Abstract
A fall monitor was previously created for use with children under treatment for cerebral palsy at Shriners Hospitals for Children, Northern California. The two functions of the fall monitor are to record the activity of a child and to detect when the child falls down. The existing fall monitor records a child's activity and falls, but it does not record the place where the activity and falls occurred. A project is undertaken to study the feasibility of adding a Global Positioning System (GPS) receiver and a Secure Digital (SD) card to the fall monitor to solve the problem of recording the location of activities and falls. The GPS receiver is connected to the same microcontroller as in the fall monitor. The microcontroller extracts the position of a child from the receiver data and saves the information in the SD card. Later, it uploads that information to a personal computer (PC). The resulting device will be able to give position in terms of longitude and latitude at which the child's activity and falls took place.
