Abstract
Disclosed herein are methods and devices for monitoring a subject at rest. One such device comprises a sensing unit having a fluid-filled bladder configured to be placed under a substrate on which the subject lays and a sensor in fluid communication with the bladder. The sensor is configured to sense pressure variations within the bladder generated by a heart beat, respiration and body weight of the subject and to generate signals indicative of the pressure variations. A processor is configured to receive the signals and to determine and generate output indicative of the subject'"'"'s heart beat and respiration and presence on the substrate. An external device is configured to display one or more of the output.

2. A sleep system comprising:
-
a sensor configured to be positioned with respect to a mattress, to sense a user, and to generate a sensor signal in response to sensing the user; and a controller in data communication with the sensor for receiving the sensor signal from the sensor, wherein the controller is configured to; determine a user heart rate of the user based on the sensor signal, determine a user respiration rate of the user based on the sensor signal, determine a total time in bed of the user based on the sensor signal, calculate a sleep score as a function of at least the determined user heart rate, the determined user respiration rate, and the determined total time in bed, wherein the sleep score is a score indicative of quality of a night'"'"'s sleep by the user, and transmit a sleep-score signal that is configured such that the sleep score is displayable on a display screen. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method comprising:
-
sensing, via a sensor positioned under a user lying on a mattress, a user heart rate of the user; sensing, via the sensor, a user respiration rate of the user lying on the mattress; sensing, via the sensor, a total time in bed of the user lying on the mattress; calculating a sleep score as a function of at least the sensed user heart rate, the sensed user respiration rate, and the sensed total time in bed, wherein the sleep score is a score indicative of quality of a night'"'"'s sleep; transmitting a sleep score-signal to a display screen; and displaying the sleep score to the user.

21. A sleep system comprising:
-
a means for sensing a user positioned on a mattress and generating a sensor signal in response to sensing the user; and a controller in data communication with the sensor for receiving the sensor signal from the sensor, wherein the controller is configured to; determine a user heart rate of the user based on the sensor signal, determine a user respiration rate of the user based on the sensor signal, determine a total time in bed of the user based on the sensor signal, calculate a sleep score as a function of at least the determined user heart rate, the determined user respiration rate, and the determined total time in bed, wherein the sleep score is a score indicative of quality of a night'"'"'s sleep by the user, and transmit a sleep-score signal that is configured such that the sleep score is displayable on a display screen.
