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.

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.

22. The system of claim 1,

wherein, to compare the user presence on the mattress with a model of the user'"'"'s sleep,

the data processing device is further configured to:

determine a time that the readings indicate a user presence in on the mattress;

compare the time with the data indicative of a sleep schedule; and

determine if the time matches one of the time-windows of likely sleep of the sleep schedule.

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:
