20090033511 | EARTHQUAKE NOTICING SERVER, EARTHQUAKE NOTICING SYSTEM, EARTHQUAKE NOTICING METHOD, AND PROGRAM - In an earthquake noticing system according to the present invention, an earthquake noticing server receives focal data, calculates an expected time of arrival from a distance calculated from an occurrence location of an earthquake, a self-location and a focal depth, calculates an estimated seismic intensity from the occurrence location of the earthquake, the self-location and the seismic magnitude, calculates a corrected value of the expected time of arrival from the occurrence location of the earthquake, the self location and the location of a sub-terminal, and transmits the corrected value and estimated seismic intensity to the sub-terminal. | 02-05-2009 |
20090303070 | Distributed Decision Making Area Earthquake Warning System - An improved area earthquake warning system based on distributed decision making method, which makes such a system affordable in the region where wired and wireless mobile communication infrastructures are too expensive to build. The present invention can provide seconds, even tens of seconds for users to seek shelter to reduce injuries and lives lost. An exemplary embodiment of the invention described herein comprises a network of earthquake detection sites covering a geographic region with four types of earthquake detection sites. Instead of sending all raw ground motion signals to a remote central processing site, these detection sites send processed earthquake parameters to a nearby alarm site to decide if an earthquake alarm broadcasting should be triggered. This method shortens the response time, decreases the false alarm rate, and provides unlimited scalability. Further more, this invention provides self-check mechanism to eliminate system malfunction time. | 12-10-2009 |
20100207776 | COMMUNICATION DEVICE - A communication device of the present invention is provided with an evacuation direction portion receiving an earthquake early warning, and outputting a text image or sound for an evacuation direction. If the earthquake early warning is received under circumstances where a time adjusting portion cannot assure the accuracy of time kept by a timekeeping portion, the evacuation direction portion gives an evacuation direction based on earthquake information unassociated with the time. The evacuation direction portion is provided with a plurality of kinds of evacuation direction images or sounds. The evacuation direction portion determines an image or sound to be used for the evacuation direction based on an expected time period before a main tremor arrives calculated by an earthquake information calculating portion. Moreover, an evacuation direction registering portion receiving from a user, selection of evacuation direction data that the evacuation direction portion uses is provided. | 08-19-2010 |
20100277334 | COMMUNICATION SYSTEM FOR EMERGENCY TRANSMISSIONS AND METHOD THEREOF - A communication system for emergency transmissions and method thereof are disclosed. The communication system comprises a determination unit, a location detector, a message unit, and a wireless transceiver. The determination unit calculates an earthquake magnitude of an earthquake detected by a sensor, and determines whether the earthquake magnitude reaches a default threshold magnitude. The location detector acquires a coordinate of an earthquake location when the earthquake magnitude reaches the default threshold magnitude. The message unit then generates an emergency message embodying the coordinate of the earthquake location. The wireless transceiver then transmits the emergency message to at least one emergency center. | 11-04-2010 |
20130076524 | EARTHQUAKE ALARM - An earthquake alarm has a casing, a P-wave detecting device and an S-wave detecting device. The casing has a power supply, a controlling unit and a sound alarming unit. The controlling unit is electrically connected with the power supply. The sound alarming unit is electrically connected with the controlling unit. The P-wave detecting device has a longitudinally moving element and a contacting tab. The longitudinally moving element has a first end connected securely to the casing and a second end movable relative to the casing along a longitudinal direction. The contacting tab is spaced from and selectively contacting with the second end of the longitudinally moving element and is electrically connected with the controlling unit. The S-wave detecting device has a pendulum hung in the casing and a contacting ring. The contacting ring is mounted around the pendulum and is electrically connected with the controlling unit. | 03-28-2013 |
20130328688 | EARTHQUAKE WARNING SYSTEM - A method or system for detecting a seismic event includes detecting a primary wave of a seismic event using at least one sensor at a measurement location; using at least one parameter of the detected primary wave to determine an estimated peak ground intensity at the measurement location without determining the magnitude of the seismic event; determining an epicenter of the seismic event; and estimating the intensity of the seismic event at a specified location using the determined estimated peak ground intensity and the distance of the specified location from the epicenter. The epicenter can be determined using sensors at a single location. A noise detection system can filter out detected signals that correspond to local vibrations rather than seismic events. | 12-12-2013 |
20140266762 | SECURITY SYSTEM WITH EARTHQUAKE DETECTION - The present disclosure relates to approaches for detecting and monitoring for earthquakes using a control unit of a security system. A security system may include a plurality of sensors that detect alarm conditions and send alarm condition messages to a control unit for the security system. The control unit may be communicatively coupled to the sensors and configured to receive the alarm condition messages from the sensors. The security system may also include an earthquake sensor that senses earthquake conditions and sends an earthquake condition message to the control unit if it detects the earthquake condition. The control unit may include an alarm module. The control unit causes the alarm module to generate an alarm in response to receiving the earthquake condition message from the earthquake sensor. | 09-18-2014 |
20160189519 | Earthquake Warning Method and Earthquake Warning Broadcast System Thereof - The present disclosure provides an earthquake warning method. The earthquake warning method includes deploying a set of seismic device in a zone according to a criterion to detect an earthquake, generating a first earthquake warning signal when the earthquake is detected, receiving the first earthquake warning signal and a second earthquake signal; executing an decision determination according to the first earthquake warning signal and the second earthquake signal; sending first earthquake warning signal or a second earthquake signal according to the decision determination and broadcasting an earthquake warning. | 06-30-2016 |
