Abstract
Abstract A camouflage and deceptive perception distorted vehicle such as an aircraft or surface vessel or the like for combat use at least a substantial portion of which will remain undetected until the vehicle subtends an arc of substantially five minutes when used against at least one predetermined light background reflectivity in which one of the surfaces of the vehicle includes a substantial area with a predetermined reflectance matching the predetermined light background reflectance. The area includes at least three defined portions at least two of which have different reflectances so that when the reflectance of one defined portion is added to the total reflectances of the others of the three defined portions, and the result averaged, they will have a reflectance substantially that of the predetermined light background.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
269 words
A camouflage and deceptive perception distorted vehicle for combat use at least a substantial portion of which will remain undetected until the vehicle subtends an arc of substantially five minutes when used against at least one predetermined light background reflectivity, hue and saturation comprising: (a) top, bottom, upper and lower side surfaces (b) at least one of said surfaces having at least one substantial edge outlined area (c) said edge outlined area having a predetermined reflectance, hue and saturation less than said at least one predetermined background reflectivity, hue and saturation (d) said edge outlined area including a substantial central portion having substantial width (e) said edge outlined area including a substantial edge outline portion having substantial width and having sections extending a substantial distance along opposite sides of said substantial central portion (f) said substantial central portion and said substantial edge outline portion having differing reflectances (g) said substantial central portion's reflectance being substantially greater than the reflectances of any of said substantial edge outline sections extending along opposite sides of said substantial central portion (h) the total reflectance, hue and saturation of said substantial central portion, when added to the sum of the total reflectance, hue and saturations of said edge outline sections extending along opposite sides of said substantial central portion, substantially averaging to said at least one predetermined light background reflectivity, hue and saturation (i) whereby, when said vehicle is used against said predetermined background, said substantial edge outlined area on at least said one of said surfaces, will substantially match said background and blend said area into said background preventing detection of said area.
Claim 2
Dependent Claim
269 words
A camouflage and deceptive perception distorted vehicle for combat use at least a substantial portion of which will remain undetected until the vehicle subtends an arc of substantially five minutes when used against at least one predetermined light background reflectivity, hue and saturation comprising: (a) top, bottom, upper and lower side surfaces (b) at least one of said surfaces having at least one substantial edge outlined area (c) said edge outlined area having a predetermined reflectance, hue and saturation less than said at least one predetermined background reflectivity, hue and saturation (d) said edge outlined area including a substantial central portion having substantial width (e) said edge outlined area including a substantial edge outline portion having substantial width and having sections extending a substantial distance along opposite sides of said substantial central portion (f) said substantial central portion and said substantial edge outline portion having differing reflectances (g) said substantial central portion's reflectance being substantially greater than the reflectances of any of said substantial edge outline sections extending along opposite sides of said substantial central portion (h) the total reflectance, hue and saturation of said substantial central portion, when added to the sum of the total reflectance, hue and saturations of said edge outline sections extending along opposite sides of said substantial central portion, substantially averaging to said at least one predetermined light background reflectivity, hue and saturation (i) whereby, when said vehicle is used against said predetermined background, said substantial edge outlined area on at least said one of said surfaces, will substantially match said background and blend said area into said background preventing detection of said area.
