  • Patent number: 5457575
    Abstract: A combiner is pivotally mounted for movement between an operating position in the line of sight of an operator and a storage position. A sector gear fixed to the combiner engages a slidable rack so that sliding the rack causes pivotal movement of the combiner. A control knob and stem are mounted for rotary movement and translation. A cam rotated by the knob engages followers on the rack to slide the rack upon knob translation or rotation. Knob translation effects movement of the combiner between operating and storage position, and when in operating position, knob rotation effects fine adjustment of the combiner to adjust image position.

  • Patent number: 5414439
    Abstract: A motor vehicle is equipped with an infrared camera for viewing roadway conditions in terms of a thermal image, and outputs a video signal to a head up display (HUD) which projects the camera view to the operator via the windshield or other combiner to display a virtual image in the operator's field of view. The HUD is configured to magnify the image to the same size as the visual or real scene, and compensates for camera and windshield distortion. The virtual image is presented above or below the real scene or may be superimposed on the real scene. A video processor allows selection of only the warmest objects for display.

  • Patent number: 5394203
    Abstract: An opening in a vehicle dash pad allows a HUD reflecting element or mirror to be retracted into the dashboard when not in use. A cover panel hinged to the dash pad supports the mirror and closes the opening when retracted. The panel is joined to a gear arrangement which is controlled by a motor for moving the panel and mirror between storage and operating positions. The mirror is coupled to the panel by a ball joint and the mirror is adjusted about two tilt axes by motor-driven cams for positioning the HUD image in the view of the operator.
