Abstract: 938,751. Echo distance-measuring. BENDIX CORPORATION. April 7, 1961 [April 11, 1960], No. 12622/61. Class 40 (7). In sonic pulse echo distance-measuring apparatus wherein successive voltages are developed as a function of echo time, means responsive to the difference between the magnitudes of such voltages temporarily disables a utilization means when that difference exceeds a predetermined absolute magnitude. The invention is described as applied to an altimeter of the kind described in Specifications 832,681 and 846,068, in order to obviate false readings due to ground reflections of engine noise. The voltage across capacitor 43 is differentiated in unit 50 and a positive-going pulse from unit 51 is fed to a low-pass filter 53; inverter 57 ensures that both falling and rising voltage changes at the capacitor are effective. The filter output, if above an amplitude corresponding to a predetermined first rate of height change, causes Schmitt trigger circuit 54 to switch-over multivibrator 55 (re-set at the beginning of the next emission cycle) and switch 64 opens. If circuit 30 detects no echo signal above its threshold for at least 1.2 seconds, switch 64 is again opened and lamp 32 is energized. Circuit 65 is provided to ensure that the reading of meter 66 changes at a rate not exceeding a second predetermined value which is less than that required to trigger circuit 54, Fig. 3 (not shown), and to provide a signal to cause circuit 73 to increase receiver sensitivity at heights above a predetermined value.
