Abstract: A method of making an optical article having a gradient tint and a gradient polarization. The method includes contacting one or more dye compositions including at least one of a dichroic dye, a photochromic-dichroic dye, or any combination thereof, with an optical element having a continuous coating including at least one alignment zone. At least a portion of the dye composition diffuses into the coating at a predetermined concentration gradient along at least a portion of the coating.

Abstract: A device for photoexcitation of a photo-responsive material, such as a photochromic material, includes a pen-type housing having a UV lamp at one end and a visible light lamp at the other end. The device includes a microcontroller, a power supply, and an input device such as button, microphone, temperature sensor, or accelerometer. The beam width of the lamps can be adjusted by a lens adjacent to the respective lamps. The device is designed to photoexcite the photo-responsive material into various states depending on the type and wavelength of light emitted from the device. The device enables writing and erasing on a substrate, such as human skin, that contains or is embedded with the photo-responsive material, by exposing the material to light emitted from the device.

Abstract: Pervasive and interactive displays promise to present digital content seamlessly throughout a room. However, traditional display technologies do not scale to room-wide applications due to high per-unit-area costs and the need for constant wired power and data infrastructure. This disclosure proposes the use of photochromic paint as a display medium. Applying the paint to any surface or object creates ultra-low-cost displays, which can change color when exposed to specific wavelengths of light. New paint formulations are developed that enable wide area application of photochromic material. Along with a specially modified wide-area laser projector and depth camera that can draw custom images and create on-demand, room-wide user interfaces on photochromic enabled surfaces. System parameters such as light intensity, material activation time, and user readability are examined to optimize the display. Results show that images and user interfaces can last up to 16 minutes and can be updated indefinitely.

Abstract: A photochromic polyurethane laminate wherein the photochromic polyurethane layer of the laminate has been crosslinked with an isocyanate-active prepolymer using a crosslinking agent. The crosslinking agent is formulated to have at least three functional groups that are reactive with functional groups of the polyurethane or of the isocyanate-active prepolymer. A method of making the photochromic polyurethane laminate includes steps of causing the crosslinking.
