DETAILED DESCRIPTION OF THE INVENTION

[0068] The present application relates to a camouflage pattern, characterized in that it comprises two superimposed designs, wherein the first design is a camouflage print comprising between 2 and 15 colors, of different tone or shade, in which there is a combination of alternating light and dark colors, and the second design placed over the first, which comprises a series of diagonal wave-like lines (2), which may be oriented in the same direction or may lie in opposite directions, intersecting in order to form a mesh, forming rhombi (3).

[0069] Said diagonal wave-like lines are sinusoidal lines that, when the print of the first design is intersected, generate a series of small, irregular sections, the frequency of which in nature is high, and therefore the human eye perceives them as normal and overlooks them because it considers them to be part of the surroundings.

[0070] In an alternative of the invention, the camouflage print comprises between 3 and 6 colors or tones, which are combined to create a micropattern (4) repeated along the pattern of the present invention.

[0071] In a preferred embodiment, the predominant color in the pattern of the first print is the lightest color or the second lightest color. It is preferable for said predominant color to be present in a proportion of from 30% to 60% of the total of the pattern.

[0072] Said first design comprises a print selected from the group comprising pixelated, blotch, band, brushstroke or strait camouflage. Preferably, the first design comprises a pixelated print in which the wave-like lines intersect each pixel at least once.

[0073] The second design, which consists of diagonal wave-like lines distributed along the pattern, where the distance between said diagonal wave-like lines may be the same along the pattern. In an alternative of the invention, the distance between the diagonal wave-like lines may vary along the pattern, said distance being smaller in certain areas of the pattern and greater in others.

[0074] Preferably, the ratio between the distance between the wave-like lines of the second design and the dimension of the side of the pixels forming part of the first design are in a proportion of between 0.1 and 2. The best option being those designs in which said proportion is equal to 1, i.e. the distance between the wave-like lines is equal to the dimension of the side of the pixels.

[0075] Complementing the aforesaid, given that the wave-like lines of the second design are sinusoidal, they form crests. Preferably, the distance between the crests of the waves of the wave-like lines of the second design is the same. However, also part of the present invention is the design in which the distance between crests of the wave-like line varies along the pattern.

[0076] Another important aspect of the present invention is the color of the wave-like lines forming the second pattern. The diagonal wave-like lines have to be in the same color as one of the colors of the first design in order to reduce the contrast of the pattern relative to its surroundings.

[0077] Preferably, the lines are in the same color as one of the colors of the first design, and better still said lines are in the most predominant color in the first design, this being in order to generate a greater reflectance of the light spectrum and to create a three-dimensional effect in the design since upon placing the mesh design on the fragments of the same color in the first design the lines of the mesh are lost, which causes the segments in the same color as the mesh to stand out. This information is processed by the human brain, giving an impression of depth.

[0078] In color theory, a tint is a mixture of a color with white, which reduces darkness, while a shade is a mixture with black, which increases darkness. Both processes affect the resulting color mixture's relative lightness. A tone is produced either by mixing a color with grey, or by both tinting and shading. Mixing a color with any neutral color (including black, gray, and white) reduces the chroma, or colorfulness, while the hue (the relative mixture of red, yellow, green, etc. depending on the colorspace) remains unchanged.

[0079] While pure color can be used, it is preferable that the chosen color's tint, tone and shades are used.

[0080] In art it is common to darken a paint color by adding black paintproducing colors called shadesor to lighten a color by adding whiteproducing colors called tints. Colors can also shift in their hues. For instance, darkening a color by adding black can cause colors such as yellows, reds and oranges, to shift toward the greenish or bluish part of the spectrum. Lightening a color by adding white can cause a shift towards blue when mixed with reds and oranges. See Abney effect, which describes the perceived hue shift that occurs when white light is added to a monochromatic light source. Sir Abney demonstrated that the cause of the apparent change in hue was the red light and green light that comprise this light source, and the blue light component of white light had no contribution to the Abney effect.

[0081] Another practice when darkening a color is to use its opposite, or complementary, color (e.g. violet-purple added to yellowish-green) in order to neutralize it without a shift in hue, and darken it if the additive color is darker than the parent color. When lightening a color this hue shift can be corrected with the addition of a small amount of an adjacent color to bring the hue of the mixture back in line with the parent color (e.g. adding a small amount of orange to a mixture of red and white will correct the tendency of this mixture to shift slightly towards the blue end of the spectrum).

[0082] In one embodiment, the colors black, brown, green, khaki and gray are used. A combination of tints and shades of these colors are used to make up the first design having a print being pixelated, blotch, band, brushstroke or strait camouflage. One of the colors used in the first design is applied and used for the second design, which consists of diagonal wave-like lines distributed along the pattern, provided that the color is not black in this particular embodiment. For example, gray is used in the second design.

