    Abstract: The inventive concept relates to a device that detects a leak of a liquid leaked from a sinkhole, water pipe or oil pipeline under the ground. In the detection device of the inventive concept, a plurality of reception devices disposed on the surface of the earth simultaneously receive an ultrasonic signal transmitted from a transmission device under the ground and a radio frequency (RF) signal synchronized with the ultrasonic signal. Also, by measuring an arrival time of the ultrasonic signal by using the wireless signal received by each reception device as a triggering signal, a leak range of a liquid leaked from a sinkhole, water pipe or oil pipeline on a signal path between the transmission device and the reception device is detected.

    Abstract: The present invention relates to an unrestrained neural signal monitoring device and system configured to enable an unrestrained test by being mounted on a living test subject such as a mouse, the device comprising a neural signal detector detecting a neural signal of the test subject such as a brain wave, a first light emitting part outputting a colored light for position tracking, a second light emitting part outputting a colored light for neural signal display, and a controller for controlling the first and second light emitting parts in response to the neural signal detected through the neural signal detector. Because movement of a test subject is unrestrained, a natural activity of the test subject is enabled to thereby prevent an interactive behavior of a group from being restrained.
