Abstract: A global positioning system (GPS) based instructional driving simulation device presents a means for a user to learn to drive an automobile in a virtual setting. The virtual setting is produced through software on a data storage device which is processed through a central processing unit (CPU) and displayed through use a graphically processing unit (GPU). The GPU outputs a video signal through a display adapter to an external monitor that is ultimately displayed to the user. The user controls the virtual automobile through a control panel. The control panel is located on a dashboard which is positioned in front of the user during use. The dashboard is part of an enclosure that houses the electronic components of the GPS based instructional driving simulation device. The presented device allows the user to learn driving standards and practices before operate a physical automobile.

Abstract: The present invention provides a dual antenna system where a first antenna element has a metallic surface with openings that are resonant at frequencies other than the operating frequency of a second antenna element. The openings are sized such that the metallic components are relatively transparent at and near resonant frequencies of those openings. According to the present invention, the resonant frequencies of the openings may be the transmitting or receiving frequencies of the second antenna element, or of nearby antennas.
