Human biovibrations method
View Patent ↗This invention relates to the detection of human biovibrations using a digital signal processing (DSP) actigraph worn by the individual, and in at least one method using any noise existing in the signals. Human biovibrations result from the human body having reverberations and oscillations from bodily functioning. The DSP actigraph has been shown to be able to identify heart beat and breathing of an individual. The invention includes a method comprising: recording movement data of an individual that includes biovibrations data, determining when the movement data substantially falls within a predetermined threshold representative of death, and providing a notification. The invention in at least one embodiment includes a method comprising: monitoring activity counts for zero crossing mode, above threshold mode, and proportional integrative mode, providing a notification when all three activity counts are within a respective predetermined range for a period of time.
1. A method comprising:
monitoring activity counts for zero crossing mode, above threshold mode, and proportional integrative mode of an individual with an actigraph,
providing a notification when the activity counts for zero crossing mode, above threshold mode, and proportional integrative mode are within a respective predetermined range for a period of time.
2. The method according to claim 1 , further comprising:
providing medication to an individual being monitored in response to the notification.
3. The method according to claim 1 , wherein the period of time is at least 15 minutes.
4. The method according to claim 1 , wherein the predetermined range has a maximum of 90% of an average activity count over a preceding hour.
5. The method according to claim 4 , wherein the predetermined range has a minimum greater than 10% of the average activity count of the preceding hour.
6. The method according to claim 1 , wherein the predetermined range is above activity counts representative of sleep.
7. The method according to claim 6 , wherein when the predetermined range is reached, a patient being monitored is suffering pain.
8. The method according claim 6 , wherein when a duration and frequency of the activity counts are decreased in a period of time as compared to a preceding period of time, the notification includes an indication of a migraine.
9. The method according claim 1 , further comprising providing a migraine notification when a duration and frequency of the activity counts are decreased in a period of time as compared to a preceding period of time.
10. The method according to claim 1 , wherein the predetermined range has a minimum greater than 10% of an average activity count over a preceding hour.
11. The method according to claim 1 , further comprising analyzing an effectiveness of medication for relieving a migraine based on a reduction of fragmentation in sleep in at least one night following the migraine.
12. The method according to claim 1 , further comprising:
determining presumptive death when zero crossing mode is null for at least two minutes, and
determining definitive death when zero crossing mode is null for at least five minutes.
13. The method according to claim 1 , wherein the actigraph provides the notification.
14. A method comprising:
monitoring activity counts for zero crossing mode, above threshold mode, and proportional integrative mode of a patient with an actigraph,
determining the activity count levels for the patient when the patient is asleep, and
providing medication when at least two of a duration, a frequency and a level of at least two of the activity counts during a current sampling period are lower than the prior sampling period but above the activity counts associated with sleep for the patient being monitored.
15. The method according to claim 14 , wherein the actigraph determines the activity count.
16. The method according to claim 14 , wherein a processor determines the activity count.
17. A method comprising:
recording movement data of an individual that includes biovibrations data with an actigraph,
determining when the movement data substantially falls within a predetermined threshold representative of death, and
providing a notification.
18. The method according to claim 17 , further comprising:
providing a notification when oscillations of the movement data decrease over a period of time.
19. The method according to claim 17 , wherein the predetermined threshold is a baseline value.
20. The method according to claim 17 , wherein the actigraph determines when the movement data substantially falls and provides a notification.
