1. Infant Monitoring Device (IMD) Jack Followay, Jr. David Schmidt Bret Hodge Kerey Tassin Thomas Supercinski

2. IMD Description zCreate a device to replace existing infant monitors with a monitor that will allow the parents to view their child’s vital signs, such as temperature, heart rate, blood pressure, and breathing. zThe IMD will sound an alarm to immediately warn the parents if breathing stops or heart rate becomes abnormally low. zIt will also aid the pediatrician when it is time for the infant’s checkup by allowing him/her to view these vital statistics in advance and possibly detect early warning signs.

3. Project Overview

4. Key Components zVxWorks zIMD Application zSerial Port Communications zIMD I/O zHospital Application zSensor Simulation

5. VxWorks zDesign yRTOS that supports most POSIX standards ySupports multi-threaded IMD app ySupports network communication zIssues y“High-level” documentation yLack of BSP, ROM monitor
