Abstract
Integrated circuits contained in a rail are passed through cylindrical electrodes. Two electrodes are connected to an oscillator to transmit out of phase fields. A receiving electrode's output has the residual oscillator frequency component removed by a nulling network and summation device, whose output is fed to a band pass amplifier and balanced demodulator, which receives a phase shifted input from the oscillator. Demodulator output components at and above the oscillator frequency are removed by a low pass filter. A demodulator output above the reference voltage triggers a counter.
