Distress call emitting device

摘要

The distress call emitting device comprises an earthquake sensor for detecting an earthquake of a prescribed intensity or greater and/or a receiver for receiving a radio signal from a remote transmitter. Therefore, even when the user is unable to call for a help, the distress call emitting device of the present invention produces a distress call in his behalf by sound and/or light. The distress call can be initiated either by detecting the intensity of the earthquake or by operating a remote transmitter which may be carried by the user. If the device is linked to a telephone line, the distress call can be made also through a telephone line. Thus, even when the user is too weak to call for a help by his own effort, the device is either automatically activated by an earthquake or remotely activated by pressing a switch on a portable transmitter.
