A system for identifying and responding to infant breath detection, the system comprising: a sensing device for collecting infant motion data; a breath detection module , the breath detection module comprising: a filter module to filter non-breathing related motion data from the collected infant motion data; a frequency conversion module to convert the filtered breathing related motion data to a frequency domain associated with infant breathing; a data analysis module to determine an infant breathing pattern within a frequency domain data corresponding to the infant's breathing rhythm, wherein the breath detection module is configured to monitor for breathing abnormalities by comparing the breathing pattern to an infant breathing profile while concurrently analyzing the collected infant motion data for variable breathing patterns specific to the infant and modifying the infant breathing profile to account for natural variations in breathing over time; and a data process module ; and a communication facility configured to communicate between the sensing device and the breath detection module ; wherein, when the infant breathing profile is interrupted, the data process module determines if the infant breathing has stopped; wherein if breathing has been determined to have stopped, the data process module determines if the stoppage is normal or abnormal; and wherein if the stoppage is abnormal, the breath detection module generates an output signal. a sensing device for collecting infant motion data; a breath detection module , the breath detection module comprising: a filter module to filter non-breathing related motion data from the collected infant motion data; a frequency conversion module to convert the filtered breathing related motion data to a frequency domain associated with infant breathing; a data analysis module to determine an infant breathing pattern within a frequency domain data corresponding to the infant's breathing rhythm, wherein the breath detection module is configured to monitor for breathing abnormalities by comparing the breathing pattern to an infant breathing profile while concurrently analyzing the collected infant motion data for variable breathing patterns specific to the infant and modifying the infant breathing profile to account for natural variations in breathing over time; and a data process module ; and a filter module to filter non-breathing related motion data from the collected infant motion data; a frequency conversion module to convert the filtered breathing related motion data to a frequency domain associated with infant breathing; a data analysis module to determine an infant breathing pattern within a frequency domain data corresponding to the infant's breathing rhythm, wherein the breath detection module is configured to monitor for breathing abnormalities by comparing the breathing pattern to an infant breathing profile while concurrently analyzing the collected infant motion data for variable breathing patterns specific to the infant and modifying the infant breathing profile to account for natural variations in breathing over time; and a data process module ; and a communication facility configured to communicate between the sensing device and the breath detection module ; wherein, when the infant breathing profile is interrupted, the data process module determines if the infant breathing has stopped; wherein if breathing has been determined to have stopped, the data process module determines if the stoppage is normal or abnormal; and wherein if the stoppage is abnormal, the breath detection module generates an output signal. <EOS>
