An attributed roadway trajectory comprises at least one ordered series of attributed roadway trajectory points, which are spaced along a curve that is defined in a terrestrial coordinate frame and tracks an along-roadway physical feature of a real-world roadway segment portrayed in a point cloud. When a recording medium on which a digital content is recorded has been sold from a final seller to an end user through the distribution channel of the recording medium, the sales management device communicates the sales information to the license management device. These electric charges are read-out and converted into the initial image signal. The second driver is configured to drive a second switching signal at the second output in the direct drive mode. In some embodiments, opposing side electrodes serve as input and output terminals of a respective feedthrough filter. The first cleaning unit moves the first cleaning member while pressing the first cleaning member against a surface of the heating member.
