Using Active Ir Sensor To Monitor Sleep
In an implementation of the disclosed subject matter, a device may emit a first emission sequence of infrared radiation at a subject, and capture a first reflected sequence of infrared radiation reflected from the subject. The first emission sequence may be compared to the first reflected sequence, and, based on the comparison, a sequence of variations may be determined. The sequence of variations may be compared to signal pattern stored in a sleep profile for the subject. The subject may be determined to have exhibited sleep behavior based on the comparison of the sequence of variations to the signal pattern stored in the sleep profile. In response to determining the subject has exhibited sleep behavior, the device may capture a second reflected sequence of radiation reflected from the subject. A breathing rate of the subject and/or a heart rate of the subject may be determined based on the second reflected sequence.

- 1. A method for determining an occurrence of a sleep behavior or disorder, the method comprising:
receiving, from a radiation capture component of an electronic device, a first signal corresponding to a sequence of radiation reflected from a subject; filtering the first signal by reducing at least one energy peak of the reflected sequence of radiation to produce a second signal; determining a heart rate of the subject based on the second signal; determining an occurrence of a sleep behavior or disorder based on the heart rate; and in response to the occurrence of the sleep behavior or disorder, causing a notice about the occurrence of the sleep behavior or disorder to be provided.
- 11. A system for determining an occurrence of a sleep disorder, the system comprising:
a memory configured to store a first signal and a second signal; and a processor configured to:
receive, from a radiation capture component of an electronic device, a first signal corresponding to a sequence of radiation reflected from a subject;
filter the first signal by reducing at least one energy peak of the reflected sequence of radiation to produce a second signal;
determine a heart rate of the subject based on the second signal;
determine an occurrence of a sleep behavior or disorder based on the heart rate; and
in response to the occurrence of the sleep behavior or disorder, cause a notice about the occurrence of the sleep behavior or disorder to be provided.
