One embodiment of the present invention sets forth a technique for generating and transmitting video frame data from a graphics processing unit to a color field sequential display device capable of displaying an auto-stereoscopic image. A basic signal generating unit generates a basic signal based on a vibration noise frequency. A stationary interior housing circumscribes the ring, with an interior surface in frictional contact with the ring. The third insulating film exposed at the bottoms of the wire trenches and the first insulating film exposed at the bottoms of the via holes are removed by etching under a condition in which the third insulating film is selectively etched. Apparatuses for communicating a ranking characterizing a portion of a roadway are described.
