The device comprises a sensing assembly for detecting a response of the TTI to a predetermined stimulus and generating measured data representative thereof, said measured data being indicative of the condition of the TTI, thereby enabling the determination of the remaining shelf life of the TTI and thereby any perishable good to which it is attached and calibrated.

Layered label structure with timer

The present invention relates to a thin, layered, variable label structure with built-in electronic functionality. The display and/or other functional elements in the structure may be formed by printing processes. The label structure includes a thin, layered structure with an active display, comprising a base layer and a cover layer of material and a display component situated between the base layer and the cover layer. The display is formed with a layer of electrochromic ink and a pair of spaced apart electrodes. The cover layer includes a window to allow for the layer of electrochromic ink to be visible through the cover layer. The label also is configured to respond to an actuating event by completing an electrical connection between a power source and the pair of spaced apart electrodes of the display component, thereby causing the display to change its appearance. The actuating event may include a variety of occurrences, such as: pressing a switch on the label, introducing a power source to activate the display, and a sensor sensing a condition near the label.

Intelligent label device and method

Briefly, an intelligent label is associated with a good, and includes one or more permanent and irreversible electrochromic indicators that are used to report the condition of that good at selected points in the movement or usage of that good. These electrochromic indicators provide immediate visual information regarding the status of the good without need to interrogate or communicate with the electronics or processor on the intelligent label. In this way, anyone in the shipping or use chain for the good, including the end user consumer, can quickly understand whether the product is meeting shipping and quality standards. If a product fails to meet shipping or quality standards, the particular point where the product failed can be quickly and easily identified, and information can be used to assure the consumer remains safe, while providing essential information for improving the shipping process. It will be understood that the label may take many forms, such as a tag attached to the good, integrated into the packaging for the good, integrated into the good itself, or may even be an information area on a prepaid card for example. The label may also include, for example, print information regarding the good, usage or shipping rules, or address and coded information.

Display device

一种显示装置包括：第一绝缘基板（10），在其一个表面上承载构成第一电极的第一导电材料（12）；构成第二电极的第二导电材料（16），其与第一导电材料以相对的关系设置并且与其隔开；以及电解质，提供第一和第二导电材料之间的传导通路。在使用该装置时，将电位差施加在第一和第二导电材料之间，使得在其中第一和第二材料直接相对的一个或多个区域中有选择地从第一基板完全去除第一材料，因此形成可检测的图像。由于第一材料已从第一基板的一个或多个区域完全去除，并且由于第一基板不导电，因此该过程是不可逆的并且因此导致了固定的显示。不同于比如LCD，这构成了不依赖于电力的永久的记录。在本发明的装置上产生的显示因此是不可逆的和永久的。
