Patent number: 8289941Abstract: A method, mobile electronic device and system for synchronizing hand-off of a voice media session between a WAN/cellular network and a WLAN network. When a hand-off occurs, the connection with both networks is temporarily maintained and the voice data on both connections compared to determine differences in the delays experienced over both connections. The timing of one or both voice streams is adjusted to synchronize the voice streams, and then the handoff is completed.Type: GrantFiled: November 3, 2010Date of Patent: October 16, 2012Assignee: Research In Motion LimitedInventor: Vytautas Robertas Kezys

Patent number: 8254283Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.Type: GrantFiled: June 7, 2011Date of Patent: August 28, 2012Assignee: Research In Motion LimitedInventors: Sherif Abdel-Kader, Michael Chen

Patent number: 8250371Abstract: A system and methods for coordinating the operation of a client security module and a host security module on a mobile electronic device. The modules communicate with each other through a platform abstraction layer using application programming interfaces to coordinate their activities. In particular, on start-up of the device, the host security module obtains user authorization input from a user and passes the input to a client operating system for validation. Once validated, the host security module unlocks the host-side of the device. At the same time, the client operating system sends a notice or request to the client-side virtual machine requesting that the client-side be unlocked. Once the virtual machine is initialized and available it launches the client security module and unlocks the client-side. During the delay while the virtual machine loads, the user is given access only to the host applications.Type: GrantFiled: July 27, 2010Date of Patent: August 21, 2012Assignee: Research In Motion LimitedInventors: Sriram Darbha, Melanie Barker, Jeffrey Kenneth Emery

Patent number: 8244310Abstract: A mobile communication device has a power amplifier and a power pack. The power pack includes a charge storage component, a first pair of taps connected to the charge storage component for supplying power to components of the mobile communication device and a second pair of taps connected to the charge storage component for supplying power to the power amplifier, the second pair of taps located, when the power is installed in the mobile communication device, more proximate to the power amplifier than the first pair of taps. With the second pair of taps positioned more proximate to the power amplifier, the power amplifier current loop that includes the multi-tap power pack may be made smaller. One benefit of a smaller power amplifier current loop may be reduced emission of RF interference signals.Type: GrantFiled: February 16, 2010Date of Patent: August 14, 2012Assignee: Research In Motion LimitedInventors: George Soliman Mankaruse, Lizhong Zhu, Michael Stephen Corrigan

Patent number: 8240560Abstract: The present disclosure relates generally to the authentication of contactless payments attempted by a device having embedded contactless payment functionality. In particular, the disclosure is directed to systems and methods that utilize authentication schemes that already exist on a device in which the contactless payment functionality is embedded. One example of such authentication schemes is the use of password protection to lock or unlock the device in which the contactless payment functionality is embedded. Using the password protection functionality may provide varying levels of authentication protection based on the desires of the user. A number of exemplary uses of such a method and apparatus are disclosed herein.Type: GrantFiled: December 22, 2009Date of Patent: August 14, 2012Assignee: Research In Motion LimitedInventors: Neil Patrick Adams, Michael Kenneth Brown, Michael S. Brown

Patent number: 8243919Abstract: When multiplicative splitting is used to hide a scalar in an Elliptic Curve scalar Multiplication ECSM operation, the associated modular division operation employs the known Almost Montgomery Inversion algorithm. By including dummy operations in some of the branches of the main iteration loop of the Almost Montgomery Inversion algorithm, all branches of the algorithm may be viewed, from the perspective of a Power Analysis-based attack, as equivalent and, accordingly, devoid of information useful in determining the value of the scalar, which may be a cryptographic private key.Type: GrantFiled: February 29, 2008Date of Patent: August 14, 2012Assignee: Research In Motion LimitedInventor: Nevine Maurice Nassif Ebeid
