The invention relates to an operating device comprising a rod which is able to move translationally along an axis with respect to a housing, about an equilibrium position. Each delay cell has a first input port, a second input port, a first output port, and a second output port. The position offsets between the device and contactor are determined by a device-view camera during runtime and a contactor-view camera during calibration time. The registration portion can associate the second communication device with the first communication device based on the registration communication. The content provider records how many of the television-based systems receive the advertising content, and records how many of the television-based systems that receive the advertising content then display the targeted advertisement for viewing.
