  • Patent number: 11360051
    Abstract: The present disclosure provides a construction structure corrosion measurement sensor having accuracy higher than that of conventional sensors, and a method for measuring corrosion by using the same. To this end, the present disclosure provides a sensor assembly including an eddy-current sensor including an insulator a coil surrounding the outer periphery of the insulator. The present disclosure also provides a construction structure corrosion measurement method including the steps of: positioning a sensor assembly next to a rebar inside a construction structure in parallel with and adjacent to the rebar; applying a voltage to the sensor assembly; measuring a voltage generated by an eddy current resulting from the adjacent rebar; and conducting measurement at a predetermined time interval so as to measure a voltage change.

  • Patent number: 11187568
    Abstract: The present invention provides a curb for measuring the flood depth in an urban area, more particularly, to a curb for measuring the flood depth in an urban area, which is configured to demarcate the boundary between a vehicular roadway and a pedestrian sidewalk to measure the flood depth so that the flood depth in the urban area can be measured without the necessity for additional installation of a separate structure. In particular, the present invention has an effect in that an air contact type water level gauge is installed in a first space of a main body to measure the flood depth, i.e., the level of flooding water based on the internal air pressure of a cylindrical tube so that a pressure sensor is not brought into close contact with the flooding water to prevent corrosion of the pressure sensor, thereby reducing the maintenance and repair costs.

  • Patent number: 8669078
    Abstract: Disclosed herein are ammonia-specific 5?-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5?-XMP aminase. The resulting 5?-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5?-XMP into 5?-GMP. Thus, the ammonia-specific 5?-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5?-XMP into 5?-GMP.

    Abstract: The present invention related to a driving circuit including a level shifter. The driving circuit according to exemplary embodiment of the present invention includes a first level shifter, a second level shifter, and a gate driver. The first level shifter includes a path along which a pulse-on current flows in response to an on-control signal and a path along which a pulse-off control flows in response to an off-control signal. The second level shifter includes a path along which an on-current flows in response to the on-control signal and a path along which an off-control flows in response to the off-control signal. The gate driver turns on the switch in response to the pulse-on current, maintains the turned-on switch in the turn-on state in response to the on-control current, turns off the switch in response to the pulse-off current, and maintains the turned-off switch in the turn-off state in response to the off-control current.
