  • Patent number: 10465507
    Abstract: Methods, systems, and techniques for controlling voltage applied across a piezoelectric stack of a downhole acoustic transmitter. At least one of the temperature of the stack and the compressive stress applied to the stack is monitored.

  • Patent number: 10315223
    Abstract: The present invention provides a transverse width mode for sound and ultrasound generation and reception. The transverse width mode can be combined with conventional longitudinal or transverse mode to make sonic and ultrasonic transducers and/or arrays of multiple resonant modes, a broadband coupled mode or their combinations. Due to its half-wavelength resonance nature, when the transverse width mode is designed to operate with suitable head mass and/or matching layers, ultra broadband transducers of moderate to high sound pressure level can be realized. With active materials having low transverse sound velocities, the transverse dimensions of each transducer element can be kept about or smaller than half the wavelengths of sounds in water and human tissues, making the transverse width mode highly suited for various array designs and operations.

    Abstract: In a method of evaluating porosities, firstly, an ultrasonic wave is input in a thickness direction of a composite material to an incident surface which is one of the surfaces of the composite material having a multi-layer structure, and a reflective wave (whole reflective wave) is received from the incident surface. Then, the time-frequency analysis for the received whole reflective wave is performed. Thus, the temporal change information of the reflective wave (interlayer reflective wave) included in the whole reflective wave and reflected on an interlayer interface of the multi-layer structure, is obtained. This change information is suitably used to evaluate a distribution of porosities in the thickness direction of the composite material.

  • Patent number: 10028724
    Abstract: An ultrasonic diagnosis apparatus according to an embodiment includes a controller, a processor, and an image generator. The controller selects at least one transducer element in a reception aperture formed of a transducer element group arranged in a predetermined direction, based on at least a deflection angle of an ultrasonic wave transmitted to a subject. The processor performs processing on at least one reception signal of a plurality of reception signals generated in the reception aperture such that a signal intensity of a reception signal generated in the at least one transducer element selected by the controller is reduced to be lower than a signal intensity of reception signals generated in transducer elements other than the at least one transducer element, to output the reception signal of the reception aperture. The image generator generates ultrasonic image data, based on the reception signal of the reception aperture.
