DETAILED DESCRIPTION
[0102] Objects are either not visible; when they blend into the background (=camouflage) there is no distinction between the object and the background, or they are always visible against a background. The terms “positive” and “negative space” which O'Neill et al. use in the U.S. Pat. No. 6,805,957 are dubious since they are random definitions but not natural conditions. For example, while one may in fact have the impression from a distance of 100 m that the space between two trees (=“positive space in the sense of the above definition”) is empty (=“negative”), from a distance of e.g. 30 m the same space tends to be filled with slim trunks, branches, leaves, etc., which would again be a “positive space” in the above sense. Thus, every object of the body's background e.g. a tree can always be broken down, in relation to the distance of the observer, into an infinite number of sub-objects (from far to near: dark spot, then tree, then foliage, then leaves and branches, then bark, leaf veins, leaf stems, etc.). However, the claim of the camouflage system according to the invention is not limited to one distance but to the contrary it can be continuously employed at any distance. The terms of “positive and negative space” thus do not appear consistent nor logical per se, they are thus at best partially applicable. It appears more conclusive in terms of logic to describe the background properties viewed as an area.
[0103] For one since no other option is possible of illustrating on a surface, thus two-dimensional, e.g. a clothing suit which is anyway always an area enveloping a body, or e.g. a vehicle as an object to be camouflaged. This also applies to “ghillie suits”. These are special camouflage suits primarily used by snipers, consisting of camouflage nets with additional materials inserted, such as burlap or twigs. All of these are perceptible as an object from short distances at ca. 20 m to 30 m, although with a structured surface. This is the very characteristic of camouflage, to image on a surface something other than is actually present in the object. This means in other words that the object does not consist of the same materials and structures as the background. Camouflage of a surface would then be substantially superfluous. What is significant is configuring the surface so as to make the object appear as does the background, whether or not it consists of the same materials as the background. Examples from wildlife of camouflage similar to a “ghillie suit” include e.g. some crabs growing algae on their bodies, or flies which build tubes from pebbles in their surroundings.
[0104] For another because a projection on the human retina is always a two-dimensional image which the brain ultimately computes into a three-dimensional image due to two-eyed vision. This is where a wide range of optic illusions are possible. Even if stereoscopic vision is not given when looking through a sighting telescope or in imaging on the screen of a thermal image converter/night vision device etc. due to absence of direct binocular vision of object and background (usually one looks through a sighting telescope with one eye, and a screen is again a plane).
[0105] In summary, with signals captured as visible light, infra red, UV etc. in a processing chain (eye/brain, image processing/optical aids), one two-dimensional image per eye will ultimately primarily always be generated from which the brain forms a three-dimensional image, for evaluation. What is decisive is that it is irrelevant whether the captured signals originate from a three-dimensional object or a two-dimensional, patterned object or a structured surface: A two-dimensional image will be created.
[0106] Viewed in this way, the subject (=observer) will perceive both the object and the background as areas. This requires pick-up and description of the object and background as areas. What is conspicuous is thus differences between the object and background imaged through the electromagnetic spectrum in the signature features substantial for signal pick-up, below called pick-up features for short. Features such as smell, taste, noise, will presently be disregarded.
[0107] The optical pick-up features will be described below using the background as an example. For camouflage the communication between object and receiver must be interfered with and the perceptible features, in this case the surface of the object to be camouflaged, must be such that they are identical with that of the background in as many of these features as possible, masking the character of the object.
[0108] The background, viewed as an area, can be described by the pick-up features indicated below. These can be understood as a mode between two poles of extremes. The most extreme cases are: a signal is incident on the receiver, and no signal is incident on the receiver. The feature modes tend to be present in fuzzy transitions. What has just been described is elementary for the effect described below. Examples of these features occurring in nature are indicated in brackets: [0109] 1. Light-dark (shadow, light, counterlight), [0110] 2. Color spectrum (e.g. from brown to green, for example camouflage suit for verdant terrain). This area designation is simplified to more clearly characterize the extreme poles. For this application, shades of brown include e.g. gray, yellow, and red hues. It will be understood that other backgrounds such as cold deserts or hot deserts have other extreme color poles, [0111] 3. Patterns; even if ultimately every image can be mathematically composed of dots, human, macroscopic view makes this distinction: line-spot, [0112] 4. Contrast; contrasts or transitions may exist between the color areas, [0113] 5. Saturated (lush leaves, wet foliage) and unsaturated (dry branches, dry foliage) colors, [0114] 6. Warm colors (though very subjective), e.g. autumn leaves-cold colors such as fresh leaves, [0115] 7. Glossy colors, e.g. wet leaves-dull colors, e.g. dry tree bark, [0116] 8. Invisible radiation (e.g. UV, heat, infra red, radio waves).
