Title:
LOW FREQUENCY FOLDED PENDULUM AND VERTICAL SEISMIC SENSOR UTILIZING SUCH A FOLDED PENDULUM
Document Type and Number:
WIPO Patent Application WO/2012/147112
Kind Code:
A3
Abstract:
The present invention concerns a folded pendulum, that can be realized even as a monolithic pendulum, that is not positioned in its traditional horizontal configuration, and as such developed and known in the prior art, rather in the vertical configuration, i.e. rotated by 90°, either in the clockwise or anticlockwise direction. In particular, the version of such vertical folded pendulum in monolithic configuration allows more compact realizations, characterised by high decouplings of the vertical degree of freedom from the other degrees of freedom as well as optimal mechanical quality factors.
