Abstract: A battery charging and swapping system includes a plurality of charging seats, a first charging station, a first charging rail and a first conveying unit. The charging seats are operable to enter a first conveying space defined by the first charging station so as to be stored. The first charging rail is disposed at the first charging station, and supplies electrical energy to the charging seats. Via the first conveying unit, when one of the charging seats entering the first conveying space is carried and moved by the first conveying unit, at least one of the rest of the charging seats in the first conveying space is pushed by the one of the charging seats to move along the first conveying space.

Abstract: A traffic light control system includes a first traffic light apparatus and multiple second traffic light apparatuses for displaying a direction pattern indicating intended movement of an emergency vehicle about to pass through an intersection, and a controller storing direction patterns each indicating a direction to take and a specific movement manner of the emergency vehicle. In response to a direction signal corresponding to one of the direction patterns, the controller controls the first traffic light apparatus to display the one direction pattern, and controls each of the second traffic light apparatuses to display a corresponding oriented version of said one direction pattern based on a location of the second traffic light apparatus.