[0117] The significance determined by the practical relevance for the application decreases with ascending number. Item 8 is an exception thereof since it gains increasing significance in present-day fighting fields. The first five items are substantial, the first two items are essential for practical application in the field of camouflage clothing: Light-dark and colors can be perceived from longer distances than can structures. Item six is very subjective and difficult in application to be relevant in practice. Item seven may include specific applications e.g. at sea, reflections of the sea surface.
[0118] For all of the items it is important that the smallest possible range of camouflage means, in the present example printed colors, must cover the entire conceivable background property space. This is significant not only to minimize costs but primarily because the separation efficiency of perception is intended to be deceived by the 50% rule. Applying this 50% rule, approximately 50% of the area to be camouflaged are configured in each of the background properties in the most extreme possible mode of one of the poles of a background property but not as was usual to date, a medium color of the property and approximately 50% in the diametrically exactly contrary property mode. For a suit for verdant terrain this means a distribution 50% light-50% dark, 50% brown-50% green, 50% lines-50% spots. Care should be taken for these zones to not be congruent such as light =brown or dark =green, but again that 50% of the light area be brown and 50% green, and likewise regarding the dark and line/spot structures. Using the smallest possible number of properties is important because, when for example too many similar brown hues are used over the others, one of which is, however better matched to the background property, the latter will be conspicuous (=relativity of conspicuousness).
[0119] The object or the item visible against the background, in other words the object to be camouflaged, can be classified in respect of its mobility in [0120] 1. Objects stationary in location and posture and shape such as hunter's hides, bunkers, etc. [0121] 2. Objects non-stationary in location (=mobile) though fixed in posture and shape, e.g. ships, vehicles, where e.g. the top surface is always on top and the bottom, always at the bottom. [0122] 3. Objects non-stationary in location and posture and shape such as humans, animals, mobile/deformable items such as parachutes.
[0123] The objects indicated under 1. can basically be perfectly matched to the specific backgrounds at the time in all the characteristics and from any viewing angle, the shape/structure/the material can be matched as well among other things by structural measures (e.g. planting).
[0124] In the case of mobile objects (2. and 3.) the shape/structure/material is derived from its function (e.g. stealth bombers, swiveling tank turret and its washability of ABC matter, hunter's bow and arrow) and most of these cannot be camouflaged in shape/structure/material without loss of function and restriction of movement. This will be exemplarily clear in particular with camouflage clothing as distinguished from so-called ghillie suits which, although largely allowing structural adaptation to the surroundings, are adapted involving restriction of movement, increased weight, and increased noise level, and often restricted vision and hearing.
[0125] A camouflage pattern, however, allows 100% mobility, is cheap and comparatively simple in manufacture compared to more complicated methods such as e.g. “ghillie suits”, incorporating radiation sources, e.g. LEDs, nano-technology, attaching water nozzles to create water curtains for ships, to match the emission of the object to that of the background.
[0126] Moreover, and this is essential, mobile objects are positioned against constantly changing backgrounds. These changes are related among other things to the time of day and the season, the angle of observation, e.g. from above, from the side or the bottom, to the distance of the observer (changes in the proportions and structures, e.g. a tree looks like a green area from 100 m distance, from 20 m distance one recognizes gray branches, dark shadows and green foliage in this green area etc., local zones next to one another in the visual field of an observer, and changes in the surroundings (woodside, softwoods, hardwoods, sandy/verdant ground, grass, in front of/next to a tree). These changes, which is again essential, do not only occur between different “tactical surroundings” (e.g. “woodland”, “urban”, “desert”), as is often generally suggested, but to a high degree within these. It may happen that in some places e.g. dried grass, river banks etc. in temperate zones desert-like color spaces occur with lush green grass being immediately adjacent thereto.
