Method and apparatus for multiple object viewing
First Claim
1. An instrument display apparatus comprising:
- a transparent sheet,a thin transparent enhancing film made integral with the transparent sheet and which is operable to attenuate preselected wavelengths of light which strike the enhancing film and which originate from all directions, the enhancing film providing unrestricted viewing through the transparent sheet in all directions; and
an instrument to be displayed disposed in proximity to the enhancing film and which is adapted to produce light in the selected wavelengths which are attenuated by the enhancing film whereby the image of the instrument appears in the enhancing film, and wherein the enhancing film further attenuates the selected wavelengths of light which originate from locations other than the instrument whereby the contrast of the image appearing in the enhancing film is improved relative to the background ambient lighting conditions.

Abstract
A heads-up display for moving vehicles such as an airplane or automobile and which includes a transparent sheet which may be the windscreen or windshield of the vehicle. An extremely thin enhancing film is secured in intimate contact with the transparent sheet and disposed within the sheet, if it is a laminated sheet such as a safety glass sheet or on that side of the sheet which is on the interior of the vehicle, or which may be made integral with the composition which makes up the transparent sheet. The enhancing film is an absorber or blocker of selected lightwaves which match the lightwaves of a display of indicia projected against the interior side of the windscreen. The assembly of film in sheet eliminates the need for a separate, independent indicia reflector to replace between the windscreen and the operator of the vehicle.

12. An instrument display apparatus comprising:
-
a substantially transparent panel having a predetermined tint field which attenuates preselected wavelengths of light, and which provides unrestricted viewing in all directions, the tint field attenuating the preselected wavelengths of light which strike the transparent panel from all directions, and an instrument to be displayed positioned adjacent to the transparent panel and which is adapted to produce light in the select wavelengths, and wherein the instrument produces primary and secondary reflected images in the transparent panel, and wherein the primary reflected image is reflected by the transparent panel and wherein the secondary reflected image is attenuated by the tint field whereby the primary reflected image of the instrument appears within transparent panel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. An instrument display apparatus for use by an operator who has a line of sight comprising:
-
a transparent panel, a predetermined tint field made integral with the transparent panel and which provides the operator with unrestricted viewing in all directions and which is operable to attenuate preselected wavelengths of light which strike the predetermined tint field from all directions; and an instrument to be displayed disposed in a position adjacent to the transparent panel and which is operable to produce light in the predetermined wavelengths attenuated by the tint field, and wherein the instrument produces a primary and a secondary reflected image in the transparent panel, and wherein the primary reflected image is reflected by the transparent panel and is substantially unaffected by the tint field and is viewed by the operator along the line of sight, and wherein the secondary reflected image is attenuated by the tint field whereby it is substantially weakened or eliminated, and wherein the tint field is operable to attenuate the predetermined wavelengths of light which originate from locations other than the instrument whereby the contrast of the primary reflected image is improved relative to the background lighting conditions. - View Dependent Claims (22, 23)
