Method for storing and / or transporting temperature-sensitive materials. In one embodiment, the method involves predicting whether a given passive thermal shipping system will maintain a payload within a desired temperature range over its entire transport / delivery route. To this end, thermal capacitance data is compiled for the shipping system at a plurality of temperatures spanning a broad range of potential ambient temperatures to which the shipping system may be exposed. In addition, forecasted ambient temperature data is obtained for a plurality of time intervals spanning the transport / delivery route. An effective ambient temperature, based on the forecasted ambient temperature, as well as rolling and cumulative averages, is then determined at each of the various time intervals. Using the effective ambient temperature, the thermal capacitance is determined from the compiled data and is compared to the cumulative absorbed energy. The shipping system fails when the cumulative absorbed energy exceeds the thermal capacitance.

This application discloses a tactile sensor and its fabrication method. The tactile sensor includes a tactile membrane, an optical window, a cavity, a deformation structure, and a capacitor structure. The cavity is enclosed by a cavity wall and two opposing openings at both ends. The two openings respectively house the tactile membrane and the optical window. The deformation structure is located within the cavity and is used to absorb energy from an external light source. Under photothermal action, it deforms, thereby displacing the tactile membrane to generate tactile stimulation that can act on a target object. The capacitor structure converts the tactile stimulation into an electrical signal for tactile information acquisition. This application utilizes the deformation structure to deform within a certain temperature range, thereby displacing the tactile membrane and converting light energy into tactile output. This avoids the dependence of traditional light-driven tactile devices on closed air cavities, gas expansion, and suspended light-absorbing sheets, improving the structural stability and driving efficiency of the tactile sensor and increasing its environmental adaptability.

Therefore, the controller can judge whether pollutants exist on the surface of the protection lens or not according to the temperature distribution of the surface of the lens.