[0127] Furthermore, it is not acceptable to assume axes of symmetry. In the case of objects movable in themselves, e.g. humans, a person will hardly ever take a symmetric posture. When regarding a human as a two-dimensional area against a two-dimensional background area, there will in most cases be an asymmetric, two-dimensional illustrative area in movement/dynamic. The same holds in most cases for objects not movable in themselves (e.g. vehicles, ships) which appear as an asymmetric area due to the viewing angle. Humans are still symmetric in their macroscopic anatomy although in the image that the observer knows, not in the posture/situation he can specifically see at the time.
[0128] Any object will be 100% invisible only if it is 100% identical with the optical pick-up features of the background. This will function only in the case of a constantly changing adaptation and if the object itself had no bulk. Since due to the permanent configuration of surface finishes this is not feasible in practice but it may be, due to automatic emission of radiation or active camouflage techniques, the scope of passive camouflage techniques has thus far only offered the way of color mixture which, however, shows the drawbacks indicated above.
[0129] The invention takes a different approach:
[0130] Based on the above statements it is logical that the observer will at any rate only have a purely optical perception of the object (subconscious process). The only question is how much he sees, how he sees, and whether this is sufficient for drawing his attention (developing awareness) towards the object. This is because proper recognition first requires purely optical perception, then selective and concentrated attention, and then evaluation/decision. The purely optical being seen (optical signals are incident on the retina) per se is not a problem for the object.
[0131] Attention will be particularly drawn as: [0132] a large area is seen, [0133] a regularly shaped area appears (primarily parallelograms e.g. pants legs), [0134] clearly recognizable areas move, in particular fast.
[0135] Another condition is essential as well: the relativity of conspicuousness.
[0136] Against a defined background area in specified modes having the properties indicated above, of two same-size and same-shape areas adjacent to one another that one will be more conspicuous against said background area that deviates in its background properties more than the other from the shared background area. Attention will always first be drawn to the more conspicuous area. The other area will recede in relative attention.
[0137] What is decisive is the relative difference. The effect will occur for example when one places against a black area a light gray (more conspicuous) and a dark gray (less conspicuous) area, see
[0138] The camouflage pattern area 1 is configured such that in each of the background properties (see above) approximately 50% of the area to be camouflaged are configured in the most extreme mode possible of the background property and approximately 50% in the diametrically exactly contrary mode. For example, for a suit for verdant terrain: 50% light-50% dark, 50% brown-50% green. What is provided is, a light property band 2a and a dark property band 2b, a brown property band 3a, and a green property band 3b. Care should be taken for these property bands 2a, 2b, 3a, 3b to not be congruent such as light=brown or dark=green, but again that 50% of the light area be brown and 50% green, and in analogy regarding the dark and line/spot structures. This will be achieved by superimposing the property bands 2a, 2b, 3a, 3b in such a way that intersections, so-called zones, will appear.
[0139] Furthermore, the brown and green property bands 3a and 3b extend in parallel as irregular color bands. The light and dark property bands 2a and 2b again extend as parallel, irregular property bands 2a and 2b although angled relative to brown/green such that these four property bands 2a, 2b and 3a, 3b intersect and superimpose one another so as to make up light green, light brown, dark green, and dark brown spots, the so-called zones. In the exemplary embodiment the borderline is formed as spots at one of the borderlines between brown and green. The next of the borderlines between brown and green will then be formed by lines. The borderline “contrast” extends along one of the borderlines between light and dark. The borderline “transition” extends along the other of the borderlines between light and dark. The property bands 2a, 2b, 3a, 3b are furthermore defined irregularly so as to impede the observing of movement.
[0140] What is particularly conspicuous are elongated parallelograms (primarily extremities) which with the described method are consequently subdivided into smaller areas with no spatial direction (quadrangles, or better a disk as an extreme sample of absent spatial guidance for the eye, compared e.g. to a rectangle which will have a direction in space when “lying”). The pattern areas indicated above should be distributed such that a body is no longer recognizable as such in any position or pose.
