Patent number: 9977944Abstract: A photography subsystem is configured to be operated in fingerprint scanning mode and a normal mode. An autofocus module may be initialized to control a lens with an initial focal length set according to received instructions indicating one of the modes of operation. An image signal processor associated with the photography subsystem may process images received from the photography subsystem and, if necessary, process the images to form a candidate digital fingerprint for use in an authentication process.Type: GrantFiled: August 24, 2016Date of Patent: May 22, 2018Assignee: BlackBerry LimitedInventors: Colin Shiva Ramrattan, Robert James Lowles, Graham Charles Townsend

Patent number: 9042085Abstract: In a broad aspect, embodiments described herein are generally directed to an electronic device comprising: a housing; a component mounted within the housing; a component cover in fixed relation to the housing; wherein the component cover is configurable between at least a first state and a second state; and wherein light transmissivity through the component cover is greater when in the second state than when in the first state. In some implementations, in the first state the component cover is substantially opaque, or in the second state the component cover is substantially transparent.Type: GrantFiled: November 25, 2009Date of Patent: May 26, 2015Assignee: BLACKBERRY LIMITEDInventor: Colin Shiva Ramrattan

Patent number: 8792683Abstract: An optical navigation subsystem may be used when obtaining a candidate fingerprint for a mobile communication device (e.g., for authentication purposes). To accommodate such use of the optical navigation subsystem, the optical navigation subsystem may be adapted to automatically adjust a processed image sensor window from a first set of window dimensions (e.g., suitable for optical navigation) to a second set of window dimensions (e.g., suitable for fingerprint capture). Alternatively, a single, static set of window dimension may be employed in conjunction with stitching algorithms, or other methods suitable for forming candidate fingerprint images by combining a plurality of images obtained using the static set of window dimension.Type: GrantFiled: June 4, 2010Date of Patent: July 29, 2014Assignee: BlackBerry LimitedInventors: Colin Shiva Ramrattan, Hassan Hosseinpor, Graham Charles Townsend, Robert James Lowles, Rayhan Behin, Gregory William Jacobs

Patent number: 8730657Abstract: A mobile computing device includes a flexible display, a rigid-flex printed circuit board (PCB) arrangement, an electrically conductive memory fabric, and a controller. The rigid-flex PCB arrangement is connected to the flexible display, and has a honeycomb configuration. The electrically conductive memory fabric is connected to the flexible display and the rigid-flex PCB arrangement. The controller is configured to, by selectively controlling supply of electrical current to the electrically conductive memory fabric, control whether the electrically conductive memory fabric (i) straightens and resists flexing of the flexible display and the rigid-flex PCB arrangement or (ii) is relaxed and allows flexing of the flexible display and the rigid-flex PCB arrangement.Type: GrantFiled: June 24, 2011Date of Patent: May 20, 2014Assignee: BlackBerry LimitedInventors: Colin Shiva Ramrattan, Mohamad El-Hage
