A filter for a cigarette and a filter-tipped cigarette having a high degree of freedom in control of filtering-efficiency of smoke are provided. The first subsystem connects a steering wheel with a mechanical link adapted to turn a first wheel of the vehicle. This scheme, when a plurality of applications is run on different threads, prevents parameters etc. The method determines if any of the measured end cell temperatures are outlying by comparing each end cell temperature measurement to the average. A temperature rise in the catalyst above pyrolysis temperature is achieved without the addition of air or oxygen.
