Temperature locale sensors include an enclosure defining a sealed volume with a phase-change material therein at a known pressure. The phase-change material is formulated to exhibit a gas-to-solid phase change, without condensing to a liquid phase, at the known pressure and a targeted temperature, i.e., the material's “deposition temperature.” The phase-change material—while at least partially in gaseous form, either initially or after sublimation—is exposed to an environment with temperatures varying by location, including a maximum temperature above the phase-change material's deposition temperature and other temperatures at or below the deposition temperature. The gaseous phase-change material, in a location at the deposition temperature, solidifies from its gaseous phase to form solid grain deposits on a surface within the enclosure of the sensor. The solid deposits precisely identify the location of the specific, targeted deposition temperature.

The invention relates to a device for monitoring the temperature of a cryogenically preserved biological sample. The device (10) comprises a sample container (1) having a receptacle space (2) for accommodating a biological sample (6). The device further comprises at least one chamber (11), the interior (12) of which is not fluidically connected to the receptacle space, and which is at least partially filled with an indicator substance (7) having a boiling point or sublimation temperature in a range from −10° C. to −140° C. The chamber (11) further has at least one opening via which the indicator substance (7) can escape from the interior (12) of the chamber (11) upon exceeding its boiling point or sublimation point. The invention further relates to a method for monitoring the temperature of a cryogenically preserved biological sample.

A system for determining when an electrical contact or other component reaches a predetermined temperature. In operation, a trace material is dispersed into a surrounding environment (e.g., head space within a compartment above insulating oil), where the trace material is detected. A barrier may be ruptured or broken by temperature-induced gas pressure, or pierced by a spring-loaded member that is located within the same section that contains the trace material, and devices may be provided for moving the trace material through the foil barrier as the barrier is ruptured. The barrier may be opened solely by internal gas pressure. According to another embodiment, improved fail-safe operation may be achieved by providing a spring-loaded member and configuring the barrier to be ruptured by the pressure of the detectable gas material before the barrier is ruptured by the spring-loaded member.

An indication of an ambient temperature near food is received using an ambient temperature sensor of a food thermometer, and an indication of a food temperature at an interior portion of the food is received using one or more thermal sensors of the food thermometer. A rate at which the indication of the food temperature changes is determined, and the completion time is estimated based on at least the indication of the ambient temperature near the food and the rate at which the indication of the food temperature changes. In one aspect, a resting temperature rise is estimated based on the rate at which the indication of the food temperature changes and at least one of a food type, a thickness of the food, and an amount of time for the indication of the food temperature to increase by a temperature rise value during a period of cooking.
