Abstract

An emergency signal device for use by those with medical conditions having means to detect the occurrence of a change in attitude in conjunction with a shock and an alarm means including audible messages alerting bystanders to the wearer'"'"'s medical problems. The emergency signal device may also include means to activate the alarm means in the event the wearer exits a pre-specified geographic area, or at pre-specified time intervals. The emergency signal device may also include cellular and global positioning satellite means to automatically determine and transmit the location of the emergency signal device to a cellular base station upon activation of the alarm. The emergency signal device may further include means for activating existing emergency telephone notification systems.

Claims

1. An emergency signal device comprising:

a pre-programmed microprocessor, said microprocessor capable of accepting serial and parallel data input and having primary check and alarm modes and having pre-programmed attitude and shock algorithms and thresholds and having pre-programmed attitude and delay timing routines;

means for detecting the attitude of said emergency signal device, said means for detecting the attitude having data output capable of being received by said microprocessor;

means for recording and storing multiple voice and alarm signals capable of activation by a signal from said microprocessor and having input means to record multiple voice messages; and

an external speaker for playing said multiple voice messages and alarm signals.

2. The emergency signal device of claim 1 further comprising means of manually activating and de-activating said alarm mode.

3. The emergency signal device of claim 1 further comprising a periodic messaging mode.

4. The emergency signal device of claim 1 father comprising means to detect the exit of said emergency signal device from an acceptable geographic area.

5. The emergency signal device of claim 1 further comprising a means to activate existing telephone emergency notification systems.

6. An emergency signal device comprising:

a pre-programmed microprocessor, said microprocessor capable of accepting serial and parallel data input and having primary check and alarm modes and having pre-programmed attitude and shock algorithms and thresholds and having preprogrammed attitude and delay timing routines;

means for detecting the attitude of said emergency signal device, said means for detecting the attitude having data output capable of being received by said microprocessor;

means for storing multiple pre-recorded voice and alarm signals capable of differential activation by a signal from said microprocessor; and

an external speaker for playing said multiple voice messages and alarm signals.