[0141] The principle of the property bands 2a, 2b, 3a, 3b begins in the large pattern areas (e.g. “light/dark”) and continues down to the smallest pattern areas in the sense of a fractal (e.g. separately illustrated branches/leaves). Furthermore, due to the interweaving to obtain a fractal pattern relative to the zone size, blending into the background is possible at any distance. For example, at long distances some green bushes may appear as dark spots on the horizon. At short distances one will recognize shadows and foliage. At close distance, leaves and branches. The pattern reflects this.
[0142] Furthermore, due to this approach the technique of the surface treatment specification is self-defined in analogy to a mathematical equation. It quasi grows along with the size of the object to be camouflaged. It can thus be applied to bags and camouflage clothing as well as to tanks, aircraft, and ships.
[0143] The object to be camouflaged is not treated on the basis of axes of symmetry but based on the substantial object areas of the essential portions of the object. These are the large, geometric base areas of which the object area is composed when viewed from a visual angle. The large object areas, using the human body shape as an example, are formed by the head, torso, and the four extremities. In the case of a tank these are e.g. in a side view, the body trough with the chassis, the side view of the turret, and the barrel. Due to the unstable shapes of objects movable in themselves, e.g. humans, axes of symmetry can be determined based on anatomy though not in the actually assumed posture which tends to be an asymmetric area and moreover changes from one moment to the next.
[0144] This is why the areas of an object to be camouflaged are reduced to those areas that are substantially movable relative to one another though stationary (relative to their position in the entire object; object areas). In the case of humans this means for example the arms, legs, torso, and head but not e.g. the foot or lower leg relative to the thigh. In the case of a tank, however, only the turret and the barrel are movable relative to the trough and the chassis. This is why in a lateral view it consists of only three areas movable relative to one another though stationary: barrel, turret, chassis with trough. Ships substantially have one lateral surface only, as does aircraft. Still, the fractal pattern structure results in a further subdivision of the individual, smaller object parts. For example, a gun turret located in the dark field of a ship's camouflage will again be subdivided into single areas and treated by the 50% rule as described above, thus it will be broken down not only against the background of the sea/the sky but against the entire ship as well. On the whole it will remain dark though and thus associated with the superimposed dark field.
[0145] The extent to which this fractal approach is elaborated, depends on the intended possible nearness to an observer up to which the object is to be camouflaged from him.
[0146] The size of the repeat pattern will depend on the object to be camouflaged. This can best be achieved by way of approximately applying the 50% rule described above to each of these areas, e.g. 50% of the leg light brown, 50% dark brown and 50% light green and 50% dark green, such that large zones of contrasting background properties occur in the object. Thus far, suits have always had small-portion patterns such that a large number of spots of the same property are present in each of the specified separate areas of the body. This is why the following will happen against a dark background: The light spots will become visible, the dark ones recede in comparison. A conventional suit is e.g. provided with visible light brown spots on the entire leg spaced apart e.g. 5 cm each. Thus the leg will be quasi highlighted like a warning signal against the dark background as a leg in its entirety, since many similar optical stimuli occur in regular distances so as to produce a contour line, since in this way the visual stimulus triggers will be observed as one unit, in particular with movement in synchrony.
[0147] With the present invention, however, for example only the lower leg will be perceived as light while the thigh will recede. The entire leg is not recognizable as a leg but only a light spot is (lower leg). Since light spots will always also appear in dark areas, this might as well be e.g. a sunlit tree stump. Since this will not be associated with a human body but will be perceived as a natural occurrence and thus not menacing, it will not be actively observed. Another example is a “brown branch” in front of a “green bush” or “green plants” on “brown forest soil”. In contrast thereto, an olive (being a blend of brown and green as it appears in conventional suits) leg would be as conspicuous against a green bush as against brown leafy soil.
[0148] What is furthermore important is the proportions of the areas and the spatial arrangement of the areas.
[0149] The spatial arrangement must match the structure of the surroundings. Furthermore, it must be inconspicuous against the background in each position/posture (standing, lying, squatting, lying prone/on the back) and from every visual angle. The repeat pattern must furthermore be ensured. Also, the area for printing should be subdivided into the largest possible sub-areas.
