20090243279Security device for security substrates - The invention relates to a security device for security substrates, such as paper, used for making security documents, such as bank notes, having anti-counterfeitable features. The security device comprising a carrier (10-01-2009
20110122499Optically variable devices - A security device comprises a substrate having an array of microlenses on one side and one or more corresponding arrays of microimages on the other side. The microimages are located at a distance from the microlenses substantially equal to the focal length of the microlenses. The substrate is sufficiently transparent to enable light to pass through the microlenses so as to reach the microimages. Each microimage is defined by an anti-reflection structure on the substrate formed by a periodic array of identical structural elements, light passing through a substrate and impinging on the microimages being reflected to a different extent than light which does not impinge on the microimages thereby rendering the microimages visible.05-26-2011

Patent application numberDescriptionPublished
20090108578Security devices for security substrates - The invention relates to a security device for security substrates, such as paper used for making security documents, such as banknotes, having anti-counterfeitable features. The invention therefore provides a security device comprising a carrier of at least partially light transmitting polymeric material. A carrier bears a plurality of first indicia which are easily visible to the human eye. The first indicia are defined by a plurality of smaller second indicia which are less visible to the human eye positioned relative to each other to enable the first indicia to be visualised.04-30-2009

20080231976Security Device Based on Customized Microprism Film - A security device comprises at least two regions, each region comprising a prismatic surface structure defining an array of substantially planar facets. Each region forms a reflector due to total internal reflection when viewed at least one first viewing angle and is transparent when viewed at least one second viewing angle. The said at least one first viewing angle of one region is different from the at least one first viewing angle of the other region. Furthermore, a security device comprising an asymmetrical or truncated prismatic surface structure is located in a transparent area of an article.09-25-2008

20090325443Fabricating symmetric and asymmetric shapes with off-axis reinforcement from symmetric preforms - A device for obtaining off-axis reinforcement of a woven object. The device is made up of a fixed mandrel and a rotating mandrel. The rotating mandrel is connected to the fixed mandrel by a shaft that rotates through the middle of the fixed mandrel. The shaft allows the rotating mandrel to move up and down in relation to the fixed mandrel. A portion of the woven object can be clamped to the fixed mandrel while a second portion of the woven object can be clamped to the rotating mandrel. When rotated, the rotating mandrel causes the warp fibers in the woven object to twist off the 0° direction while fill or hoop fibers remain substantially parallel to the 90° direction.12-31-2009
