摘要： According to one embodiment, a structure evaluation system includes at least three or more sensors, a position locator, and an evaluator. The three or more sensors are arranged on surfaces different from a surface to which an impact is applied with respect to a structure at different intervals in a first direction of the structure and a second direction orthogonal to the first direction and detects elastic waves generated from the structure. The position locator locates a position of a source in which the elastic waves are generated on the basis of the elastic waves detected by each of the three or more sensors. The evaluator evaluates a deterioration state of the structure on the basis of information based on a position location process of the position locator and information indicating a position where the impact is applied.

摘要： According to an embodiment, a detection system includes a plurality of sensor nodes and a sensor module. The plurality of sensor nodes detects sound waves generated from a prestressed concrete and converts the detected sound waves into detection signals. The sensor module is connected to the plurality of sensor nodes and receives the detection signals. The plurality of sensor nodes includes the sensor nodes in an operating state and the sensor nodes in a dormant state in which power consumption is held down as compared to the operating state. When magnitude of the detection signals is equal to or greater than a first threshold value, the sensor module switches the sensor node in the dormant state to the operating state.

摘要： According to one embodiment, a structure evaluation system includes a plurality of sensors, an acquirer, a calculator, and an evaluator. The plurality of sensors detects elastic waves generated from the structure. The acquirer acquires detection information for an evaluation target period in which information on at least an amplitude of each elastic wave detected by each of the plurality of sensors is associated with time information on the time when each elastic wave is detected. The calculator calculates an evaluation value, which is a slope of an amplitude scale-based frequency distribution of elastic waves, every predetermined period based on the acquired detection information for the evaluation target period. The evaluator evaluates a deterioration state of the structure based on the time-series data of each evaluation value calculated every predetermined period.

摘要： According to one example, an optical element assembly includes a transparent rod, a mirror and a light emitting element. The rod transmits light of first wavelength region made incident on a first end of the rod and emits the light of the first wavelength region from a second end of the rod. The rod absorbs light of a second wavelength region falling out of the first wavelength region. The mirror is disposed on a side of the first end. The mirror transmits one of the light of the first and second wavelength regions, reflects the other. The light of the first and second wavelength regions are made incident on the first end of the rod. The light emitting element emits light of the second wavelength region made incident on the first end of the rod through the mirror.

摘要： To solve a new problem which has been produced due to adoption of a recording method using relaxation oscillation, the laser output control device suppresses unnecessary relaxation oscillation while increasing an averaged light quantity between recording pulses to obtain reflected light quantity which is necessary for tracking and focus controlling. A laser modulation control circuit includes a recording pulse output unit (75A) which outputs recording pulses for making relaxation oscillation as the recording pulses, a bias current output unit (75B) which outputs a constant bias current between the recording pulses, and a high-frequency overlap unit (75D) which overlaps the high-frequency signal on the constant bias current between the recording pulses, and controls so as to have times at which current values at a start edge and an end edge of the high-frequency signal are almost consistent with a value of the constant bias current.
