Abstract: A transmission device and method for repeatedly transmitting punctured data messages is disclosed. The transmission device is configured to puncture an encoded data message over a plurality of consecutive time slots to provide punctured data messages. The punctured data messages include a first punctured data message and a second punctured data message that are alternately transmitted during the consecutive time slots, the first punctured data message arising from puncturing the encoded data message with a first puncture indices series and the second punctured data message arising from the puncturing of the encoded data message with a second puncture indices series that is complementary to the first puncture indices series. A reception device and method for reassembling the encoded data message based on the punctured data messages is also disclosed.

Abstract: Advances in computing and communication performance are commonly followed by applications that utilize such advances. Electronic conferences comprising audio and video may tax even the most advanced network and computing platforms when sufficient demand is placed on the conference. Accordingly, utilizing conference resources effectively and efficiently remains a concern. By allocating participating devices to either a push-to-talk group or a non-push to talk group, conference participants may selectively be enabled to contribute freely or limited to observe the conference. As a result, resources required to receive conference content from the participating devices may be allocated only to those that warrant such an allocation and not waste allocated resources that are not, or not currently, contributing to the conference content.

Abstract: A method for communication includes running a navigation application on a mobile navigation device, so as to present to a user navigation instructions from a navigation server on the display of the mobile navigation device. A widget chosen by the user is activated to run on the mobile navigation device in conjunction with the navigation application. Responsively to activating the widget, an interactive user interface element is overlaid on the navigation instructions on the display, indicating an availability of a location-based service at a location specified by the navigation instructions. Upon receiving an input from the user via the interactive user interface element invoking the service, the service is provided to the user at the specified location via the mobile navigation device.

Abstract: A method for navigation includes storing map data on a server, the map data including vector information delineating roads in a map. A portion of the vector information corresponding to an area in which a user of a mobile client device is traveling is downloaded from the server to the client device. Approximate position coordinates of the user are found using a location providing device associated with the client device and are corrected in the client device, using the downloaded vector information, so as to determine a location of the user on one of the roads in the map. A navigation aid is provided to the user of the client device based on the determined location.

Abstract: A method for displaying a map includes storing map data on a server including a plurality of layers, which include vector information delineating features in the map belonging to a respective feature category, and a set of templates, each such template being associated with a respective one of the layers and indicating a visual characteristic of the features in the layer with which the template is associated. At least a subset of the templates is downloaded to a client device from the server, as is the vector information in a portion of one or more of the layers of the map data corresponding to a selected area of the map. Based on the downloaded vector information, an image of the selected area of the map is rendered on the client device in accordance with the visual characteristic indicated by the downloaded templates.

Abstract: A method for displaying a map on a mobile client device includes storing map data on a server, the map data defining objects appearing in the map and comprising vector coordinates of the objects in a predetermined frame of reference. Upon receiving at the server a request from the client device to provide a map of an area along a route on which a user of the client device is to travel, a heading of travel of the user on the route is determined, and the vector coordinates are transformed on the server into a rotated frame of reference, which is approximately aligned with the heading of the user. A portion of the map data corresponding to the area along the route and including the transformed vector coordinates is downloaded to the client device from the server. An image of the area of the map in the rotated frame of reference is rendered on the client device, based on the downloaded map data.
