Abstract
An active integrated circuit transponder with on-board power supply is mounted in or on a vehicle tire. A pressure sensor, a temperature sensor and a tire rotation sensor are mounted on a substrate along with the integrated circuit transponder chip, the power supply and an antenna. Upon receiving an interrogation signal from a remote source, the transponder activates the sensors to sense tire pressure and temperature and transmits an encoded radio frequency signal to the remote source containing serial, encoded tire identification, tire position on the vehicle, current tire pressure, current tire temperature and accumulated tire revolutions, as well as maximum and/or minimum tire and temperature pressure values encountered over a predetermined time period and other information specific to the tire.
