Using active ir sensor to monitor sleep

Abstract

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.   
     
     
         2 . The method of  claim 1 , further comprising:
 receiving, from a sensor, information about a temperature in vicinity of the subject.   
     
     
         3 . The method of  claim 2 , wherein the first signal is filtered based on the temperature. 
     
     
         4 . The method of  claim 1 , wherein the notice is provided to a mobile device of a user separate from the subject. 
     
     
         5 . The method of  claim 4 , wherein the subject is a juvenile and the user is an adult. 
     
     
         6 . The method of  claim 4 , further comprising providing an alert to a healthcare provider or an emergency responder. 
     
     
         7 . The method of  claim 1 , wherein the notice is provided via the electronic device. 
     
     
         8 . The method of  claim 1 , further comprising:
 determining a sleep stage of the subject based upon the first signal; and   storing a record of the first signal and the determined sleep behavior or disorder in a sleep profile of the subject.   
     
     
         9 . The method of  claim 8 , further comprising:
 storing a record of the heart rate and/or the second signal in the sleep profile.   
     
     
         10 . The method of  claim 1 , wherein the notice is provided to a home monitoring hub. 
     
     
         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. 
   
     
     
         12 . The system of  claim 11 , the processor further configured to:
 receive, from a sensor, information about a temperature in vicinity of the subject.   
     
     
         13 . The system of  claim 12 , wherein the first signal is filtered based on the temperature. 
     
     
         14 . The system of  claim 12 , further comprising the sensor. 
     
     
         15 . The system of  claim 11 , wherein the notice is provided to a mobile device of a user separate from the subject. 
     
     
         16 . The system of  claim 15 , the processor further configured to provide an alert to a healthcare provider or an emergency responder. 
     
     
         17 . The system of  claim 11 , wherein the processor is configured to provide the notice via the electronic device. 
     
     
         18 . The system of  claim 11 , the processor further configured to:
 determine a sleep stage of the subject based upon the first signal; and   store a record of the first signal and the determined sleep behavior or disorder in a sleep profile of the subject.   
     
     
         19 . The system of  claim 18 , wherein the memory further stores the sleep profile of the subject. 
     
     
         20 . The system of  claim 11 , the processor further configured to provide the notice to a home monitoring hub in communication with a device comprising the processor.
