Title: Amplifier for AC signals with superimposed DC voltage - has second switch to set DC average level of output as wanted
Inventor: AEPPLI KURT
IPC: G01B7/12
Filed: 1976-12-30
Abstract: The amplifier, for AC signals with a superimposed DC voltage, allows any DC voltage to be selected as average for the AC output. A DC current source (10) can be connected by a further switch (S11) to the feedback. When this switch is open the amplifier behaves as in 2143414. With this switch and the first switch closed however, current flows through the resistors (R2, R5) and the capacitor (3) charges. The output voltage (UA) moves so that the current through (R2) is zero. The voltage at (A) is therefore zero but current still flows through (R5) to maintain the output.

Patent DE-2709571-A1 (DE)
Inventor: VILKOMERSON DAVID HERMAN RAPHA
IPC: G01B9/02
Filed: 1977-03-04
Abstract: An interferometer, that simultaneously employs two phase-quadrature reference beams of coherent light which interfere with a signal beam of coherent light reflected from a spot of a displaceable signal mirror insonified by an ultrasonic wave, permits an output signal to be derived which is proportional to the sum of the squares of the ultrasonic frequency component of the interference between the signal beam and each respective one of the reference beams. This output signal is inherently substantially proportional to the intensity of the ultrasonic wave then insonifying the spot of the signal mirror and independent of random phase drift and environmental vibrations in the interferometer. The interferometric technique of the present invention, which permits the ultrasonic wave to be in the form of pulse bursts of only a few cycles so that the output signal can be range-gated, is suitable for use in an ultrasonic-wave measurement and image display system.
