Abstract: A display device for presenting a virtual image of a product. The device supports an object whose virtual image is to be presented at a point on one side of the device, and an optical system having a transparent member mounted in the manner of a conventional store window. The optical system projects an image of the object in virtual space towards an observer on the opposite side of said device. The device is also equipped with a means for directing an odor towards the image. The odor is scented according to the image being produced. The device is positioned adjacent to a place frequented by potential consumers of the product, such as a street in a shopping area of a town or mall.

Abstract: A visual display system having a plurality of optical systems, defining a viewing area whereby an observer views a continuous field of view in both the horizontal and vertical directions. Each of the optical systems collimate light from an image source to provide an image at infinity focus and an second image which is not focused at infinity whereby the image not focused at infinity increases or decreases in size as the observer moves within the defined viewing area.

Abstract: Apparatus and method for discouraging computer theft. The apparatus and method requires that a password or other unique information be supplied to the computer before the computer BIOS routines can be completely executed. A BIOS memory storing the BIOS routines includes a security routine which will determine whether or not the required password entered by the user, or a known quantity read from an externally connected memory device is present. The security function stored within the BIOS memory also includes an administration function which permits the computer to be either placed in a locked state, thereby requiring password or the known quantity read from an externally connected memory device to be present each time the computer is booted up. The administration function also permits an unlock state which permits the computer boot up process to complete without entering any password or externally supplied quantity.

Abstract: A holographic display system is disclosed. Utilization of holographic elements provides good transmissivity with respect to both outside stimulus and the superimposed display information. Full color display is enabled by a composite spherical lens and the efficient optical coupling of the display information and the pupil allows the weight of the helmet with the display system to be kept to a minimum.

Abstract: A weapon simulator for detecting the azimuth and elevation of which the weapon is oriented, comprising a sign mounted onto the weapon into which a playback sequence of a target path, is displayed through.

Abstract: An optical simulation system comprising a model (12) and collimating optics (16) is disclosed. An image is presented to an observer (32) by means of a plurality of lenses (24, 26) and mirrors optically alligned with the collimating optics. The optics of the system are adjustable so that the range changes of the model can be accommodated without moving large optical elements.

Abstract: A fiber optic helmet mounted display system produces a replica of an image derived from an image source for viewing by an observer. The system includes a wide angle eyepiece mounted on the helmet in the line of sight of the observer. Fiber optic cable means transmit the image from the image source to the eyepiece whereby to produce the replica of the image in the line of sight of the observer, the replica appearing to originate at a distance.

Abstract: This system is designed for video displays that are used for television presentation or film projection, so as to reduce eyestrain, glare from light reflections, and will increase contrast and apparent brightness, making the presentations more readable, and will reduce all potentially harmful radiation effects from the cathode ray tube, which may be cumulative. Primarily, the system consists of an elevated cathode ray tube in the display housing, which produces its image on an inner frontal plane mirror where the image is projected onto and inner spherical morror that reflects the image through a housing cover glass to be seen by the user.

Abstract: An optical simulation system comprising a model (12) and collimating optics (16) is disclosed. An image is presented to an observer (32) by means of a plurality of lenses (24, 26) and mirrors optically aligned with the collimating optics. The optics of the system are adjustable so that the range changes of the model can be accommodated without moving large optical elements.

Abstract: A target designation system for use in training an observer to acquire and recognize targets is disclosed. A scenario with targets is displayed in front of the observer who aligns his line of sight so that a reticle is superimposed on the acquired target. The display system consists of film illuminated by a cathode ray tube. Film is used to provide color, resolution and realism not available from cathode ray tubes or any other display system. Light rays from the display are partially transmitted through a beam-splitter to the observer and partially reflected through an optical window onto a photodetector. In addition, the projected image of the reticle is reflected by the beam-splitter toward the observer. The photodetector and optical window are positioned so that light rays from the scanning spot of the CRT raster impinge on the photodetector only when the scanning spot occupies a point on the CRT screen corresponding to the location on the film at which the image of the reticle is superimposed.

Abstract: An apparatus (10) simulates scenic translation and comprises simulator controls (64) which generate signals (18-26) corresponding to the horizontal position of a vehicle. Video storage unit (12) generates a raster (54) including video information (58) representing a scene to be viewed. A microprocessor (65) responsive to the simulator controls generates control signals for selecting a portion (50 or 52) of said raster corresponding to the position of the vehicle. Horizontal and vertical delay gates (112,114) responsive to the microprocessor select a portion of each line in said raster. A video monitor displays the selected portions.

Abstract: A system for presenting a head-up display to the operator of a vehicle is disclosed. This system comprises a light source fiber optic bundle (52) which is secured to the helmet of the vehicle operator and generates a light beam signal which travels at an angle proportional to the orientation of the pilot's head and, accordingly, his line-of-sight. This beam is detected by a detector (68) which is optically coupled to the light beam and provides line-of-sight information at its ouput. A computer (96) receives the line-of-sight information together with other information and sends it via a cathode ray tube (112) and an optical coupler (14) to a beamsplitter (16) which provides that information to the operator of the vehicle while allowing the operator to see through the beamsplitter (16), thus providing the operator with additional information without obstructing his view.

Abstract: A robotic system for grasping a randomly oriented object, comprising grasping means for grasping said object is disclosed. Motor means places the grasping means at a desired position and causes performance of a gripping function. Camera means forms a first image of the object. An optical train conveys an image from a predetermined point to the camera means, the predetermined point being fixed relative to the grasping means. Image means contains a second image of the object to be grasped. Comparison means compares the first image to the second image. First coupling means couples the image means to the comparison means. Second coupling means couples the output of the camera means to the comparison means. Image rotation means causes rotation of the second image with respect to the image produced by the camera means.
