ABSTRACT:
An improved safety related compact hand-portable apparatus for home or office use, EQ-Alert.TM. is ceiling or shelf mountable, activating upon sensing a minimum-threshold earthquake preferably of about 3.25/Rictor-scale intensity, instantly emitting a series of approximate 110-decibel level siren-alarms; preferably along with activation of a safety-lamp to illuminate an immediate floor-area in event of community power-outage. A preferably dry-cell powered dc/electronic IC-chip timer-circuit, limits duration of the audible-alarm, triggered by sufficient movement of an internal omni-directional mercury n.o./jiggle-switch. Upon completion of the timed audible-alarm and optional voice-chip announcement, the timer-circuit sequences a conventional integral superheterodyne-AM/radio user has preset to a local Conelrad
ews-station, for ongoing notification of any earthquake rescue procedures. Optional provision for plug-in circuit-modules, facilitates adding of allied safety-units, such as substantially conventional smoke-alarm, and carbonmonoxide-alarm detectors, sharing the audio-transducer and IC-microprocessor; to issue forth separate short programed voice-announcements as to the detected hazards.