[0150] In verdant surroundings for example implementing these specifications has proven optimal by way of a layout inclined approximately 45 degrees e.g. relative to the human longitudinal body axis. Regardless of how the suit is cut and what position (posture, standing, lying) the wearer takes, the zone lines will blend into the surroundings and their perspective distortion. In urban surroundings, however, partial lines parallel to the principal body axis have been incorporated. Right angles are avoided, however, to create a spatial-perspective impression and because they hardly occur in nature and in urban regions when their image is regarded in perspective as a plane, and would thus draw the attention of an observer. In primarily horizontally structured surroundings (desert/sea) the described automatic blending of the pattern into the object results in an appropriate formation until it masks e.g. the side view of the ship.
[0151] Furthermore, the property band borders are designed in a line approximately 50% as transition and 50% as contrast since both contrasts and transitions occur in nature. Existing suits have thus far, at a specified distance from the observer, imaged either contrasts only (e.g. WWII Splintertarn, US “woodland”, Predator™) or transition (BW Flecktarn, MARPAT, CADPAT, ARPAT).
[0152] The pattern proper, i.e. whether it images leaves, grasses or spots, or abstract shapes such as pixels, is of secondary significance. These structures can be recognized in precise detail only at very close distances. In this range even e.g. buttons are recognizable which are therefore consistently avoided in applying the invention to camouflage clothing as presently set forth exemplarily for applying patterns. What is significant is, however, the spatial proportions of the areas. They must match the background in rhythm, with a fractal adaptation to lengthening/shortening distances. This is not present for example in the woodland suit or splinter suit or BW-Flecktarn. The subdivision of the pattern areas into lines and point-shaped color spots is to be understood in this sense.
[0153] Another advantage of this virtual independence of a pattern is the fact that it can be incorporated into existing camouflage patterns which can thus be significantly improved. This is important for example for maintaining “corporate identity” e.g. of an army by their uniforms, and likewise of police, recreational teams, etc. In fashion applications such as patterns from script, Scottish plaids, this approach is again conceivable. Furthermore, costs can be saved. Incorporating is understood to mean that the theme of shapes of the existing pattern is adopted and it will only be rearranged according to the principles indicated in the invention.
[0154] The pattern theme is significant, e.g. leaves or pebbles, if absolute perfection in camouflage is desired at ultra-close distances less than ca. 10 m and/or specialization, e.g. urban suit for counterterrorism units. For a suit intended for largely verdant terrain (jungle, temperate zones, e.g. central Europe) having eight background poles (light-dark, brown-green, spot-line, contrast-transition) at least four colors are thus required (light/dark brown and light/dark green) to ensure such a structure. A specific exemplary embodiment includes eight colors since this allows to elaborate starker contrasts between the colors and thus better structures along with better matched transitions. These eight colors have been elaborated in years of work from the naturally occurring colors worldwide and have been found to be a well-balanced mix (neither too many nor too few): [0155] Light: palest green, sand [0156] medium: green medium, autumn-leaf orange [0157] medium dark: bark gray, [0158] dark: green dark, [0159] very dark: brown dark [0160] darkest: black
[0161] For suits for largely barren terrain (snow/hot/water/sky “deserts”) employing more scintillating effects has been found more useful, i.e. more smaller areas with borders made fuzzy by scintillation, i.e. less sharp transitions between the large areas composed of the small spots, than in verdant terrain. This means that the suit is specifically manufactured for vegetation zones, meaning e.g. for central Europe or for deserts or jungle or alpine or polar regions. This means that repeated changing of clothes is dispensed with as it has been required with hunting clothes thus far e.g. in changing from brown to green or oak to conifer forest. On the other hand the suit will, unlike existing suits, cover these vegetation zones more completely. This means that the camouflage effect achieved will be better in different seasons and against different background sub-areas (brown, green, light, dark, leaves, bark, trunk, pebbles, grass, sand) occurring in a vegetation zone e.g. in central Europe.
