Method, apparatus, and computer program product are provided for determining a maximum temperature to which a perishable good or other temperature sensitive item was exposed. In some embodiments, a capacitance of a circuit provided on a substrate is measured. The circuit includes capacitor(s) each having first and second plates separated from each other by an ionic liquid (IL) in a solid state. The IL melts at a predetermined temperature and flows away from the first and second plates into a void. In some embodiments, the predetermined temperature at which the IL melts is different for each capacitor. For example, each capacitor in the circuit may employ a different N-alkyl bezothiazolium salt. A maximum temperature of exposure is determined based on the measured capacitance. In some embodiments, a decision of whether to discard the perishable good or other temperature sensitive item may be based on the determined maximum temperature.

Embodiments for assessing energy usage efficiency in a fluid transfer pumping system in a cloud computing environment by a processor. A rate of temperature decay may be determined over a selected time period using a temperature signal collected by one or more non-intrusive Internet of Things (IoT) sensors located at one or more selected positions of a piping network in the fluid transfer pumping system so as to determine energy efficiency in the fluid transfer pumping system associated with a heating service, a cooling service, or combination thereof.

The invention relates to a smart thermal insulation box, including thermally insulated layers with mitered edges forming a thermally insulated space, and said space surrounded by corrugated material.
