Draw a diagram

1. This      is problem 5.13 from your text book. You can use any Free UML tool      (see the list on the Moodle or Visio software tool) You need to draw a UML      diagram for a system.

Consider a hospital’s patient monitoring system. Each patient is connected to machines monitoring blood pressure, heart rate, and EKG. These machines issue a Boolean signal indicating a FAIL or WORKING condition. The results of each of these machined are ‘ORed’ together to form a signal called ALARM. The ALARM signals for each of the rooms (one patient per room) are then ‘ORed’ together and sent to the nurse’s station. If any machine on any patient indicates a failure, the emergency alarm is sounded and the nurse is directed to the appropriate patient and machine. Draw a data flow diagram/ UML diagram for such a system.
