Abstract

An alarm system for sending distress information over a communication link includes a sensor to be worn by a user. Distress information is transmitted from the sensor when the user is in a predetermined position indicative of an emergency, when the user moves outside of a predetermined safety area, when the power supply supplying power to the sensor is low, when the user voluntarily activates the sensor, and when the user is not wearing the sensor. In response to the distress information, audio and/or video communication between the user and personnel monitoring the user at a remote central office is provided in response to the distress information.

Claims

1. An alarm system for sending distress information over a communication link, the alarm system comprising:

a sensor worn by a user for determining when the user is in a predetermined position indicative of an emergency, the sensor generating a distress signal upon determining that the user is in the predetermined position;

a personal transceiver operable with the sensor for receiving the distress signal from the sensor and then transmitting the distress signal over a communication link; and

a central office transceiver operable with the personal transceiver for receiving the distress signal over the communication link from the personal transceiver, wherein the central office transceiver communicates with the personal transceiver upon receiving the distress signal to provide audio communication between the user and personnel operating the central office transceiver.

2. The alarm system of claim 1 wherein:

the central office transceiver communicates with the personal transceiver upon receiving the distress signal to provide video communication between the user and the personnel operating the central office transceiver.

3. The alarm system of claim 1 wherein:

the personal transceiver and the sensor are operable to monitor the distance therebetween, wherein the personal transceiver generates an improper distance signal when the distance between the personal transceiver and the sensor is greater than a predetermined distance.

4. The alarm system of claim 3 further comprising:

an audible alarm, wherein the personal transceiver transmits the improper distance signal to the audible alarm which generates an audible alarm signal in response thereto to notify the user that the user is at a distance farther than the predetermined distance from the personal transceiver.

5. The alarm system of claim 3 wherein:

the personal transceiver transmits the improper distance signal over the communication link to the central office transceiver, wherein the central office transceiver communicates with the personal transceiver upon receiving the improper distance signal to provide audio communication between the user and personnel operating the central office transceiver.

6. The alarm system of claim 1 further comprising:

a sensor monitor for determining if the sensor is being worn by the user, wherein the sensor monitor generates a sensor monitor signal upon determining that the sensor is not being worn by the user, wherein the personal transceiver is operable with the sensor monitor for receiving the sensor monitor signal from the sensor monitor.

7. The alarm system of claim 6 further comprising:

an audible alarm, wherein the personal transceiver transmits the sensor monitor signal to the audible alarm which generates an audible alarm signal in response thereto to notify the user that the sensor is not being worn by the user.

8. The alarm system of claim 7 wherein:

the personal transceiver transmits the sensor monitor signal over the communication link to the central office transceiver, wherein the central office transceiver communicates with the personal transceiver upon receiving the sensor monitor signal to provide audio communication between the user and personnel operating the central office transceiver.
