Disclosed herein are a refrigerator of sensing a degree of rancidity of fermented liquor to transmit state information of the fermented liquor to a remote user, and a method of controlling the refrigerator. The refrigerator may include a storage space configured to store fermented liquor; a cooling unit configured to cool inside air of the storage space; a rancidity sensor configured to sense a degree of rancidity of the fermented liquor; and a communication unit configured to transmit state information of the fermented liquor created based on the degree of rancidity to a predetermined external device.

The present disclosure provides a temperature control system of a rice paddy methane flux collecting device, which comprises: a chamber body having a collecting space in which a certain number of rice grains are located; a chamber door configured to open and close an upper side of the collecting space; a collecting unit configured to collect a sample gas in the collecting space; a heating unit and a cooling unit configured to increase or decrease the temperature in the collecting space; a circulation unit for circulating the gas in the collecting space; a ventilation unit configured to ventilate the collecting space; an external temperature sensor and an internal temperature sensor for measuring external and internal temperatures of the collecting space; and a temperature controller configured to control the above units to maintain the temperature in the collecting space to be equal to the external temperature.

A method analyses a gas dissolved in an insulating medium of a high-voltage device. The method includes: transferring the dissolved gas by an analysis device into a gas phase to obtain an analysis gas mixture; transporting the analysis gas mixture to an analysis sensor of the analysis device; generating a sensor signal as an output signal of the analysis sensor as a function of a composition of the analysis gas mixture; determining a first intermediate value based on the sensor signal and at least one disturbance value; determining a second intermediate value based on the first intermediate value and at least one specific value of the analysis device; and determining a value for a concentration of the dissolved gas in the insulating medium based on the second intermediate value.

An apparatus includes an enclosure body providing an enclosed space eliminating external sources of electromagnetic radiation with a door and a sample plate; a camera device mounted to the enclosure body and including a lens, an image sensor, and a processing unit; and a lighting system mounted in the enclosure body and having at least a first set of illumination elements, the lighting system being configured to illuminate a sample arranged on the sample plate, wherein the camera device is configured to detect radiation resulting from an interaction between illumination provided by the lighting system and the sample.

The present invention relates to a device and a method for the analytical and/or sensory determination of the release of an active substance or several active substances from a release system. In particular, the present invention relates to a device and a method for determining the release of an active substance or active substances, in particular of an odiferous substance or flavoring or an odiferous substance or flavoring mixture, from a capsule or a precursor. Furthermore, the present invention relates to a device and a method for determining the properties of a release system, in particular of a capsule or a precursor. Ultimately, the present invention relates to the use of the device and method according to the invention for the analytical and/or sensory determination of the release of one or more active substances from a release system.
