Abstract

Introduced are a bed device system and methods for: gathering human biological signals, such as heart rate, breathing rate, or temperature; analyzing the gathered human biological signals; and controlling the bed device system, e.g., a temperature of the bed device, based on the analysis.

Claims

1. A bed system for measuring a biological signal associated with a user and an environment property, and based on said biological signal and said environment property automatically adjusting a temperature of a mattress, said bed system comprising:

a bed device configured to receive an instruction to heat said mattress to a specified temperature, said bed device comprising a mattress cover, said mattress cover further comprising;

a sensor strip, wherein said sensor strip comprises a user sensor configured to measure said biological signal associated with said user, wherein said biological signal comprises a heart rate associated with said user, and a breathing rate associated with said user;

a temperature regulating layer configured to adjust said temperature of said mattress;

an environment sensor, configured to measure said environment property, wherein said environment property comprises a current time, a temperature, a humidity, a light intensity, or a sound intensity;

a processor communicatively coupled to said bed device and said environment sensor, said processor configured to;

determine, based on said biological signal associated with said user and said environment property, a change in a sleep state associated with said user;

based on said biological signal associated with said user, determine said sleep state associated with said user, and a confidence threshold associated with said sleep state;

adjust a likelihood that said user is asleep based on said environment property and said confidence threshold associated with said sleep state; and

when said likelihood that said user is asleep is above a specified threshold, send a control signal, said control signal comprising an instruction to said bed device to adjust a temperature associated with said bed device to an average temperature associated with said current time and said user.
