Application of composite functional materials to products fotocromu00e1tico

摘要

"Application materials for functional compound fotocromu00e1tico products.A device (50) capable of selectively altering their appearance may include a part of the frame (64) of the device having at least a compound fotocromu00e1tico and an ultraviolet light source (60).To form a part of the device for exposure of the device having the compound fotocromu00e1tico the ultraviolet light source.A reaction by the compound fotocromu00e1tico can provide or serve as an indicator of the situation for the device.The device can be any number of devices such as a portable communication device, a personal digital assistant, a laptop computer, a camera, a GPS device.A printer, a portable video camera (camcorder), a vehicle, a toy, a device for personal hygiene, a watch, a calculator, and a writing instrument, for example.The device can be formed so that reactions by the compound fotocromu00e1tico inside the device are controlled solely by the sources of ultraviolet light (54, 60) within the device.
