hardware for the acquisition parameters
INFANT POSTURE
 Detect the position of infant during sleep
 LSM330DLC inertial sensor is used without
gyroscope
 Set threshold value to minimize the small
fluctuations in accelerometer and it allows to
control the tilt angle posture
 Position gets updated when there is a valid
change
 3D-accelarator is to recognize the force of gravity
 ‘A’-Infant is lying on his back
 ‘B,D’-Infant is lying on his side
 ‘C’-Infant is lying on his stomach
POSITION CHANGE
Fig 3:Acceleration variation on each axis over
position change
A B C D
BREATHIN RATE SENSOR
 The same 3D-accelarometer is used here with a
sampling rate of 10Hz.
 Measures 60 breaths per minute
Fig4:Smoothed and unsmoothed data acquired from the 3D-accelarometer
STRATERGY TO MEASURE
BREATHING RATE
 Implementation of the smoothing algorithm
results in huge energy consumption
 State machine with three possible states are used
to minimize the power consumption
 Middle state
 High state
 Low state
RESULT OF BREATHING RATE
SENSOR

back
Fig 5:Axis’s values while infant is lying on his
back
 Infrared thermopile sensor-TMP007
 Measure without any contact with the skin
 Provides digital interface(I2C/SMBus)
 Thermally isolated from PCB
BODY TEMPERATURE
Temperature Sensor
GATEWAY
 Beagle Bone Black, with a Debian Wheezy image is
installed
 Network service was provided by lighted server with
PHP5.1
 Serial port communication protocol was used for
communication
 TL-WN725N is used to connect gateway to router
Fig 7:Gateway :shield placement on the Beagle Bone
Board
H Medical Web Interface
 Helps the user to retrieve the information from
SWS
 Developed in PHP,SQL,Javascript,HTML5,CSS3
 Worked on any device independent of OS
 Helps to
 Generate charts
 Time-lapse animation
 Export data to different type of files
 Allows to add new users
 Monitor multiple infants
Results obtained after evaluation
 Heart rate sensor
