Abstract

A mattress includes one or more sensors. The sensor(s) may be positioned on a sleep surface of the mattress; for example, at locations where an individual's thorax and/or legs would be positioned when the individual assumes a sleeping position on the sleep surface. The sensor(s) may be positioned adjacent to an edge of the mattress, on the sleep surface or on the edge. A processor may be associated with the sensor(s) of the mattress. The processor may process signals received from the sensor(s) to provide information about the mattress, an individual on the mattress, and/or an environment in which the mattress is located.

First claim

What is claimed:

1. A mattress, comprising:
a cushioning element including:
an upper surface with a head portion, an intermediate portion, and a foot portion, and
an outer periphery including ends and sides of the cushioning element;

rails adjacent to the sides of the cushioning element;
at least one thoracic sensor positioned adjacent to the upper surface of the head portion of the cushioning element or adjacent to the upper surface of the intermediate portion of the cushioning element;
at least one leg sensor positioned adjacent to the upper surface in the foot portion of the cushioning element; and
at least one edge sensor positioned within a receptacle of a rail of the rails, the receptacle positioned between the head portion and the foot portion of the cushioning element, and the receptacle positioned to open towards an outer top surface of the rail.

2. The mattress of claim 1 , wherein the at least one thoracic sensor monitors respiration, heart rate, and movement.

3. The mattress of claim 2 , wherein the at least one thoracic sensor further monitors temperature and humidity.

4. The mattress of claim 3 , wherein the at least one thoracic sensor comprises an inclinometer, an accelerometer, and a plurality of temperature/humidity sensors.

5. The mattress of claim 1 , wherein the at least one leg sensor monitors movement.

6. The mattress of claim 5 , wherein the at least one leg sensor further monitors temperature and humidity.

7. The mattress of claim 6 , wherein the at least one leg sensor comprises an accelerometer and a plurality of temperature/humidity sensors.

8. The mattress of claim 1 , wherein the at least one edge sensor monitors an environment in which the mattress is located.

9. The mattress of claim 1 , wherein the at least one edge sensor monitors movement.

10. The mattress of claim 9 , wherein the at least one edge sensor monitors movement and a room in which the mattress is located.

11. The mattress of claim 9 , wherein the at least one edge sensor further monitors temperature and humidity.

12. The mattress of claim 9 , wherein the at least one edge sensor comprises an accelerometer and a temperature/humidity sensor.

13. A mattress, comprising:
a cushioning element including:
an upper surface with a head portion, an intermediate portion, and a foot portion, and
an outer periphery including ends and sides of the cushioning element;

rails adjacent to the sides of the cushioning element;
at least one thoracic sensor that monitors movement, temperature, and humidity positioned adjacent to the upper surface of the head portion of the cushioning element or adjacent to the upper surface of the intermediate portion of the cushioning element;
at least one leg sensor that monitors movement positioned adjacent to the upper surface in the foot portion of the cushioning element; and
at least one edge sensor positioned within a receptacle of a rail of the rails, the receptacle positioned between the head portion and the foot portion of the cushioning element, and the receptacle positioned to open towards an outer top surface of the rail.

14. A method for monitoring use of a mattress, comprising:
monitoring metrics of an individual on the mattress including:
monitoring movement of the individual, a respiratory rate of the individual, and a heart rate of the individual at or adjacent to a head portion of the mattress;
monitoring movement of the individual at or adjacent to a foot portion of the mattress;
monitoring a presence of the individual in proximity to at least one side of the mattress via at least one edge sensor positioned within a side of the at least one side, the at least one edge sensor positioned in a receptacle of the side that is positioned to open towards an outer top surface of the side; and
monitoring an ambient environment at a periphery of the mattress; and

providing at least one metric regarding the individual on the mattress to a portable device.

15. The method of claim 14 , further comprising:
monitoring temperature and humidity at or adjacent to the head portion of the mattress and at or adjacent to the foot portion of the mattress.

16. The method of claim 14 , wherein monitoring the ambient environment comprises monitoring a temperature and a humidity of the ambient environment.

17. The method of claim 14 , further comprising:
detecting at least one of placement of the individual on the mattress and removal of the individual from the mattress.

18. The method of claim 14 , further comprising:
adjusting the mattress in response to data obtained from any of the foregoing acts of monitoring.

19. The method of claim 18 , wherein adjusting the mattress comprises adjusting an orientation of one or more portions of the mattress, adjusting ventilation of the mattress, and/or adjusting a temperature of the mattress.
