Abstract: A robotic system, a manipulator, and a method for cooling actuators are defined. The robotic system can include an actuator of a manipulator, an end effector (e.g., a suction end effector) operably coupled to the actuator, a supply line configured to supply air to the end effector, and a cooling sleeve coupled to the actuator. The end effector can be actuated by the air. The cooling sleeve can include (i) a heat exchange surface (e.g., made of copper) in contact with the actuator, (ii) an inlet, and (iii) an outlet. The cooling sleeve can be configured to receive the air from the supply line via the inlet, to pass the air over the heat exchange surface, and direct the air out of the cooling sleeve via the outlet.

Abstract: Compact hosting of database query processors is performed using virtualization snapshots. When a request to access a database is received via a previously established connection from a client for an idle query processor that is not currently executing, a virtualization snapshot may be identified that is associated with the idle query processor. The virtualization snapshot of the query processor may be used to restore the query processor into virtual execution on a host system for the database using an origin snapshot that shares clean pages across multiple query processors on the host system. The request may be performed by the restored query processor in virtual execution on the host system.

Abstract: A device includes a general purpose input/output (GPIO) pin and a chipset that has a bootloader component, a secure driver component, and a countermeasure handler component. The bootloader component loads an intrusion detection (ID) configuration for detecting intrusion events at the device, authenticates the ID configuration, and initializes the countermeasure handler component. The secure driver component receives, from the GPIO pin, an electrical signal associated with a hardware interrupt at the device and causes a notification to be provided to a user associated with the device. The counter secure driver component also perform at least one countermeasure in response to the intrusion event.

Abstract: Systems and methods for intelligent defaulting using machine learning are provided. The systems and methods may involve the use of one or more machine learning models that are used to determine a default shipment option to present to a user through a user interface associated with a product checkout page (for example, on a website or through a mobile device application).

Abstract: A serverless computing system executes user-submitted code in sandboxed environments such as virtual machines or containers. To support execution of parallel applications that require data transfer between instances of the application, the serverless computing system implements an ephemeral mesh network that allows instances of the parallel application to communicate with each other while executing in their respective sandboxes. In some embodiments, a controller or parent application may also connect to the ephemeral mesh network to coordinate execution of the parallel applications. In other embodiments, the parent application may be external to the serverless computing system. The serverless computing system may connect and disconnect sandboxed environments from the ephemeral mesh network as parallel applications start and stop executing, and may remove the network and terminate the parallel applications when the parent application stops executing.

Abstract: Described are systems and methods for in-facility purchase of items from a single seller when those items are offered for sale by multiple sellers. For example, a materials handling facility may include two or more sellers (Seller A and Seller B) that offer items for sale within the facility. A user may pick items from Seller A and items from Seller B and complete an in-facility purchase of those picked items from one of the sellers, such as Seller B, by payment of the purchase price and applicable taxes to that seller. At a subsequent time, for example when the user exits the facility, Seller B may pay Seller A at least a portion of the purchase price for the Seller A items sold by Seller B as part of the in-facility purchase.

Abstract: Various embodiments of transcoding system that includes a pre-filtering system are disclosed. The pre-filtering system includes amorphous sub-filter modules and is configured to automatically configure a sequence of filter modules to be used to filter a given segment of a media object being transcoded based on artifacts resulting from an earlier decoding process.

Abstract: Embodiments of a content recommendation or selection system are described. The system uses a pipeline of machine learning models to select content for a user. In embodiments, a first user model generates a first score of content categories for the user based on short-term user data. A second user model generates a second score of the categories for the user based on long-term user data. The two scores are combined to select the categories to include on the content user interface. In embodiments, new categories are added to the recommendations based on an exploration-exploitation algorithm. In embodiments, content categories are organized on the user interface in a manner to promote neighborhood diversity. Advantageously, the machine learning pipeline enables independent configurability of various objectives of the content recommendation or selection system and reduces the amount of machine learning resources needed to implement the system.

Abstract: A codec system dynamically selects a codec from multiple available codecs with a highest level of encoding quality at a computing device based at least in part on the available computing resources at a particular computing device. The codec system can continuously monitor encoding performance and if encoding with the selected codec uses too many computing resources, then the codec system can switch to a codec that uses fewer computing resources.

Abstract: The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. One or more computing devices can install malware code into a network device after exploiting a vulnerability of the network device. A monitoring and mitigation service can monitor network devices and detect malware code installed on the network-based service. The monitoring and mitigation service can identify the internet protocol (IP) address or any routing information regarding the computing devices that sent the malware code. Based on the identified information, the monitoring and mitigation service can identify and implement the network mitigation information in the form of null routing addresses that will cause network communications associated with the identified computing device to be terminated or otherwise not delivered to the intended network-based resources.

Abstract: In response to receiving a reservation request at a provider network, metadata indicating that a group of network addresses of a subnet is reserved for operations of a particular category is stored. A first request for an operation, requiring assignment of an address of the reserved group is rejected if the operation does not belong to the particular category, even if the address is not in use. In response to a second request for an operation which does belong to the particular category, an address of the reserved group is assigned.

Abstract: Approaches are disclosed for providing path diversity in a data transmission network. A primary transmission path can be selected through a network, such as a backbone network, based on factors such as cost of transmission. At least one waypoint can be selected that is to be included in a secondary transmission path. The waypoint(s) can be selected such that the secondary transmission path will have few, if any, network components in common with the primary transmission path, providing significant path diversity. The waypoint(s) can be selected based on a cost ratio or other such factor. In the event of a failure of transmission of a data packet over one of the transmission paths, a second transmission attempt can be performed using the same path or the other transmission path, or both.

Abstract: A system comprising one or more computing devices implements a vehicle information extraction service. The vehicle information extraction service enables customers to provide access to proprietary encoding protocols used by the customers to communicate over a bus of a vehicle, wherein the proprietary protocols are used by the vehicle information extraction service to perform vehicle information monitoring, while at the same time protecting the confidentiality of the proprietary protocols from being accessed by third parties. Also, the vehicle information extraction service enables streaming of relevant vehicle information corresponding to customer defined event criteria without requiring non-relevant vehicle information to be streamed, which would consume considerable network resources.
