Abstract

A personal alert safety system comprises a housing adapted to be worn by a user. An accelerometer is in the housing. An alarm device is operatively associated with the housing. A control in the housing is operatively connected to the accelerometer and the alarm device. The control is configured to operate the alarm device responsive to select acceleration movement of the housing sensed by the accelerometer.

First claim

The invention claimed is:

1. A personal alert safety system comprising:
a housing adapted to be worn by a user;
an accelerometer in the housing;
an alarm device operatively associated with the housing; and
a control in the housing operatively connected to the accelerometer and the alarm device, the control being configured to operate the alarm device responsive to select acceleration movement of the housing sensed by the accelerometer.

2. The personal alert safety system of claim 1 wherein the select acceleration movement comprises a single tap of the housing in any direction.

3. The personal alert safety system of claim 1 wherein the select acceleration movement comprises a double tap of the housing in any direction.

4. The personal alert safety system of claim 1 wherein the accelerometer sends an interrupt signal to the control.

5. The personal alert safety system of claim 1 wherein the alarm device comprises a speaker.

6. The personal alert safety system of claim 1 wherein the housing is adapted to be mounted to a pressure hose of a self contained breathing apparatus and further comprising a pressure sensor operatively connected to the control for sensing pressure in the pressure hose and the control is automatically activated responsive to sensed pressure.

7. The personal alert safety system of claim 1 wherein the housing is adapted to receive an activation key operatively associated with the control and wherein the control is activated responsive to removal of the activation key.

8. A method of generating an emergency alarm in a personal alert safety system comprising:
providing a housing adapted to be worn by a user, the housing including an accelerometer in the housing and an alarm device; and
providing a control in the housing operatively associated with the accelerometer and the alarm device, the control operating the alarm device responsive to select acceleration movement of the housing sensed by the accelerometer.

9. The method of generating an emergency alarm in a personal alert safety system of claim 8 wherein the select acceleration movement comprises a single tap of the housing in any direction.

10. The method of generating an emergency alarm in a personal alert safety system of claim 8 wherein the select acceleration movement comprises a double tap of the housing in any direction.

11. The method of generating an emergency alarm in a personal alert safety system of claim 8 wherein the accelerometer sends an interrupt signal to the control.

12. The method of generating an emergency alarm in a personal alert safety system of claim 8 wherein the alarm device comprises a speaker.

13. The method of generating an emergency alarm in a personal alert safety system of claim 8 wherein the housing is adapted to be mounted to a pressure hose of a self contained breathing apparatus and further comprising sensing pressure in the pressure hose and the control is automatically activated responsive to sensed pressure.

14. The method of generating an emergency alarm in a personal alert safety system of claim 8 wherein the housing is adapted to receive an activation key operatively associated with the control and wherein the control is activated responsive to removal of the activation key.
