20100231368 | VEHICLE PRESENCE NOTIFICATION APPARATUS - A vehicle presence notification apparatus includes a modulating section to modulate an ultrasonic wave functioning as a carrier wave according to an audible sound; and a speaker to generate the audible sound as a notice sound by emitting the modulated ultrasonic wave in the air. As proceeding in the air, the modulated ultrasonic wave is gradually demodulated to thus become the audible sound. The audible sound posterior to the demodulation has a significant directivity like the ultrasonic wave. The notice sound is thus conveyed mainly to a pedestrian who is present in a dangerous area range where a danger needs to be taught. The sense of discomfort due to the notice sound is reduced for a pedestrian, who is not present in the dangerous area region or a person who is inside of another vehicle. | 09-16-2010 |

20080281882 | File management system - Since both a physical storage place and a logical storage place in a storage system are separately managed as a directory structure, or a hierarchical structure, even in such a case that the physical storage place has been changed, the logical storage place which is displayed to the user is not changed, and thus, the user can use the file while the user need not become aware of the change of the file. When the contents of a file is displayed, a physical storage destination of the file is acquired based upon both a reference path and a relative path of the file, and then, the file is acquired from the physical storage destination. | 11-13-2008 |
