Abstract: A tire identification system for use in a vehicle, a tire pressure monitoring system using the same and a method for tire identification are disclosed. The vehicle comprises a plurality of tires and a receiver. Each of the tires comprises a tire identification code. The receiver is used to receive signals. The tire identification system comprises a plurality of memory cards and a remote control device, wherein each of the memory cards comprises a memory card identification code that corresponds to each tire identification code, respectively. Moreover, each of the memory cards can be detachably connected to the remote control device in response to each of the tires. The remote control device comprises a signal transmitter to send a signal with each of the memory card identification codes to the vehicle.

Abstract: A radio communication method and system for using pattern variation to identify a pre-detection signal is provided, which uses a transmitting end and a receiving end to execute communication. The transmitting end outputs a radio signal with the pre-detection signal, which includes at least a first transmitting waveform, a second transmitting waveform and a third transmitting waveform. The cycles of the waveforms are changed according to a first predetermined relation. The receiving end is used to receive the radio signal and calculate the cycle of each receiving waveform. If the cycles of the first receiving waveform, the second receiving waveform and the third receiving waveform of the radio signal are changed according to a second predetermined relation corresponding to the first predetermined relation, the receiving waveforms are used as the pre-detection signal.

Abstract: A battery-less tire pressure monitoring system is disclosed, which is installed in a tire to monitor the status of the tire, such as the air pressure of the tire. The battery-less TPMS has a tire pressure sensor, and a power generation device, wherein the tire pressure sensor is installed on the fixture in the tire, in order to monitor the status of the tire. Besides, the power generation device of the battery-less TPMS is also installed on the fixture of the tire, and is electrically connected with the tire pressure sensor to provide electrical power for the operation of the tire pressure sensor.
