Methods and systems for seismic signal detection |
| 摘要 |
<p>The invention concerns methods and systems utilizing seismic sensors (10) configured or designed for use in seismic signal detection. An electrical current is applied to a seismic sensor (10) such that the moving coil (16) is located at a neutral position relative to the magnetic field in the seismic sensor (10) to compensate for gravitational acceleration.</p> |
