Abstract: Techniques are described for using velocity data to improve the location accuracy of Wi-Fi crowdsourcing. Instead of relying on a reported location of an electronic device that detects a communication node, such as an Access Point (AP), the location of the communication node is adjusted based on the velocity of the electronic device when the electronic device detected the communication node. When a communication node is detected, the electronic device associates the device's location coordinates and associated velocity with the detected communication nodes to create data that is tagged with the identity of the communication nodes. The communication node data is sent to a location service for processing to estimate the location of the communication nodes. The location service may adjust the location of a communication node to be a specified distance from the location of the electronic device. In some cases, the higher the velocity, the greater the specified distance.

Abstract: Methods and apparatus for a primary role reporting service for resource groups are disclosed. A reporting intermediary assigned to a resource group of a network-accessible service receives role information indicating the identity of a primary member of the group from a state manager of the network-accessible service. The intermediary receives a health status query pertaining to the resource group from a health checking subsystem used by a network address discovery service, and provides a health status response based on the role information. The response provided by the reporting intermediary is used by the network address discovery service to provide a network address in response to a lookup query for the resource group.

Abstract: In some implementations, a service provider may enable location-based interaction of a user of a device with at least one of a digital work or another user. For instance, when the service provider determines that the device of the user is at a particular physical location, the service provider may send a communication to notify the user that one or more digital works are available to be accessed at the current physical location of the device. As one example, a digital work may have been virtually left at the location by another user, and the digital work may be available to be accessed by the user currently at the location. As another example, the user may be attending an event and the service provider may offer a digital work related to the event when the user is determined to be at the location of the event.

Abstract: Aspects of the present disclosure relate to the generation and delivery of content including unique and shared components. A content delivery network service provider can obtain requests for content from client computing devices. Based on information provided in the request or otherwise managed by executable code on the client computing device, the CDN service provider obtains one or more pieces of content that may be shared by more than one user or client computing devices. Additionally, the CDN service provider obtains one or more pieces of content that will not be shared by more than one user or more than one client computing device. Responsive to the content request, the CDN service provider can combine the one or more pieces of shared content and the one or more pieces of unique content and deliver the combined content to the requested client computing device.

In some instances, the composite cover component includes a top layer and a bottom layer formed from an inorganic material and at least one inner layer formed from an organic material. In other instances, the composite cover component includes a top layer and a bottom layer formed from an organic material and at least one inner layer formed from an inorganic material.

Abstract: A user can select an object represented in video content in order to set a magnification level with respect to that object. A portion of the video frames containing a representation of the object is selected to maintain a presentation size of the representation corresponding to the magnification level. The selection provides for a “smart zoom” feature enabling an object of interest, such as a face of an actor, to be used in selecting an appropriate portion of each frame to magnify, such that the magnification results in a portion of the frame being selected that includes the one or more objects of interest to the user. Pre-generated tracking data can be provided for some objects, which can enable a user to select an object and then have predetermined portion selections and magnifications applied that can provide for a smoother user experience than for dynamically-determined data.

Abstract: Systems and methods for monitoring performance associated with fulfilling resource requests and determining optimizations for improving such performance are provided. A processing device obtains and processes performance metric information associated with processing a request corresponding to a set of resources. The processing device uses the performance metric information to identify a subset of the resources corresponding to a display location associated with a visible portion of a display and to assess performance related to processing of the identified subset of the resources. In some embodiments, the processed performance data may be used to identify timing information associated with the subset of the embedded resources.

Abstract: The initiation of a reload event by a user of a client-side application who requests a web resource from a server is an implicit indication that the user is dissatisfied with at least some aspect of the loading of the web resource by the client-side application. Information regarding the operational condition of the application at the time of a reload event may be instructive in identifying any issues or deficiencies exist regarding the web resource, the client-side application or the server. Code for displaying the web page may include one or more detection scripts which instruct the client-side application and/or the server-side application to detect a reload event, to capture the information upon the initiation of the reload event and to transfer the captured information back to the server, where the information may be compared against thresholds or tolerances to determine whether any such issues or deficiencies exist.

Abstract: Techniques are described for promoting content items in a page to load in a different order than the order in which they were initially designated to load in the page source. A page may include critical content items designated to load earlier than non-critical content items. In instances where there is a delay due to latency in generating or retrieving the critical content items, one or more non-critical content items may be promoted to be sent earlier than initially designated. Promotion may include packet reordering, such that packets including non-critical content items are sent to a user device prior to the packets that include critical content items. By promoting non-critical content items to be sent during the period in which the loading of the page may otherwise be stalled, overall page load times may be reduced.

Abstract: Image information displayed on an electronic device can be adjusted based at least in part upon a relative position of a viewer with respect to a device. In some embodiments, image stabilization can be provided such that an image remains substantially consistent from the point of view of the viewer, not the display element of the device. The image can be stretched, rotated, compressed, or otherwise manipulated based at least in part upon the relative viewing position. Similarly, the viewer can move relative to the device to obtain different views, but views that are consistent with the viewer looking at an object, for example, through a piece of glass. The device can overlay information on the image that will adjust with the adjusted image. Three-dimensional modeling and display can be used to offset parallax and focus point effects.

The backplane is positioned adjacent an end of the horizontal supporting surface and has a connector configured to establish an electrical connection between the carrierless mass storage device and the backplane. The retainer comprises a bail coupled to the supporting surface and shaped to extend around the carrierless mass storage device and to contact at least its second side surface when it is installed.

Abstract: Robotic units may operate in a workspace that is shared with human workers. In order to safeguard the workers, operation of a robotic unit may be inhibited when a worker is near the robotic unit. In order to determine the position of the worker and thereby determine the proximity of the worker and the robotic unit, a time-of-flight measurement is performed to determine the distance of the worker from each of multiple reference locations within or about the workspace. A circular bounding area is defined around each reference location based on the determined distances. A bounded position area is identified as the intersection of the circular bounding areas. The worker is then indicated as being within the bounded position area.
