摘要： A temperature sensing system 10 comprises an optical waveguide 102, a shape memory alloy (SMA) element 106a, and an interrogator 12. The SMA element 106a is deformable as a function of temperature and at least partially surrounds the optical waveguide 102. The interrogator 12 is configured to detect distributed temperature along the optical waveguide 102 using spectroscopy and to detect strain in the optical waveguide 102 induced by deformation of the SMA element 106a to identify local hot spots along the optical waveguide 102.

摘要： The present method refers to the development of attachments to be incorporated inside the product bulk, such as food products, for the effective continuous detection and recording of temperature changes that denote faulty maintenance conditions during the storage of the product, its transport and distribution.
Both detection and recording of specific temperature changes are effected with this method based on the change of shape of the so-called "Shape Memory Alloys" (SMA). The latter, change their shape in specific ways in response to temperature changes outside a predefined range, while when coated with other materials, such as plastic polymers or TiO 2 , they change their colour after their geometric state -e.g. contraction or dilation- has been transformed.
Their cost is very low compared with the products that their safe maintenance is detected and recorded and no external power source is required, so that they can be directly attached to the product, closely monitoring its actual life-long maintenance temperatures.摘要翻译： 本发明的方法是指附件产品批量内的被并入，：如食品产品的发展，对于有效的连续的检测和温度变化的记录产品，其运输和分配的储存期间没有表示有故障的维修条件。 的具体的温度变化二者检测和记录实现基于所谓的“形状记忆合金”（SMA）的形状变化此方法。 后者，更改其以特定的方式形状响应于预定义范围以外的温度变化，当与其它材料，彩色涂层而：如塑料聚合物或TiO 2，它们改变它们的颜色后它们的几何状态-e.g. 收缩或dilation-进行了改造。 其成本是非常低的比较的产品做检测其安全维护和记录，并且不需要外接电源，因此thatthey可以直接附着在产品上，密切关注其实际终身维护的温度。

摘要： Ce mécanisme indicateur est du type dans lequel le dépassement d'une température déterminée se traduit par une coloration irréversible ou la mise en route ou l'arrêt d'une machine. Selon l'invention, chaque coloration, mise en route ou arrêt est déclenchée à l'aide d'un élément (9,10) en un alliage à mémoire de forme. La coloration à une température déterminée peut être obtenue par le mélange d'un corps liquide à cette température avec au moins un colorant, le corps et le colorant associés à cette température sont placés chacun dans une chambre distincte respectivement (4, 5, 6) du boîtier (3) du dispositif, un obturateur (9,10) formé dans un alliage à mémoire de forme dont la température de transformation est sensiblement égale à la température déterminée ferme le passage (7, 8) faisant communiquer ces chambres respectivement (4, 5 et 5, 6).

摘要： A disinfection indicator mounted on medical equipment which is inserted into a channel for forceps and repeatedly used after thermal sterilization, includes a deformable portion, made of a shape memory alloy having a one-way shape memory effect, which is deformed plastically by an external force, from a shape indicating disinfection of the medical equipment to a predetermined original shape when the medical equipment is in use, and which is modified from the original shape to the shape indicating disinfection of the medical equipment when the medical equipment is heated to a temperature higher than a predetermined temperature.

摘要： A sheeting includes a layer of a shape-memory polymer material having a surface of microlenses, wherein each of the microlenses is associated with one of a plurality of images within the sheeting. The layer of the shape-memory polymer material is responsive to an external stimulus; e.g., temperature, solvent, or moisture; by transitioning from a first state in which an optical property of the microlenses has a first value to a second state in which the optical property of the microlenses has a second value. The microlenses have refractive surfaces that transmit light to positions within the sheeting to produce a composite image from the images formed within the sheeting when the layer of the shape-memory polymer material is in one of the first state and the second state. At least one of the images is a partially complete image, and each of the images is associated with a different one of the microlenses.

摘要： A temperature alert device to warn of imminent devitrification due to warming of a biological specimen that uses shape memory materials. The temperature induced phase transformation of shape memory materials causes a temperature responsive actuator to extend an alert rod upon warming as the specimen temperature approaches the devitrification temperature (e.g. -130°C). The temperature alert device is automatically reset upon immersion in liquid nitrogen.
