  • Publication number: 20240123363
    Abstract: Disclosed is a gyro drop apparatus including a tower standing on and extending from an installation surface; a gondola provided to ascend and descend along the tower and boarded by users; a driving supporter configured to drive the gondola to ascend; a brake configured to decelerate the gondola so that a fall speed of the gondola can be within a normal deceleration range when the gondola is in free fall; an abrupt-fall detector configured to detect whether or not the gondola falls abruptly or unintentionally; an emergency safety unit provided below the gondola and switching over between a standby state to be ready for operation and an operating state to absorb shock of the gondola; and a controller configured to control the emergency safety unit to switch over from the standby state to the operating state when the abrupt-fall detector detects that the gondola falls abruptly or unintentionally.

  • Patent number: 10684383
    Abstract: Provided is an earthquake response system using a seismic motion sensor. The seismic motion sensor of the earthquake response system includes: a sensor unit measuring a sensor value including peak ground acceleration (PGA) of the ground due to shaking; a seismic motion sensing unit sensing seismic motion on the basis of a seismic motion sensing result value calculated from an artificial neural network that uses the peak ground acceleration as input when the peak ground acceleration satisfies a seismic motion sensing condition; a seismic motion determiner determining generation of final seismic motion on the basis of a seismic motion determination parameter calculated from the sensor value on the basis of the seismic motion sensing result; a shaking grade calculator calculating a shaking grade of the determined final seismic motion through the peak ground acceleration; and a communication unit notifying the shaking grade of the final seismic motion.

  • Patent number: 9434600
    Abstract: Disclosed herein is a fluid collecting apparatus. The apparatus comprises a body disposed adjacent to fluid conveying or storing equipment to limit a moving path of fluid leaked from the equipment, a collector connected to the body to collect the leaked fluid, and a controller connected to the body to control an operation of the collector. The fluid collecting apparatus is capable of safely collecting fluid, for example, harmful gas leaked from fluid conveying or storing equipment.
