In some implementations, sensor data is obtained over a time period while a person is sleeping. The time period is divided into a series of intervals. Heart rate and changes in the heart rate are analyzed over the intervals. Based on the analysis of the heart rate changes, sleep stage labels are assigned to different portions of the time period. An indication of the assigned sleep stage labels is provided.

    Abstract: Apparatus for monitoring a clinical condition of a subject is described. At least one motion sensor detects motion of the subject and generates a sensed motion signal responsive to the sensed motion. A signal analyzer is adapted to determine a heartbeat-related signal from the sensed motion signal, to determine a first breathing-rate-related signal from the heartbeat-related signal, and to determine a second breathing-rate-related signal directly from the sensed motion signal. The signal analyzer determines the validity of the heartbeat-related signal by comparing the first breathing-rate-related signal with the second breathing-rate-related signal. Other applications are also described.

    Abstract: An alertness device includes: a respiration sensor that obtains respiratory data of a person; a calculation unit; a waveform generation unit that generates a respiratory interval (RI) waveform which is a transition in a predetermined time period of an RI which is an interval for one respiration; and a determination unit. The calculation unit calculates an average value of the RI and RrMSSDn in a predetermined time period. In a case where an average value of the subsequent RI is greater than an average value of the RI directly previous to the subsequent RI and in a case where the RrMSSDn of the subsequent RI is greater than a value which is obtained by multiplying the RrMSSDn of the previous RI by a constant ?, the determination unit determines on the basis of values calculated by the calculation unit that the person is in a state of low alertness.
