Abstract: A timing device comprises a sensing material and/or a component which is sensitive to the presence of an environmental attribute. The environmental attribute drives and speeds up or slows the timing device as the concentration of the attribute increases or decreases, respectively. Alternatively, the timing device is activated upon sensing the presence of the environmental attribute and indicates a total passage of time from exposure/activation of the timing device. Particularly, sensing materials of varying types are able to be used to indicate exposure to a variety of substances. For example, in some embodiments, the timing device comprises a sensing material which is sensitive to the presence of ultraviolet radiation. Alternatively, the sensing material is sensitive to other variables such as x-ray radiation and nuclear radiation. In further embodiments, the sensing material is sensitive to biological or physical contamination.

Abstract: An electro-optic display is produced using a sub-assembly comprising a front sheet, an electro-optic medium; and an adhesive layer. An aperture is formed through the adhesive layer where the adhesive layer is not covered by the electro-optic medium, and the sub-assembly is adhered to a backplane having a co-operating member with the aperture engaged with a co-operating member, thus locating the sub-assembly relative to the backplane. In another form of electro-optic display, a chip extends through an aperture in the electro-optic medium and adhesive layer. In a third form, the aforementioned sub-assembly is secured to a backplane and then a cut is made through both backplane and sub-assembly to provide an aligned edge.
