A brake system for a vehicle having a hydraulic brake system and a regenerative brake system and a method of controlling the same is provided. The semiconductor device includes a semiconductor substrate including an active region, a transistor that is formed in the active region of the semiconductor substrate, an interlevel insulating layer that is formed on the semiconductor substrate and a contact plug that is formed in the interlevel insulating layer and that is electrically connected to the transistor. Conclusion can be made that there has been a relatively large change in the relative position of the electronic cassette and the image reading device if the detected value of the separation distance becomes greater than the reference value by the specific value or more, and consequently emission is halted of the laser light from the electronic cassette and the image reading device. One advantage of the suspension composition provided herein can be for aerial spraying of active ingredient such as herbicides, insecticides, or other growth regulating compounds. When the slider assembly is in its direct drive position, the slider collar is fully received within the profile of the input gear and thereby adds no additional length to the transmission. The device uses multiple digital cameras, arranged with overlapping fields of view, to capture image data covering an entire 360\xb0 scene.
