This invention addresses how an end user can create an electroluminescent device using basic components obtained by the end user as retail items. A second calibration unit is then electrically coupled between the plurality of drivers and comparators, and an AC timing calibration procedure is executed to determine a timing delay for each of a second set of relationships. The receiver’s antenna is directed towards one of a plurality of reception paths and receives a data stream from the transmitter via the reception path that the receiver antenna is directed towards. The positional changes are sensed, and corresponding signals are generated.
