Sleep Number has filed a patent for a system that controls the temperature of a bed. The system includes a bed with thermal modules on each side and a computer system that receives data about the bed, such as temperature and pressure. Based on this data, the system can activate a heat crosstalk mitigation routine on the unoccupied side of the bed to maintain optimal temperature control.

A recently filed patent (Publication Number: US20230276948A1) describes a system for temperature control of a bed. The system includes a bed with a mattress, a first thermal module on one side of the bed, and a second thermal module on the other side of the bed. A computer system is in communication with the bed and is configured to receive data about the bed, such as temperature data, pressure data, heat routine activation data, and cool routine activation data.

Based on the received data, the computer system can determine if a heat routine is activated on one side of the bed and if the other side of the bed is unoccupied. In such cases, the computer system generates instructions that cause the second thermal module to activate a heat crosstalk mitigation routine on the unoccupied side of the bed. This helps prevent heat transfer between the two sides of the bed.

The computer system can also receive user input from a user device indicating an adjustment to the microclimate of the second side of the bed. Based on this input, the system generates instructions to deactivate the heat crosstalk mitigation routine and make the desired adjustment to the microclimate.

The system includes temperature sensors and pressure sensors on both sides of the bed to gather data. The computer system can receive data from these sensors, as well as from ambient temperature sensors in the surrounding environment. It can also receive data from a pressure sensor to determine if the second side of the bed is occupied by a user.

Additionally, the computer system can determine the fan speed of the second thermal module based on the heat level of the first thermal module. It can generate instructions to activate the fan at a high speed for high heat levels and at a low speed for low heat levels.

Overall, this patent describes a system that uses data from various sensors and user input to control the temperature of a bed. It aims to provide personalized comfort by mitigating heat transfer between different sides of the bed and allowing users to adjust the microclimate to their preferences.
