Seven potentially harmful bifunctional carbonyls were measured in particulate and gaseous phases at a roadside site and a suburban site in an area about 30 km north-northwest from Tokyo metropolitan area in the Kanto region in Japan. For the first time, these compounds were measured in both phases with a time resolution of 2 h. We found that wind direction is an important parameter that affects the collection of these compounds near the source, and it can cover the effects of other important variables. Our results confirmed that motor vehicles and especially diesel fuelled vehicles are important sources of these compounds. Photochemical generation is also an important source of these compounds in the gaseous phase. Transportation from the urban area is also important,particularly in the aerosol phase.

This paper presents a guide following control(adriving support control) for a smart electric wheelchair, so that the wheelchair can follow a preceding person(guide). A walking guide is obtained from lasers can images by a nin-vehicle laser range sensor based on Kalman filter and data association, and the guide foot print is estimated. Based on position data of the foot print, acubicspline generate satarget path for the wheelchair. The wheelchair is controlled so that it can move along the guide foot print at a constant gap between the wheelchair and the guide. The experimental result validated the feasibility of the control method.
