    • A device (50) capable of selectively altering its appearance can include a housing portion (64) of the device having at least one photochromic compound and an ultraviolet light source (60) forming a portion of the device for exposing the portion of the device having the photochromic compound to the ultraviolet light source. A reaction by the photochromic compound can provide or serve as a status indicator 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 camcorder, a vehicle, a toy, a personal hygiene device, a watch, a calculator, and a writing instrument for example. The device can be formed so that reactions by the photochromic compounds within the device are controlled solely by the ultraviolet light sources (54 and 60) within the device.
    • 能够选择性地改变其外观的装置(50)可以包括具有至少一个光致变色化合物的装置的壳体部分(64)和形成装置的一部分的紫外光源(60),用于暴露具有 该光致变色化合物到紫外光源。 光致变色化合物的反应可以提供或用作该装置的状态指示剂。 该设备可以是任何数量的设备,例如便携式通信设备,个人数字助理,膝上型计算机,照相机,GPS设备,打印机,摄像机,车辆,玩具,个人卫生设备,手表 ,计算器和书写工具。 该装置可以形成为使得装置内的光致变色化合物的反应仅由装置内的紫外光源(54和60)控制。
