20130189489 | MICRO-RELIEF STRUCTURES - The present invention provides a method of forming a relief pattern as part of a layered structure and comprising, forming a relief pattern on the surface of a layer of the said structure and subsequently forming a protective fixing layer on at least part of the said relief pattern and serving to protect the underlying relief pattern during any subsequent processing of the said structure, and thereby also provides for a layered structure, generally comprising a substrate having a relief pattern formed on a surface of the substrate and wherein at least a portion of the said relief has been provided with a protective fixing layer serving to retain the characteristics of the relief pattern during any subsequent processing of the structure such as, for example, when forming a laminate structure with the relief pattern provided therein. | 07-25-2013 |
20120314268 | PACKAGE AND METHOD OF FORMATION - The present invention provides for a device package comprising an element secured to a plastic body, the element having at least one opening into which material of the plastic body extends to at least assist with securing the element to the body. | 12-13-2012 |
20110310485 | OPTICAL DEVICE AND METHOD OF MANUFACTURE - The present invention provides for a diffractive structure comprising a plurality of grooves each formed by a plurality of two-dimensional scattering and/or diffractive groove elements, aligned in a manner serving to provide for at least one diffractive optical effect and further a surface display device comprising a plurality of regions wherein each region has a diffractive surface relief structure as defined above and wherein the gratings of one of said regions at an angle relative to the gratings of another of said regions. | 12-22-2011 |
20090153967 | OPTICAL SECURITY DEVICE OFFERING 2D IMAGE - The present invention provides for a diffractive element comprising a diffractive optical microstructure consisting of a modulated structure of a diffractive type which upon illumination by diffused ambient light creates a two-dimensional image to be viewed by an observer upon tilting or rotating the device or by varying lighting direction, wherein the diffractive modulated structure of the device consists of various generally parameterised special optical elements with specifically prescribed groove shapes, wherein each groove shape, position, centre(s), and line thickness, are described by functions describing those dependencies which are variables of the positional coordinate of the optical element. | 06-18-2009 |
20090091834 | METHOD OF CREATING A THREE-DIMENSIONAL IMAGE, A DIFFRACTIVE ELEMENT AND METHOD OF CREATING THE SAME - The invention discloses a diffractive device and a method of creating the same displaying a three-dimensional preferably achromatic image, especially imitating a real or an imaginary relief scene, a flat microrelief or otherwise modulated structure ( | 04-09-2009 |
