Abstract: Technologies are disclosed herein for selecting and configuring metrics to monitor. The metrics available for monitoring are associated with computing resources provided by a service provider network. Instead of requiring a customer to manually determine the metrics that may be monitored, the service provider network may dynamically determine the metrics available for monitoring based on the infrastructure specified by the customer to execute in the service provider network. In this way, customers may not only select metrics related to the health of the computing devices (physical or virtual), the customer may also select metrics related to the software applications executing on the computing devices.

In one embodiments, a method for a client device for preventing redundant calls to an emergency call center is provided, the method comprising: receiving, at the client device, a notification, along with video footage associated with the notification, about an event generated by an A/V recording and communication device, the video footage captured by a camera of the A/V recording and communication device; receiving a request for contacting the emergency call center; informing one or more backend devices, in communication with the client device and a home security monitoring center that monitors a security system, of the received request to suppress a potential redundant call to the emergency call center from the home security monitoring center; and contacting the emergency call center.

Abstract: Printed circuit boards (PCBs) may include embedded lateral connectors. The embedded lateral connectors may be configured to enable components to quickly couple to or plug into a PCB, thus saving time to form connections. The embedded lateral connectors may also reduce weight and/or size by avoiding need for bulky tradition collections with conventional components (e.g., solders, external pin connectors, etc.). The connectors may include male connectors, female connectors, and/or mounting connectors. The connectors may be configured to connect multiple PCBs together, such as using a stacked configuration, which may enable reducing a volume of space needed in a housing for the PCBs.

Abstract: Techniques for analyzing recommendations may be described. In particular, an item offered from a network-based resource may be selected based at least in part on past orders for the item. Recommended items offered from the network-based resource may also be identified. A determination may be made as to whether the recommended items may include the item. Based on this determination, an indication of an issue associated with recommending the item may be generated. Based on the indication, a workflow to identify a potential cause of the issue may be initiated.

Abstract: An API provides a frontend interface to one or more backend services. Access to an API is controlled by a set of frontend credentials, and access to the one or more backend services is controlled by a set of backend credentials. A credential-translation table maintained within the API links each backend credential to one or more frontend credentials. Links between frontend and backend credentials may be managed by an administrator of the API. The API uses the translation table to translate frontend credentials provided with an API call into backend credentials used to access backend services. The API provides users with the ability to update the backend credentials in the credential-translation table based at least in part on the frontend credentials provided by the user. The API may limit the ability to extract backend credentials to administrative users.

Abstract: A system capable of synchronizing audio by determining a playback delay between when an audio sample is sent to and then output from a speaker. The system may generate a test signal configured to reach a saturation threshold and may send the test signal at a first time, followed by blank audio samples, from a first processor to a second processor to be output by the speaker. The second processor may detect that an audio sample exceeds a saturation threshold at a second time, generate a timestamp and send the timestamp to the first processor. The first processor may determine a playback delay between the first time and the second time and may also determine a number of blank audio samples sent between the first time and the second time. Using the playback delay and the number of blank audio samples, the system may generate audio using precise timing.

Abstract: A system and method for provisioning a volume and repartitioning a provisioned volume based at least in part on a workload. A request to provision a volume of a specified size is received, a first set of partition options is determined based at least in part on the specified size, and second set of partition options is determined based at least in part on one or more performance characteristics. A volume partitioning is determined based at least in part on an intersection of a number of partitions between the first set of partition options and the second set of partition options, and further based at least in part on a set of optimization criteria. Based at least in part on tracked usage of the volume or a repartition request, a determination is made to repartition the volume such that the partitioning scheme fulfills a set of optimization criteria.

Abstract: Systems and methods for determining item manipulation strategies using magnetic manipulation are described herein. For example, item information describing properties of an item may be accessed. The item information may indicate that the item includes a magnetic patch. Using this item information, a manipulation strategy for manipulating the item may be determined. The manipulation strategy may include a strategy for manipulating the item using one or more end effectors of a robotic manipulator. The manipulation strategy may be provided to the robotic manipulator for manipulation of the item by magnetically coupling an end effector of the one or more end effectors with the magnetic patch connected to the item.