[0083] According to the invention, neutral and near neutral colors are selected. These are, for example, earth tones such as black, brown, green, tan, khaki and gray. Neutral colors, are muted and flat in an emulation of natural colors and can be created by mixing two complementary colors or combining a pure color with white, black, or gray. Pure-neutral colors include black, white, and all grays, while near-neutral hues include browns, tan, and darker colors.

[0084] In another embodiment, the colors black, green, khaki and gray are used. A combination of tints and shades of these colors are used to make up the first design. One of the colors used in the first design is applied and used for the second design, wherein the color is not black. For example, gray is used in the second design.

[0085] In a further embodiment, the colors black, brown, green and khaki are used. A combination of tints and shades of these colors are used to make up the first design. For example, black, brown, dark green, khaki, light khaki and light green are used to make up the first design. One of the colors used in the first design is applied and used for the second design, wherein the color is not black. For example, light khaki is used in the second design.

[0086] In another embodiment, the colors black, brown, green and khaki are used. A combination of tints and shades of these colors are used to make up the first design. For example, black, brown, three different shades of green and a light khaki are used. One of the colors used in the first design is applied and used for the second design, wherein the color is not black. For example, light khaki is used in the second design.

[0087] In yet another embodiment, the colors black, brown, green and khaki are used. A combination of tints and shades of these colors are used to make up the first design. For example, black, two different shades of brown, two different shades of green and khaki are used. One of the colors used in the first design is applied and used for the second design, wherein the color is not black. For example, khaki is used in the second design.

[0088] In a further embodiment, black and gray are used. A combination of black and different tones of gray are used to make up the first design. The lightest tone of gray used in the first design is applied and used in the second design.

[0089] In addition to that which is set forth in the preceding paragraph, the wave-like lines conceal the edges of the shapes to which the pattern is applied, which compromises visual acuity, preventing outlines and shapes from being defined and thereby reducing the probability that the object covered with the pattern will be detected and identified, which ultimately leads to an increase in the survival rate of military personnel in countries in conflict.

EXAMPLES

[0090] With a view to demonstrating the effects achieved with the camouflage pattern of the present invention, a series of field studies were performed in which a group of persons were clothed in uniforms of which the fabric incorporates the camouflage pattern of the present invention and a second group of persons wore uniforms using clothing that did not have the superimposed mesh design.

[0091] To establish perception as to the level of detection and identification of the persons making up the above-defined groups, a group of 50 observers underwent the test of determining the location of the uniformed personnel, in photographs and in the field, in order to ascertain which uniform afforded greater camouflage.

[0092] Within this context, FIG. 2 shows a group (A) composed of four persons wearing the uniform with the pattern of the invention and a group (B) of four persons wearing a pixelated uniform lacking wave-like lines and having a different pixelated pattern. Of the observers questioned, 90% took the view that the pattern of the invention was less detectable, attracted less attention, and better resembled the surroundings.

[0093] When the group of observers was shown the photograph of FIG. 3, it was found that 80% of them perceived the color of the uniform in the same way as that of the structure alongside which the person using the pattern of the invention was located. Upon approaching said person, it was possible to establish that that assertion was incorrect since the uniform is gray and the greenish tones are the result of reflectance of the light spectrum on the pattern claimed herein.

[0094] FIG. 4 shows how reflectance of the light effect on the surface of the aircraft is in turn reflected by the camouflage pattern, causing a resemblance that prevents the wearer of the pattern being detected at a distance of 150 meters.

[0095] When the tests were carried out in different terrains and environments, it was found that despite using a color that was infrequent in nature, such as different tones of gray, good camouflage was successfully achieved independently of whether the space where the user wearing the uniform with the pattern was located was jungle (FIGS. 5 and 6), dry woodland (FIGS. 7 and 8) and savannah (FIG. 9), and in all cases the observers involved in the experiment had difficulty in terms of detecting and especially in terms of identifying the person wearing the uniform with the pattern of the present invention irrespective of the terrain in which the photograph was taken or the test was carried out.

[0096] By contrasting the level of camouflage between two patterns evaluated in the daylight test, it was found that 90% of those questioned saw the user (B) of the pattern without lines more easily than the user (A) of the pattern of the present invention.

[0097] Lastly, the two groups of users underwent detection using night-vision devices. FIG. 10 shows a user (B) of the camouflage without wave-like lines resting on the body of the user (A) of the camouflage pattern of the invention, 95% of observers taking the view that the body of the user (A) was a rock on which the user (B), who was easily detectable, was resting.

[0098] Given the results of the tests carried out, it is obvious that there is a reduction in the level of perception, detection and identification of the user of the pattern of the present application. This demonstrates the existence of an unexpected effect, since the inclusion of the diagonal lines of the second design forming the camouflage pattern of the invention enhances the level of camouflage of the user independently of the terrain and the environment in which said user is located.

