    Patent number: 4622635
    Abstract: A portable terminal for plugging into a well production control system for displaying data from the control system and for entering data into the control system.

A temperature compensating circuit adjusts the brightness contrast on the display module so the terminal can be used outdoors over a wide range of temperatures.
