12
Software User Interface

• Main doctor window

13
Software User Interface

• Search window

14
Software User Interface

• Main patient window

15
Software User Interface

• User information window

16
Software User Interface

• Option and Filter Setting windows

17
Multi-User Design

• Each user is identified by an unique ID
• Each patient is associated to a machine by
  machine ID
• Data sent and store to the database according to
  user and machine ID pair
• User switching by changing user and machine ID
  association
