  • Identifier automatic assigning data processing board, data processing module including identifier automatic assigning data processing board and data processing system including data processing module
    Patent number: 11507390
    Abstract: A data processing board according to an embodiment of the present disclosure includes a data processing module including at least one data processing board for automatically assigning an identifier according to the voltage value measured in the internal circuit and a communication board for transmitting and receiving signal to/from the data processing board, and a data processing system including the data processing module and a monitor collecting device for selecting and parallel-processing the data received from the data processing module.
    Type: Grant

  • Nozzle block, wet scrubber device comprising nozzle block, and fume hood having wet scrubber device
    Patent number: 11253815
    Abstract: In a nozzle block, a fluid is uniformly sprayed over an entire housing inside through a spray nozzle with the rotation of a nozzle coupling part, thereby increasing a contact ratio of the fluid with contaminated gas and dramatically improving the purification efficiency. Additionally, a fluid for cleaning contaminated gas is allowed to flow opposite to a flow of contaminated gas, so that the contaminated gas and the fluid cancel out, and the contact ratio increases.

  • Gas leak monitoring system
    Patent number: 11215524
    Abstract: A gas leak monitoring system according to an embodiment of the present disclosure may be easily applied to a laboratory or the like to which a large amount of gas is supplied and also may detect a gas leak economically and efficiently. In addition, according to an embodiment of the present disclosure, it is possible to immediately check a gas leak and take a measure through a user terminal or a management module to prevent a large accident caused by the gas leak in advance.
