| 摘要 |
A multiple sensing device has sensors, mounted on a common rotatable shaft (11), for sensing magnetic field, electric field, gas flow, angular acceleration, and linear acceleration. The latter three of the sensing devices employ piezoelectric crystals (13, 16, 14) as the sensors, while the magnetic field sensor employs a pair of rotating coils (10) and the electric field sensing device employs a pair of rotating electrodes (12). |
