COMPUTER ASSEMBLY (CPU)
FUNCTIONS, USER CONTROLS,
INDICATORS & VIDEO/AUDIO
COMPONENTS
Once the CPU is powered up it becomes the main information processing component of the VRTEXTM 360. The CPU receives commands from User Interface Controls via the Digital I/O Interface Module and USB connections. The CPU processes these commands and sends acceptance signals back to the User Interface Indicators and to the Digital Interface Module and Display LED PC Board.
The CPU receives real time feedback signals from the Polhemus Interface Module and compares these to the commands and procedure selections set forth from the User Interface Controls. This processed video and audio information is then sent to the Face Mounted Display (FMD) Control Unit, the Video Graphics Display Splitter (VGA) Monitor and the Video and Audio Receptacles.
