Active integrated circuit transponder and sensor apparatus for transmitting vehicle tire parameter data

摘要: An active integrated circuit transponder (10) with on-board power supply (14) is mounted in or on a vehicle tire (60). A pressure sensor (50), temperature (110) and rotation (120) are substrate (12) along the chip, an antenna (36). Upon receiving interrogation signal from remote source (80), activates sensors to sense transmits encoded radio frequency (80) containing serial, identification, position vehicle, current pressure, accumulated revolutions, as well maximum and/or minimum values encountered over predetermined time period other information specific tire.
