Abstract: The present invention relates to a steel structure assembling system. The steel structure assembling system applied to assemble a movable steel beam and a fixed steel structure includes a rotating control device disposed on the movable steel beam for adjusting a relative position of the movable steel beam with respect to the fixed steel structure; an alignment target disposed on the fixed steel structure; and an image sensor disposed on the movable steel beam, sensing a target image of the alignment target and transmitting the target image to a ground operator to render the ground operator to operate the rotating control device to adjust the relative position of the movable steel beam in accordance with the acquired target image.

Abstract: An early warning method and a device for preventing a wheelchair from tipping over are described. The early warning method includes projecting a laser light pattern, scanning the laser light pattern, making a comparison to determine whether the ground is a barrier terrain, and issuing an early warning to the user in situations of risk. The laser light pattern is projected onto the ground and compared with a standard pattern. The early warning is generated and is one selected from a group consisting of a beep, a warning message and a vibration to alert the wheelchair user to the danger of the barrier terrain.

Abstract: A medication dispensing system, method and non-stationary computer readable recording medium thereof are provided. The medication dispensing system includes a medication dispenser adapted to accommodate a plurality of medicine units for dispensation. The medication dispenser includes a user interface unit, an identifier, and a processor. The identifier is adapted to communicate with an identifiable unit. The processor is coupled to the user interface unit and the identifier.
