    摘要： A microfabricated acoustic transducer with suppressed substrate modes includes a diaphragm containing an upper electrode suspended above a substrate containing a lower electrode; the substrate may or may not contain electronic circuits. The substrate modes are suppressed by either thinning the substrate such that a longitudinal ringing mode occurs outside of the frequency band of interest or applying a judiciously designed damping material that absorbs acoustic energy from the substrate on the backside of the transducer substrate, or by both thinning the substrate and applying the damping material. The damping material has an acoustic impedance that matches the acoustic impedance of the substrate and is lossy.

    摘要： An ultrasound imaging system may use a capacitive membrane or electrostrictive ultrasound transducer to realize isotropic volumetric imaging with bias-line element selection and a variety of aperture synthesis techniques. Two dimensional beam formation may be performed by using a beamformer to focus along one dimension, and then perform a second round of “off-line” or “retrospective” beam formation along the other direction.

    摘要： A light-weight display easel assembly for use with photographs and photographic greeting cards is described, wherein the display device is a substantially planar sheet or panel of paperboard or similar cellulose-containing material having a plurality of die-cut flaps thereon, each of the die-cut flaps having one scored edge which allows for the outward folding of the flap. The display easel further comprises a plurality of adhesive strips on the front face of the paperboard, for attachment of a photograph or photographic greeting card thereto. The display easel, once assembled, is lightweight enough such that it can be mailed without the need for excess postage fees. Additionally, due to the attachment of the display easel to substantially the entire back face of a photograph, the entire photograph is fully supported and is therefore resistant to creases, indentations, warping, and other damages which can occur during the mailing process.

    摘要： Medical diagnostic ultrasound imaging is performed with a multi-dimensional transducer array and an imaging system for planar scanning. The elements of the array may be distributed on a periodic grid with aperiodic shifts in position. When a one-dimensional array is formed on the array, the aperiodic shifts better distribute acoustic energies, reducing peaks in side lobes. Using a layered structure of switches underneath the acoustic elements, side lobes may be further reduced. The switches are used for interconnecting elements to form macro elements of the one-dimensional aperture on the multi-dimensional array. The switches are distributed on a grid corresponding to the desired imaging frequency. The acoustic elements are distributed with a finer pitch. The finer pitch allows formation of the macro elements for the one-dimensional aperture where the edges of the macro elements have fewer or no periodic patterns.
