Claim:
1. A wireless signaling system comprising: a stationary element device comprising a stationary element controller, the stationary element device configured to transmit a wireless signal comprising a pair of pulses; and a non-stationary element device comprising a non-stationary element controller, the non-stationary element device configured to: wherein the non-stationary element controller is further configured to compare the transition in the voltage of said each of the pulses to a transition threshold, and if the transition in the voltage of said each of the pulses is more than the transition threshold, then to compare the time interval between said each of the pulses with a directory of signals indicated by a value of the time interval, wherein if the transition in the voltage of said each of the pulses is measured to be greater than the transition threshold and the time interval between said each of the pulses matches a first reference interval, then the wireless signal is interpreted to indicate a calibration mode for the non-stationary element device, and wherein if the transition in the voltage of said each of the pulses is measured to be greater than the transition threshold and the time interval between said each of the pulses matches a second reference interval, then the wireless signal is interpreted to indicate a data collecting mode.
