Abstract: A system for communicating between a first network and a second network, wherein the first network may alternately communicate through one of a plurality of communication devices, each having a different IP address. In one embodiment, the first network is contained in a vehicle. The first network initiates communications through one of the communication devices and communicates the IP address of this currently-used device to a proxy server. If communications are lost, the first network attempts to establish communications through another of the communication devices. In a first mode, the first network communicates with the second network directly, using the IP address of the currently-used communication device for return communications. In a second mode, the first network communicates with the second network directly, but return communications are routed through the proxy server, which forwards them to the first network.

Abstract: A method and system is disclosed for detaching Java applets from the constraints of the application such as a browser which provides the Java engine for executing those applets. Thus, the applets, when detached, can appear in a detached window which is more easily controllable by the operating environment desktop. The Java applets continue to run under the application's virtual machine but do so without regard to the graphical interface limits of the application. Further, if the application that launched the applet proceeds to a new URL location, the Java applet continues to run. Also, the applet, once detached, can be reattached into the application to appear in the application history.

Abstract: A dashboard for a vehicle, comprising a monitor which displays graphical images depicting dashboard instruments. In one embodiment, the monitor is a general purpose LCD graphics display coupled to a graphics generator. The graphics generator is a processor which executes a virtual dashboard software application. The processor receives vehicle information such as speed, fuel level, mileage and battery charge, and processes this information using the virtual dashboard software application to generate graphics signals which are transmitted to the monitor for display to the driver. The images displayed to the driver are determined by the virtual dashboard application, and not by the monitor itself. The displayed images are user-selectable so that they can be varied to suit the preferences of different drivers. The driver may alternately select different groups of images to view on the monitor using touch screens or speech commands.
