The
California based company Stokes Publishing Company, Inc. distributes under the label
"The Educator®" calculators optimized for teaching purposes. William T. Stokes filed already July 30, 1991 the US Patent Application
U.S. Pat. No. 5,035,502 with the title
"Transparent calculator for overhead projection".
Both the
keyboard and the display are made from translucent glass and plastics. Using a
simple overhead projector the teacher could demonstrate easily the function of a
calculator.
The successor of the original Advanced emulates the Texas Instruments
TI-34 introduced already in 1989 and redesigned in 1996.
Overhead™ Calculator is a trademark
