Title: Apparatus to measure viscoelasticity of cells
Inventor: BAUSCH ANDREAS
IPC: G01N11/10
Filed: 1997-10-16
Abstract: The apparatus to measure the elastic and  viscous characteristics of materials has the shoe (2) of the magnet (1) in a shape so that the magnetic force directed at the probe (7) is identical with a plane of the sample and parallel to the plane. When using identical magnetic probes, in lines, they are equidistant from the pole shoe and have the same value, where the vector of the magnetic force can lie on a focal plane for observation of the probes through a microscope. The magnetic probes are spherical particles with a diameter of  <=  5  mu m. The pole shoe is shaped to give a sharp edge. The deflection of the magnetic probes is determined and set with digital image processing. The force is calibrated, to act on the probes.  The magnet and the sample holder allow examination by a light microscope, to detect the deflection of the magnetic probes of a unified diameter in a mono-dispersion. The gap between the magnetic pole shoe and the magnetic probes can be adjusted (3), to bring the pole shoe edge into the proximity of a magnetic probe to be measured. The cells are held on a substrate, for a shear force to be exerted by the magnetic field. The cells are held in place such as by micro-pipettes, so that the magnetic force can act in the required direction in relation to the cell, and the probes are positioned in relation to the cell. The apparatus is combined with fluorescent microscopic working. Nonmagnetic probes are used with the magnetic probes, which have a specific cell bonding action or are bonded to the cells by immunological methods. The pole shoe is cladded with a thin and flexible material to prevent soiling the samples. The shift in the magnetic particles is detected by induction currents. The sample holder (4) has a flexible or rigid material at the sides (5), so that the pole shoe can be brought into microscopic proximity at the probes without contact with the sample volume, so that the sample cannot be contaminated by the pole shoe. The sample holder, as used for cell culture, can be wholly sterilized. The magnetic probes are bonded to the plasma membrane by specific antibodies, by chemical or physisorption.  The magnetic probes are inserted into the cytosome by phagocytosis, micro injection, electroporation, scrap loading, lipid fusion or specific coating of the balls such as by adenovirus cladding. The magnetic probes have either a specific or nonspecific bonding in the cytosome of the cells. The nonmagnetic particles are in mechanical contact with the cells, for their lateral deflection following the deflection of the magnetic probes to give the pathological condition of the cells, which can be visualized.

Abstract: The invention relates to method and device (1) for regulating at least one delivery quantity of a compressor unit (2) driven by an electric drive motor, such as the volume flow, the pressure and/or the temperature of a medium delivered by said compressor unit (2). At least one measured value is established for the delivery quantity and compared with a specified or limiting value, and, when a deviation occurs, the rotational speed of the drive shaft of the compressor is altered. The measured value of the delivery quantities is indirectly determined by establishing actual values of at least two alternative quantities, such as for example, the motor input power and the rotational speed pertaining to the rotating field of the drive motor. In addition, motor-specific and compressor-specific characteristic quantities are determined from the alternative quantities. Said characteristic quantities are stored in a data storage (5) and have a plurality of value combinations respectively comprised of a value for the delivery quantity and of a value for each of the alternative quantities of the measured value of the delivery quantities. The motor-specific and compressor-specific characteristic quantities can be filed as a characteristic diagram in the data storage.