[0108] In an illustrative embodiment, a camouflage pattern is formed based on first and second sets of non-intersecting curves defined by the polynomials described below. The first set of non-intersecting curves includes a plurality of curves defined by the following polynomials L1, L2, L3, and L4:

[0109] (1) L1(x)=1.0836207177069 x.sup.2+1.921228745901 x+0.5724094221115

[0112] (4) L4(x)=0.7939941438544 x.sup.31.1858399917424 x.sup.2+2.2388931265054 x0.6140668972257

[0113] L(1) and L(2) are polynomials of the second degree. L(3) and L(4) are polynomials of the third degree.

[0114] The second set of non-intersecting curves includes a plurality of curves defined by the following polynomials L5, L6, L7, and L8:

[0115] (5) L5(x)=0.302499107406 x.sup.22.2942684500755 x+0.6722748559549

[0116] (6) L6(x)=0.795648432102 x.sup.3+1.2617498853453 x.sup.22.7101461651996 x+1.4462384418432

[0117] (7) L7(x)=0.5738513358302 x.sup.3+1.9119887350931 x.sup.24.1031200242697 x+2.6729425536722

[0118] (8) L8(x)=4.7411319472502 x.sup.2+6.4893735173258 x1.1571743676205

[0119] L(5) and L(8) are polynomials of the second degree. L(6) and L(7) are polynomials of the third degree.

[0120] FIG. 12 shows a graph of the first set of non-intersecting curves defined by polynomials L(1)-L(4) and the second set of non-intersecting curves defined by polynomials L(5)-L(8) in accordance with an embodiment. Each of the first polynomials L(1)-L(4) intersects each of the second polynomials L(5)-L(8). The first and second sets of curves form a pattern that may be used to create a camouflage pattern.

[0121] The intersecting curves define a plurality of shapes including shapes 1225. Each shape 1225 has a first side formed from a first curved line, a second side formed from a second curved line, a third side formed from a third curved line, and a fourth side formed from a fourth curved line.

[0122] For example, a camouflage pattern including the pattern illustrated in FIG. 12 may be formed on a selected fabric to create a camouflage uniform. The camouflage may be formed of any suitable material, such as, for example, cotton, polyester, wool, etc. The uniform may be a 50% cotton, 50% nylon composition. Other materials may be used. Other material ratios may be used.

[0123] In accordance with an embodiment, a portion of a pattern formed by first and second sets of non-intersecting curves is defined, and the portion is copied and repeated in a repetitive pattern to create a larger pattern. The portion may be copied to form tiles, and the tiles may be placed in a repeating pattern such that the corners and edges of a first tile are fully adjacent, or may be placed in a staggered pattern such that each tile is shifted a predetermined distance relative to an adjacent tile.

[0124] For example, referring to FIG. 12, a portion (or tile) 1275 is defined in the region 0<x<1 and 0<y<1. Portion 1275 may be repeated and arranged as adjacent tiles to form a larger pattern 1340.

[0125] FIG. 13 shows a pattern created by repeating portion 1275 of graph 1240 in accordance with an embodiment. Pattern 1340 includes a plurality of tiles 1312, 1314, 1316, 1318. Each tile 1312, 1314, 1316, 1318 is a copy of portion 1274 of graph 1240. The pattern 1340 includes a first row containing tiles 1312 and 1314 and a second row containing tiles 1316 and 1318. In this example, the tiles in the second row are shifted by a distance d relative to the tiles in the first row. For example, tile 1318 is adjacent to tile 1314, but is shifted relative to tile 1314 by the distance d. While FIG. 13 shows only four tiles, in other embodiments, a repeating pattern may include more than four tiles. In other embodiments, tiles may be shifted by different distances, or may not be shifted, relative to adjacent tiles.

[0126] In accordance with an embodiment, a camouflage design may be created based on pattern 1340 of FIG. 13.

[0127] In order to create a larger pattern from a plurality of tiles, it is not necessary that the curves at the edges of each tile match or join with curves at the edges of adjacent tiles. In some embodiments, the curves at an edge of a first tile join precisely with curves at the edge of an adjacent tile. In other embodiments, the curves at an edge of a first tile do not join precisely with curves at the edge of an adjacent tile.

[0128] In accordance with another embodiment, for each polynomial among a first plurality of polynomials, a respective first plurality of first points associated with the corresponding curve are selected, and for each polynomial among a second plurality of second polynomials, a respective second plurality of second points associated with the corresponding curve is selected. For each polynomial, not all points are selected. A first plurality of non-intersecting curves is generated based on the first pluralities of first points, and a second plurality of non-intersecting curves is generated based on the second pluralities of second points. Because a limited number of points from each polynomial were used, the first plurality of non-intersecting curves and the second plurality of non-intersecting curves may represent only selected portions of the corresponding polynomials, and may differ from the corresponding polynomials.

[0129] FIG. 14 shows a first plurality of first points selected from a first plurality of first non-intersecting curves in accordance with an embodiment. FIG. 15 shows a second plurality of second points selected from a second plurality of second non-intersecting curves in accordance with an embodiment.
