Abstract: Method and apparatus for previewing new events in a computing device having a plurality of applications for managing respective events are described. Individual applications are each represented by an application icon on a screen of a graphical user interface for the device. In response to a new event of a one of the applications, the application's icon is visually modified to notify of the new event. A visual modification may be determined in response to the new event, for example, to preview a content of the event. The visual modification may include a count of all new events that remain to be disposed. On a selection of the visually modified icon, additional previewing may be provided. Activation of the application having a visually modified application icon may be configured to automatically initiate the application at the new event.

Abstract: A method of establishing a secure communication channel between a first communication device and a second communication device. The secure communication channel is defined by one or more algorithm options and the one or more algorithm options are associated with one of one or more option categories. The method includes receiving a signal representing one or more selections. The method further includes, for the respective option categories, generating a sorted list of algorithm options based on the received selections and generating a security association proposal including one or more of the algorithm options from the respective sorted lists of algorithm options. The security association proposal is generated based on an order in the sorted list of algorithm options. The method further includes transmitting the security association proposal to the second communication device for establishing the secure communication channel.

Abstract: A method at a sensor apparatus affixed to a transportation asset. The method includes calibrating the sensor apparatus by initiating a vertical impact at the transportation asset, measuring spring oscillation and creating a model of the transportation asset. The method further includes detecting, subsequent to the calibrating, an impact event at the sensor apparatus. The method further includes measuring spring oscillation due to the impact event at the sensor apparatus and using the measured spring oscillation in the model created during calibration to create a load mass estimate for the transportation asset.
Abstract: A method of generating a display object is provided, the method comprising operating a first processor comprised within a first device to: execute an application; generate an display object associated with the application; output the active display object on the first device; transmit the display object to a second device for output by the second device; and receive user input to the application via the display object output on the second device.

Abstract: A method for key agreement between a first party and a second party over a public communications channel, the method including selecting, by the first party, from a semigroup, a first value “a”; multiplying the first value “a” by a second value “b” to create a third value “d”, the second value “b” being selected from the semigroup; sending the third value “d” to the second party; receiving, from the second party, a fourth value “e”, the fourth value comprising the second value “b” multiplied by a fifth value “c” selected by the second party from the semigroup; and creating a shared secret by multiplying the first value “a” with the fourth value “e”, wherein the shared secret matches the third value “d” multiplied by the fifth value “c”.
Abstract: The present disclosure relates to a method and system for managing a meeting session.

Abstract: Uplink control channel resource allocation for an enhanced downlink control channel is disclosed. A first example method disclosed herein includes receiving, at a user equipment (UE), a downlink control channel carrying a physical uplink control channel (PUCCH) resource indicator, mapping the PUCCH resource indicator to a first offset, mapping a position of the downlink control channel to a second offset, and mapping a linear combination of the first and second offsets to an index identifying a first PUCCH resource. A second example method disclosed herein includes, in response to receiving, at a UE, an indication of a dynamic resource offset in an enhanced physical downlink control channel (ePDCCH) transmitted in a first ePDCCH set, determining a position of the ePDCCH and a subframe offset, and processing the indication of the dynamic resource offset, the position and the subframe offset to determine an allocated uplink control channel resource for the UE.

Abstract: In some implementations, a method of wireless communications between a wireless communications network and wireless user equipment includes receiving, using a primary Time Division Duplex (TDD) configuration, data on a primary component carrier in a first frequency band. Using a secondary TDD configuration, data on a secondary component carrier is received in a second frequency band different from the first frequency band. A Hybrid Automatic Repeat Request (HARQ) for data received on the secondary component carrier is transmitted using a supplemental TDD configuration. A transmission or retransmission on the secondary component carrier uses a supplemental TDD configuration as well. The supplemental TDD configuration is different from the secondary TDD configuration. Furthermore, an uplink supplemental configuration may be different from a downlink supplemental configuration.
Abstract: A method in a first wireless communication device for displaying current location information representing a current location of a second wireless communication device. The method entails, from within a communication application executing on a processor of the first wireless communication device, receiving the current location information representing the current location of the second wireless communication device, performing a reverse look-up of the received current location of the second wireless communication device to determine address information, displaying a map from within the communication application, and identifying the received current location information on the displayed map with a name associated with the determined address information.

Abstract: Methods and devices for determining whether a mobile device has been compromised. File tree structure information for the mobile device is obtained that details at least a portion of a tree-based structure of folders and files in a portion of memory. The file tree structure information is analyzed to determine that the mobile device has been compromised, has not been compromised, or might be compromised. Based on determining that the mobile device might be compromised, the mobile device is instructed to execute a restricted action. If the restricted action occurs on the mobile device then it is determined that the mobile device has been compromised. Based on that determination, an action is taken.
