characters, can have a visual identifier displayed proximate those portions. The identifiers can indicate the availability of additional content, such as one or more alternative spellings or corrections, links to additional information, alternative views, and links to contact information for a name in an address book. In one example, a default viewing orientation of the computing device can be determined for a user viewing the content on the interface. Upon detecting a rotation of the computing device, a banner or other graphical element is displayed for each of the displayed portions that are associated with a visual identifier on the interface. Accordingly, a user can select one of those elements to receive the additional information.

Abstract: Uncrewed autonomous vehicles (“UAVs”) may navigate from one location to another location. Described herein are systems, devices, and methods providing countermeasures for threats that may compromise the UAVs. A plurality of UAVs may establish a mesh network to distribute information to one another. A first UAV may receive external data from a second UAV using the mesh network. The external data may be used to confirm or cross-check data such as location, heading, altitude, and so forth. Disagreement between data generated by the first UAV with external data from the second UAV may result in the determination that the first UAV is compromised. Remedial actions may be taken, such as the first UAV may be directed to a safe location to land or park, may receive commands from another UAV, and so forth.

Abstract: The systems and techniques described herein optimize processing of requests, such as external requests, internal requests or inter-service requests.

Abstract: A compute instance of a virtual computing service (VCS) is assigned first and second cryptographically verifiable identities (CVIs) within respective namespaces. A cryptographic key pair associated with the first CVI includes a non-transferable private key managed by a secure key store which does not permit the private key to be copied. The VCS enables the instance to use the private key for asserting the CVIs. In response to a first identity query, the instance indicates the first CVI. In response to a second identity query, the instance indicates the second CVI.

Abstract: A camera on a computing device can capture a plurality of images, each with a different exposure setting but having the same subject. The images can be stored, at least temporarily, in a memory device on the computing device. The device can determine a time subsequent to the capturing of the images at which to process the plurality of images. For example, the time can be when the camera is not being used and/or when the computing device has sufficient resources (e.g., processing power, battery life, etc.) to process the plurality of images. At the determined time, the computing device can process the plurality of images to generate at least one high dynamic range (HDR) image. The processing of the plurality of images to generate the at least one HDR image can be based at least in part upon combining at least some portions of the plurality of images.

Abstract: A base device may work in conjunction one or more peripheral devices to capture audio from different locations within a room. The peripheral devices may include a companion device and an accessory device, either or both of which may be present in a given situation or deployment. The base device is configured to communicate with the companion device using a first wireless communications protocol and with the accessory device using a second wireless communications protocol. When both of the companion and accessory devices are present, however, the companion and accessory devices communicate with each other using the second wireless communications protocol and the companion device relays communications between the base device and the accessory device. This avoids the need for the base device to use the second wireless communications protocol and reduces contention for shared resources by the base device.

Abstract: A system, method and computer-readable medium for request routing based on prioritization and load information are provided. A client request processing a resource identifier for requested content transmits a DNS query to a content delivery network service provider. Based on a content provider identifier included in the DNS query, a receiving DNS nameserver determines a selection from a hierarchical organization of POPs and the relative capacity for a selected POP to process a subsequent request for resources. Based on the processing of the prioritization information and load information, the receiving DNS nameserver resolves the DNS query.

Abstract: Techniques are described for providing users with access to computer networks, such as to enable users to create and configure computer networks that are provided by a remote configurable network service for the users' use. Computer networks provided by the configurable network service may be configured to be private computer networks that are accessible only by the users who create them, and may each be created and configured by a client of the configurable network service to be an extension to an existing computer network of the client, such as a private computer network extension to an existing private computer network of the client. In addition, access to remote resource services may be configured and provided from such computer networks in various manners, such as to automatically include access control information to limit access to particular resources to computing nodes at the location of that provided computer network.
