System and method for determining sleep and sleep stages of a person
First Claim
1. A system for determining sleep, a sleep stage, sleep stage transition, and/or a sleep event of a person, comprising:
- a wearable device configured for detecting and recording a heart rate of the person and configured for detecting and recording a movement of a part of the body of the person, wherein the movement is caused by a skeletal muscle of the body;
an analysis device configured for classifying the recorded heart rate of the person into at least one heart rate class and at least one heart rate variability class, configured for classifying the recorded movement into a movement class comprising a large movement (LM), a small movement (SM) or a twitch (TM), based on a calculated intensity and/or duration of each movement, wherein the analysis device is capable of classifying the movement into any of the LM, SM, and TM, and configured for determining sleep, a sleep stage, a sleep stage transition and/or a sleep event of the person based at least partially on the at least one heart rate class, the at least one heart rate variability class, and the movement class; and
a data connection configured for communicating data representing the recorded heart rate and the recorded movement from the wearable recording device to the analysis device, and wherein the analysis device is configured for classifying the recorded movement into the movement class based on the calculated intensity level of 1 to 2 counts per second, 3 to 5 counts per second, or 6 to 10 counts per second.

Abstract
The present invention relates to a system and method for determining sleep, sleep stage and/or sleep stage transition of a person, including heart rate detecting means configured for detecting a heart rate of the person, movement detecting means configured for detecting a movement of a part of the body of the person, where the detected movement is caused by a skeletal muscle of the body, recording means configured for recording the detected heart rate and the detected movement of the part of the body, heart rate classifying means configured for classifying the recorded heart rate of the person into at least one heart rate class at least one heart rate variability class, movement classifying means configured for classifying the recorded movement into at least one movement class, and determining means configured for determining sleep, a sleep stage, a sleep stage transition and/or a sleep event of the person based at least partially on the at least one heart rate class and the at least one movement class.

12. A method for determining sleep, a sleep stage, a sleep stage transition, and/or a sleep event of a person, the method comprising:
-
detecting a heart rate of the person; recording the detected heart rate; detecting a movement of a part of the body of the person, wherein the movement is caused by a skeletal muscle of the body; recording the detected movement; classifying the recorded heart rate of the person into at least one heart rate class and at least one heart rate variability class; classifying the recorded movement into a movement class comprising a large movement (LM), a small movement (SM), or a twitch movement (TM), based on a calculated intensity and/or the calculated duration of each movement, wherein the classifying includes classifying the movement into any of the LM, SM, and TM; and determining sleep, a sleep stage, a sleep stage transition and/or a sleep event of the person based at least partially on the at least one heart rate class, the at least one heart rate variability class, and the movement class, and wherein classifying the recorded movement into the movement class is based on the calculated intensity level of 1 to 2 counts per second, 3 to 5 counts per second, or 6 to 10 counts per second. - View Dependent Claims (13, 14, 15)
