1. A computer-implemented method for changing a state of a wearable device for an infant, comprising:
- at the wearable device, detecting motion of the wearable device when a motion sensor included in the wearable device outputs a voltage that exceeds a threshold voltage corresponding to a threshold motion magnitude of the wearable device;
in response to the detecting of the motion, transitioning the wearable device from a low-power mode into a test mode by waking a processor included in the wearable device, arming a proximity sensor included in the wearable device, and arming a temperature sensor included in the wearable device;
in the test mode;
detecting a proximity of the wearable device to a surface with the proximity sensor;
detecting a temperature of the surface with the temperature sensor;
determining, at the processor, that the surface is human skin of an infant based on the temperature of the surface; and
in response to determining that the surface is the human skin of the infant, transitioning from the test mode into an active mode by activating a heart rate sensor included in the wearable device and activating a wireless communication module included in the wearable device; and
in the active mode;
receiving, at the processor, data signals from the heart rate sensor;
determining a heart rate value corresponding to the data signals; and
acquiring raw data from one or more of the motion sensor, the proximity sensor, and the temperature sensor;
wirelessly broadcasting, via the wireless communication module, the heart rate value and the acquired raw data to a base station such that the base station thereby determines a wake time for the infant.

Abstract
One variation of a method for changing a state of a wearable device includes: in response to detected motion of the wearable device, transitioning from a low-power mode into a test mode; in the test mode, detecting a proximity of a surface to the wearable device, detecting a temperature of the surface, and based on a temperature of the surface correlated to a human skin temperature, transitioning from the test mode into an active mode; and, in the active mode sampling a heart rate sensor arranged within the wearable device and wirelessly broadcasting a value corresponding to an output of the heart rate sensor.
