Abstract
A micro-optic security device that employs one or more planar arrangements of stitched icons and that projects at any given viewing angle one or more synthetically magnified images, is provided. The synthetically magnified image(s) constitutes either a single or multipart image(s) that optionally changes to a different image(s) as the security device is tilted, or as the viewing angle changes.
Claims43
A micro-sized stitched icon, which comprises slices from one or more icon designs, wherein each slice is spaced slightly apart from, abuts, or slightly overlaps an adjacent slice(s).
A stitched icon, which comprises slices from one or more icon designs, wherein each slice is spaced slightly apart from, abuts, or slightly overlaps an adjacent slice(s), wherein the stitched icon is a micron-sized stitched icon.
A security device that comprises one or more arrangements of micro-sized stitched icons, each stitched icon comprising slices from one or more icon designs, wherein each slice is spaced slightly apart from, abuts, or slightly overlaps an adjacent slice(s).
A security device that comprises one or more arrangements of micro-sized stitched icons, each stitched icon comprising slices from one or more icon designs, wherein each slice is spaced slightly apart from, abuts, or slightly overlaps an adjacent slice(s), and further comprises one or more arrangements of microlenses, the arrangements of microlenses and stitched icons cooperating to form one or more synthetically magnified images.
A security document or label having at least one security device at least partially embedded therein and/or mounted thereon, wherein the at least one security device comprises one or more arrangements of micro-sized stitched icons, each stitched icon comprising slices from one or more icon designs, wherein each slice is spaced slightly apart from, abuts, or slightly overlaps an adjacent slice(s).
A security document or label having at least one security device at least partially embedded therein and/or mounted thereon, wherein the at least one security device comprises one or more arrangements of micro-sized stitched icons, each stitched icon comprising slices from one or more icon designs, wherein each slice is spaced slightly apart from, abuts, or slightly overlaps an adjacent slice(s), wherein the at least one security device is a micro-optic security device that further comprises one or more arrangements of microlenses, the arrangements of microlenses and stitched icons cooperating to form one or more synthetically magnified images.
A security device which comprises:
- (a) a substrate;
- (b) an array of micro-stitched icons positioned on or within a surface of the substrate, each stitched icon comprising slices from two or more icon designs, the stitched icons arranged in a plurality of mutually perpendicular columns and rows, wherein the icon designs or portions thereof embodied in the slices that make up each stitched icon transition either down each column or across each row;
- and
- (c) a corresponding array of microlenses, disposed substantially parallel to the array of stitched icons with focal points of at least some of the microlenses being substantially aligned with slices in the stitched icons,
- wherein the distance between the arrays is sufficient for the microlenses to form synthetically magnified images of the transitioning icon designs, and
- wherein the synthetically magnified images smoothly transition from one form to at least one other form as the device is tilted along its horizontal axis or as the device is tilted along its vertical axis.
A security device which comprises:
- (a) a substrate;
- (b) an angled array of similarly angled micro-stitched icons positioned on or within a surface of the substrate, each stitched icon comprising slices from two or more icon designs, the stitched icons arranged in a plurality of mutually perpendicular columns and rows, wherein the icon designs or portions thereof embodied in the slices that make up each stitched icon transition either down each column or across each row;
- and
- (c) a corresponding array of microlenses, disposed substantially parallel to the array of stitched icons with focal points of at least some of the microlenses being substantially aligned with slices in the stitched icons,
- wherein the distance between the arrays is sufficient for the microlenses to form synthetically magnified images of the transitioning icon designs, and
- wherein the synthetically magnified images smoothly transition from one form to at least one other form as the device is tilted along its horizontal axis and as the device is tilted along its vertical axis.
