发明名称 Device for the detection of data of passing vehicles on a road.
摘要 The sensor (100) is placed in a groove (120) formed in the top surface of a road (111). A first section of the sensor (20) has a U-shaped cross-section and is placed in the groove. A piezoelectric, coaxial cable (10) is inserted in the narrow channel defined by the first section. A second section (30) is fitted into the top of the U-shaped channel above the piezoelectric cable. The second section fills the remaining space above the cable to leave a flat top surface. <IMAGE>
