Abstract: A method and a mobile device comprising an address linking module assess a segment of text as comprising an address and create a link. The method comprises: searching a text for a segment of text having at least two character strings satisfying a proximity constraint, each character string being of a different predefined address indicator type; assessing whether or not the segment comprises an address; displaying at least a portion of the text comprising the segment on a display of a mobile device; and if the segment is assessed as comprising an address, including a link for display, the link pointing to at least one application.

Abstract: A method of reducing waypoints representing a path defined along a route between two endpoints. The route includes a set of critical points including the endpoints and any decision points of the route intermediate the two endpoints. One or more waypoints of the path that are distal each critical point are eliminated, while retaining waypoints that are proximal each critical point. This enables the computation of a reduced waypoint path which provides accurate route-following in the vicinity of each critical point of the route.

Abstract: A handheld electronic device, such as a GPS-enabled wireless communications device with an embedded camera, a GPS-enabled camera-phone or a GPS-enabled digital camera, determines whether ephemeris data needs to be obtained for geotagging digital photos taken with the device. By monitoring user activity with respect to the camera, such as activation of the camera, the device can begin pre-acquisition of a GPS position fix by obtaining needed ephemeris data before the photograph is actually taken. This GPS pre-acquisition improves the likelihood that a position fix (GPS lock) is achieved by the time the photo is taken (to enable immediate geotagging). Alternatively, the photo can be geotagged retroactively by appending the current location to the metadata tag associated with the digital photo. An optional acquisition status indicator can be displayed on a user interface of the device to indicate that a position fix is being obtained.
