Abstract
A method for a system includes applying power to a MEMS device while inhibiting applying power to a processor, thereafter determining first sensed data with the MEMS device in response to first event data, when the first sensed data exceeds a first threshold, determining second sensed data with a second MEMS device in response to second event data, when the second sensed data exceeds a second threshold, applying power to the processor, determining with the processor whether a seismic event is occurring in response to the first and the second sensed data, directing with the processor, an electronically-controllable mechanism to shut-off a utility supply, in response to the seismic event being determined.
