Remotely actuated tire pressure sensor

摘要

A tire pressure sensor is provided including a transducer unit having a mechanical-to-electrical transducer disposed in intimate contact with the pressurized region of a tire. The transducer senses tire pressure and outputs an electrical signal representative thereof. The transducer unit further includes a response signal generator which transmits a signal representative of tire pressure. A hand-held remote display unit receives the transmitted signal and converts it to visual indicia of tire pressure, for example on a three-digit digital display.
