The resolution of the DATATAB is .001 inch. It has 
repeatability of .001 inch also, and, because it has a high 
signal-to-noise ratio, readings will not vary more than .001 
inch when the cursor is stationary. This degree of 
stability is unique. Through a proprietary process, ALTEK 
manufactures the DATATAB with an inherent accuracy of +/- 
.003 inch. There is no need to correct for manufacturing 
defects with control electronics or individual firmware. As 
a result, controllers and cursors are interchangeable 
between tables. Of course, less accurate models are 
available for less demanding applications at lower costs. 
ALTEK manufactures a variety of DATATAB tables to accomodate 
the many applications in existence today. In addition to an 
opaque surface, there are surfaces with continuously 
variable intensity backlighting. There are also translucent 
models for customer supplied backlighting. A rear projected 
model is made with an extremely fine wire grid bonded to 
glass - for projecting images from behind and onto the 
tablet's surface. The DATATAB's available sizes range from

Intelligent Digitizing 
The word "intelligent" can be defined as "displaying sound 
judgement" and in today's technical world, "capable of 
performing certain computer functions"  (Webster's II, New 
Riverside University Dictionary). These definitions are 
perfect for ALTEK's use of the word. We consider our 
customers to be intelligent because they are using sound 
judgement when they purchase a digitizer from us. We 
consider our products intelligent because they are quite 
capable of performing certain computer functions. 
In today's world, the customer is considered intelligent if 
he can automate his daily tasks to any degree. The rapid 
increase in automation has been aided by the development of 
the personal computer and its associated peripheral 
devices. A whole new industry has arisen from the fact that 
for a relatively small investment, virtually anyone can 
computerize virtually any application. 
Digitizing products have, in the past, done nothing more 
than generate X,Y coordinates for input into computer 
programs. This meant that there was not much of a choice 
that had to be made when considering brands. The user 
typically would set an accuracy requirement and then search 
for the best buy among vendors who could meet that 
requirement. Once the user received the digitizer, the 
computer software was then used to do any computations 
necessary from the raw X,Y coordinates. The industry,
