Abstract

A system can include a bed having a mattress, a sensor, and the data processing device. The sensor is configured to sense a feature of the mattress and transmit readings to a data processing device. The data processing device includes a processor and is configured to receive the readings from the sensor and determine if the readings i) indicate a user presence on the mattress and ii) indicate the user intends to sleep. The data processing device is configured to transmit a command to a peripheral controller responsive to determining that the readings i) indicate user presence on the mattress and ii) indicate the user intends to sleep.

First claim

What is claimed is:

1. A system comprising:
a mattress;
a sensor configured to:
sense a feature of the mattress; and
transmit readings to a data processing device; and

the data processing device comprising a processor and configured to:
receive the readings from the sensor;
determine if the readings i) indicate a user presence on the mattress and ii) indicate the user intends to sleep by comparing the user presence on the mattress with time windows of expected user going to bed events in a model of the user's sleep; and
responsive to determining that the readings i) indicate user presence on the mattress and ii) indicate the user intends to sleep, transmit a command to a peripheral controller to modify the state of a peripheral device.

2. The system of claim 1 , wherein the data processing device is further configured to:
responsive to determining that the readings i) indicate user presence on the mattress and ii) indicate the user intends to sleep, transmit a command to a user interface device.

3. The system of claim 1 , wherein:
the mattress is an air mattress having an air chamber;
the sensor is a pressure sensor in fluid communication with the air chamber; and
the feature of the mattress is air pressure.

4. The system of claim 1 , the system further comprising:
the peripheral controller configured to:
receive the command from the data processing device; and
responsive to receiving the command, modify a state of the peripheral device according to the command.

5. The system of claim 4 , wherein the command includes instructions to at least one of the group consisting of turning the peripheral device on, turning the peripheral device off, dimming the peripheral device, and changing the temperature of the peripheral device.

6. The system of claim 1 , wherein:
the data processing device is further configured to:
store the reading from the sensor; and
generate, based on the stored readings from the sensor, a model of the user's sleep behavior; and

to determine if the readings ii) indicate the user intends to sleep, the data processing device is further configured to compare some of the readings from the sensor with the model of the user's sleep behavior.

7. The system of claim 6 , wherein:
the data processing device is further configured to access historical sensor data from a cloud service; and
to generate, based on the stored readings from the sensor, a model of the user's sleep behavior, the data processing device is further configured combine the historical sensor data with the stored readings from the sensor.

8. The system of claim 6 , wherein:
the data processing device is further configured to:
determine that, based on the model of the user's sleep behavior, the user is likely to sleep within a threshold time in the future; and
responsive to determining that the user is likely to sleep within a threshold time in the future, transmit a second command to the peripheral controller;

and wherein the peripheral controller is further configured to:
receive the second command from the data processing device; and
responsive to receiving the second command, modify a state of the peripheral device according to the second command.

9. The system of claim 8 , wherein the command comprises instructions to turn off the peripheral device and the second command comprises instructions to turn on the peripheral device.

10. The system of claim 1 , wherein the data processing device is further configured to:
responsive to determining that the readings do not i) indicate user presence on the mattress and ii) indicate the user intends to sleep, not transmitting the command to the peripheral controller.

11. The system of claim 1 , wherein the data processing device is further configured to:
responsive to determining that the readings i) do indicate user presence on the mattress and ii) do not indicate the user intends to sleep for at least a threshold period of time, not transmitting the command to the peripheral controller.

12. The system of claim 1 , wherein:
the data processing device is further configured to:
identify a first time range during which the user would be expected to sleep once presence of the user is detected on the mattress during the first time range;
transmit the command to the peripheral controller if the data processing device determines that the readings indicate user presence on the mattress during the first time range; and
not transmit the command to the peripheral controller if the data processing device determines that the readings indicate user presence on the mattress outside of the first time range.

13. A method performed by data processing apparatus, the method comprising:
receiving, from a sensor configured to sense a feature of a mattress, readings;
determining if the readings i) indicate a user presence on the mattress and ii) indicate the user intends to sleep by comparing the user presence on the mattress with time windows of expected user going to bed events in a model of the user's sleep; and
responsive to determining that the readings i) indicate user presence on the mattress and ii) indicate the user intends to sleep, transmitting a command to a peripheral controller to modify the state of a peripheral device.

14. The method of claim 13 , the method further comprising:
receiving, at the peripheral controller, the command; and
responsive to receiving the command, modifying a state of the peripheral device according to the command.

15. The method of claim 13 , the method further comprising:
storing the readings from the sensor; and
generating, based on the stored readings from the sensor, a model of the user's sleep behavior;
wherein determining if the readings i) indicate a user presence on the mattress and ii) indicate the user intends to sleep comprises comparing some of the readings from the sensor with the model of the user's sleep behavior.

16. The method of claim 15 , the method further comprising:
accessing historical sensor data from a cloud service; and
combining the historical sensor data with the stored readings from the sensor.

17. The method of claim 15 , the method further comprising:
determining that, based on the model of the user's sleep behavior, the user is likely to sleep within a threshold time in the future; and
responsive to determining that the user is likely to sleep within a threshold time in the future, transmitting a second command to the peripheral controller, wherein the command comprises instructions to turn off the peripheral device and the second command comprises instructions to turn on the peripheral device.

18. The method of claim 15 , the method further comprising:
determining at a second time that the readings i) indicate a user presence on the mattress and ii) do not indicate the user intends to sleep; and
responsive to determining that the readings i) indicate a user presence on the mattress and ii) do not indicate the user intends to sleep, not transmitting a command to the peripheral controller.

19. A system comprising:
means for supporting a user on a mattress;
a sensor configured to:
sense a feature of the mattress; and
transmit readings to a data processing device; and

the data processing device comprising a processor and configured to:
receive the readings from the sensor;
determine if the readings i) indicate user presence on the mattress and ii) indicate the user intends to sleep by comparing the user presence on the mattress with a model of the user's sleep, wherein the
