Abstract: Methods and apparatus for projecting a tangible image of data characterizing an object onto a surface of the object itself. Three-dimensional measurements of the object are obtained, the measurements are processed for projection, and a tangible image is projected onto the object, the image conveying information based on the three-dimensional measurements. The image may be projected concurrently with performance of measurements. In an exemplary dental context, information derived in part from three-dimensional measurements of a tooth or replica may be projected onto the actual tooth or replica. In interactive application, a work piece is be measured during the course of fabrication, and three-dimensional information, derived from contemporaneous non-contact measurement, is projected onto the work piece in order to direct the user with the formation of the work piece.

Abstract: A lamp assembly (16) mounted to an interior frame (14) of a bowling alley score projector (10). The lamp assembly (16) includes a U-shaped bracket (34) having two end portions mounting two lamp holders (44). Lamp holders (44) have housings (46) receiving coil springs (54) which spring bias sockets (48). The sockets (48) are spring biased against terminals (60) of a dual terminal quartz-halogen light bulb (50). A center bight section (40) forming a U-shaped bracket is connected to a spacer (38) which is in turn removeably secured to an arm (32) of interior frame (14).

Abstract: A projected gaming method and apparatus including a projector, a screen, one or more three-dimensional games and display apparatus, such as a pin ball game and display, a game changer device, a game selector mechanism and player control units. Each interchangeable projectable three-dimensional game and display apparatus is connected to the projector. Each three-dimensional game and display apparatus includes a printed game control system circuit on a printed circuit board, a complete three-dimensional game mechanism and a game display means attached to the other top side of the printed circuit board, all of which are interconnected. The game mechanism and game display means are displayed on the remote screen by the projector. Each game and display is automatically moved into and out of the projector for placement on the screen by the game changer device that is activated by a player actuating the game selector mechanism.

Abstract: An improvement for use in image projection systems of the type which project an image from a substrate where a projector causes the image to be displayed on a receiving member such as a projection screen remote from the projector. One important facet of the improvement resides in the receiving member, i.e., the projection screen. These systems are typically used for displaying scores in bowling games from a projector at the player end to a screen or receiving member at the scoring end. Projectors of this type normally comprise a projector base with a mirror system and a socket which has a light source therein located in relation to the mirror system. The improvement comprises a bracket which is replaceable for the original socket and light source therein. The bracket includes a plate having an improved light socket mounted on the plate. In addition, the bracket includes mounting means having apertures to receive conventional fasteners.
