Technical Examples
  1. In a vehicle tire air pressure detection system, a charging electromagnetic wave is transmitted for a predetermined period from a vehicle chassis side and stored as a charge voltage in a transmitter unit attached to a tire wheel. When the charge voltage reaches a predetermined level, a sensor in the transmitter unit detects a tire air pressure and a transmitter/receiver of the transmitter unit transmits a detection data on an electromagnetic wave in the same frequency band as the charging electromagnetic wave after the predetermined period from a time point at which the charge voltage has reached the predetermined level. Thus, interference between the charging electromagnetic wave and the electromagnetic wave of the detection data is prevented.
