<p><P>PROBLEM TO BE SOLVED: To provide a composite sensor having a structure of the composite sensor for measuring simultaneously a pressure and an acceleration, capable of simplifying the structure of a sensor system, and miniaturizing the system. <P>SOLUTION: A composite sensor element having a structure capable of measuring independently the fluid pressure and the acceleration is built in the internal space of a tire, and the tire air pressure and the acceleration generated by tire rotation are detected separately independently, to thereby solve the problem. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
