The invention relates to a device for the temperature monitoring of a cryopreserved biological sample, comprising a sample container (in particular a cryotube) having a holding space for holding a biological sample and comprising at least one chamber, the interior of which is not fluidically connected to the holding space and is filled only partially with an indicator substance, the melting temperature of which lies in a range of −20° C. to −140° C. In particular, the chamber can be formed by a container that is detachably or pivotably fastened to the sample container. Alternatively, the chamber is formed by a double-walled slide-on part or the holding space of the sample container is double-walled, wherein an intermediate space between the inner wall and the outer wall is partially filled with the indicator substance.

Disclosed is a method of determining subsurface temperatures of a surveyed region. The method comprises using a transmitter to transmit a pulsed electromagnetic signal into the ground; using a receiver to detect a return signal following interaction of said transmitted signal with features of the subsurface and determining one or more temperatures within the subsurface from the return signal. The temperature may be determined from a dielectric constant of a subsurface region, as determined from the received signal.

A system and method for rapidly determining ambient temperature in a fluid-analyte meter. The meter includes a housing defining an interior space and an area for receiving a fluid sample. A processor and a first temperature sensor are disposed within the interior space of said the housing. A second temperature sensor is disposed on the housing. One or more processors are configured to determine a first temperature value from temperature data received from the first temperature sensor. The processor(s) are also configured to apply a variable current to a temperature-adjustment source such that the second temperature sensor is adjusted to a predetermined steady-state temperature value different from the first temperature value. The processor(s) are further configured to determine an ambient temperature of an exterior space of the housing based on the applied variable current, pre-determined steady-state temperature, and received first temperature values.

A brake device applies a braking force to a vehicle by pressing a friction material against a rotor rotating integrally with a wheel. A temperature estimation method applied to the brake device includes: calculating an amount of absorbed energy absorbed by the rotor based on an amount of kinetic energy that the vehicle loses and an amount of potential energy that the vehicle loses during braking of the vehicle; and estimating a temperature of the rotor based on the amount of absorbed energy.
