  • Patent number: 5287733
    Abstract: A system collects fluid waste within a closed waste vessel where a waste disposal cycle is determined based upon the pressure level within the waste vessel. In the preferred embodiment, a closed liquid waste vessel accepts waste solutions through conduits having valves controlling conduit fluid communication with treatment vessels. A pressure sensor determines the level of pressure within the waste vessel. A pressurizing device reduces the level of pressure within the vessel. When the pressure within the vessel is lowered to a predetermined level, the valve is opened. When the pressure sensed within the liquid waste vessel then rises above an appointed value, the valve is closed, completing the waste collection of a treated sample. This corresponds to the point in time when the treatment vessel is empty, allowing a sudden rush of air into the waste vessel, raising the vessel pressure to ambient and closing the valve.

  • Patent number: 5287753
    Abstract: A technique for continuously determining and displaying the peak and mean velocities of spectral Doppler information is disclosed. Received spectral Doppler data is examined over a predetermined period to determine the signal to noise ratio of the Doppler signals. Individual instantaneous measurements, or lines, of Doppler spectral information are analyzed in the power versus frequency domain to compare the line information against a noise threshold determined by the signal to noise ratio. The maximum frequency signal component is thereby identified as the peak velocity of the spectral line. Mean velocity is calculated as an intensity weighted mean about the maximum power frequency of the line data. The identified peak and mean velocities are displayed in contrasting colors or shades on a continuously updated and displayed flow velocity versus time spectral display.

  • Patent number: 5287757
    Abstract: A strain-gauge transducer comprises a strain gauge enclosed between pressure members which deform the strain gauge, the strain gauge comprising a plate-shaped substrate provided with strain-detection elements. At least one spring having a flexibility larger than that of the substrate is arranged between the strain gauge and at least one of the pressure members, said substrate and said spring being in contact with one another so as to be jointly subjected to deformations. The spring may be a blade spring, a helical spring, or a cylindrical buffer spring. The excursions of the pressure members can be limited by means of stops. In the case of a blade spring the contact between the substrate and the spring can be controlled by giving the substrate a toothed shape or by providing it with contact elements.
