  • Acoustic transponder receiver circuit
    Patent number: 5008859
    Abstract: A transponder that responds differently to two different input signals. The first input signal is at a first frequency. The first input signal is detected by a first powered detector that operates at the first frequency. The transponder responses in a first mode to the first input signal. The second input signal consists of short pulses at the first frequency and at a second frequency. The transponder responds to short pulses at the first frequency by powering a second detector. The first and second detectors then detect the second input signal. The transponder responds in a second mode to the second input signal.
