SYNOPSIS

• There is a need to develop a new low cost
  indigenous electronic cradle because the existing
  cradles are imported and costly. Final year ece
  projects in chennai ,bangalore ,vijayawada,kakinad
  a. This paper presents the design and
  implementation of a new indigenous low cost Baby
  Cradle that swings automatically when baby cries,
  for this it has a mobile phone video analyzing
  system which detects the baby cry video with
  audio and accordingly the cradle swings till the
  baby stops crying. The speed of the cradle can be
  controlled as per the user need. The system has
  inbuilt alarm that indicates two conditions
  first when the mattress is wet, which is an
  important parameter to keep the baby in hygienic
  condition, second when baby does not stop crying
  within a stipulated time, which in turn
  intimated that /www.embeddedinnovationlab.combaby
  needs attention. / .This system helps parents and
  nurses to take care of babies without physical
  attention.

INTRODUCTION

• Since the evolution of humans , mothers play an
  important role in taking care of children. Final
  year embedded system projects in chennai
  ,bangalore,vijayawada,kakinada.
• But parents in the present world are busy in
  their professional life.
• The system is designed to help parents and nurses
  in infants care.
• The project intimates the care takers by sending
  both alert message as well as video and audio
  calls when a baby cries.
• www.embeddedinnovationlab.com
• Parents can control the cradle movement with a
  keypad press.
• Respiratory sensors and Wet sensors are also used
  to detect respiratory rates and wetness
  respectively.
• Thus this project is a solution, for parents at
  home who lose sleep over a baby who constantly
  wakes up and cries.

6
Working

• When the baby in the cradle cries, the cry will
  be detected by the microphone.
• The signals are then amplified by the amplifier
  then it is sent to the peak detector where cry
  peaks will be detected and further the signal is
  sent to microcontroller. Final year mechanical
  engineering projects in chennai,bangalore,vijayawa
  da,kakinada
• Sensors used
• Wet sensor.
• Temperature sensor.
• Respiration sensor.
• The GSM modem via RS232 interface, the modem
  will send a message or a call to the mobile
  number stored in the modem as an alert.
• www.embeddedinnovationlab.com
• Using the Skype technology can observe the video
  of the baby.
• Control the Cradle movement.

Design Aims

• When baby cry parent can automatically swings
  the cradle till the baby stops crying.
• Final year mechanical projects in
  chennai,bangalore,vijayawada,kakinada
• Alerts the parent when the mattress gets wet.
• Alert parent by giving temperature as well as
  respiration rate by of SMS.
• Alerts the parent by giving call or sending
  SMS.
• The parents can have a video interface and watch
  their baby LIVE via 3G! SKYPE TECHNOLOGY.

LITERATURESURVEY

• Steven Bang
• Steven Bang designed automatic baby rocker having
  a noise sensor to detect baby cry. Noise sensor
  consists of Electret MIC with a pre amplifier
  (2n3904 transistor). Signal from noise sensor is
  fed to microcontroller which is used to control
  the DC motor. Final year engineering projects in
  bangalore,chennai,vijayawada,kakinada. Few
  colorful lights made up of LED are used to
  entertain the baby while being rocked.

LITERATURESURVEY

• Yang Hu
• Yang Hu proposed an algorithm for adjusting the
  bassinet swaying extent by the sensor signals.
  The bassinet is made up of an adaptive swaying
  device and other sensors network. While baby is
  crying, the sensors network can judge the reason
  according to detecting parameters, giving the
  different signals to control circuit. At the same
  time, the bassinet starts to sway slightly. The
  swaying rhythm can be adjusted according to
  parameters from baby status. 2.

LITERATURESURVEY

• Marie R.Harper
• Marie R. Harper invented a crib adapted to be
  rocked automatically. Once the crib is manually
  tilted in one direction and released, this
  permits the inertia to actuate the locking and
  actuating arms to operate under the biasing force
  of spring in conjunction with the gear. Thus
  spring loaded motor begin to operate and the
  lever arm is oscillated in back and forth
  movement. This provides the same effect as would
  be achieved by the mother rocking the crib
  containing the baby. Oscillation of crib is
  stopped when the slightest resistance is incurred
  3.

LITERATURESURVEY

• Gim Wong
• Gim Wong presented an Electronic device that can
  be attached to conventional pivotally mounted
  type crib. Which is actuated by baby cry voice
  picked up by the microphone giving short throw
  type rocking action to crib. Very similar to a
  person rocking the crib by pushing and pulling on
  the foot or headboard . There is a sensitivity
  control so that baby voice only actuate the
  rocking action and a timer to controller the
  duration of rocking action 4.

LITERATURESURVEY

• Chua-Kai-Hsieh
• Chua-Kai-Hsieh proposed a baby cry recognizer
  which includes an amplifier circuit for
  amplifying a received sound signal. In response
  to the amplified sound signal, a pulse generator
  circuit generates a pulse signal having zero
  crossings which are aligned with zero crossings
  of the amplified sound signal. The pulse signal,
  in turn, is inputted to a signal recognition
  circuit. The signal recognition circuit outputs a
  signal indicating that a babys cry was detected

LITERATURESURVEY

• Anritha Ebenezer
• Anritha Ebenezer gives an approach to design a
  baby cradle consisting of cry analyzing system
  which detects baby cry. According to sound
  intensity cradle swings. It has six rocks per
  minute. It has wet sensor to indicates baby wets,
  www.embeddedinnovationlab.comwhenever baby wets
  resistance would change thus sending a signal.
  Other sensors include temperature sensor to
  display baby temperature, respiratory sensor that
  sends a signal in apnea condition. GSM modem via
  RS232 is used to send message to parents in case
  baby does not stop crying with in a particular
  instant of time 6.
