    • A timer indicator or chronograph is described. The chronograph functions according to chromatographic principles to develop a perceptible visual image or pattern on an indicator panel or display area, which serves as a means to monitor the relative amount of time that elapses. The chronograph includes a self-contained reservoir for an activating agent, which once activated creates a mobile front that traverses the indicator panel substrate from the reservoir to a distal end at a predetermined rate. The chronograph may be used as a stand-alone device or may be incorporated as part of various articles or products, for instance, as either a training aid or as a dryness indicator. Methods for using and making the chronograph are also described.
    • 描述了定时器指示器或计时码表。 计时码表根据色谱原理起作用,以在显示面板或显示区域上形成一个可察觉的视觉图像或图案,这是监测经过的相对时间量的一种手段。 计时码表包括用于激活剂的独立储存器,其一旦被激活就产生以预定速率从储存器穿过指示器面板基底到远端的移动前部。 计时码表可以用作独立设备,也可以作为各种物品或产品的一部分来使用,例如作为训练助剂或干燥指示剂。 还描述了使用和制作计时码表的方法。
