2340 results about "Ornaments" patented technology

Ornaments are traits that are used to attract mates based on physical attractiveness. These traits may help show good genes that potential mates may find desirable. Although these ornaments are usually the main strategy in order to procure a mate, they come with the cost of making the individuals more susceptible to being tracked by predators. The most notable form of ornaments comes in the ornate plumage that the peacock has in order to attract peahens; the brighter and bigger the feathers, the better chance of finding a mate.

Authentication of documents and articles by moiré patterns

The present invention relies on the moiré patterns generated when superposing a base layer made of base band patterns and a revealing line grating (revealing layer). The produced moiré patterns comprise an enlargement and a transformation of the individual patterns located within the base bands. Base bands and revealing line gratings may be rectilinear or curvilinear. When translating or rotating the revealing line grating on top of the base layer, the produced moiré patterns evolve smoothly, i.e. they may be smoothly shifted, sheared, and possibly be subject to further transformations. Base band patterns may incorporate any combination of shapes, intensities and colors, such as letter, digits, text, symbols, ornaments, logos, country emblems, etc. . . . . They therefore offer great possibilities for creating security documents and valuable articles taking advantage of the higher imaging capabilities of original imaging and printing systems, compared with the possibilities of the reproduction systems available to potential counterfeiters. Since the revealing line grating reflects a relatively high percentage of the incident light, the moiré patterns are easily apparent in reflective mode and under normal illumination conditions. They may be used for the authentication of any kinds of documents (banknotes, identity documents, checks, diploma, travel documents, tickets) and valuable articles (optical disks, CDs, DVDs, CD-ROMs, packages for medical drugs, bottles, articles with affixed labels).

Authentication of secure items by shape level lines

The disclosed method and system may be used for creating advanced protection means for various categories of documents (e.g. bank notes, identity documents, certificates, checks, diploma, travel documents, tickets) and valuable products (e.g optical disks, CDs, DVDs, CD-ROMs, prescription drugs, products with affixed labels, watches) hereinafter called “secure items”. Secure items are authenticated by shape level lines. The shape level lines become apparent when superposing a base layer comprising sets of lines and a revealing layer comprising a line grating. One of the two layers is a modified layer which embeds a shape elevation profile generated from an initial, preferably bilevel, motif shape image (e.g. typographic characters, words of text, symbols, logo, ornament). In the case of an authentic document, the outline of the revealed shape level lines are visual offset lines of the boundaries of the initial bilevel motif shape image. In addition, the intensities, respectively colors of the revealed shape level lines are the same as the intensities, respectively colors of the lines forming the base layer sets of lines. By modifying the relative superposition phase of the revealing layer on top of the base layer or vice-versa (e.g. by a translation or a rotation), one may observe shape level lines moving dynamically between the initial bilevel motif shape boundaries and shape foreground centers, respectively background centers, thereby growing and shrinking. In the case that these characteristic features are present, the secure item is accepted as authentic. Otherwise the item is rejected as suspect. Pairs of base and revealing layers may be individualized by applying to both the base and the revealing layer a geometric transformation. Thanks to the availability of a large number of geometric transformations and transformation parameters, one may create documents having their own individualized document protection. The invention also proposes a computing and delivery system operable for delivering base and revealing layers according to security document or valuable product information content. The system may automatically generate upon request an individually protected secure item and its corresponding authentication means.

Method for preparing photonic crystals through 3D (Three-Dimensional) printing

ActiveCN103802315ADiversified structure and morphologyGeneralization of structural morphologyPhotonicsEngineering
The invention discloses a method for preparing photonic crystals through 3D (Three-Dimensional) printing. The method comprises the following steps of preparing macromolecule raw materials for 3D printing by using monodisperse colloidal particles, layering a three-dimensional solid model of photonic crystals into a plurality of two-dimensional patterns, printing the two-dimensional patterns layer by layer in sequence on a substrate and curing layer by layer to prepare three-dimensional photonic crystals which having high dielectric ratios or are suitable for network topology structures. Compared with a current preparation method of the photonic crystals, the method is quick and convenient, lo in investment costs of devices, simple in process, energy-saving and environmentally friendly and short in consumed time, and three-dimensional structure shapes of the prepared photonic crystals are diversified and extensive. The method is an ideal manner of preparing special-purpose photonic crystals in the future. The method is capable of realizing batch production; the prepared photonic crystals can be widely applicable to the scientific research and life of optical devices, tissue culture frames, super lyophobic liquid surface, anti-counterfeiting marks and ornaments, so that the photonic crystals are wide in market prospects.
