Abstract: A mobile navigation system includes: a radar antenna carried by the vehicle, and emitting first and second sensing beams at first and second time points, respectively; first and second retro-directive antennas or beam-reflecting objects disposed at first and second positions, respectively, and being a specific distance from each other; and a processing device electrically coupled to the radar antenna. The first and second retro-directive antennas or beam-reflecting objects respectively return first and second retro waves corresponding to a direction of the first sensing beam, and respectively return third and fourth retro waves corresponding to a direction of the second sensing beam. The processing device receives the first, second, third and fourth retro waves, and determines a moving direction of the vehicle according to the first, second, third and fourth retro waves and the specific distance.

Abstract: A self-monitoring tire includes a tire body and a tire pressure sensor. The tire body includes a tread rubber for contact with ground, a bead for coupling to a rim, and a sidewall structure including two portions disposed at opposite sides of the tread rubber, and extending from opposite sides of the tread rubber to the bead. The tire pressure sensor is disposed between respective outward surfaces of the two portions of the sidewall structure, and secured on or embedded in either one of the two portions of the sidewall structure.
