3.3 DSM cart
The images acquired by the DSM head are delivered to the system com-
puter (EPU) in the cart. This is a special-purpose computer, optimized to
process the images for storage, manipulation, and stereoscopic display.
The signals generated for display employ the Digital Video Interface (DVI),
delivering high resolution and high refresh rate stereoscopic display
images to the display devices. The DVI signals can be delivered to display
devices with DVI or HDMI cable connections.
The system computer is also fitted with a 2 TB storage drive or larger that
stores at least 100 hours of 3D HD videos. The videos can be immediately
accessed for playback due to real-time compression of the video stream as
it is recorded. The compressed video files can easily be transferred to exter-
nal storage for backup and archival and to free space on the internal stor-
age drive.
The cart also holds a second computer controlling the robotic arm.
3.3.1 Emergency stop
The robotic arm emergency stop is located at the top of the cart. The
robotic arm movement is always under the control of the operator.
►
If there is a malfunction and the robotic arm moves in an unintended
way, first attempt to press the Protective Stop
button on the touch-
screen.
►
If the touchscreen does not respond, use the emergency stop to remove
power from the arm and cease all movement.
Note
When the emergency stop is pressed, the DSM head may move up to 3 cm
(depending on position) due to mechanical brakes locking into place.
