Abstract:

A security device () includes arrangements of image icons (), arrangements of refractive image icon focusing elements () and a sealing layer (), wherein the arrangements of refractive image icon focusing elements is disposed above the arrangements of image icons such that a portion of the arrangements of refractive image icon focusing elements projects a synthetic image, such that the arrangements of refractive image icon focusing elements contact the sealing layer along a non-planar boundary. Further, at least one of the arrangements of refractive image icon focusing elements and the sealing layer comprises an organic resin mixture having a first refractive index, and at least one of the arrangements of refractive image icon focusing elements and the sealing layer comprises a low-refractive index material, the low-refractive index material having a second refractive index.

Abstract:

An electro-optic media includes either a plurality of microcapsules in a binder, a polymeric sheet containing sealed microcells, or droplets in a continuous polymeric phase. Each of the microcapsules, microcells, or droplets contain a dispersion that includes a plurality of charged composite particles and a suspending fluid, and the charged particles move through the suspending fluid under the influence of an electric field. The composite particles include one or more types of pigment particles that are at least partially coated with a polymeric material. Each of the binder, polymeric sheet, continuous polymeric phase, the charged composite particles, and the suspending fluid have an index of refraction, and a difference between the index of refraction of the composite particles and at least one of the binder, polymeric sheet, continuous polymeric phase, and solvent is less than or equal to 0.05 at 550 nm.

Abstract:

A variable transmission medium comprises a fluid and a plurality of nanoparticles dispersed in the fluid, wherein addition of acid to the fluid causes the nanoparticles to flocculate and form aggregates of particles that scatter light. The nanoparticles may comprise at least one metal oxide, such as titanium dioxide, zinc oxide or zirconium dioxide. The fluid may have a dielectric constant less than about 10. The medium may be used in, for example, privacy glass for a conference room.
