Patent number: 8014940Abstract: An electronic mobile device includes a display, a tilt sensor and a processor. The display is for displaying a graphical element. The tilt sensor is configured to measure a tilt angle of the mobile device. The processor is configured to store the measured tilt angle as a reference tilt angle, subsequently determine a delta tilt angle as the difference between a currently measured tilt angle and the reference tilt angle, compare the delta tilt angle to different thresholds, and alter the position of the displayed element on the display at a rate that is based on the number of the thresholds the delta tilt angle has exceeded.Type: GrantFiled: November 18, 2010Date of Patent: September 6, 2011Assignee: Research In Motion LimitedInventors: Kevin Howard Orr, Alexander Kornilovsky, Alexei Skarine

Publication number: 20110136485Abstract: A system and method is provided for performing a wireless reception performance test between a wireless device and a base station emulator. The method comprises generating a path loss correction factor. The path loss correction factor compensates for path loss from an antenna port of the base station emulator to an antenna port of the wireless device. The method further comprises transmitting from the base station emulator at least a further signal transmission. The further signal transmission includes the path loss correction factor such that the transmission power of the further signal transmission removes the effect of path loss from the wireless reception performance test.Type: ApplicationFiled: December 7, 2009Publication date: June 9, 2011Applicant: RESEARCH IN MOTION LIMITEDInventors: Anatoliy GORDIYENKO, Alexei SKARINE, Emil SERBAN, Xiaoqi (a.k.a.
