Abstract: A room for use in conducting medical procedures includes an image on a screen disposed in the room. The room preferably includes a track for disposing the screen across the room to create a panoramic view of the scene in the screen. Preferably the track, and hence the image on the screen disposed on the track, are arcuate. The screen provides a virtual reality and a calming effect to the patient undergoing the procedure. The screen can be moved mechanically around the room to display different images on the screen. The screen can be changed to provide a different set of images. Ceiling lights, sounds and smells can be added to the room to further accent the theme of the screen's image and enhance the overall calming effect by portraying the medical procedure room as the scene in the screen. Illumination may be provided behind the screen, as well. The medical procedure may be a magnetic resonance imaging procedure, in which case the room comprises a magnetic resonance imaging assembly.

Abstract: A display device comprising the following arranged from light input side in the order listed below: a first reflector having a semi-transmissive and semi-reflective property; a translucent porous body having a plurality of pores in which a translucent material is filled, each of the pores having a substantially smaller diameter than the wavelength of input light; and a second reflector having a perfect reflection property, or a semi-transmissive and semi-reflective property. The average complex refractive index of the translucent porous body is changeable with respect to each display dot, and the wavelength of light absorbed by the translucent porous body is changeable with respect to each display dot according to the average complex refractive index. In this way, the input light is modulatable, and the modulated light is outputted from the first reflector and/or the second reflector to perform image display.

Abstract: A multi-picture frame includes a picture panel having a front transparent surface, a casing having a receiving chamber mounted at a back of the picture panel, a picture film rotatably supported in the casing and adapted for being view from the front transparent surface of the picture panel, a light source disposed in the receiving chamber of the casing, a moving picture frame mounted between the picture panel and the light source, comprising a rolling device mounted in the casing and a shader slide arranged to be rotatably driven by the rolling device, and an electric input electrically connected the light source and the moving picture frame to a power source respectively. Therefore, the light source generates light which is adapted for passing through the shader slide to the picture film so as to reflect a moving image of the shader slide on the picture film.

Abstract: A system and method for displaying advertising. A movable medium moves continuously and displays an image. An object is disposed in front of the movable medium. The movement of the image displayed on the movable medium in relation with the object creates the effect that the object is moving in relation to the image.

Abstract: A sign for alternately exhibiting two different displays. The sign comprises a display face, a pair of belts which carry the display material and two rollers which are mounted to a carriage for travel back and forth across the sign face. The belts are secured at one end to opposite sides of the sign face and at the other end wind around respective rollers. In operation the belts wind onto or off their respective rollers as the carriage travels back and forth on a rail across the sign to sequentially exhibit for view or conceal the display material on each belt. The drive mechanism for the carriage comprises an endless cable or belt running between pulleys at each end of the rail and attaching to a slide mechanism on the carriage.

Abstract: The present invention relates to an illuminating device that will create a continuously moving ripple effect on the area illuminated. The device comprises a patterned endless belt transported on a pair of driven rollers. One side of the belt is illuminated preferably by a point light source. As the belt is driven, the patterns on the two sides pass each other in opposite directions. This creates a rippled light effect. The device is particularly well adapted for use with an aquarium to simulate underwater, the effect caused by ambient light shining through surface ripple and waves upon the bottom of a body of water.

Abstract: A multiplicity of optic fibers are secured at their outer ends in a spaced-apart pattern at the front surface of a viewing panel and at their inner ends in a concentrated, spaced-apart pattern at the rear, input surface of a reader panel for registry with correspondingly spaced holes arranged in an elongated tape in patterns of letters, numbers and/or other desired indicia to be displayed for viewing in greatly enlarged form. A source of light is positioned on the side of the tape opposite the inner ends of the optic fibers for illuminating those fibers which register with holes in the tape. Drive mechanism is provided for moving the tape past the inner ends of the optic fibers for producing a traveling light display.

Abstract: A highway game has a base supporting a conveyor-like roadway belt on which a toy vehicle is mounted. The vehicle has a control mechanism mounted at one end of the base and this mechanism includes a winding device wound with a tether secured to the vehicle. The roadway belt is driven in one direction by a motor to turn the wheels of the tethered vehicle and simulate movement of the vehicle in the opposite direction. The winding device of a simplified form of the game is mounted on a transverse shaft which can be rotated manually to shift the vehicle longitudinally on the rotating roadway belt. In a preferred embodiment of the game, the control mechanism is driven by a power take-off from the motor and the winding device is slidably mounted on a control shaft which is movable to engage and disengage the device from the drive so as to achieve a similar longitudinal movement of the vehicle.

Abstract: A changeable printed alphanumeric display module is disclosed for displaying one character at a time in a viewing window. Each tape of a set of tapes is printed on both front and back surfaces with character segments and is connected between a driving roller and a driven roller in a manner to display one front surface segment and one back surface segment at a time. The tape segments which carry the respective character segments are progressively longer from one end of the tape to the other and the set of tape segments which are displayed together in the window all bear different character segments of the same character so that an entire character is displayed. All tapes in the set are driven in unison to successively present the character segments of each tape in registry with respective window segments.

Abstract: A three dimensional viewing device which creates the illusion of objects moving in space by utilizing a plurality of illuminated foreground scenes having cutouts through which a moving background scene illuminated with ultraviolet light is visible to provide depth and motion. The device includes a housing, a plurality of upwardly extending side walls, a rear wall, a removable top and a front wall with a large opening therethrough for viewing the displays. The entire device forms a viewing chamber. Provision is made in the front of the chamber for a plurality of vertically oriented picture members to be secured in guide tracks along the side walls and behind the viewing opening. These picture members, having a plurality of cutouts therethrough, are illuminated by a light mounted near top of the front panel.
