20130124972 | Electronic Content Management and Delivery Platform - An education digital reading platform provides aggregation, management, and distribution of digital education content and services. The platform ingests content from a variety of content sources, transforms the content for web-based publication, and distributes the content to connected end-user devices via a network. The transformed content preserves the original page structure of the content document regardless of the original format of the content file. As the user experiences the content, the user's web browser regularly communicates with the platform for updating reading content and connected services. User-generated content such as notes are uploaded to the platform so that the user's user-generated content can be accessed from any of the user's registered devices. Moreover, the platform enables the user-generated content and other user activities to be optionally shared among friends, classmates, campus, or other groups, as part of an education social platform. | 05-16-2013 |
20130151300 | Time Based Data Visualization - An education digital reading platform collects time based user activity data and time based instruction data to generate time based views displaying a user's progress.

Time based instruction data includes a syllabus, due dates, and deadlines associated with a user's class. An interface system aggregates the user activity data from one or more users along with the instruction data to generate views of a user's progress. The views may be displayed, for example, as a timeline or a calendar. The views may enable a comparison between the activities of multiple users or a comparison of one or more user's activities to a syllabus. | 06-13-2013 |
20130171609 | Connecting Users in an Education Platform - An education digital reading platform suggests connections between users, wherein the users are represented as nodes in a social graph.

In addition, the method comprises coalescing text into paragraphs and creating a structured document page in a markup language format using the extracted images, text and fonts rendered with layout fidelity to the original ingested document page. | 07-04-2013 |
20130174272 | Digital Content Distribution and Protection - Embodiments provide a system for content distribution and protection. The system first receives an order from a user for a protected document. In response to a successful user authentication, the system generates an access code for the user to access the protected document. In response to a received user reading request, the system validates the access code for a reading session. The system then transfers a set of URLs for accessing a set of pages and associated metadata in the protected document to the user. The set of URLs are valid for a period of time. Responsive to a request for reading a next set of pages, the system again validates the access code for the session and transfers another set of URLs for accessing the next set of pages. The system also logs user activities related to the protected document. | 07-04-2013 |
20140012685 | Characterization of Layered Documents in HTML5 Publishing - An education digital reading platform provides pages of a document requested by a user, the pages including additional content layers associated with the requested content. The additional content layers including related content, user generated content, advertisement content and other services content offered by the digital reading platform. The requested content and additional content layers require processing capability on a web browser application. The amount of data associated with a page of a document may vary dramatically especially considering the additional layers of content associated with the pages. In order to permit the web browser application anticipate the processing needs associated with each page, the digital reading platform provides markers indicating a difference in processing requirements associated between two pages of a document. The markers enable the web browser request additional resources to provide a seamless user experience or enable the web browser application to request additional or fewer content layers. | 01-09-2014 |