[0162] The following further colors are considered to be incorporated into the above canon of eight colors for adaptation to other color spaces. What is important is that this is an intermatched, modular color system for the family of camouflage patterns with their illustrated proportions as set forth presently as an example of an application of the invention. This is why these colors can be exchanged for one another. What is also conceivable is expanding the color space to meet specific requirements or developing other color spaces, as long as the described principle of pattern development is maintained. The color space developed thus far is: [0163] Lightest: snow white, [0164] very light: autumn yellow, urban white, [0165] light: desert pink, sand, green lightest, snow gray, [0166] medium light: grass yellow, urban gray, [0167] medium: green medium, autumn-leaf orange, brick red urban brown, [0168] medium dark: bark gray, autumn red [0169] dark: green dark, [0170] very dark: brown dark, asphalt gray, [0171] darkest: black.
[0172] Preferred applications provide for absence of fuzzy color transitions in favor of full strength colors since stark contrasts of adjacent, different-size spots result in a “scintillating effect” similar to a zebra pattern. This makes it more difficult to capture borders and posture of individual object parts relative to one another. This prohibits a correct assessment of distances from an object, of movement, direction of movement, bulk, posture, position, and recognizing e.g. the type of vehicle, in analogy to “dazzle painting” employed in the first and second world wars primarily on warships.
[0173] Various specialized applications are conceivable for specific tactical backgrounds or else for hunting. For example for hunting in winter grassland/reed: stark contrast borders are absent, the structure almost solely consists of lines with hardly any spots. The color space is limited to brown-gray-yellow hues.
[0174] The principles indicated above are likewise applicable to infrared, near-infrared, radio wave, UV, and thermal ranges, since the backgrounds e.g. rocks next to trees are once again variable in their radiation response, creating zones.
[0175] The concrete application of the present invention leads to the design of a new cut for camouflage suits to optimally present the pattern while being highly ergonomic. Ergonomics in the sense of facilitating movement is essential for surviving against the background of acting under high physical and psychic stress. It is therefore necessary to use the largest possible uninterrupted pattern areas with the fewest possible breaks e.g. by seams, sew-on badges, pockets, zippers, buttons, or protectors. For this reason the pants legs and sleeves, and the back are made from one piece only and with inside zippered pockets, no pocket flaps, and with the seams underarm and on the inside of the legs.
[0176] Cutting patterns have thus far cut up designs, see U.S. Pat. No. 6,805,957. The suits in use thus far have been cut up by way of fabric areas combined from many fabric pieces with outside pockets, pocket flaps, etc. Also there are often belt carriers, carrier vests, splinter protection vests, protectors, ABC-bags, ammunition bags etc., worn over the suit. These tend to be colored differently such as olive and/or black, which attenuates or cancels out the camouflage effect of the suit (e.g. black vest over desert camouflage suit) or printing is attempted. Although the latter is better than black or olive, the problem of a small-area pattern remains unsolved and added efforts and costs are involved.
[0177] It is thus the primary objective of the invention to create the largest possible continuous fabric areas. This is achieved by avoiding seams as far as possible (pants legs, coat sleeves, and coat front/back are all one-piece). There are only concealed pockets constructed with zippers. Pocket flaps are not used. There are no buttons or protectors disrupting the pattern on the outside. The pattern is thus just minimally disrupted. For practical application, a camouflage pattern area size is illustrated having a repeat pattern of the basic scheme between approximately 0.6 m and 1.0 m in width and between approximately 0.8 m and 1.3 m in length, as illustrated in
[0178] A configuration as an integral suit provides transporting capacity for belt carriers, ABC protection, splinter protection, ammunition, water, and communication (radio etc.) and personal items. Thus there is no requirement for extra transporting vests, belt carriers, and ammunition/ABC bags. The splinter/ballistics/stabbing protection vest is worn beneath the camouflage suit; underneath that, water/wind protection, underneath, cold insulation as required, and underwear underneath. In this way a modular composition of clothing related to the application is achieved. In this way freedom/efficiency of movement is enhanced. Less clothing reduces weight. Some pockets, for safely carrying documents, are watertight. Knee and elbow protectors are attached inside or on the coat/pants so as to not disrupt the pattern.
