Abstract

Provided is a system, method and device for determining one or more physiological parameters of a person.

Claims

1. A method of monitoring physiological and motion data of a person, the method comprising:

collecting physiological waveform data of a person comprising at lease one first signal;

collecting motion waveform form data of the person comprising at least one second signal;

using one of the first and second signals as a primary data and the other of the first and second signals as secondary data; and

using the secondary data to determine a filter response of the primary data.

2. The method according to claim 1, further comprising storing the primary and secondary data in a memory.

3. The method according to claim 1, further comprising transmitting the data wirelessly.

4. The method according to claim 1, further comprising transmitting the data by wire.

5. The method according to claim 1, further comprising transmitting the data by optical means or magnetic means.

6. The method according to claim 1, further comprising producing a plurality of sets of primary data and each set of data is filtered a first way is the secondary data is below a threshold and filtered a second way if the secondary data is above a threshold.

7. The method according to claim 6, wherein the threshold condition is satisfied by a combination of two or more sets of data.

8. The method according to claim 6, further comprising outputting the sets of data if the threshold condition is not satisfied during collection of the set of data and if the threshold condition is satisfied during collection of the set of data filtering the data and outputting the filtered data.

9. The method according to claim 6, wherein the threshold comprises one or more selected from the group of:

if the person'"'"'s heart rate is above (or below) a threshold, if the person is lying down (or sitting), if the ambient temperature is above (or below) a threshold, if humidity is above (or below) a threshold, if wind speed is above (or below) a threshold, if air pressure is above (or below) a threshold, if altitude is above (or below) a threshold, if vehicle speed is above (or below) a threshold, if water depth is above (or below) a threshold, if body temperature is above (or below) a threshold, if respiration rate is above (or below) a threshold, if GPS location of the person satisfies predetermined criteria, within predetermined time windows, receiving a user input; and

a signal to noise ratio (SNR) of the ECG waveform below a threshold.

10. The method according to claim 1, wherein the second signal comprises at least one of activity, skin resistance, signal noise level, amplitude, respiration, heart rate, humidity, or temperature.

11. The method according to claim 6, wherein the physiological waveform data comprises breathing waveform data.

12. The method according to claim 6, wherein the physiological waveform data comprises ECG waveform data.

13. A method of monitoring the physiological and motion data of a person, comprising:

collecting physiological waveform data of a person;

collecting motion waveform form data of the person;

setting an upper threshold and a lower threshold; and

if either the lower threshold or upper threshold are exceeded by the physiological waveform data or the motion waveform data, transmitting or logging the occurrence.

14. A method of monitoring the physiological and motion data of a person, comprising:

collecting physiological waveform data of a person comprising at lease one first signal;

collecting motion waveform form data of the person comprising at least one second signal;

setting one of the first and second signals as the primary signal and the other of the first and second signals as the secondary signal; and

using the secondary signal to remove artifacts and noise from the primary signal.
