摘要： A shock indicator is described comprising (A) a base having a first side and a second side; (B) an indicator associated with the first side of the base, the indicator comprising a plurality of indicator subparts, the subparts comprising solid material arranged (i) in a first configuration when the shock indicator is in a first state prior to a shock event, and (ii) in a second configuration when the shock indicator is in a second state following a shock event; and (C) means associated with the second side of the base for attachment of the shock indicator to a surface. A method of manufacture is also provided.

摘要： A selectively activated time-temperature integrating device for providing a visually observable indication of cumulative thermal exposure, in which a viscoelastic material migrates into a diffusely light-reflective porous matrix at a rate which varies with temperature to progressively change the light transmissivity of the porous matrix and thereby provide the visually observable indication. The viscoelastic material can comprise a pressure sensitive adhesive. The visually observable indication can comprise latent indicia which initially are not visible and become visible, obscurable indicia which initially are visible and become obscured, or a combination of both. Various actuating means for selectively switching the indicator from an unactivated state to an activated state are described. Also disclosed are a method for providing a visually observable indication of cumulative thermal exposure and a method for providing a time and temperature integrating device for providing a visually observable indication of cumulative thermal exposure of an object.
摘要翻译：一种选择性激活的时间 - 温度积分装置，用于提供累积热暴露的视觉上可观察的指示，其中粘弹性材料以随温度变化的速率迁移到漫反射多孔基质中，以逐渐改变多孔基质的光透射率从而提供视觉可见的指示。粘弹性材料可以包括压敏粘合剂。视觉上可观察的指示可以包括最初不可见且变得可见的潜在标记，其最初是可见的并且变得模糊的可遮盖的标记，或两者的组合。描述了用于将指示器从未激活状态切换到激活状态的各种致动装置。还公开了一种用于提供可视可见的累积热暴露指示的方法，以及用于提供时间和温度积分装置的方法，用于提供物体的累积热暴露的视觉上可观察的指示。
