US20190090785

1. A method for the detection of the posture of a body, especially while sleeping, the method comprising the steps of: (5) (4)

providing a bedding;

projection of a pattern of electromagnetic radiation at least on a part of said bedding;

detection of the reflection of the projected pattern caused by a body on said bedding;

comparing the reflection pattern with a reflection pattern representing typical body postures.

2. The method according to claim 1, wherein during the comparison of the reflected pattern with a pattern representing typical body postures the subject's body is virtually segmented into at least two major parts: Upper body left and right, middle part left and right, bottom part left and right, of which the sum of the present intensity is computed. (0)

3. The method according to claim 1, wherein the light source for the projection of the pattern of electromagnetic radiation is an IR-LED laser. (0)

4. The method according to claim 1, wherein the projection of the pattern of electromagnetic radiation on said bedding is performed in an intermitted and/or modulated way. (0)

5. The method according to claim 1, wherein the detection of the reflection of the pattern of electromagnetic radiation is a low resolution sensor array. (0)

6. The method according to claim 1, wherein additional information are considered for the determination of the body posture. (2) (0)

7. The method according to claim 6, wherein acoustical information and/or information on the breathing amplitude are used for the determination of the body posture. (1) (0)

9. The method according to claim 6, wherein acoustical information is retrieved via at least two microphones positioned on both sides of the bedding. (1) (0)

12. An apparatus for the detection of postures of a body on a bedding, the apparatus comprising: (2) (3)

A projector for the projection of pattern of electromagnetic waves on said bedding;

A detector for the detection of reflection of the pattern projected by said projector;

A data processing means connected to the detector, said data processing means being capable to compare actual reflection detected by the detector with stored reflection patterns representing typical body postures.

13. The apparatus according to claim 12, further comprising at least one microphone connected to said data processing means. (0)

14. The apparatus according to claim 12, wherein the projector is an IR-LED-laser. (0)
