Abstract

An alarm for sending out distress information when the user is in an abnormal position or when the user wishes to alert others of a distress condition. The alarm includes an omni-directional tilt switch and a transmitter. When the tilt switch has passed a critical angle, a signal is sent to a delay circuit. The delay circuit waits for a predetermined period of time, such as ten seconds, before enabling a transmitter. The transmitter then sends information over a communication link, signaling others that the user is in need of assistance. The invention further includes an alarm for alerting the user that the predetermined position of the tilt switch has been satisfied and that, after the predetermined delay, the distress information will be transmitted over the communication link unless deactivated by the user.

Claims

1. An alarm for sending distress information over a communication link comprising, in combination:

A multi-directional tilt switch for emitting a tilt signal in response to being turned to a predetermined position, whereby said predetermined position is indicative of a user'"'"'s emergency;

delay means for receiving said tilt signal, waiting a predetermined period of time, and thereafter sending an enable signal;

transmission means for receiving said enable signal and responsively transmitting said distress information over said communication link;

clear means for stopping transmission of said distress information;

distress information alarm means for receiving said tilt signal and alerting the user that the predetermined position is satisfied, whereby said user is informed that unless said clear means is activated, said distress information will be transmitted over said communication link after said predetermined period of time has elapsed;

activation means for selectively enabling and disabling said alarm, whereby said user may voluntarily disable said alarm and then said multi-directional tilt switch may turn to said predetermined position without triggering transmission of said distress information over said communication link; and

second alarm means for reminding said user to re-enable said alarm after said multi-directional tilt switch first turns to said predetermined position and then turns to another position.

2. The alarm of claim 1 further comprising panic switch means for being manually activated and triggering transmission of said information over the communication link.

3. The alarm of claim 1 wherein the communication link comprises:

a transmitter for receiving a digital pulse from said delay means and responsively transmitting a radio-frequency signal; and

a telephone auto-dialer for receiving the radio-frequency signal from said transmitter and thereupon triggering transmission of said distress information to an assist station over a telephone line.

4. The alarm of claim 1 wherein the delay means includes a timer coupled with a counter, whereby a digital pulse transmitted to said transmitter after a predetermined delay.

5. The alarm of claim 4 further including counter reset means for resetting the counter after the predetermined delay has expired.

6. An alarm for sending distress information over a communication link comprising, in combination:

A multi-directional tilt switch for emitting a tilt signal in response to being turned to a predetermined position, whereby said predetermined position is indicative of a user'"'"'s emergency;

delay means for receiving said tilt signal waiting a predetermined period of time, and thereafter sending an enable signal;

switch enable means for being manually activated and issuing a change signal to change an enable state of said transmitter;

transmission means responsive to said enable signal from said delay circuit, for transmitting a radio-frequency signal;

receiver means for accepting said radio frequency signal and responsively using distress information over a telephone line;

clear means for being manually activated by said user and responsively stopping said delay means from issuing an enable signal;

a beeper for issuing a sound wave signal;

beeper activation means for receiving said tilt signal and responsively activating said beeper to alert said user that said predetermined position was satisfied and that, after said predetermined time, said distress information will be issued; and

second beeper activation means for receiving said tilt signal and change signal and responsively activating said beeper to alert the user that said transmitter is disabled and said tilt switch is in said predetermined position, whereby said beeper reminds the user to re-enable the transmitter.

7. The alarm of claim 6 further comprising a panic switch for being manually activated and triggering transmission of said radio-frequency signal.

8. The alarm of claim 6 wherein said receiver means includes

a telephone auto-dialer for receiving the radio-frequency signal and responsively dialing a telephone number;

and

a telephone transmitter for sending distress information over a telephone line.
