Abstract
Abstract A miniature daytime dynamic alphanumeric/graphic flight symbology generator and display system in which raw aircraft data, such as altitude, airspeed, heading etc., are generated by a display generator into symbology indicating the data intensity. The symbology is transmitted by a signal transmission means, to a symbology image source by a means such as fiber optic links in case of optical signals or flexible cable in case of electrical signals. The symbology from the image source is projected onto a combiner directly in the line of sight of the aviator so that symbology indicating the various conditions of the aircraft is viewed by the aviator as an overlay with the actual scene. The combiner is enlarged to provide a 30° field of view and has a spectral coating thereon to enhance the symbology for daytime viewing. The display generator has a variable control means to increase the data intensity for daytime viewing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
175 words
A miniature dynamic alphanumeric and graphic flight symbology generator system for use in a heads up helmet mounted display daytime environment, said system comprising: a display generator having various inputs thereto from raw aircraft data and internal signal generating means providing various output signals therefrom in direct relationship to the aircraft data and variable signal control means to increase the value of said output signals during the daytime to provide daytime observance of the symbology generated; a symbology image source which has a luminance in direct relation to said output signals applied as inputs thereto through a signal transmission means from said display generator to said symbology image source; and a beam combiner means positioned in the line of sight of at least one eye of an aviator, said beam combiner means comprised of focussing optics and a mirror positioned at an angle to reflect the display on said symbology image source directly back into the eye of the pilot wherein said mirror has a spectral coating thereon for enhancing the image for daytime viewing.
Claim 2
Dependent Claim
175 words
A miniature dynamic alphanumeric and graphic flight symbology generator system for use in a heads up helmet mounted display daytime environment, said system comprising: a display generator having various inputs thereto from raw aircraft data and internal signal generating means providing various output signals therefrom in direct relationship to the aircraft data and variable signal control means to increase the value of said output signals during the daytime to provide daytime observance of the symbology generated; a symbology image source which has a luminance in direct relation to said output signals applied as inputs thereto through a signal transmission means from said display generator to said symbology image source; and a beam combiner means positioned in the line of sight of at least one eye of an aviator, said beam combiner means comprised of focussing optics and a mirror positioned at an angle to reflect the display on said symbology image source directly back into the eye of the pilot wherein said mirror has a spectral coating thereon for enhancing the image for daytime viewing.
Claim 3
Dependent Claim
33 words
The system as set forth in claim 1 wherein said symbology image source is a miniature cathode ray tube and said signal transmission means is a flexible cable interfacing with said display generator.
Claim 4
Dependent Claim
48 words
The system as set forth in claim 1 wherein said signal transmission means is a coherent fiber optic bundle for transmitting optical signals from said display generator to a display within said image source wherein said optical signal is projected by a reticle projector onto said combiner means.
