Abstract: Systems, devices, and methods are described herein for improving inventory management. As used herein, “inventory” refers to digital space at an inventory providers webpage at which content can be delivered. The disclosed techniques utilize reinforced machine learning and an offline training process to train various models with which a content request corresponding to the inventory can be classified according to historical requests and a selection process identified for the request (e.g., a direct or an indirect selection process). If an indirect selection process is chosen, the content request may be optimized for that process utilizing additional machine learning models trained using reinforced machine learning and the offline training process. The disclosed techniques enable the inventory provider to optimize content selections according to a preferred objective. The training operations are performed offline, in a training system configured to simulate the run time environment.

Abstract: Systems and methods are provided herein for natively interpreting logic across disparate platforms. Rather than executing server calls that are computationally expensive, logic may be extracted into code segments that can be evaluated at run time by an interpreter. The interpreter is passed a set of evaluators, features, and contextual data, each of which is expressed in a domain specific language. An evaluator maps an identifier to a rule and describes one or more contextual data fields with which the rule is to be evaluated. A feature corresponds to a logical condition that identifies the evaluator and a return value that is returned if the condition is met. The interpreter identifies the evaluator from the feature being evaluated and evaluates its corresponding rule based on the contextual data provided to return a return value. One or more operations may be performed based on the return value provided.

The second portion of the fitting is positioned within the interior cavity and is coupled to the first portion of the fitting to secure the first portion of the fitting to the suction cup. The filter is positioned within the chamber such that the suction cup and the fitting define a passage from the second opening, through the interior cavity, and through the chamber and the filter.

Abstract: Techniques are described herein for presenting attribute variations (differing attribute values) of an item at a network page. A request for the network page associated with an item of an electronic catalog can be received. In response to the request, the network page can be presented. The content and/or format of the network page can be predefined by an interface specification associated with the item and/or item category for the item. The network page may include a first area that includes an expanded view in which one or more variations of the first attribute are depicted and any suitable number of collapsed views in which one or more variations associated with a respective attribute are hidden from view. The areas of the network page may be dynamically expanded and collapsed to enable selection of various attribute values which may then be used to update the network page.

Abstract: A specimen tube comprises a tubular body having a first end that is open, a second end that is closed and at least one side extending axially between the first end and the second end. The side and the closed end define an interior of the tube. In sonic implementations, the specimen tube comprises a plurality of foot members protruding from the second end of the tube, wherein at least a first foot member and a second foot member have different shapes from each other. In some implementations, at least one internal wall positioned within the interior of the tube defines a sample carrier holding space between at least one surface of the internal wall and an adjacent surface of the side of the tube, the sample carrier holding space being sized to store a swab inserted from the open end of the tube.

Abstract: Image data from an image sensor is input into a predictive model to identify perimeter edges of a set of cuboidal items held on a pallet. Depth data from a depth sensor is used to identify a top surface of a first cuboidal item of the set of cuboidal items. Coordinates associated with corners of the first cuboidal item are identified using information about the perimeter edges and the top surface. The coordinates are used to generate instructions for a robotic manipulator to pick up the first cuboidal item.

Abstract: Techniques for on-demand issuance of private keys for encrypted video transmission are described. A video processing service of a provider network receives a request from a computing device outside the provider network to begin video processing of video data generated by a video source device outside the provider network. The video processing service sends instructions to a video encoding device associated with the video source device to establish the connection for video transmission. The video processing service sends an encryption key to the video encoding device, and sends a decryption key to a video decryption engine. Subsequently, the video processing service receives video data from the video source device, via the video encoding device.

Abstract: Systems and methods for providing supplemental information with a response to a command are provided herein. In some embodiments, audio data representing a spoken command may be received by a cloud-based information system. A response to the command may be retrieved from a category related to the context of the command. A supplemental information database may also be provided that is pre-populated with supplemental information related to an individual having a registered account on the cloud-based information system. In response to retrieving the response to the command, supplemental information may be selected from the supplemental information database to be appended to the response to the command. A message may then be generated including the response and the supplemental information appended thereto, which in turn may be converted into audio data representing the message, which may be sent to a voice-controlled electronic device of the individual.

Abstract: A satellite provides communication between user terminals (UTs) and ground stations that connect to other networks, such as the Internet. To establish initial contact with a satellite, a UT searches for a satellite's beacon using a phased array or other steerable antenna with a directional receive pattern. The UT retrieves a sky coverage map and stored satellite ephemeris data. The sky coverage map defines discrete areas of the entire sky, with each area based on satellite beacon coverage areas, receive beamwidth of the UT receive antenna, and receive antenna horizon limits. Based on a geolocation of the UT, time, and the ephemeris data, a predicted area in the sky of the satellite is determined. Candidate areas of the sky coverage map are determined that overlap the predicted area, and the receive antenna is directed to search the candidate areas for the satellite beacon.

Abstract: This disclosure is directed to, in part, a processing pipeline for detecting predefined activity using image data, identifying an item-of-interest and a location of the item-of-interest across frames of the image data, determining a trajectory of the item-of-interest, and determining an identifier of the item-of-interest and an action taken with respect to the item-of-interest. The processing pipeline may utilize one or more trained classifiers and, in some instances, additional data to identify items that are placed into or removed from a tote (e.g., basket, cart, or other receptacle) by users in material handling facilities as the users move around the material handling facilities.

Abstract: A request to modify a set of permissions (e.g., delete the permissions, replace the set of permissions with a different set of permissions) is received at a computing device. A set of services are prevented from using the set of permissions to access resources. The set of permissions are changed while the set of services are prevented from using the set of permissions to access resources.

The spatial database determines one or more elements of spatial data matching the query from the plurality of elements of spatial data that were stored using the plurality of storage resources.

Abstract: A system that implements a scalable data storage service may maintain tables in a data store on behalf of storage service clients. The service may maintain table data in multiple replicas of partitions that are stored on respective computing nodes in the system. In response to detecting an anomaly in the system, detecting a change in data volume on a partition or service request traffic directed to a partition, or receiving a service request from a client to split a partition, the data storage service may create additional copies of a partition replica using a physical copy mechanism. The data storage service may issue a split command defined in an API for the data store to divide the original and additional replicas into multiple replica groups, and to configure each replica group to maintain a respective portion of the table data that was stored in the partition before the split.

Abstract: A distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer (LB) nodes according to a per-flow hashed multipath routing technique. For a given packet flow, the LB nodes randomly select a server node as a target for the packet flow from among multiple server nodes and send a connection request to the server node. A load balancer module on the server node makes the decision on whether to accept or reject the connection based on one or more metrics indicating a respective server's current load. If the module accepts the connection request, a connection is established between the server and the client. Otherwise, the load balancer nodes may select another server node and try again. The connections established between clients and servers pass through the load balancer nodes, but are not terminated at the load balancer nodes.

Abstract: Virtual resources may be provisioned in a manner that is aware of, and respects, underlying implementation resource boundaries. A customer of the virtual resource provider may specify that particular virtual resources are to be implemented with implementation resources that are dedicated to the customer. Dedicating an implementation resource to a particular customer of a virtual resource provider may establish one or more information barriers between the particular customer and other customers of the virtual resource provider. Implementation resources may require transition procedures, including custom transition procedures, to enter and exit dedicated implementation resource pools. Costs corresponding to active and inactive implementation resources in a dedicated pools associated with a particular customer may be accounted for, and presented to, the customer in a variety of ways including explicit, adjusted per customer and adjusted per type of virtual resource and/or implementation resource.
