Abstract

Health-sensing and health-action devices and systems are generally described. The health-sensing device may include one or more of a sensor, a filter, and a transmitter. The sensor may be configured to sense when a user is likely to have fallen down and may include a sensor in the form of one or more microphone devices, accelerometers, and/or MEMs devices. The filter may be configured to evaluate a signal from the sensor and determine when a fall has occurred and analyze the magnitude of the fall. The transmitter may be arranged for initiating a transmission based on a signal from the filter. The health-action device may be configured for responding to a fall and may include one or more of a receiver, a processor, and a responder. A notifying element may also be included for interrupting the transmission when assistance is not needed.

Claims

1. A health-sensing device for placement on a user to monitor a likelihood of a fall by the user, the device comprising:

a sensor configured to;

sense a motion associated with the health-sensing device, and

generate a sensor signal indicative of the sensed motion;

a filter configured to;

receive the sensor signal,

determine when the received sensor signal indicates the likelihood of the fall by the user, and

generate a filter signal when the likelihood of the fall by the user is determined; and

a transmitter configured to;

receive the filter signal, and

generate a transmission responsive to the filter signal.

2. The device of claim 1, wherein the sensor comprises an accelerometer.

3. The device of claim 1, wherein to determine when the received sensor signal indicates the likelihood of the fall by the user, the filter is configured to compare the sensed motion from the received sensor signal to a range of threshold accelerations.

4. The device of claim 3, wherein the range of threshold accelerations comprises a preset response strategy relating to the threshold accelerations within the range.

5. The device of claim 1, further comprising a notifying element positioned on the health-sensing device, wherein the filter is configured to trigger the notifying element.

6. The device of claim 5, further comprising an actuatable element positioned on the health-sensing device and in communication with the filter, the actuatable element and filter being configured to interrupt the transmission.

7. The device of claim 5, further comprising an actuatable element positioned on the health-sensing device and in communication with the filter, the actuatable element and filter being configured to generate an overriding filter signal for transmission by the transmitter.

8. A method for a health-sensing device to monitor a likelihood of a fall by a user, the method comprising:

sensing a motion associated with the user to generate a sensor signal indicative of the sensed motion;

analyzing the sensor signal to determine when the sensed motion associated with the user identifies the likelihood of the fall by the user; and

initiating a transmission responsive to the analysis of the sensor signal.

9. The method of claim 8, wherein analyzing the sensor signal further comprises comparing the sensed motion from the sensor signal to a threshold for acceleration, and identifying the likelihood of the fall by the user when the sensed motion from the sensor signal exceeds the threshold for acceleration.

10. The method of claim 9, further comprising encoding the transmission with information indicating the sensed motion from the sensor signal exceeded the threshold for acceleration.

11. The method of claim 10, wherein the threshold acceleration comprises a high threshold, an intermediate threshold, and a low threshold.

12. The method of claim 11, further comprising driving a notifying element when the low threshold has been exceeded.

13. The method of claim 12, further comprising interrupting the transmission when the user is not in need of assistance.

14. The method of claim 11, wherein, when the intermediate threshold has been exceeded, initiating a transmission comprises transmitting a local signal.

15. The method of claim 11, wherein, when the high threshold has been exceeded, initiating a transmission comprises transmitting a signal off site.

16. A method for a health-action device to respond to a transmission of a likelihood of a fall from a health-sensing device, the method comprising:

receiving the transmission of a likelihood of a fall; and

performing a particular process.

17. The method of claim 16, wherein performing the particular process comprises sounding an alarm.

18. The method of claim 17, wherein sounding an alarm comprises selectively sounding an alarm indicative of a particular threshold acceleration that has been exceeded.

19. The method of claim 16, wherein performing the particular process comprises activating a notifying light source.

20. The method of claim 16, wherein performing the particular process comprises activating a display on a computer screen.

21. The method of claim 20, wherein activating a display comprises selectively displaying a notification indicative of a particular threshold acceleration that has been exceeded.

22. A health-action device for responding to an indicator of a likelihood of a fall by a user, the device comprising:

a receiver configured to receive the indicator of the likelihood of the fall by the user and generate a receiver signal;

a processor adapted to receive the receiver signal and configured to interpret the receiver signal to generate a processor signal; and

a responder adapted to receive the processor signal and configured to execute an action responsive to the processor signal, wherein the processor signal is indicative of the likelihood of the fall by the user.

23. The device of claim 22, wherein the action comprises sending a signal indicating that the user is in need of assistance.

24. The device of claim 23, wherein the responder comprises an audio alarm and sending a signal comprises sounding the audio alarm.

25. The device of claim 23, wherein the responder comprises a visual display on a computer monitor and sending a signal includes activating an alert on the display.
