  "textContent": "The method involves measuring air pressure present in vehicle tires by a pressure sensor, and transmitting pressure information by a high-frequency transmitter. Interrogation signals (10) are received by a low-frequency receiver, where transmission activity of wheel electronics is triggered by reception of the interrogation signals. The interrogation signals are transmitted as a pulse train comprising a command section (14) to encode a transmission instruction for the wheel electronics and an adjustment section (12) having several pulses (12a) before the command section. An independent claim is also included for a tire pressure monitoring system comprising wheel electronics with a pressure sensor for measuring air pressure present in vehicle tires.",
