Abstract
A method and system for determining the weight of an infant when the infant is either placed upon a support platform or removed from the support platform, where the support platform may be configured as a bed. A sensor is positioned beneath the support platform that provides a weight measurement to a control unit. The control unit determines a baseline weight for the bed and any object placed on the bed. The control unit calculate a recent weight estimate and determines whether the recent weight estimate is different from the baseline weight by more than a weight threshold. If the difference is greater than the weight threshold, the system generates a weight estimate to a user. Once the weight estimate has been generated, the system adjusts the weight threshold such that the adjusted weight threshold is used in additional processing and calculations of the infant weight.
