DAO Metrology Controller

The DAO Metrology Controller is an integrated stand-alone
controller that can adapt to any existing metrology stage system
currently on the market.  This is a compact self-contain unit
equipped with a 15-inch touch-screen interface (gloves are no
problem).  Therefore, mouse and keyboard devices are not
necessary (mouse device is optional).  

The high-end 30fps video frame grabber embedded inside our
controller is beyond the future of video metrology.  It is capable of
yielding up to 1024x1024 resolution medical grade images and
many other features not found in standard video frame grabbers.  
It is currently used in many projects at NASA and US Air Force.

In addition, our controller does not need external video monitor,
computer monitor, motion controller, and power supply.  All are
integrated into one compact unit to eliminate complicated wiring.  
It only requires standard 120-240VAC from the wall outlet.

There will be a few quick-release cables connecting our controller
to your stage motors, encoders, and travel limits.  Our controller
has all of the necessary connectors in the back to completely
control your existing metrology stage and its peripheral devices.  
Peripheral devices includes up to three light sources, laser auto-
focus, motorized objective lens turret, and stage joystick.

Included with the DAO Metrology Controller is an analog joystick.  
Similar like our DAO Joystick Controller, it is ergonomically
designed for both left-handed and right-handed operators.  This
joystick is an addition to the software joystick available fulltime on
the touch-screen.

Measurements are performed by our state-of-the-art CMM
software, Proximus™ 100.  The application launches
automatically upon power up.  The 32-bit application software
operates at 1024x768 resolution on a 15-inch LCD panel with vivid
24-bit color.  The live video window is a 16-bit color at 640x480
resolution with graphic overlays for visual aid to construct
measurement programs.  The user interface is uniquely designed
for quick writing of sophisticate measurement programs.

Proximus™ 100 is a self-guide and self-taught application.  It is
capable of eliminating virtually all user errors.  Proximus™ 100 is
comparable to, if not surpass, some of the most sophisticate
CMM software currently on the market.  Unlike many metrology
application software that operate on Windows® Desktop which
requires proper shutdown, the DAO Metrology Controller can be
powered down at anytime without concern of file corruption.

Key Features:
