Abstract
A system and a method for improving a person'"'"'s sleep is disclosed, wherein the system comprises a bedding layer comprising a plurality of individually controllable thermally adjustable zones, a plurality of temperature sensors, wherein at least one temperature sensor per thermally adjustable zone is dispersed throughout the bedding layer, and means for controlling the heating power of each thermally adjustable zone, wherein the system is configured for controlling the heating power of the thermally adjustable zones in which the body presence is detected. The method comprises detecting the position of the body of the person on or underneath a bedding layer, and controlling the heating and cooling of each individual thermally adjustable zone in which the body presence is detected. A computer program product for carrying out the method is also disclosed.

A system for improving a person'"'"'s sleep, the system comprises a bedding layer comprising a plurality of thermally adjustable zones, a plurality of temperature sensors, wherein at least one temperature sensor per thermally adjustable zone is dispersed throughout the bedding layer, the temperature of each thermally adjustable zone can be controlled separately, and the system comprises means for controlling the heating or cooling power of each of said thermally adjustable zone, wherein the system is configured such that the position of the body of the person on or underneath the bedding layer can be detected by using the plurality of temperature sensors for identifying those thermally adjustable zones selected from the group of zones, where the temperature increases faster than in other zones, where the power needed for maintaining a set temperature is less, and where the actual temperature is above the set temperature, any one of the temperature, the heating rate and the cooling rate of each individual thermally adjustable zone can be controlled, and wherein the system is configured to automatically switch-off the heating after a preset period of time after the person got out of the bed.

18. A computer program product to execute a method for improving a person'"'"'s sleep, the method comprising:
-
detecting the position of the body of the person on or underneath a bedding layer, the bedding layer comprising a plurality of individually thermally adjustable zones and a plurality of temperature sensors, wherein at least one temperature sensor per thermally adjustable zone is dispersed throughout the bedding layer, wherein any one of the group consisting of the temperature, the heating rate and the cooling rate of each thermally adjustable zone can be controlled separately, controlling any one of the group consisting of the temperature, the heating rate and the cooling rate of each individual thermally adjustable zone of the bedding layer such that the temperature of the thermally adjustable zones are adjusted to a preset temperature, and adjusting the temperature of each individual thermally adjustable zone of the bedding layer such that the temperature of each individual thermally adjustable zone in which areas a part of the person'"'"'s body is present is maintained at a preset temperature, wherein the computer program includes an algorithm for detecting the position of a body on or underneath a bedding layer, the algorithm uses the knowledge of at least one of the group consisting of the set temperature, the room temperature, the human metabolic rate, skin temperature, and at least one of the difference in temperature change with or without a person present, the difference in power consumption for maintaining a set temperature with or without a person present, and the actual temperature, with respect to each one of the plurality of temperature sensors.
