Abstract: The disclosure extends to methods, systems, and computer program products for detecting whether an illumination source of an endoscope is in use (inside the body of a patient) versus not in use (outside the body of a patient). The disclosure relies on the fact that the working environment is lit solely by the endoscope and its components. Thus, communication between the illumination or light source controller and the imaging device, such as a surgical camera, is required. When the illumination or light source is turned off and the endoscope is outside the body, a sensor will detect ambient light alerting the illumination source controller that it is outside the body, which then keeps the illumination source off or at a low intensity level. Conversely, when the illumination source is turned off and the endoscope is inside the body, the sensor will not detect any light (or will detect only a very low level of light).

Abstract: The present disclosure extends to methods, systems, and computer program products for producing an image in light deficient environments and associated structures, methods and features is disclosed and described. The features of the system may include controlling a light source through duration, intensity or both; pulsing a component controlled light source during the blanking period; maximizing the blanking period to allow optimum light; and maintaining color balance.

Abstract: An electronic publishing platform maps supplemental content layers associated with one or more paired target documents, such as user-generated content layers associated with the paired target documents, into a source document. The publishing platform correlates content items in the source document to content items in the paired target documents. Based on the correlation, the publishing platform generates indexes mapping the source document content items to the paired target document content items. The publishing platform uses the indexes to map supplemental content layers associated with the paired target document to the source document.

Abstract: A method, a storage medium and a system for document content reconstruction are provided in a digital content delivery and online education services platform to enable delivery of textbooks and other copyrighted material to multi-platform web browser applications. The method comprises ingesting a document page in an unstructured document format. The method further comprises extracting one or more images and metadata associated with the images and text and fonts associated with the texts from the document page. 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.

Abstract: 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.

Abstract: A system for hosting one or more online feedback forums to receive and manage feedback is provided. An online feedback forum can be affiliated with a provider of a service and/or product and enables users of the service and/or product to add postings to provide feedback, browse postings, and add comments to postings. Also, an online feedback forum can allow users to vote on various postings. When a new posting is added by a user, contextual information associated with the user's activity with a provider's service and/or product is also included. Contextual information includes information that is not directly inputted by the user but provides additional information for placing the user's posting in better context. The online feedback forum further enables the affiliated provider and/or its agents to add official responses to postings and otherwise manage postings of the online feedback forum.
