Patent number: 10506077Abstract: Systems and methods are provided for image-based browsing of resources, such as webpages, on a communication device, providing for image-based navigation of recently accessed resources and image-based selection of resources matching partial or complete address strings entered in an input field. Also provided are systems and methods for predictive loading of resources, by detecting browsing actions such as zooming in and hovering over thumbnail images of previously accessed resources, and initiating HTTP requests for those resources over a network before receipt of an express command to retrieve the resource. To improve the user-perceived responsiveness of the device to commands to download and display resources such as webpages comprising embedded objects, the order of requesting updated versions of the embedded objects is determined by analysis of the portion of the webpage of interest to the user. Prioritizing of various browser-related tasks is also disclosed.Type: GrantFiled: July 30, 2014Date of Patent: December 10, 2019Assignee: BLACKBERRY LIMITEDInventor: Stefan Dimitrov

Publication number: 20180121622Abstract: Disclosed herein are embodiments of systems, methods, and products comprises an analytic server, which provides stateless decision support for clinical evaluation. The analytic server receives clinical evaluation process model from a domain expert and converts the process model into logical expressions of a decision tree. The analytic server dynamically identifies the data referenced in the process and retrieves the referenced data from external databases. The analytic server generates a stateless decision tree comprising the local expressions and the referenced data. The analytic server receives a request comprising patient data and patient needs and preferences. The analytic server determines a decision tree based on the contents of the request. The analytic server evaluates the patient against the decision tree and determines the evaluation results.Type: ApplicationFiled: October 24, 2017Publication date: May 3, 2018Inventors: Chad ARMSTRONG, Farzad KOHANTORABI, Stefan DIMITROV, Mohammadnaser ZANDI, Mostafa ERFANI, Sadiq SALEH, Travis STENERSON
