Class Information
Number: 340/853.3
Name: Communications: electrical > Wellbore telemetering or control (e.g., subsurface tool guidance, data transfer, etc.) > Selective control of subsurface equipment
Description: Subject matter having a communication link for controlling one or more devices in the underground equipment to obtain a plurality of results by transmission of a designated one of plural distinctive control signals over a smaller number of communication lines or channels than the total number of possible distinct results and which controls the underground equipment in accordance with the signal content.
