Abstract: A method for generating and using a workout file, comprising recording workout data and notes while performing an athletic workout, attaching trigger conditions to the notes, and exporting the workout data, the notes, and the attached trigger conditions as the workout file, where the exported workout file is configured to be used by a subsequent user to repeat the athletic workout in a manner that plays the notes when the subsequent user performs the trigger conditions.

Abstract: A method for increasing route accuracies, comprising receiving GPS waypoints associated position accuracy prediction (PAP) parameters, comparing the PAP parameters to corpus PAP parameters associated with corpus GPS waypoints, and updating the corpus PAP parameters and the corpus GPS waypoints based on the comparison of the PAP parameters to the corpus PAP parameters.

Abstract: A graphical user interface for use with a multi-media system, such as those found in vehicles, that includes a rotary knob, a graphics control circuit and a graphics display with a graphical depiction of a portion of the rotary knob. The graphical depiction includes a menu wheel and at least two menu items located near its periphery, where each of the menu items corresponds with a device, system or network (i.e.—satellite radio, navigation system, DVD player, video game system, wireless internet, etc.) with which the multi-media system can interact. Furthermore, rotation of the rotary knob by a user causes a corresponding graphical movement of the menu items along a periphery of the menu wheel.

Abstract: A vehicle navigation system uses a simple graphic user interface (GUI) to display a route formed by a sequence of route segments. At any given time, the vehicle navigation system displays a single route segment, defined either as the distance between consecutive turn points or as a fixed distance. The vehicle navigation system also displays a graphic representation of the vehicle. The user can scroll backward and forward through the sequence of route segments using a simple control, such as a knob or a keypad. As a result, the user can view the entire route easily without having to mentally adjust to different frames of reference, such as between an overview map and a detailed map.
