Publication number: 20150378502Abstract: A method and apparatus for managing a touch-screen device is provided herein. During operation UI elements are arranged and re-arrange dynamically and based on user's current contact locations on the touch screen. Preferably, the contact positions correspond to a user's finger positions so that the UI elements are automatically placed where a person's fingers make contact with the touch screen. Because the UI elements on the touch screen always “look for” the user's fingers, instead of the user looking for them, it becomes much easier and more time-efficient for a user to find a particular UI element.Type: ApplicationFiled: February 8, 2013Publication date: December 31, 2015Inventors: HAI-QING HU, MENG-GE DUAN, Jing WANG

Patent number: 9036674Abstract: A third-order distributed feedback laser has an active medium disposed on a substrate as a linear array of segments having a series of periodically spaced interstices therebetween and a first conductive layer disposed on a surface of the active medium on each of the segments and along a strip from each of the segments to a conductive electrical contact pad for application of current along a path including the active medium. Upon application of a current through the active medium, the active medium functions as an optical waveguide, and there is established an alternating electric field, at a THz frequency, both in the active medium and emerging from the interstices. Spacing of adjacent segments is approximately half of a wavelength of the THz frequency in free space or an odd integral multiple thereof, so that the linear array has a coherence length greater than the length of the linear array.Type: GrantFiled: March 5, 2013Date of Patent: May 19, 2015Assignees: Massachusetts Institute of Technology, LongWave Photonics LLCInventors: Qing Hu, Alan Wei Min Lee, Tsung-Yu Kao

Publication number: 20150130723Abstract: In a first step of a content selection operation, content can be selected by detecting a freeform trajectory of one or more content selection objects with respect to a computing device. The selection area can be calculated based on the maximum area covered by the trajectory of movement that is detected. The selection area can be limited to the area bounded by the start selection point and ending release point. The content within the selection area can be selected. The “roughly selected” content can be copied into a second display area. All or part of the roughly selected content can be enlarged, enabling precise selection of content in a second selection operation.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Applicant: Microsoft CorporationInventors: Jerry Huang, Zhen Liu, Chiu Chun Bobby Mak, Yang Gu, Ning Wang, Qing-Hu Li, Li Zhao
