Abstract
A method and system of physiological monitoring, includes measuring a quantity relating to a first subject with a first sensor positioned in or in proximity of the first subject and configured to provide a first signal, measuring a quantity relating to a second subject with a second sensor positioned in or in proximity of the second subject and configured to provide a second signal, and analyzing the first and the second signal and the interrelation of the first and second signal in order to determine at least one event relating to the first and/or the second subject.
Claims16
A method of sleep monitoring, comprising:
- monitoring, using a first sensor positioned closer to a first subject than a second subject, a first sleep parameter relating to the first subject, the first sensor configured to output a first signal, the first signal at least partially based on the first sleep parameter;
- monitoring, using a second sensor positioned closer to the second subject than the first subject, a second sleep parameter relating to the second subject, the second sensor configured to output a second signal, the second signal at least partially based on the second sleep parameter;
- identifying a movement event in the first signal;
- identifying the movement event in the second signal;
- comparing, by a control unit, the first signal to the second signal, wherein comparing the first signal to the second signal comprises:
- determining a first signal amplitude associated with the movement event in the first signal and a second signal amplitude associated with the movement event in the second signal;
- comparing the first signal amplitude to the second signal amplitude, and determining a time delay between the movement event detected by the first sensor and the movement event detected by the second sensor;
- and
- based at least partially on comparing the first signal amplitude to the second signal amplitude, and determining the time delay between the movement event detected by the first sensor and the movement event detected by the second sensor, assigning the movement event to a movement of one of the first or second subjects.
A system for monitoring sleep, comprising:
- a first sensor positioned at a first location on or in a bed and proximate to a first subject, the first sensor configured to:
- monitor a first sleep parameter relating to the first subject;
- and
- output a first signal, the first signal at least partially based on the first sleep parameter;
- a second sensor positioned at a second location on the bed and proximate to a second subject, the second sensor configured to:
- monitor a second sleep parameter relating to the second subject;
- and
- output a second signal, the second signal at least partially based on the second sleep parameter;
- and
- a control unit operably connected to the first and second sensors, and configured to:
- identify a movement event in the first signal;
- identify the movement event in the second signal;
- compare the first signal to the second signal by:
- determining a first signal amplitude associated with the event in the first signal and a second signal amplitude associated with the event in the second signal;
- comparing the first signal amplitude to the second signal amplitude, and determining a time delay between the movement event detected by the first sensor and the movement event detected by the second sensor;
- and
- based at least partially on comparing the first signal amplitude to the second signal amplitude, and determining the time delay between the movement event detected by the first sensor and the movement event detected by the second sensor, assigning the event to a movement of one of the first or second subjects.