Abstract: Techniques for providing category predictions may be provided. For example, a process may attempt to improve a user experience when the user provides a search query. The process can predict the category associated with the search query, even when the category is not a keyword in the search query. Once the category is determined, data may be provided for the particular category, including data that enables an adjustment of a user experience. For example, when the category is apparel, the user experience may include an image-heavy layout and, when the category is books, the user experience may provide more text.

Abstract: Disclosed are various embodiments for updating account data with multiple account providers. Account management logic determines that personal information associated with a user has been updated. Multiple accounts of the user that may use the personal information are determined. The accounts are with multiple account providers. Corresponding account update requests for the accounts are sent to the account providers. The account update requests specify the personal information that has been updated.

Abstract: Microwave interference mitigation techniques and systems are disclosed herein. In some embodiments, microwave interference mitigation involves coordinating wireless traffic in accordance with a magnetron's on-and-off cycle so that data is not sent during the magnetron's on period, and is exclusively sent during the magnetron's off period. Wireless traffic can be coordinated using a voltage monitoring and zero-crossing point detection technique coupled with a Clear To Send (CTS) packet. For non-microwave devices, wireless traffic coordination can be achieved using a pattern matching algorithm coupled with a Clear Channel Assessment (CCA) threshold adjustment during the magnetron's on-and-off cycles. Additional, or alternative, microwave interference mitigation techniques involve decreasing a maximum packet size for data packets that are to be transmitted wirelessly in the environment, which guarantees successful transmission of data packets during the magnetron's off periods.

Abstract: Techniques for encrypting short-term data using layered encryption based on difficult to obtain secrets are described herein. Data that will be encrypted is designated as the source data for a first iteration of a layered encryption. An index indicates a data block within a large set of random data. The data block is encrypted and the encrypted data block is combined with the source data for the iteration to produce set of cryptographic data for the current iteration. The set of cryptographic data is used to generate cryptographic key data that is used to encrypt the index and the encrypted index is stored. The set of cryptographic data is then used as the source data for the next iteration.

Abstract: Techniques for segmenting a network are described herein. Network locations in a network are grouped such that each group is disjoint with respect to all other groups. The grouping is based on a set of network communication event notifications. The network communication event notifications are used to determine internal and external dependencies for each group and the external and internal dependencies are used to segment the network.

Abstract: Method and apparatus for optimizing control of robotic systems. Failures of a robotic device performing a lifting operation for one or more items within a fulfillment center over a window of time are monitored. Responsive to the failures exceeding a predefined threshold number of failures for the window of time, one or more control operations for optimizing performance of the robotic device are determined, by processing environmental metrics, failure type, mode of operation and item type information as inputs to a trained machine learning model. A control system for the robotic device is configured based on the determined one or more control operations, and movement of the robotic device is controlled using the configured control system, to perform the lifting operation for one or more additional items within the fulfillment center.

Abstract: An elevated automatic transfer switch (ATS) cabinet provides power support redundancy to a set of electrical loads in one or more rack computer systems. The cabinet includes multiple-phase power feed input receptacles which each receive a multiple-phase power feed and distribute the separate phases of the power feed to separate ATS modules installed in the cabinet. Outputs from separate ATS modules can be distributed, via separate cabinet output receptacles, to electrical loads in one or more rack computer systems. Backup ATS modules can be installed in parallel with ATS modules, so that ATS modules can be replaced while maintaining power support. Particular bypass circuits in the cabinet can be selectively closed to bypass selected ATS modules with selected power feeds, based on manual interaction with one or more elements of the bypass circuit, including manual insertion of a conductive element into a slot element of the bypass circuit.
