  • Gesture actions for interface elements
    Patent number: 9063563
    Abstract: A user interface (UI) enables a user to access a set of options relating to an element of the UI by contacting a region of a touchscreen, or hovering a feature over the region, associated with that element. Upon contacting or hovering for at least a determined period of time, an arranged set of options is displayed and the user can swipe or move the feature in a specified direction to select a specific option. The options can be the same for each instance of a type of item. When a user learns the direction of one of these options, the user does not have to contact or hover long enough to bring up the menu, but can contact or hover long enough to indicate the element of interest and then perform the appropriate motion, which can cause the action to be performed without first displaying the menu.

  • Backoff-based scheduling of storage object deletions
    Patent number: 9063946
    Abstract: Methods and apparatus for backoff-based scheduling of storage object deletions are disclosed. A storage medium stores program instructions that when executed on a processor, obtain an indication of a collection of storage objects of a network-accessible multi-tenant storage service to be deleted in accordance with specified deletion criteria. A deletion of a storage object comprises a metadata deletion operation and one or more other operations. The instructions initiate, corresponding to at least some objects of the collection, respective metadata deletion operations at a metadata node of the storage service. If a metric associated with the metadata node meets a threshold criterion, the instructions delay, by a particular amount of time, an initiation of an operation corresponding to a deletion of another storage object.

  • Dynamic tree determination for data processing
    Patent number: 9063976
    Abstract: Data can be processed in parallel across a cluster of nodes using a parallel processing framework. Using Web services calls between components allows the number of nodes to be scaled as necessary, and allows developers to build applications on the framework using a Web services interface. A job scheduler works together with a queuing service to distribute jobs to nodes as the nodes have capacity, such that jobs can be performed in parallel as quickly as the nodes are able to process the jobs. Data can be loaded efficiently across the cluster, and levels of nodes can be determined dynamically to process queries and other requests on the system.

  • Motion detection systems for electronic devices
    Patent number: 9063574
    Abstract: The amount of power and processing needed to process gesture input for a computing device can be reduced by utilizing a separate gesture sensor. The gesture sensor can have a form factor similar to that of conventional camera elements, in order to reduce costs by being able to utilize readily available low cost parts, but can have a lower resolution and adjustable virtual shutter such that fast motions can be captured and/or recognized by the device. In some devices, a subset of the pixels of the gesture sensor can be used as a motion detector, enabling the gesture sensor to run in a low power state unless there is likely gesture input to process. Further, at least some of the processing and circuitry can be included with the gesture sensor such that various functionality can be performed without accessing a central processor or system bus, thus further reducing power consumption.
