Seismic alarm and warning system
First Claim
1. A seismic alarm and warning system comprising:
- a. a 3-axis accelerometer;
b. at least one microphone;
c. at least one radio frequency module;
d. an electric-to-acoustic transducer; and
e. a controller operationally coupled with the 3-axis accelerometer, the at least one microphone, and the at least one radio frequency module, wherein the controller is configured to monitor signals from the 3-axis accelerometer to determine the presence of a seismic event, to enable the at least one microphone, and to monitor signals from the radio frequency module for emergency broadcastings, wherein enabling of the at least one microphone depends on the signals from the 3-axis accelerometer, wherein the microphone records surrounding acoustics and is enabled by the controller to pick up surrounding acoustics at a predetermined time interval and to reproduce the acoustics through the electric-to-acoustic transducer.

Abstract
An improved seismic alarm system designed to alarm users of an upcoming seismic event and other natural disasters, and aid victims'"'"' survival after an earthquake. The seismic alarm system includes an accelerometer, a controller, an acoustic-to-electric transducer for acoustic pattern detection, and RF module to receive emergency radio signals. The alarm system has central controlling unit that sets off an alarm after processing signals from several module and components: accelerometer detects seismic P wave acceleration changes for early earthquake detection; acoustic-to-electric transducer detects human acoustics or predetermined acoustic patterns, then initiates an alarm that brings rescue attention to survivors; RF module is tuned to receive emergency radio signals.
