Patent number: 11126688Abstract: As a web browser application executing on a computing renders a web application that contains a plurality of objects, the web browser application carries out, respectively for each object, a set of resource-consumption actions involving use of resources of the client device. Further, the web browser application dynamically manages operational states of the objects based on a cumulative resource-consumption of the web application, including (i) determining that the cumulative resource-consumption of the web application exceeds a defined limit, and (ii) responsive to the determining, transitioning at least one of the objects from a first operational state to a second operational state, where the object contributes less to the cumulative resource-consumption of the web application in the second operational state than in the first operational state.Type: GrantFiled: July 7, 2020Date of Patent: September 21, 2021Assignee: ServiceNow, Inc.Inventors: Christopher Tucker, Qian Zhang, Yaron Guez, Sha He

Publication number: 20190051215Abstract: Techniques for providing medical image processing training are described herein. According to one embodiment, at least one medical image associated with a medical image processing training course (MIPTC) is displayed in a first display area. An instruction is displayed in a second display area, where the instruction requests a user to perform a quantitative determination on at least a portion of a body part within the medical image displayed in the first display area. In response to a user action from the user, the requested determination is performed on the displayed medical image. It is determined automatically without user intervention at least one quantitative value representing a result of the user action. The quantitative value is compared to a predefined model answer.Type: ApplicationFiled: October 13, 2018Publication date: February 14, 2019Inventors: Gelson Campanatti, JR., Vishal Chodnekar, Sha He, Robert James Taylor
