Abstract: An aerodynamic spare tire cover system is provided for use with a spare tire stored on a vehicle underbody. The cover system can be used to cover a full sized spare tire or a temporary spare tire, while providing the same aerodynamic qualities. The cover system includes an annular spare tire cover defining a central aperture, a removable center cap for selectively covering the central aperture, a center spacer supported by the annular spare tire cover that is adjustable between a first position and a second position depending on whether a full sized spare or temporary spare is being covered, and removable spacers supported by the annular spare tire cover. A full sized spare tire and the center spacer in the first position space the spare tire cover the same distance from a position on the vehicle underbody, on the opposite side of the spare tire, as a temporary spare tire, and the center spacer in the second position.

Abstract: A system in accordance with the invention includes an interactive video system that creates immersive multimedia experiences through responsive physical interaction and audience participation. The system transform floors, walls, screens, staging and other surfaces and video output devices into an interactive experience. Motion tracking and projection systems enable the combination of a background message to be manipulated in response to audience participation, including human body movements. Included within the system is a software application with a setup and programming user interface, used in conjunction with external hardware to which it is connected. External hardware includes, in one basic embodiment, one or more video projectors, one or more video cameras, and one or more computers. The computer receives input from the video cameras, and modifies the projected video based upon that input. A single system unit can be networked to other system units on a LAN, WAN, or global network.
