The Rat Digitizer
The "Rat" (trademarked and patented) is an all purpose portable X-Y digitizer. The Rat will revolutionize the way any paper copy can be digitized.
Application programs now written for the Rat will digitize:
The Rat was originally designed to digitize well logs for the Petroleum industry, but now its uses have greatly expanded into mapping, seismic work and chart analysis. The latest DIGGIS software program gives the Rat capabilities to be useful in architecture, engineering and CAD markets. Anywhere a digitizing table is used the Rat will be able to replace it.
Physical Aspects Of The Rat
The Rat is small and ergonomic. It weighs 2.75lbs (1.25kg) and measures
approximately 7.0 inches (17.8cm) long by 3.0 inches (7.6cm) wide and 1.5
inches (3.8cm) high. Full gripping power is accomplished by two external
side wheels that have diamond banding around the circumference. These
bands bite into the paper that you are digitizing. A rotary encoder on
this axle gives you an "X" value. The "Y" value is obtained by connecting
a sliding cursor with very fine black lines onto the front of the Rat
body. Twin Hewlett Packard barcode readers, 90 degrees out of phase - to
detect direction, decode the very fine lines. Absolute accuracy of the
hardware system is .003 of an inch. You now have an X & Y hardware
system for digitizing.
Advantages Of The Rat
The Rat is an extremely ergonomic digitizing system. You can always be
comfortably sitting down while digitizing with the data right in front of
Price of the Rat digitizing system is well below that of the large
format digitizing tables.