[0179] The coat/pants and thus camouflage can be selected by the intended application. No summer/winter coats/pants are required since adaptation to weather occurs by way of the layers underneath. Thus the coat/pants are “only” required for optical, physical (thorns, tear, wear, abrasion to elbows/knees) and transportation functions, optionally electronics and possibly BNIC (biological, nuclear, incendiary, chemical) protection. It is highly breathable, quick-drying, and dirt-repelling. The colors of the camouflage suit do not change when wet or dirty.
[0180] Another advantage is that through pockets and oversuits are dispensed with. All of the equipment items are fast, easy, silent, single-handed, and accessible from the outside. Furthermore, the risk of getting caught on obstacles (branches, wire barriers, in parachuting, etc.) and the associated risk of detection (bush moving along, noise) and damage to equipment/the suit (buttons lost, pockets slit open, etc.) is reduced. Employing zippers furthermore allows loss-proof transportation of equipment.
[0181] The use of elastic materials and partitions in the pockets prevents the rattling of parts lying loose in the pockets and allows easy, quick, and organized access. The suit allows the attachment of camouflage materials to camouflage holders which do not disrupt the pattern, in anatomically functional places. This allows optimized camouflage. By means of precise, strategic placing of holders in anatomic key positions (head, shoulders, upper arms, back, sides and rear of thighs, rear of lower legs) there is no impediment as in ghillie suits to freedom of movement, vision, and noise camouflage. Furthermore, camouflage material can be saved and weight thus be reduced.
[0182] The scheme area 1 is configured as a quadrangle with the quadrangle side lengths corresponding to the maximal height or maximal width of the object to be camouflaged and/or the area to be camouflaged, said quadrangle serving as an aid in configuring the camouflage pattern area according to the invention. To this end a diagonal 4 or 7 is used through the quadrangle midpoint and two straight lines 8 and 9, or 10 and 11 extending in parallel through the side length midpoints. Thus the diagonal 4 or 7 and the straight lines 8 and 9 or 10 and 11 form pairs of parallel property bands 2a and 2b or 3a and 3b. These parallel property bands 2a, 2b or 3a, 3b may also be displaced parallel to the diagonal 4 or 7. These property bands 2a, 2b or 3a, 3b differ in one property mode wherein the property is expressed alternatingly in pairs of different degrees of lightness, color, saturation, pattern, structure or gloss. The diagonal 4 or 7 and the straight lines 8 and 9 or 10 and 11 form borderlines. Said borderlines of the property bands 2a, 2b, 3a, 3b may be configured continuously or discontinuously, high in contrast, or as fuzzy transitions. The borderlines between the pairs of property bands 2a, 2b, 3a and 3b may thus be configured alternatingly as a contrasting line 5 and/or as a fuzzy transition 6. The property bands 2a, 2b, 3a, 3b are defined irregularly or regularly. However, each property band 2a, 2b, 3a, 3b is in itself homogenous in one property mode. In this way one property of the camouflage pattern area 1 is present 40 to 60%, preferably 50% each in one mode and 40 to 60%, preferably 50% each, in another mode.
[0183] In another embodiment the scheme area 1 is configured as a quadrangle as in the preceding example. As a specific feature a straight line 12 extends through the midpoint of the quadrangle parallel to the side edges. In this way two parallel property bands 2a and 2b are formed. The parallel property bands 2a and 2b may again be displaced parallel to said straight line 12. The parallel property bands 2a and 2b extend horizontally or vertically. Furthermore, this quadrangle possesses a diagonal 4 or 7 and two straight lines 8 and 9 or 10 and 11 extending in parallel through the side length midpoints, and thus additional parallel property bands 3a and 3b differing alternatingly only in one property mode as do 2a and 2b. The parallel property bands 2a and 2b may be displaced parallel to the straight line 12 which extends through the side length midpoints. The parallel property bands 3a and 3b may likewise be displaced to the diagonal 4 or 7. These property bands 2a, 2b, 3a, 3b again differ in one property mode wherein the property is expressed alternatingly in pairs of different degrees of lightness, color, saturation, pattern, structure or gloss. The diagonals 4 and 7 and the straight lines 8, 9, 10, 11 and 12 may be configured as in the preceding embodiment as borderlines of the property bands 2a, 2b, 3a, 3b, continuously or discontinuously, high in contrast, or as fuzzy transition. The borderlines between the pairs of property bands 2a, 2b, 3a and 3b may thus be configured alternatingly as a contrasting line 5 and/or as a fuzzy transition 6. The property bands 2a, 2b, 3a, 3b are likewise defined irregularly or regularly. However, each property band 2a, 2b, 3a, 3b is in itself homogenous in one property mode. In this way one property of the camouflage pattern area is present 40 to 60%, preferably 50% each in one mode and 40 to 60%, preferably 50% each, in another mode.
