摘要： A multi-layer transducer operates with only one system channel per element. Passive switching connects the layers differently for transmit than for receive operation, such as connecting two layers in parallel for transmit and in series for receive. Any passive switching may be used, such as current and voltage limiting circuits. Tuning may be passively switched. Different tuning circuits are passively switched as a function of voltage level between transmit and receive operations.

摘要： A resonant pressure transducer, having a deformable diaphragm or membrane exposed to an ambient environment wherein a pressure force to be measured exists, is provided. A transducer according to the present invention comprises a converter for transmitting the pressure force experienced by the diaphragm to a resonator vibrated by an exciter whose resonant frequency is a function of the intensity of the ambient pressure force to be determined. The converter and resonator are mounted in a rigid frame. The converter has flexible bending means able to absorb the bending moments resulting from the deformation of the diaphragm, so as to transmit to the resonator a tension or a compression force free from bending moments that generate stresses at the entrance of the resonator.

摘要： The present disclosure describes a system for detecting very small displacements of an object with respect to a self oscillating piezoelectric crystal by means of acoustic interference at the crystal. Acoustic energy transmitted by the oscillator is reflected by the object, and movement of the latter causes changes in the phase of the reflected energy. Such changes in turn result in variations in the amplitude of the oscillations. An electronic circuit responsive to the last mentioned variations generates output signals indicative of the instantaneous position of the object.
