    摘要: An aspiration apparatus adapted to allow aspiration verification of a liquid such as of a biological liquid or reagent liquid, especially at low aspiration volumes (e.g., less than 25 μL). The apparatus includes a pump operable at an operating frequency, the pump optionally including a pumping chamber, a probe having a probe interior, a main supply line containing a backing liquid coupled to and extending from the pump and including the probe interior, a striction coupled to the main supply line, or the pump chamber, if present, and a reservoir fluidly coupled to the striction, wherein the striction is sized to minimize backing liquid flow through the striction at one or more disturbance frequencies above the operating frequency. Systems and methods for carrying out the liquid aspiration are provided, as are other aspects.

    摘要: A sensor system for sensing a process variable of fluid at a first location including a variable resonator disposed at the first location having a resonant frequency which varies in response to the process variable of the fluid and responsively provides a resonant acoustic signal at the resonant frequency indicative of the process variable. An acoustic sensor disposed at a second location which is spaced apart from the variable resonator is configured to receive the resonant acoustic signal transmitted from the variable resonator. Measurement circuitry coupled to the acoustic sensor configured to provide a process variable output related to the process variable of the fluid in response to the received resonant acoustic signal.

    摘要: Zum Zweck der Manometrie werden in eine Flüssigkeit, in welcher ein wolkenartiges Gebilde von stabilisierten Mikrobläschen erzeugt wurde, Ultraschallimpulse eingestrahlt und zu einer Wechselwirkung mit den Mikrobläschen gebracht. Die Amplituden- und/oder Frequenzänderungen der Ultra­schallstreusignale werden gegenüber den eingestrahlten und/oder vorher empfangenen Ultraschallimpulsen re­gistriert und ausgewertet. Mittel zur Blutdruckmessung, die bei dem Manometrieverfahren verwendet werden können, werden beschrieben.

    摘要: A pressure sensor includes a case, a vibrator, a detector, and a processor. The case includes a tubular section and a flat section. The tubular section has a hollow having an opening and is configured to be filled with a target fluid. The flat section closes the hollow. The flat section has a first surface facing the hollow, and a second surface opposite to the first surface. The vibrator is disposed on the second surface of the flat section of the case. The detector outputs a signal according to a vibration of the vibrator. The processor is operable to detect a frequency of the vibration of the vibrator based on the signal output from the detector, and to detect a pressure of the target fluid based on the detected frequency of the vibrator. This pressure sensor has a high sensitivity and excellent characteristics.
