A method of generating intender leads in a distributed computer system includes the steps of identifying purchase indicators and extracting prospect identifiers from the purchase indicators. The detection circuit for an electronic device receives power information from an external power supply via a cable to generate the control signal that controls DC input voltage output from the external power supply. The output of the power supply is modulated by a follower potentiometer coupled to a lever arm which resiliently bear against a segment of wire unwound from the supply spool in order to monitor its pulling tension. The auger is mounted such that both rotational axial movements are enabled during operation.
