Latest Patent Applications

Graham Triggs-Ramm has filed several patent applications that showcase his inventive ideas. One of his latest applications is titled "Method of Applying a Pattern, and Security Device for an Article." This application discloses methods for applying patterns and security devices. In one arrangement, a receiving member with a layered structure is provided, which includes a layer of phase change material. This material can be thermally switched between multiple stable states with different refractive indices. An embossing member is stamped into the receiving member, heating a selected portion of the phase change material during the stamping process. This heating thermally switches the material, applying a pattern of varying refractive indices.

Another significant application is "Display Device and Projection Device." This disclosure relates to display devices and methods for displaying patterns. In this arrangement, a device comprises at least one display element with a layered structure. This structure includes a diffraction layer with a periodic structure designed to diffract visible light into a guided-mode resonance. Additionally, a phase change material layer is thermally switchable between two stable states with different refractive indices, allowing for effective coupling between the guided-mode resonance and the phase change material.

Conclusion

Graham Triggs-Ramm is an innovative inventor whose work at E Ink Corporation focuses on advanced display technologies. His latest patent applications reflect his commitment to developing new methods and devices in this field.
