  • Patent number: 7654960
    Abstract: A method and a device (1) for ultrasound measurement of the blood flow through a heart valve are proposed. To permit a simple, automated measurement, it is proposed that the measurement area (9) of a measurement beam (7) is moved three-dimensionally by means of a multi-array transducer (11) and continuously evaluated for characteristic Doppler signals. It is further proposed to evaluate several measurement beams (7) with offset spatial, partially overlapping measurement areas (9) and/or several reference beams (8) with offset spatial measurement areas (10) for determination of the opening surface area, the volumetric flow rate, the flow volume and/or a value proportional thereto.

  • Publication number: 20090205435
    Abstract: A circuit module, in particular a tire sensor module, which at least includes: a substrate, on or in which at least one component is mounted, a piezoelement, which has at least one clamping region and at least one oscillatory region, the piezoelement being clamped in its clamping region on the substrate or on an arrangement secured to the substrate, and its oscillatory region being accommodated in a manner that permits oscillation, contacts provided on the piezoelement for tapping off a piezoelectric voltage, and a current-supply circuit, which receives the piezoelectric voltage generated by the piezoelement, being used as a voltage source for supplying power to the circuit module. The piezoelement is preferably clamped between at least two substrate elements, at least one cavity being formed within which the at least one oscillatory region of the piezoelement is accommodated in a manner that permits deflection, and is limited in its oscillation displacement.

  • Patent number: 7535325
    Abstract: A component is provided for an impedance change in a coplanar waveguide which includes two grounding conductors and a signal line lying between the grounding conductors, as well as a conducting connecting element, which has a covering surface for the two grounding conductors and the signal line, and is electrically insulated, so that in each case a capacitor is formed. The connecting element and the lines are situated and arranged so that the respective capacitor between the grounding conductors and the connecting element has an invariable capacitance, but the capacitor between the connecting element and the signal line has a variable capacitance. A structure is also provided in which in an exactly opposite way, the respective capacitor between the grounding conductors and the connecting element has a variable capacitance, but the capacitor between the connecting element and the signal line has an invariable capacitance. Furthermore, a method for producing such a component is also provided.

  • Publication number: 20030109785
    Abstract: Techniques are provided for obtaining selected instantaneous area measurements for a dynamic orifice through which blood is flowing in at least one direction, for obtaining instantaneous flow rates of blood passing through such a dynamic orifice and for obtaining flow volume for blood passing through a dynamic orifice. All of these techniques involve ensonifying a thin sample volume of blood flow exiting at the orifice, which volume is in a region of flow which is substantially laminar, such region normally being the vena contracta for the orifice, with an ultrasonic pulsed Doppler signal, receiving backscattered signal from blood within the sample volume and forming a power-velocity spectrum from the received backscattered signal. Techniques are disclosed for assuring that only laminar flow is looked at in forming the power-velocity spectrum.
