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 VRTEX TM
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.
