Abstract: An apparatus for collecting contaminated air, including: an air pollution detecting unit for monitoring pollution status of air existing in the pertinent area; an air collecting unit for collecting and storing part of the air; and a control unit for comparing data about the pollution status monitored by the detecting unit with preset critical values and commanding the collecting unit to collect a part of the air when data about the pollution status is equal to or greater than the critical values. Since contaminated air is collected by monitoring the pollution status of contaminated air existing in the atmosphere of a pertinent area or the gaseous contaminant-containing air discharged from sources in real time, it is possible to collect air pollution evidence. The collecting unit provided at the outlet of a source, allows air pollution data to be stored after analyzing collected air, making it possible to lawfully sanction air polluter.

Abstract: The present invention relates to a system for providing road information using a navigation device, and provides road information detected by a road information provision device installed on the road to a driver by transmitting the road information to a navigation device in a wireless manner. Accordingly, the present invention has the advantage of a driver being able to promptly and precisely perceive road information, which has been detected by a road information provision device installed on the road and has been transmitted to a navigation device in a wireless manner, thus allowing the driver to safely drive the vehicle. Further, there is the advantage of road information being able to be provided directly from a road information provision device, so that there is no need to pass a separate facility for collecting, analyzing and providing road information or to subscribe to a separate service for road information.
