Abstract: Generating a dynamic legend for a drawing developed by a diagramming software program. A drawing sheet module and legend module, logically-coupled to the drawing sheet module, are useful for generating and updating a dynamic legend. The legend module can support the addition of a legend to a drawing sheet. The legend module can also determine if legend symbols should be automatically added to the legend. If legend symbols are added to a drawing sheet, that addition can be automatically reflected in the dynamic legend. Symbols can be converted such that they may be reflected in a dynamic legend.

Abstract: The size of information being display by a computer is automatically adjusted in order to make the information easily readable, while at the same time leaving most (or all) of the information displayed on a single screen. Any one or more of the font point size, the font type, the number of lines used, and the caption used can be adjusted in order to determine the manner in which the information is displayed.

Abstract: An application-to-component communication helper facilities communication between applications running an in-vehicle computer to an in-vehicle component. Each vehicle part has a corresponding object, and each object exposes a pre-defined Device Communication Application Programming Interface (DCAPI). Some objects are built-in, meaning that they are defined to some degree by the operating system, and rely on the operating system for at least parts of their functionality. Other objects are add-on objects, meaning that they are provided apart from the operating system, for subsequent installation and use in conjunction with the operating system. The operating system provides a “device helper” that allows add-on components to participate and utilize access management and notification features provided by the operating system. The device helper exposes its method for use by corresponding device-com methods of component objects.