[0184] To further enhance camouflage, another embodiment provides for the scheme area 1 to also be configured as a quadrangle. Again the side lengths of the quadrangle correspond to the maximal height or maximal width of the object to be camouflaged and/or of the area to be camouflaged. This quadrangle possesses two intersecting diagonals 4 and 7 extending through the quadrangle midpoint and four straight lines 8, 9, 10 and 11 extending in parallel through the side length midpoints and thus forms parallel property bands 2a, 2b and 3a, 3b, with the property bands 2a and 2b extending parallel to the diagonal 4 and the property bands 3a and 3b, parallel to the diagonal 7, and the property bands 2a, 2b, 3a, 3b differ alternatingly only in one property mode. These parallel property bands 2a, 2b, 3a, 3b may be displaced parallel to the diagonals 4 and 7. The property of these property bands 2a, 2b, 3a, 3b are present in alternating modes in two different degrees each of lightness and/or color and/or saturation and/or pattern and/or structure and/or gloss and each property band 2a, 2b, 3a, 3b is per se homogenous in said property. In this way one property of the camouflage pattern area 1 is present 40 to 60%, preferably 50% each in one mode, and 40 to 60%, preferably 50% each, in another mode. The diagonals 4 and 7 and the straight lines 8, 9, 10, and 11 are configured as borderlines of the property bands 2a, 2b, 3a and 3b, continuously or discontinuously, high in contrast, or as fuzzy transition. The property bands 2a, 2b, 3a and 3b are defined irregularly or regularly. The borderlines between the pairs of property bands 2a, 2b, 3a and 3b may thus be configured alternatingly as a contrasting line 5 and/or as a fuzzy transition 6. However, each property band 2a, 2b, 3a, 3b is in itself homogenous in one property mode.
[0185] The angle of the intersecting property bands 2a or 2b and 3a or 3b may be between above zero degrees and beneath 90 degrees. The pairs of property bands 2a, 2b and 3a, 3b of same property extend in parallel.
[0186] The camouflage scheme can be transferred to existing camouflage patterns and/or incorporated into existing camouflage patterns. The camouflage scheme can furthermore be applied to the entire spectrum of electromagnetic waves. In special cases the camouflage pattern may extend continuously over the surface of the object to be camouflaged without interruption. It does not matter how the pattern is generated (printing, spraying, nano-technology, electronics, radiation).
[0187] To achieve a consistently good camouflage effect independently of the distance between object and observer, zones may be generated by superimposing pairs of property bands 2a, 2b with intersecting pairs of property bands 3a, 3b, representing intersections of the pairs of property bands, these zones can then be divided further into sub-zones, again by means of intersecting parallel pairs of property bands which sub-zones are then again subdivided into sub-sub-zones, and so forth. In this way fractal interweaving is obtained that may be continued infinitely so as to result in a continuous camouflage effect across any distance. This fractal interweaving is illustrated in

[0192] To complete the camouflage scheme or pattern 20, at least two second bands 34 (34a, 34b, 34c, 34d) each having a second length and a second perceptible characteristic, each extend generally diagonally across the entire area 24 in a second direction 36, where the first and second directions are different. It should be appreciated that the second bands 34 may extend horizontally, vertically, diagonally or at any suitable angle across the area 24. In the illustrated example, the second perceptible characteristic is shading, i.e., changing the lightness or darkness of a color, pattern, etc., where the second bands 34 include lighter and darker bands. As shown in FIG.
