Abstract

A method and system that allows healthcare providers, hospitals, skilled nursing facilities and other persons to monitor disabled, elderly or other high-risk individuals to prevent or reduce falls and/or mitigate the impact of a fall by delivering automated notification of “at risk” behavior and falls by such an individual being monitored where assistance is required.

Claims

1. A method for detecting when a monitored individual or any part of the monitored individual has crossed outside of a designated electronic perimeter, said method comprising the steps of:

(a) electronically calibrating virtual safety rails defining a designated electronic perimeter within an area of a room;

(b) configuring one or more 3D camera, motion and sound sensors to recognize a specific individual using one or more biometric identifiers of the individual in order to monitor movements of the specific individual;

(c) electronically receiving a continuous video feed by a computerized monitoring system from the one or more 3D camera, motion and sound sensors located in the room; and

(d) electronically alerting a computerized communication system when the computerized monitoring system detects that the specific individual located in the room or any part of the specific individual has crossed over the designated electronic perimeter based on 3D information from the continuous video feed received from the one or more 3D camera, motion and sound sensors.

2. The method for detecting of claim 1 wherein the one or more biometric identifiers include distance between points on a body of the specific individual.

3. The method for detecting of claim 1 further comprising the step of electronically issuing an audible message to the individual by the computerized communication system to inform the individual that they have crossed the designated electronic perimeter.

4. The method for detecting of claim 1 further comprising the step of generating an alert on a central video monitoring system if the individual fails to return within the designated electronic perimeter within a predetermined period of time after first issuing an audible message to the individual to return within the electronic perimeter of the virtual safety rails.

5. The method for detecting of claim 1 further comprising the step of notifying a designated person associated with the individual that the individual did not return within the designated electronic perimeter.

6. The method of detecting of claim 2 wherein the computerized monitoring system detects that the designated electronic perimeter has been crossed by the specific individual by tracking skeletal points on the body of the specific individual in real time from the continuous video feed received from the one or more with 3D camera, motion, and sound sensors.

7. A method for detecting when a monitored individual or any part of the monitored individual has crossed outside of a designated electronic perimeter, said method comprising the steps of:

(a) providing one or more 3D camera, motion and sound sensors within a room occupied by a specific individual to be monitored;

(b) configuring the one or more sensors to recognize one or more biometric identifiers of the specific individual in order to monitor movements of only the specific individual;

(c) electronically calibrating virtual safety rails defining a designated electronic perimeter within an area of the room;

(d) electronically forwarding a continuous video feed to a remote computerized monitoring system by the one or more sensors; and

(e) electronically alerting a computerized communication system when the remote computerized monitoring system detects that the specific individual or any part of the specific individual has crossed over the designated electronic perimeter based on 3D information from the continuous video feed received from the one or more 3D camera, motion and sound sensors.

8. The method for detecting of claim 7 further comprising the step of updating a database in communication with the remote computerized monitoring system regarding the detection of the individual or a part of the individual crossing over the designated electronic perimeter.

9. The method for detecting of claim 7 further comprising the step of notifying a previously designated contact by an electronic message informing the previously designated contact of the detected designated electronic perimeter crossing.

10. The method for detecting of claim 7 wherein no electronic alert is provided in step (e) if one or more other persons are detected to be in the room at the time the individual or a part of the individual crosses outside of the designated electronic perimeter though the remote computerized monitoring system continues to receive the continuous video feed from the one or more 3D camera, motion and sound sensors.

11. The method for detecting of claim 7 further comprising the step of continuing to send the video feed from the one or more with 3D camera, motion, and sound sensors to the remote computerized monitoring system after it has been determined that the individual or a part of the individual has crossed outside of the designated electronic perimeter.

12. The method for detecting of claim 7 further comprising the step of electronically issuing an audible message to the individual by the computerized communication system to inform the individual that they have crossed the designated electronic perimeter.

13. The method for detecting of claim 12 wherein the audible message is a pre-recorded message.

14. The method for detecting of claim 13 wherein the pre-recorded message contains the voice of a caregiver associated with the individual.

15. The method for detecting of claim 13, wherein the pre-recorded message advises the individual to return within the designated electronic perimeter defined by the virtual safety rails.

16. The method for detecting of claim 7 further comprising the step of generating an alert on a central video monitoring system if the individual fails to return within the designated electronic perimeter within a predetermined period of time after first issuing an audible message to the individual to return within the electronic perimeter of the virtual safety rails.

17. The method for detecting of claim 16 wherein the alert is an audible alert or a visual alert.

18. The method for detecting of claim 15 further comprising the step of notifying a designated person associated with the individual that the individual did not return within the designated electronic perimeter.

19. The method for detecting of claim 7 wherein the one or more biometric identifiers include distance between points on a body of the specific individual.

20. A method for detecting when a monitored individual or any part of the monitored individual has crossed outside of a designated electronic perimeter, said method comprising the steps of:

(a) providing one or more 3D camera, motion and sound sensors within a room occupied by a specific individual to be monitored;

(b) configuring the one or more sensors to recognize one or more biometric identifiers of the specific individual in order to monitor movements of only the specific individual;

(c) electronically calibrating virtual safety rails defining a designated electronic perimeter within an area of the room;

(d) electronically forwarding a continuous video feed to a remote computerized monitoring system by the one or more sensors; and

(e) electronically alerting a computerized communication system when the remote computerized monitoring system detects that the specific individual or any part of the specific individual has crossed over the designated electronic perimeter by tracking skeletal points on a body of the specific individual in real time from 3D information of the continuous video feed received from the one or more 3D camera, motion and sound sensors.
