  • Patent number: 9507151
    Abstract: A head up display or HUD system, including methods and apparatus, suitable for use in a flight simulator. According to the present teachings, a flight simulator HUD may be configured to produce a HUD image that appears superimposed on a simulated cockpit field of view image, and which has substantially the same relatively short focal distance from the user as the simulated image. A simulator HUD according to the present teachings does not require any holographic optical elements or an unrealistic cockpit volume, and provides an accurate simulation of conditions in a real aircraft cockpit.

  • Patent number: 9470967
    Abstract: The present disclosure is generally directed toward a visual image projection and display system including a motion platform, a toroidal constant vertical resolution surface having a bottom portion mounted to the motion platform and capable of displaying a single substantially constant vertical resolution image by blending portions of adjacent projected images on the toroidal constant vertical resolution surface, a top surface screen intersecting the top portion of the constant vertical resolution surface defined by a circular azimuth curve, and a set of image projectors. The set of image projectors include a radial array of image projectors mounted on the motion platform that project a corresponding series of images via at least one mirror attached to the motion platform onto a convex portion of the toroidal constant vertical resolution surface, and at least one image projector that projects an image on the top surface screen.

  • Publication number: 20160073078
    Abstract: A video projector, a shutter mechanism for a video projector, and a method for providing a visible image and an infrared image. The shutter includes first regions that filter out visible light and second regions that filter out infrared light. The second regions are arranged between adjacent first regions. The shutter can be synchronized with an image modulator that alternately outputs visible light images and infrared images. The infrared images can be viewed using night vision goggles, allowing night vision goggle users to train in a simulated environment.

  • Publication number: 20160073074
    Abstract: A video projector, a shutter mechanism for a video projector, and a method for reducing image blur. A shutter can include regions that are 100% transmissive to light and regions that are more than 0% transmissive (but less than 100% transmissive). The more than 0% transmissive regions raise the perceived brightness of the image relative to a shutter with 0% transmissive regions, enabling the 100% transmissive regions to be smaller. The smaller 100% transmissive regions result in reduced image blur. The more than 0% transmissive regions can include a filter that filters out certain portions of the electromagnetic spectrum of the image to provide a perceived corrected image.

  • Patent number: 9110358
    Abstract: The present disclosure is generally directed to methods of creating and a visual image projection and display system including a tessellation of toroidal constant vertical resolution surfaces to display a single substantially constant vertical resolution image by blending projected images on adjacent constant vertical resolution surfaces. Each toroidal constant vertical resolution surface is defined by any horizontal section of the constant vertical resolution surface normal to a central vertical axis of the tessellation of constant vertical resolution surfaces being a constant distance from the central vertical axis. The system further includes a top surface screen intersecting the tessellation of toroidal constant vertical resolution surfaces defined by a circular azimuth curve, and a set of image projectors corresponding to each constant vertical resolution surface of the tessellation of toroidal constant vertical resolution surfaces and the top surface screen.

  • Patent number: 7130447
    Abstract: A system for tracking a gaze of an operator includes a head-mounted eye tracking assembly, a head-mounted head tracking assembly and a processing element. The head-mounted eye tracking assembly comprises a visor having an arcuate shape including a concave surface and an opposed convex surface. The visor is capable of being disposed such that at least a portion of the visor is located outside a field of view of the operator. The head-mounted head tracking sensor is capable of repeatedly determining a position of the head to thereby track movement of the head. In this regard, each position of the head is associated with a position of the at least one eye. Thus, the processing element can repeatedly determine the gaze of the operator, based upon each position of the head and the associated position of the eyes, thereby tracking the gaze of the operator.

  • Patent number: 6943799
    Abstract: A gaze directed visual system includes a gaze tracker for determining an area of interest; an image generator for generating an area of interest image about the area of interest and generating a background image elsewhere; paired field buffers, for each field of view, for providing a composite image from the area of interest image and the background image; and a timing and control block for interleaving timing of read and write operations on each pair of field buffers whereby reading of the composite image commences upon completion of writing a first portion of the background image so that transport delay is minimized in displaying the composite image on a high resolution display device.

  • Patent number: 4727364
    Abstract: An apparatus for generating computed images on an electronically controlled display surface is provided with an improved intensity shading generator. The shading generator operates by assigning each scan line of a raster display a fixed intensity between first and second points. The sweep position is monitored and each succeeding scan line between an initial position and a break point position of the image is monitored. The sweep intensity is incremented for each sweep line until the break point is reached, at which time new values for intensity are generated. The shading generator of this invention greatly reduces the bandwidth required to generate accurately placed intensity gradients perpendicular to the horizon in a displayed image system.

  • Patent number: 4620291
    Abstract: A digital-to-analog converter interpolator is provided finding application, among others, as a digital ramp smoother. In the preferred embodiment, a regular input step digital ramp signal f(t) is provided as an input signal to a delay line. The delay line is selected so as to have a total delay length equal to an input update period (T) of concern. The output side of the delay line also is adjustable. The delay line voltage output is sampled at intervals of T divided by N over the length of the delay line, where N may be selected to give the desired precision. The sample voltages are summed in a suitable device, and each are given an equal weight of 1/N. The resultant output is a smooth wave form. Structure also is provided for adjusting the gain of the summing device.

  • Patent number: 3996673
    Abstract: An apparatus for generating computed images on an electronically controlled display surface is provided which uses a function module for generating the deflection voltages necessary to display a shape, the shape being defined in terms of right edge and left edge vectors. The vectors comprise line segments, placed end-to-end until a closed shape is formed. Each line segment is defined by a start point and slope to the next vector start point. The shape is constructed by sweeping the beam of a cathode ray device in an X coordinate direction and comparing the instantaneous X coordinate beam position with the instantaneous position of the left edge and right edge vectors. Upon the determination that the beam has passed beyond the coordinate position of the right edge or left edge vectors defining the image, beam intensity is blanked and the Y coordinate of the beam is incremented.
