Abstract: Electronic transponders (20) embedded within or on vehicle tires (40) are electromagnetically actuated by signals from an interrrogator coil (14). The transponder includes a receiver/transmitter coil (26) of one or more loops of wire (54) strategically placed along the sidewall or in proximity to the tread face of the tire. The transponder responds to actuation by producing a shifted frequency modulated with synchronization pulses and unique device identifying digital information. The transponder data stream can also include information on the condition and environment of the tire. By appropriate placement of the tire transponder coils and the interrogator coils, dynamic reading of the tire data is possible even with the vehicle in motion.

Abstract translation: 嵌入在车辆轮胎（40）内或车辆轮胎（40）上的电子转发器（20）通过来自螺旋桨线圈（14）的信号被电磁致动。 应答器包括一个或多个线圈（54）的接收器/发射器线圈（26），该线圈（54）沿着侧壁或者靠近轮胎的胎面面有策略地放置。 应答器通过产生用同步脉冲调制的移位频率和识别数字信息的唯一设备来响应致动。 应答器数据流还可以包括关于轮胎的状况和环境的信息。 通过轮胎转发器线圈和询问器线圈的适当布置，即使车辆运动，轮胎数据的动态读取也是可能的。
