Patent number: 8736564Abstract: Methods and apparatus are provided related to proximity detection between a mobile device and a related object, such as a holder, holster, pocket liner, support surface, or the like. A pattern is associated with the related object or device, for example printed on a surface thereof, the pattern being discernable by a mobile device input module, such as a touch surface or optical navigation module. When the pattern is presented to the input module, the mobile device detects the pattern and may respond accordingly, for example by shifting to a standby mode or suppressing mobile device inputs.Type: GrantFiled: May 25, 2011Date of Patent: May 27, 2014Assignee: BlackBerry LimitedInventors: Kuo-Feng Tong, Devin Jay Kaiser

Publication number: 20130092838Abstract: An optical navigation device, such as an optical navigation joystick or mouse, includes an internal redirector which may be separate or formed from material of a touch surface of the optical device. The redirector is disposed at an angle with respect to a plane of the touch surface, operative to reflect light which would otherwise strike the touch surface at a low angle and be internally reflected. The light may be reflected in a direction away from a light sensor of the device, reducing sensed internally reflected light, or may be reflected into the touch surface at a higher angle, potentially increasing a quantity of good signal. The redirector may also include portions which block light directly emitted from a light emitter, or reflected off other surfaces of the navigation device.Type: ApplicationFiled: October 14, 2011Publication date: April 18, 2013Applicant: RESEARCH IN MOTION LIMITEDInventors: Arnett Ryan WEBER, James Alexander ROBINSON, Robert James LOWLES, Derek Raymond SOLVEN, Kuo-Feng TONG, Yun Seok CHOI

Patent number: 8390569Abstract: An optical trackpad module is described herein. The module includes a light source and a trackpad that is optically coupled to the light source such that light from the light source can reach the trackpad. The trackpad is configured to receive an input object. The module also includes a sensor array that receives at least some of the light from the light source that is reflected off the input object. The sensor array is divided into sub-sections, and each sub-section corresponds to a portion of the trackpad. In addition, each sub-section detects at least translational movement of the input object on the corresponding trackpad portions to enable detection of rotational motion of the input object on the trackpad.Type: GrantFiled: November 25, 2009Date of Patent: March 5, 2013Assignee: Research In Motion LimitedInventors: Fredrik Martin Stenmark, Kuo-Feng Tong
