Abstract

Method, system and device useful with conventional personal computers respond automatically to an identified alarm sound by sending a notification signal via the Internet only when a special sound monitoring program is active. Additionally, bedside detection of acoustic alarms is combined with enhanced waking devices to insure the waking of a child or hearing impaired person in response to an emergency. Home safety and security are provided using a bedside unit to monitor audible safety and security alarms and send notification signals to the appropriate communication site. A health monitoring method and system utilizes the bedside device to monitor breathing patterns and other health measuring signals and communicate these patterns and signals to a medical monitoring station.

Claims

1. A method for monitoring health indicating parameters of an individual using a bedside unit, the method comprising:

operating a bedside monitoring unit having a microphone, a microprocessor, a memory having a signal signature of a health indicating parameter stored therein, and a communications port;

by operating the bedside unit, detecting sounds comprising health indicating parameters received by the microphone of the bedside unit and converting the sounds to a real time digital pattern representing the sounds;

using the microprocessor and a digital acoustic signature recognition technology, comparing the real time digital pattern to the signal signature stored in the memory, and determining if detected sound represents health indicating parameters, wherein the digital acoustic signature recognition technology comprises a technique selected from the group consisting of matched filtering, cross correlation, and neural networking; and

using the communications port of the operating bedside unit, relaying the health indicating parameters to a medical monitoring service.

2. The method of claim 1 wherein the unit further includes a switch for controlling supply of power to a waking device, and said method further comprises operating the bedside unit to detect from sounds received by the microphone of the bedside unit when the sounds represent a smoke detector alarm and in response thereto switching on supply of power to the waking device.

3. The method of claim 1 wherein the health indicating parameters comprise breathing-related parameters.

4. The method of claim 3 wherein the breathing-related parameters are selected from the group consisting of breathing rate, breathing sound frequency spectrum, snoring and coughing.

5. The method of claim 1 wherein the health indicating parameters comprise acoustic signals from a cardiac measuring device.

6. The method of claim 1 wherein the communications port is a wireless communications port.

7. The method of claim 1 further comprising communicating from the health monitoring service to at least one of a designated care giver and local emergency personnel.

8. The method of claim 1 wherein the bedside unit further comprises a receiver for receiving a signal from an electro-acoustic measuring device wherein the electro-acoustic measuring device is designed and positioned to detect a health indicating parameter of the person monitored, and said method further comprises using the bedside unit to relay the signals from the electro-acoustic measuring device to a medical monitoring service.

9. The method of claim 8 wherein the electro-acoustic measuring device is selected from the group consisting of load sensors, wireless chest strap heart monitors, accelerometers, pulse sensors and pulse oximeters.

10. The method of claim 9 wherein the wireless chest strap monitor is designed to sense and transmit health indicating parameters selected from the group consisting of beat-to-beat R-wave intervals, QRS duration, chest movement and activity.

11. The method of claim 8 wherein the electro-acoustic measuring device comprises a strain gage positioned to measure the person'"'"'s chest movement.

12. The method of claim 8 wherein the electro-acoustic measuring device comprises an accelerometer positioned to measure the person'"'"'s activity.

13. A health monitor comprising:

a bedside monitoring unit including a microphone, microprocessor, and a communications port; and

a monitoring program stored within the microprocessor, including;

first instructional signals for determining when sound received through the microphone of the bedside unit represents a health indicating parameter, the first instructional signals comprising a technique selected from the group consisting of matched filtering, cross correlation, and neural networking; and

second instructional signals for relaying the health indicating parameter to a medical monitoring service through the communications port.

14. The health monitor of claim 13 further comprising a receiver for receiving a signal from a measuring device, and the monitoring program further comprises instructional signals for relaying signals from the measuring device to a medical monitoring service.

15.

16. The health monitor of claim 15 further comprising battery backup power for operation of the monitoring unit including powering the waking device.

17. The health monitor of claim 13 wherein the communications port is a wireless communications port.

18. A home health monitoring system comprising:

a device for measuring a health indicating parameter and generating a signal in response; and
