917 results about "Camouflage" patented technology

Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis). Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores.

Camouflage U.S. Marine Corps combat utility uniform: pattern, fabric, and design

A camouflage system to be used for both military uniforms and equipment. The system includes specialized means of printing the camouflage system unto fabric. The system can also be used for civilian applications, particularly with sportsman hunters. The system provides camouflage in both the human visible light range and the infrared. The system depends on the use of a macro-pattern resulting from a repeat of a micro-pattern. When applied to fabric, a polyamide-cotton fiber blend has a macro pattern resulting from a repeat of a micro pattern printed on at least one surface. The coloring system used comprises at least four colorings from dyes that in combination produce a percent reflectance value comparable to the negative space of the surroundings near the camouflaged subject. The system functions by a macro pattern being disruptive of the shape of the subject and a micro pattern comprising sharp edge units of a size capable of blending the subject into the background. The relative lightness values and percentages of total pattern are sufficient to produce a percent reflectance of acceptable colors, wet or dry in terms of lightness values compared to current military four-color camouflage. On fabric, the results are achieved by printing A macro pattern that disrupts the sensed shape and a micro pattern with a repeat size that produces the macro pattern. The reflectance of the material is comparable to the negative space surrounding a subject so the subject does not appear too dark or too light (out of place). The variation in the lightness between wet and dry is not greater than 17-28%, achieved during the printing process.
