A response evaluation module for teaching driver training. The module teaching and evaluating student response during various simulated driving conditions. The module designed to help the driver develop good defensive driving habits.
The invention provides real time simulation techniques based on the use of holographic data storage. It possesses all of the advantages of a three-dimensional model optical pickup simulator and almost none of the disadvantages. The use of holograms eliminate the need for large models and associated structures. Coherent light and a plurality of channels, each channel controllable, and each channel adapted to receive separate holograms arranged in appropriate sequence to give simulation of motion ...
Over wide altitude ranges, signals representative of the altitude of an eyepoint viewing a synthetic grid pattern on a ground reference plane are scaled to provide strong signals. These strong signals are used to electronically define the intersection of a line of sight from the eyepoint to the grid pattern so that a clearly defined grid pattern as viewed over the wide altitude range can be displayed.
Apparatus for generating a realistic wide-screen visual display for an aircraft simulator with realistic perspective throughout plural widely different phases of simulated flight by scanning a plurality of different successive types of transparencies with a flying spot scanner to derive video signals to drive television display projectors, including the scanning of a pair of transparencies to provide a background terrain elevation image without topographical features, scanning of a second type o...
A holographic image-reproduction apparatus comprising coextensive two-dimensional arrays of developed holograms and coherent light sources operable by a keyboard and logic unit to permit selective energization of sources. Each hologram contains at least one interference pattern representing an object image at a spatial location identified by coordinate selection switches in the keyboard. A nonflat diffuser is disposed between the holograms and the viewing area to permit 360.degree. viewing.
The disclosure describes an arrangement to measure precisely probe-to-model board distance in a simulator. A source of radiation is positioned to emit a beam toward a model board surface on which a scaled terrain model is constructed. A fixed position lens collects reflected radiation and directs it onto a sensor device which develops an electrical signal indicative of displacement of the reflected beam, which, in turn, varies directly as the distance between the probe and the model board surfac...
An improvement to a periscope view simulator training device for training riscope operators. Comprises means for simulating the changing view obtained through a periscope when the periscope head is ascending from the darker ocean depths through lighter greenish colored waters near the surface and on to the daylight brightness of an above the surface position. Also simulates the view obtained when the periscope head descends from an above the ocean surface position down through the near-surface w...
A terrain model suitable for use with a viewing device to simulate terrain features of the real world with means for varying in a controlled manner the elevation of various portions of the model, thereby allowing the contour of the terrain to be changed quickly and easily. The changes are accomplished by movable actuators located beneath a deformable, elastic sheet. Means are also provided for maintaining permanent features, such as buildings, in the proper vertical relationship as the slope of ...
The display system of the present invention produces simplified environment patterns and these simplified patterns are projected on a screen which is assumed to be located a certain distance to the front of the moving body by converting the x-y coordinate of the projected patterns to voltage values, applying these voltage values to an analog electronic circuit constructed in accordance with the equations of the patterns, converting the output electric signals of the analog electronic circuit to ...
A panoramic motion picture projector useful in flight simulators and in the entertainment field is shown. A curved cylindrical segment of film which typically subtends 180.degree. at the film gate contains a full 360.degree. of picture information thus enabling projection of a complete panoramic image. The film segment is scanned by a slit of light revolving about the axis of curvature of the segment and the resulting image is converted to a rotating radial pattern having said axis as its center...
