Abstract: This invention provides new methods and apparatus for rapidly analyzing single bioparticles to assess their material condition and health status. The methods are enabled by a resonant cavity to measure optical properties related to the bioparticle size and refractive index. Refractive index measurements are useful for determining material properties and biomolecular composition of the bioparticle. These properties and composition are dependent on the health state of the bioparticle. Thus, measured optical properties can be used to differentiate normal (healthy) and abnormal (diseased) states of bioparticles derived from cells or tissues. The methods are illustrated with data obtained from a resonator with a gain medium.

Abstract: A method for checking the plausibility of a torque of an electric machine, calculated on the basis of a machine model, in which a first value of an electromagnetic power of the electric machine is determined from the calculated torque and a rotational speed of the electric machine. Stator current components and stator phase voltage components are calculated from the stator currents and the stator phase voltages with respect to a reference system, which is fixed in relation to the stator.

If a deviation of the first value of the electromagnetic power of the electric machine from the second value exceeds a predefined power threshold value, the torque of the electric machine, calculated on the basis of the machine model, is classified as implausible.
