  • Publication number: 20200327500
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for managing projects using references between the project and project items. Project items can be, for example, synchronized content items, collaborative content items, other projects, folders, tasks, user accounts, etc. The content management system can create a project identifier for managing data and/or people associated with a project. In various implementations, the content management system can store references between the project and project items in one or more folders associated with the project, in a database, in content item metadata, etc. In some implementations, the storage location of a content item does not affect whether it is associated with the project. When a project is selected by a user, the content management system can generate project view that presents various project items associated with the project in a convenient and easy to access graphical user interface.

  • Patent number: 10803616
    Abstract: A system generates a user hand shape model from a single depth camera. The system includes the single depth camera and a hand tracking unit. The single depth camera generates single depth image data of a user's hand. The hand tracking unit applies the single depth image data to a neural network model to generate heat maps indicating locations of hand features. The locations of hand features are used to generate a user hand shape model customized to the size and shape of the user's hand. The user hand shape model is defined by a set of principle component hand shapes defining a hand shape variation space. The limited number of principle component hand shape models reduces determination of user hand shape to a smaller number of variables, and thus provides for a fast calibration of the user hand shape model.

  • Patent number: 10803413
    Abstract: A provider network is configured to provide continuous workflow service for an open-ended number of workflows using non-persistent threads. The provider network includes a workflow translator service configured to receive workflows defined according to multiple workflow domain specific languages and translate the received workflows into a particular domain specific language used by the workflow service to execute workflows. In some cases, the provider network includes a workflow handling service and a workflow evaluation service. The workflow handling service may receive indications of task completion events related to respective workflows, and in turn may send non-blocking requests for workflow decisions from the workflow evaluation service. In generating a workflow decision, the workflow evaluation service may determine resources for executing a workflow.

  • Patent number: 10796255
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for managing project tasks using content items. A user can create tasks within a content item. The tasks can be assigned to users and/or be assigned due dates. The content item can be shared with other users such that updates to the content item (e.g., updates to the tasks) can cause sending notifications to users associated with the content item. When a task in the content item is updated, all members of the project can be notified of the updated status of the task. A task list for a project can be created that aggregates tasks from multiple content items associated with the project. Tasks can be organized in the task list according to the content item the task was created in. Updates to tasks in the task list can cause corresponding updates to the tasks in the content items.

  • Publication number: 20200313976
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a content platform that receives a request to provide a digital component. The request includes information about users to which the digital component is directed. Futurized queries are obtained from serving logs of a serving system that is configured to execute an existing digital component using serving code that directs digital content to the set of users. The futurized queries are loaded as data structures in memory of a forecasting system. The system uses an instruction set derived from the serving code to determine that similarity between the particular futurized query and the request exceeds a threshold similarity. The system then generates a forecast output as a response to the request based on futurized queries that exceed the threshold similarity. The forecast output includes data describing future provision of the digital component.
