  • Publication number: 20180332274
    Abstract: A digital cinematographic and projection process that provides 3D stereoscopic imagery that is not adversely affected by the standard frame rate of 24 frame s per second, as is the convention in the motion picture industry worldwide. A method for photographing and projecting moving images in three dimensions includes recording a moving image with a first and a second camera simultaneously and interleaving a plurality of frames recorded by the first camera with a plurality of frames recorded by the second camera. The step of interleaving includes retaining odd numbered frames recorded by the first camera and deleting the even numbered frames, retaining even numbered frames recorded by the second camera and deleting the odd numbered frames, and creating an image sequence by alternating the retained images from the first and second camera.

  • Patent number: 6454411
    Abstract: An apparatus for directly projecting an image onto a retina includes an optical source for generating a light beam to be focused on a retina. A projection device sweeps the light beam along the retina in an ellipsoidal pattern such that a higher spatial concentration of light pixels impinge a central portion of the retina than a peripheral portion thereof. A controller is coupled to the optical source and the projection device for modulating the light beam such that a higher temporal concentration of light pixels impinge a central portion of the retina than a peripheral portion thereof.

  • Patent number: 5795228
    Abstract: An interactive computer-based entertainment system interacts with a user and presents to the user an interactive show comprising audio, video images and computer-generated graphical images. The entertainment system comprises a user interface, a database, a show controller and an activity server. The user interface receives user input signals indicative of user input actions, and further presents user output signals to the user. The user output signals are indicative of the audio, video and computer graphical images generated by output devices. The database receives the user input signals and generates in dependence thereupon database signals which are indicative of an informational record of the user. The informational record is indicative of user characteristics which serve to uniquely identify the user. The show controller generates a first set of show control signals indicative of the audio, the video images and the computer-generated graphical images of the show.

  • Patent number: 5584697
    Abstract: A simulator system for use in providing an event simulation to a passenger includes an inverted motion base having six degrees of freedom. An audio-visual display mechanism is included for providing a sequence of audio and visual images to the passenger. A motion base controller generates actuator drive signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images. The motion base is characterized by an passenger platform which is suspended from a series of spars. Motion is accomplished by means of displaceable actuators arranged in a substantially orthogonal relationship. The present system has compact dimensions and minimize loads impressed to the surrounding structure; thereby allowing the present system to be incorporated into existing commercial structures with minimal modification.

  • Patent number: 5527184
    Abstract: A simulator system for use in providing an event simulation to an occupant includes a motion base moveable only along three mutually orthogonal displacement axes by means of displaceable actuators. An audio-visual display mechanism is included for providing a sequence of audio and visual images to the occupant. A motion base controller generates actuator drive signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images. The projected visual images including "foreground" and "background" portions. The system controller generates the motion base command signals such that the displacement of the motion base is synchronized to the onset of movement of the foreground image and the foreground image is constrained to move, relative to the occupant, only along the same three orthogonal axes as the motion base.

  • Patent number: 5433670
    Abstract: A compact theater for use with a simulator system includes a motion base moveable only along three mutually orthogonal displacement axes by means of displaceable actuators. A projector and screen are included for providing a sequence of audio signals and visual images to the occupants. A motion base controller generates actuator drive signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images. The system controller generates the motion base command signals such that the displacement of the motion base is synchronized to the presentation of the audio signals and visual images. The motion base is characterized by a reduced height when fully retracted such that, when configured with the projector and screen, the total height is less than conventional simulators, enabling the present theater to be housed within buildings of a standard commercial height.

  • Patent number: 5199875
    Abstract: A simulator system for use in providing an event simulation to occupants includes a motion base moveable along displacement axes by means of displaceable actuators. Feedback sensors provide signals indicative of the measured displacement of a corresponding actuator. An audio-visual display mechanism is included for providing a sequence of audio and visual images to the occupants. A motion base controller receives the feedback sensor signals and generates actuator drive signals below a cutoff frequency in response to received command signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images to the occupants. A mechanism is included for generating supplemental actuator drive signals that have frequencies above the cutoff frequency.

  • Patent number: 4889423
    Abstract: A method is described for converting a strip of film designed for showing at 60 fps (frames per second) to a film that can be shown at 24 fps. Instead of forming the 24 fps film so it alternately contains every second and every third frame of the 60 fps film, each frame of the 24 fps film includes two distinct overlapping successive images of the 60 fps film.

  • Patent number: 4874162
    Abstract: An amusement ride is provided, of the type that moves and tilts passengers viewing a motion picture, which is more versatile than prior rides. A plurality of passenger-holding frames is provided, that are all moved in sychronism, each by a separate set of actuators, while the passengers view a stationary screen. The passenger-holding frame is pivoted up and down on a beam which is supported by only two largely vertical actuators, while two pairs of links or arms limit movement of the beam.
