  • Publication number: 20050094103
    Abstract: An improved real image projection device includes a real image projection system for projecting a real image from one or more sources that transmit, reflect or emit light, operatively connected with a slot machine, gaming machine, an ATM machine, vending machine or other like machines, enhancing the functionality and experience in slot or gaming machines, ATM machines, vending machines, point of purchase merchandising displays, and the like. One embodiment includes an e-mail capture system that includes a computer, microprocessor device, memory, or other device for storing an e-mail database, and a keyboard, touch-screen device, or pointing device and display monitor, or other input device, arranged for a viewer of the real image to enter one or more e-mail addresses into the database.

  • Publication number: 20030210380
    Abstract: An improved real image projection system comprises, in the primary configuration, a tilted mirror to eliminate ghost reflections, and a unique arrangement allowing the introduction of a second background image without a 50%/50% beamsplitter, while providing system transmission of approximately 50%. A secondary configuration incorporates an elliptical or aspheric curved mirror designed to simulate the surface of a spherical curve when light strikes the elliptical surface at an angle equal to the elliptical angle of the curved mirror. In a third configuration, a single curved mirror has two different optical surfaces of revolution, one on the convex surface and one on the concave surface. The concave surface is much like that of a Mangin lens, but it has an aspheric surface of revolution, optimized to reduce spherical aberrations over a larger area offset from the optical axis.

  • Patent number: 6612701
    Abstract: A real image projection system comprising two or more optical surfaces of revolution, with at least one comprising an aspheric surface of revolution. The aspheric surface of revolution is of a design to reduce natural aberrations inherent in imaging using surface of revolutions of the conic family of curves.

  • Publication number: 20030147145
    Abstract: A real image display system includes a primary image source for projecting a primary image from the start of a primary light path to an end of the primary light path at which the primary image is viewable, two reflectors positioned in the primary light path between the primary image source and the projected real image, a circular polarizer for circularly polarizing a light beam positioned in the primary light path between the mirror and real image, whereby outside light entering the system is substantially blocked before exiting the system, thereby substantially eliminating ghost image formation caused by outside light sources.
