Monitoring system that alerts caregivers based on position of infant in cradle
Exisiting infant monitoring systems are used to monitor the infant using a microphone placed near to the infaant. But there is no such monitoring system to check the infant's posture and position in the cradle. This patent describes an infant monitoring system for monitoring the cradle to monitor the posture of an infant using an alert mechanism.

1 Introduction and claims
2 Ilustrates the infant monitoring system in a cradle
External rocking system 107 uses a rocking mechanism to rock the stable surface if the processing block determines that the infant is crying. A remote device 106 can receive alerts and data records from various sensors that can be accessed using an application.
