摘要： A label for a component is provided with a continuous color tone background at least in segments of the label that can be detected as to a configuration using selected colored light sources which reflect from the different color tones of the label. A sensor can be used for discriminating between the reflection patterns from the light sources. A continuous color tone on the label changing smoothly from one color to others is applied to make a uniform shading from one color at one end of the label to another color at a second end, with various colors between the two ends. As an added feature, a number of black appearing strips forming a bar code can be provided on the label, with some of the strips reflecting infrared light and others not reflecting infrared light, so an infrared detector can be utilized for determining the pattern of the bar code for further identification of the labeled component. The bar code pattern will not be identifiable with the naked eye.
摘要翻译：至少在标签的片段中，组件的标签被提供有连续的色调背景，可以使用从标签的不同色调反射的选定的彩色光源来检测配置。可以使用传感器来区分来自光源的反射图案。应用标签上的连续色调从一种颜色平滑地变化到其他颜色，以使标签一端的一种颜色的均匀阴影在第二端处具有另一种颜色，两端之间具有各种颜色。作为附加功能，可以在标签上提供形成条形码的黑色条纹条，其中一些条带反射红外光，而其他条不反射红外光，因此红外检测器可用于确定用于进一步识别标记成分的条形码。条形码图案将无法用肉眼识别。
