Publication number: 20160321644Abstract: A first device acquires target object information and generates a graphic code according to the target object information and corresponding first user account information. The first device displays the graphical code on the screen so that a second device scans the graphic code and uploads the graphic code to a remote server, which extracts the target object information and the first user account information from the graphical code, carries out a commercial transfer operation on the target object information while returning numerical commercial value transfer progress information to the first device during the process of the operation. The first device then displays the progress information on the screen. Sometimes, users of the first device and the second device exchanges respective user account information of a social network application via the remote server with each other so that the two enter a chat session with each other from the respective devices.Type: ApplicationFiled: June 21, 2016Publication date: November 3, 2016Inventors: Kai ZENG, Yu LI

Patent number: 9020230Abstract: A method for reconstructing an image of an object that includes a plurality of image elements. The method includes accessing image data associated with a plurality of image elements, and reconstructing an image of the object by optimizing an objective function, where the objective function is optimized by iteratively solving a nested sequence of approximate optimization problems. The algorithm is composed of nested iterative loops, in which an inner loop iteratively optimizes an objective function approximating the outer loop objective function, and an outer loop that utilizes the solution of the inner loop to optimize the original objective function.Type: GrantFiled: November 2, 2011Date of Patent: April 28, 2015Assignees: General Electric Company, The University of Notre Dame Du Lac, Purdue Research FoundationInventors: Zhou Yu, Evgeny Drapkin, Bruno Kristiaan Bernard De Man, Jean-Baptiste Thibault, Kai Zeng, Jiang Hsieh, Brian Edward Nett, Debashish Pal, Lin Fu, Guangzhi Cao, Charles A.

Patent number: 8965398Abstract: Examples disclosed herein relate to utilizing Bluetooth beacons for location determination of a mobile device. A Wi-Fi signal scan and a Bluetooth beacon scan are initiated at the mobile device. A location of the mobile device is determined based on at least on at least one Bluetooth beacon detectable by the mobile device, where the at least one Bluetooth beacon is transmitted from a first location, and where the first location is the location of the mobile device. A user of the mobile device is prompted for location information input, in response to determining that no Bluetooth beacons are detectable by the mobile device or when the at least one Bluetooth beacon detected is determined to be transmitted from a second location different from the location of the mobile device.Type: GrantFiled: September 26, 2012Date of Patent: February 24, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jindan Zhu, Kai Zeng, Prasant Mohapatra, Kyu Han Kim
