A mobile communication terminal mounted in a vehicle sends a state parameter to a CDMA network through an antenna. The refresh control circuit generates the refresh execution signal 2n times in response to one supply of the refresh command, where n is an integer equal to or larger than 0 and equal to or less than k. Communication is enabled between the player and the individual. The method also includes directing warm air from the ceiling to the floor and storing heat in the floor, apparatus on the floor and ground under the floor. The display portion is mounted on a portion of a handle in the field of vision of a rider of the bicycle, and it has functions of receiving and processing signals transmitted from the transmit portion, and displaying prescribed information. Sensor positions and bearings are transformed into the triangulation reference system where the triangulation is performed.
