Vibration transmission system for ignition devices |
摘要 |
In a system for the transmission of ground vibrations to an ignition device, a frequency filter and a timing circuit are disposed between the sensor and the ignition device. The timing circuit permits the feeding of the output signal of the frequency filter to the ignition device only after the mechanical vibrations producing the output signal of the frequency filter have acted on the sensor for a predetermined, variable period of time.
