Abstract: A formwork panel includes a heat insulating material forming one side of the formwork panel, and a support forming the other side of the formwork panel and detachably coupled to the heat insulating material, in which the size of the support corresponds to the size of the heat insulating material, and the support includes an edge part surrounding the opening part and having no opening, and the support includes an opening part having at least one opening such that, in a structure in which the support and the heat insulating material are coupled to each other, the heat insulating material is exposed to the outside.

Abstract: A distance measuring device and a distance measuring method using a laser are disclosed. The distance measuring device includes a laser module that emits a laser to a target point spaced apart from the distance measuring device, and detects a laser reflected from the target point, an acceleration sensor that measures an acceleration of the distance measuring device and outputs an acceleration signal, a gyro sensor that measures an angular velocity of the distance measuring device and outputs an angular velocity signal, and a microprocessor that calculates a distance between target points using acceleration information related to the acceleration signal, angular velocity information related to the angular velocity signal, and information related to the laser.

Abstract: An unmanned operating method for a crane for moving containers in use in a harbor and the apparatus therefor compensates the influence due to a disturbance such as the wind in driving the crane, detects the position and posture of the spreader and crane, thereby allowing the container to be attached and detached automatically. Accordingly, a crane automation for moving containers is achieved.
