Display system for a head mounted viewing transparency
DCFirst Claim
1. A display system for a head mounted viewing transparency, said transparency defining a field of view for a user comprising:
- means for supporting said transparency to mount said transparency on a user'"'"'s head;
means for displaying information, said display means being mounted on said support means; and
mirror means for collimating light to project an image of said displayed information at a distance from said user in the periphery of said field of view, said mirror means receiving said information directly from said display means and being positioned in the periphery of said field of view to allow said user to view said image through said mirror means.

Abstract
A display system for conventional eyewear having a transparency that defines a field of view and a frame for supporting the transparency on a user'"'"'s head is shown. The display system includes a light transmissive display mounted on the frame of the eyewear and optics for collimating light to project an image of the displayed information at a distance from the user in the periphery of the field of view defined by the transparency. The optics may include a single mirror that receives the information directly from the display wherein the mirror is toroidal or the like so as to project an enlarged image at an apparent optical distance from the user that is greater than the actual optical path. Alternatively, a planar mirror may be employed with a collimating lens to project the image at a desired distance from the user. The mirror may be fully reflective or partially reflective so as to superimpose the image of the displayed information on the scene viewed by the user through the transparency of the eyewear. Further, means are provided for automatically adjusting the optical path defined by the relative position of the mirror, the display and the user'"'"'s eye to accommodate heads of various sizes.

31. A display system for a head mounted viewing transparency said transparency defining a field of view for a user comprising:
-
means for supporting said transparency to mount said transparency on a user'"'"'s head; means for displaying information, said display means being mounted on said support means to integrate said display means into said support means; mirror means disposed in the periphery of said field of view at a position relative to said display means for collimating light to project an image of said displayed information at a distance from said user; and means for adjusting an optical path defined by the relative position of said mirror means, said display means and an eye of the user to accommodate heads of various sizes. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 60)

54. A display system for a head mounted viewing transparency used in performing an activity that in part requires focusing at a distance that is less than infinity, said transparency defining a field of view comprising:
-
means for supporting said transparency to mount said transparency on a user'"'"'s head; means for displaying information, said display means being mounted on said support means; and mirror means disposed in the periphery of said field of view for collimating light to project an image of said displayed information in the periphery of said field of view and at a distance from said user that is less than infinity to allow a user to rapidly, visually accommodate said projected image while performing said activity part. - View Dependent Claims (55, 56, 57, 58, 59, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
