  • Ultrasonic digital receiver
    Patent number: 3943491
    Abstract: A receiver of ultrasonic pulses having a known pulse width and at a known spacing includes a gate which is normally conditioned to accept the ultrasonic pulses. When the first pulse is received, however, the gate is opened thereafter only when subsequent pulses should be present and is closed when no pulses are expected. Such an arrangement prevents multipath signals being interpreted by the receiver as information.
