  • Publication number: 20190265571
    Abstract: Electrochromic window systems and components thereof are disclosed, more particularly systems where electrochromic devices are powered and/or controlled using photonic energy. In some instances, a laser is driven by a driver to deliver photonic power and/or control information into an optical fiber. The optical fiber carries the power and control information to a photovoltaic converter and a controller. The photovoltaic converter and controller may be included within an insulated glass unit (IGU). The photovoltaic converter converts the light energy into electrical energy used to power a transition in an optical state of an electrochromic layer or layers within the IGU. The controller may be used to control the power delivered to the electrochromic layer(s), such that a smooth transition occurs. In some embodiments, control information may be transmitted in an upstream manner to communicate information regarding, for example, the state of an electrochromic device.

  • Patent number: 10242788
    Abstract: The invention relates to anisotropic, reflective, magnetic flakes. In a liquid carrier and under influence of an external magnetic field, the flakes attract to one another side-by-side and form ribbons which provide higher reflectivity to a coating and may be used as a security feature for authentication of an object.

  • Patent number: 10173455
    Abstract: A printed image is disclosed wherein the image may be in the form of an array of magnetically aligned platelets or flakes that may by uniform in shape and size and wherein the flakes are arranged in a particularly manner to form optically illusive images useful as security devices, or useful in beam steering applications. In one embodiment of this invention printed array is disclosed a plurality of concentric rings of magnetically aligned platelets disposed upon a substrate in the form of a Fresnel structure, preferably a Fresnel reflector. Advantageously, since the magnetic field can be controlled with respect to strength and direction, one can easily design a field that will correct for spherical aberration that would otherwise be present in a typical Fresnel reflector. In other embodiments of the invention optically illusive images of funnels, domes and cones are printed.

  • Patent number: 9257059
    Abstract: A device includes a substrate and at least 1,000 flakes resting upon the substrate, each flake including a magnetic layer. The plurality of flakes are aligned so as to form a plurality of rings or curves, wherein within each ring or curve, flakes are tilted at a same angle with respect to the substrate and planes extending from surfaces of said flakes intersect with one another. The device provides a visible image of a single ring or curve when illuminated with a single light source, and three rings or curves are visible when three light sources illuminate the device. The device may be used as a printed light detector.

  • Patent number: 9097854
    Abstract: An optical device exhibiting a color shift upon rotation is disclosed. The optical device has a textured surface having a relief structure finer than a human eye resolution but large enough not to exhibit diffraction effects. The textured surface is coated with an interference thin film that exhibits a color shift with tilt. A uniform color seen at one angle of rotation changes to another uniform color when the optical device is rotated in its own plane. A method of manufacturing of such an optical device, as well as the use of the optical device as an optical security and authentication element, is also disclosed.

  • Patent number: 8726806
    Abstract: A printing apparatus includes a magnetic rotatable roller with a smooth even outer surface for aligning magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as bank notes. Magnetic flakes in the ink are aligned using magnetic portions of the roller, that can be formed by permanent magnets embedded in a non-magnetic roller body, or selectively magnetized portions of a flexible magnetic cover of the roller. In some embodiments, the roller is assembled for a plurality of interchangeable sections, which can include spinning magnets. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.

  • Patent number: 8287989
    Abstract: A security image is disclosed which is formed from flakes having a first color with flakes having a second different color mixed within a carrier uniformly. The flakes having the second color are magnetically orientable and the flakes having the first color are non-magnetic and do not align or orient in a magnetic field. By exposing at least a single coated region to a magnetic field that is substantially orthogonal to the substrate upon which the coating of flakes is coated, a visible region having the first color is provided as the magnetic flakes are upstanding and the non-magnetic flakes are lying flat upon the substrate. In another region where there is no field applied a visible region having third perceived color different from, however formed from the first color or the second color is seen.
