    • By a method for measuring in real time properties and/or processes of one or more cells interacting with at least one surface of at least one piezoelectric crystal sensor (1), where one side of the crystal sensor forms a sensor surface, which is exposed to a liquid, containing the cells, the damping of the crystal sensor is measured during and/or after one or more cells are brought into contact with the sensor surface. An apparatus for such a measurement includes at least one piezoelectric crystal sensor (1) with crystal and drive circuit to put the crystal in oscillation and a device to expose one side of the crystal to a liquid, containing the cells. A measuring unit is arranged to measure the damping of the crystal and/or changes in the damping during the interaction of the cells with the crystal surface.

    • A system for measuring particulate concentrations includes a mass sensing device (10). Mass sensing device (10) has a sensing chamber (16) with an intake port (12) and an output port (30). Sensing chamber (16) is divided into an upper portion (14) and a lower portion (18) by a filter membrane (20) which is a planar, peripherally supported filter for entrapping the particulates. The system further features harmonic excitation driver (24) for oscillating the filter perpendicular to its planar surface and a sensor (27) for measuring the frequency of oscillation.

    • Several embodiments include a method of computing a phase composition ratio of a two-phase mixture in a pipe. For example, the phase composition ratio is a void fraction or a dryness fraction. The two-phase mixture can have one or more material substances that do not travel as a whole (e.g., at least two of solid phase, liquid phase, and gaseous phase or two liquid materials of different densities that do not mix). A load cell can measure, continuously, weight of the pipe and content of the pipe. Then, a computing system or a circuit can compute, continuously, a moving average of the continuously measured weight. The computing system or the circuit can compute a change in the phase composition ratio of the two-phase mixture based on the computed moving average.
    • 几个实施例包括计算管道中两相混合物的相组成比的方法。 例如,相组成比是空隙率或干度分数。 两相混合物可以具有一个或多个不作为整体行进的材料物质(例如,不混合的不同密度的固相,液相和气相或两种液体材料中的至少两种)。 测力传感器可以连续测量管道的重量和管道的含量。 然后,计算系统或电路可连续计算连续测量重量的移动平均值。 计算系统或电路可以基于计算的移动平均值来计算两相混合物的相组成比的变化。
