  • Patent number: 10368832
    Abstract: Issuance of ultrasound pulses to a volume and receiving echo data is followed by estimating, based on the received data, center frequency subvolume-by-subvolume. Distinguishing between heart and lung tissue occurs based on a result of the estimating, and may include automatically identifying a spatial boundary (332) between the heart and lung tissue (324, 328), or a user display of center frequencies that allows for visual distinguishing. The issuance can include issuing, ray line by ray line, pair-wise identical, and/or pair-wise mutually inverted, ultrasound pulses. Center frequency calculations may be made for incremental sampling locations of respective imaging depth along each of the A-lines generated from echo data of the rays. The distinguishing might entail averaging center frequencies for locations along an A-line, and applying a central frequency threshold to the average. The leftmost of the qualifying A-lines, i.e.

  • Publication number: 20130125656
    Abstract: A method and apparatus for attenuating a shockwave propagating through a first medium. The method may include the steps of detecting a shockwave-producing event, determining a direction and distance of the shockwave relative to a defended target, and interposing a second medium between the shockwave and a defended object. The second medium is different from the first medium and the shockwave is attenuated in energy as it passes through the second medium prior to reaching the defended object.

  • Patent number: 8316712
    Abstract: Inspecting for fracture hazards by detecting a presence of at least one flaw development process in an equipment under inspection, the flaw development process being corrosion product nucleation and development, pitting, plastic deformation development, and/or micro-cracking. Detecting the presence of the flaw development process includes (a) determining at least one characteristic acoustic emission (AE) signature associated with a respective flaw development process, and (b) measuring an AE from each of a plurality of locations within the equipment. Presence of the respective flaw development process is identified only when the measured AE conforms to the characteristic AE signature within a predetermined tolerance. A fracture hazard is determined to exist only when (a) a quantity of the identified flaw development processes exceeds a first predetermined threshold and/or (b) a magnitude of at least one of the identified flaw development processes exceeds a second predetermined threshold.

    Abstract: Methods and apparatuses for performing assays involving binding material elements with a plurality of bonds over a substantial area of a surface of a resonant device establishing a normalized exposure. The methods and apparatuses also involve controlling an external influence applied to the material elements over a first period of time and measuring a signal during a second period of time that is indicative of the change in the amount of material elements bound to the surface relative to the normalized exposure. In some cases, the measured signals are integrated with respect to time to determine the time averaged amount of material elements bound to the surface.

  • Patent number: 8220333
    Abstract: A measurement device and method for diagnosing noise in fluidic systems. A microphone, which is arranged at least partially in the area of the flow medium, compensates for pressure surges in the flow medium. The microphone receives the noise via a membrane and converts it to an electrical signal for evaluation of the noise source by an electronic diagnosis unit. To compensate for pressure surges in the flow medium, the membrane of the microphone is arranged in a housing, which is open on both sides of the membrane and whose two openings have pressure applied to them by the flow medium as a sound source, with at least one of the two openings being provided, in order to detect noise, with filter means for attenuation and/or time delay of frequencies which are in an expected noise spectrum, while the filter means allows lower frequencies produced by the pressure fluctuations in the flow medium to pass through.

    Abstract: The present invention provides embodiments relating to novel methods for determining, monitoring or detecting particle size distribution of a medium. In a preferred embodiment, the method comprises comparing a measured ultrasound attenuation spectrum of the medium with a calculated attenuation spectrum, where the calculated attenuation spectrum is obtained by accounting for the scattering of ultrasound waves into the receiver. The methods of the present invention can be used to determine particle size distribution in a dense suspension of particles in the intermediate wavelength regime. In other aspects, methods of the present invention may also be used to monitor changes in particle size distribution, infer the shape of particles, provide feedback to a process involving a change in particle size, and determine the completion of a dissolution process.
